JP 2012-1185 A

  However, in the apparatus described in Patent Document 1 described above, the driving operation is evaluated for each of the plurality of traveling scenes regardless of the traveling state in which the vehicle has actually reached (for example, traveling on a highway or traveling on a traffic jam). Displayed. In this regard, for example, when a vehicle continues to travel on a highway, the vehicle has little opportunity to accelerate (start) from the stopped state or decelerate until it stops. A situation occurs in which the evaluation of the driving operation is performed and displayed. Further, for example, when the vehicle encounters a traffic jam, there is a situation where the driving operation is evaluated and displayed in a constant speed traveling scene even though the vehicle has almost no opportunity to travel at a constant speed. Therefore, in the apparatus described in Patent Document 1 described above, since the driving operation is evaluated and displayed even in a driving scene where the vehicle is difficult to reach, the processing load necessary for the calculation is always very high. .

  The present invention has been made in view of the above-described points, and provides a vehicle driving evaluation apparatus and a vehicle driving evaluation method capable of reducing processing load by unnecessaryly evaluating driving operations. For the purpose.

This is achieved by a vehicle driving evaluation device.

  In addition, the above object is to provide a first step for determining which of a plurality of travel scenes the traveling state of the host vehicle belongs to, and a second step for detecting a driving operation performed by the host vehicle driver. A step, a third step of evaluating the driving operation detected in the second step for each of the travel scenes determined in the first step, and a road environment in which the host vehicle travels is detected. A fourth step and a fifth step of stopping the evaluation of the driving operation in the third step in the traveling scene where the host vehicle is difficult to reach according to the road environment detected in the fourth step. Is achieved by a vehicle driving evaluation method.

  In the present invention, “evaluation of driving operation” refers to eco-driving diagnosis, safe driving diagnosis, driving technology diagnosis, and the like. “Cancellation of evaluation” includes stopping scoring and scoring of driving operations, and not acquiring data necessary for scoring and scoring.

  In addition, the above object is to provide a driving scene determination unit that determines which driving scene the host vehicle belongs to and a driving operation detection that detects a driving operation performed by the driver of the host vehicle.

  Hereinafter, specific embodiments of a vehicle driving evaluation apparatus and a vehicle driving evaluation method according to the present invention will be described with reference to the drawings.

  FIG. 1 shows an overall configuration diagram of a system 12 including a vehicle driving evaluation apparatus 10 according to a first embodiment of the present invention. Moreover, FIG. 2 shows the detailed block diagram of the vehicle driving | running evaluation apparatus 10 of a present Example. The vehicle driving evaluation device 10 according to the present embodiment is mounted on a vehicle 14 such as a gasoline vehicle, a hybrid vehicle, or an electric vehicle, for example, and is a device that evaluates the driving operation of the driver of the mounted vehicle 14.

  As shown in FIG. 1, the system 12 according to the present embodiment includes a vehicle driving evaluation device 10 mounted on a vehicle 14, a center 16, and a communication network 18. The center 16 is a device that collects or generates various information by communicating with the vehicle driving evaluation device 10 via the communication network 18 for each vehicle 14. The communication network 18 is an internet network for wirelessly connecting the vehicle driving evaluation apparatus 10 and the center 16.

  The vehicle driving evaluation device 10 includes an electronic control unit (hereinafter referred to as an evaluation ECU) 20 that performs control for evaluating an eco-driving degree indicating an economic index of the driving operation of the host vehicle driver. Note that the evaluation ECU 20 may also be used as a navigation ECU that detects the position of the host vehicle. A travel control ECU 26 that controls the travel of the host vehicle is connected to the evaluation ECU 20 via an in-vehicle LAN 24 such as a CAN (Controller Area Network).

  The travel control ECU 26 is an HV-ECU mounted on a hybrid vehicle or an engine ECU mounted on a gasoline vehicle, and includes sensors such as an accelerator opening sensor, a brake pedal switch, an ignition switch, a shift position sensor, and a cruise control switch. It is connected to a switch and a brake ECU 30 that controls braking of the host vehicle via an in-vehicle LAN 28 such as CAN.

  The brake ECU 30 detects the rotation amount of the wheel per unit time using a vehicle speed sensor provided for each wheel, detects the vehicle speed of the host vehicle based on the rotation amount of each wheel, and rotates the wheel of each wheel. Control braking of the vehicle based on the amount and the vehicle speed. Information indicating the vehicle speed of the host vehicle detected by the brake ECU 30 is supplied to the travel control ECU 26 via the in-vehicle LAN 28.

  The travel control ECU 26 detects the accelerator opening, accelerator on / off, ignition on / off, brake pedal on / off, shift position, cruise control signal status, etc., based on signals from various sensors and switches. At the same time, on the basis of the detected values and the vehicle speed acquired from the brake ECU 30, the traveling of the host vehicle is controlled, and further, the display of the eco-drive indicator in the meter is controlled. Note that this vehicle travel control is, for example, controlling the output of an electric motor or an engine. In addition, the display control of the eco-drive indicator is, for example, controlling on / off of the eco-drive indicator lamp that informs whether or not the host vehicle is in eco-drive, and the current accelerator opening and the range of eco-drive The display of the eco-drive indicator zone (eco-zone state quantity) to be displayed while comparing is controlled.

  Information indicating various detection values acquired by the travel control ECU 26 is supplied to the evaluation ECU 20 via the in-vehicle LAN 24. The evaluation ECU 20 has a scene manager unit 32. The scene manager unit 32 determines the traveling state of the host vehicle based on information from the traveling control ECU 26. Specifically, it is determined whether the traveling state of the host vehicle belongs to a plurality of traveling scenes based on vehicle speed, accelerator opening, on / off of a brake pedal, and the like.

  In the present embodiment, the traveling scene described above includes a state in which the host vehicle accelerates (acceleration state), a state in which the host vehicle travels in a steady state (steady traveling state), and a state in which the host vehicle decelerates (deceleration state). It is divided into three states. The acceleration state only needs to include a start state in which the host vehicle accelerates from the stopped state. When the host vehicle reaches a predetermined vehicle speed (for example, 20 km / h) from the stopped state, the host vehicle accelerates afterwards. Any device that is determined to be in the state may be used. Further, the steady running state only needs to include a stable running state in which the host vehicle starts and reaches a predetermined vehicle speed and then travels within a certain speed range, and the host vehicle speed is within the predetermined speed range. If it is determined that the host vehicle is in a steady running state. Further, the deceleration state only needs to include a state from when the host vehicle stops until it stops, and when the host vehicle stops from the steady driving state, it is determined that the host vehicle was in a deceleration state afterwards. Anything is acceptable.

  The evaluation ECU 20 also has an eco degree calculation unit 34 connected to the scene manager unit 32. Information indicating the traveling state of the host vehicle determined by the scene manager unit 32 is supplied to the eco degree calculation unit 34. The eco degree calculation unit 34 is a part that calculates the eco driving degree of the driving operation by the driver for each driving scene. The eco-degree calculation unit 34 uses the driver's accelerator operation (for example, accelerator opening, eco-zone state quantity (eco-drive indicator), accelerator-off time), etc. as input values for each driving scene. Score the degree of eco-driving. That is, for each traveling scene, the eco-driving degree is scored between 0 and 100 points according to a predetermined method. For example, in the deceleration state, a score is given according to the time from when the accelerator pedal is switched on to off until the host vehicle stops, and the longer the time, the higher the score.

  The eco degree calculation unit 34 performs (1) scoring in the acceleration state when it is determined that the traveling state of the host vehicle is the acceleration state, that is, when the host vehicle reaches a predetermined vehicle speed from the stopped state. The operation is mainly performed based on the accelerator operation that is input and stored until the vehicle reaches a predetermined vehicle speed from the stop state. Further, (2) scoring in a steady running state is performed every predetermined time (for example, 2 seconds) when the vehicle starts to reach a predetermined vehicle speed and then travels within a predetermined speed range. This is mainly based on the accelerator operation input and stored during the time. Further, (3) scoring in the deceleration state is performed when it is determined that the traveling state of the own vehicle is in the decelerating state, that is, when the own vehicle stops from the steady traveling state, and the own vehicle stops from the steady traveling state. This is mainly based on the accelerator operation that has been input and stored in between.

  The evaluation ECU 20 also includes a calculation unit 36 connected to the scene manager unit 32 and the ecological degree calculation unit 34. Information indicating the traveling state of the host vehicle determined by the scene manager unit 32 and information indicating the eco-driving degree of the driver's driving operation for each traveling scene calculated by the eco-degree calculating unit 34 are supplied to the calculating unit 36. Is done. Based on the information from the scene manager unit 32 and the information from the eco-degree calculation unit 34, the calculation unit 36 integrates the eco-driving degree for each driving scene, and calculates the total points for each driving scene. The advice regarding the driving operation which should be advised to the driver of the own vehicle is set based on the eco-driving degree and the total points for each driving scene.

  For example, if the time it takes for the vehicle to reach a predetermined vehicle speed from the stop state is short and the score in the acceleration state is relatively low, advice is given to operate the accelerator pedal loosely during acceleration. When the time required for the vehicle to stop from the steady running state is short and the score in the deceleration state is relatively low, advice is given to turn off the accelerator pedal slightly earlier during deceleration.

  The evaluation ECU 20 also has a display unit 38 connected to the calculation unit 36. The display unit 38 is a display unit that is visible to a driver or the like mounted on a navigation system or the like. The calculation unit 36 performs control for causing the display unit 38 to display a score obtained by scoring the degree of eco-driving for each traveling scene and the calculated total points. The scores and points displayed on the display unit 38 may be specific numerical values, but may be a bar graph in increments of 20 points as shown in FIG.

  Further, a DCM-ECU 42 constituting an in-vehicle communication device is connected to the evaluation ECU 20 via an in-vehicle LAN 40 such as CAN. The DCM-ECU 42 is an electronic control unit necessary for the vehicle driving evaluation apparatus 10 to communicate with the center 16 via the communication network 18, and is a probe traffic sent from the center 16 via the communication network 18. Information such as information is collected, and the collected information is supplied to the evaluation ECU 20 via the in-vehicle LAN 40.

  Note that the probe traffic information is road traffic information generated based on information such as the position where the vehicle actually traveled and the vehicle speed, for example, information indicating the degree of congestion and congestion generated using the vehicle speed, , Weather information generated using the presence / absence of wiper operation, fuel consumption information generated using the presence / absence of brake operation, and the like. The probe traffic information can be generated not only on the main trunk road but also on a narrow street if the vehicle actually travels.

  Next, with reference to FIG.4 and FIG.5, the characteristic operation | movement of the vehicle operation evaluation apparatus 10 of a present Example is demonstrated.

  FIG. 4 shows a flowchart of an example of a control routine executed by the evaluation ECU 20 in the vehicle driving evaluation apparatus 10 of the present embodiment. FIG. 5 is a diagram showing an example screen displayed on the display 38 when the host vehicle travels on an expressway or an automobile exclusive road in the vehicle driving evaluation apparatus 10 of the present embodiment.

  By the way, in the present embodiment, the traveling state of the vehicle belongs to one of three traveling scenes of an acceleration state, a steady traveling state, and a deceleration state. The acceleration state is determined to have occurred after the vehicle reaches the predetermined vehicle speed from the stop state, and the scoring in the acceleration state is memorized until the vehicle reaches the predetermined vehicle speed from the stop state. This is performed based on an accelerator operation or the like. Further, it is determined that the steady running state occurs when the vehicle starts and travels within a predetermined speed range after reaching a predetermined vehicle speed, and scoring in the steady running state is within the predetermined speed range. It is carried out at predetermined intervals during driving. Further, the deceleration state is determined to have occurred after the vehicle stops from the steady running state, and the scoring in the deceleration state is stored in the accelerator stored until the vehicle stops from the steady running state. This is done based on the operation.

  In this regard, it is necessary to always store the accelerator operation at each time point while driving the vehicle in order to always make the judgment of each driving scene while driving the vehicle and to score each driving scene. Then, a situation occurs in which the memory area is occupied for scoring, and the processing load (CPU load) necessary for the calculation is always very high. Therefore, in the present embodiment, in a road environment where the traveling state of the vehicle hardly changes, the calculation processing load is reduced by stopping the determination and scoring of the traveling scene where the vehicle is difficult to reach.

  In the vehicle driving evaluation apparatus 10 of the present embodiment, the evaluation ECU 20 executes the following processing in order to reduce the calculation processing load when evaluating the driving operation of the host vehicle driver. Specifically, first, information including the type of road on which the host vehicle travels is acquired (step 100). The information including the road type is, for example, information supplied from a navigation system or an ETC onboard device mounted on the host vehicle, and includes a GPS positioning result, a driving plan of the host vehicle, a driving route to the destination, or For example, whether or not the ETC gate passes.

  Based on the information acquired as described above, the evaluation ECU 20 determines whether or not the host vehicle is traveling on an expressway or an automobile-only road, that is, whether the road on which the host vehicle is actually traveling is an expressway or an automobile-only road. It is determined whether or not (step 110). Note that “the host vehicle is located on the expressway or automobile exclusive road” means that the host vehicle enters the expressway or automobile exclusive road and reaches the exit.

  As a result, the vehicle is not located on the expressway or automobile road because the vehicle is not located on the expressway or automobile road or the vehicle does not pass through the ETC entrance gate. Alternatively, if it is determined that the vehicle is not traveling on an automobile-only road, the processing of this routine is terminated without any further processing. In this case, thereafter, as usual, all the points obtained by scoring the eco-driving degree for each traveling scene and the calculated total points are displayed on the display unit 38 as shown in FIG.

  On the other hand, the evaluation ECU 20 determines in step 110 that the own vehicle is located on the highway or the exclusive road because the own vehicle is located on the highway or the exclusive road or the own vehicle has passed the ETC entrance gate. If it is determined that the vehicle is traveling on an expressway or a motorway, the next step is to mask both the scoring of the eco-driving degree in the acceleration state and the scoring of the eco-driving degree in the deceleration state (Mask processing) is performed (step 120). When such mask processing is performed, both the acceleration state presence / absence determination itself and the deceleration state presence / absence determination itself are both canceled, and the scoring in the acceleration state and the scoring in the deceleration state are both stopped. Thereafter, only the presence / absence determination of the steady running state among the plurality of running scenes is performed, and only scoring of the eco-driving degree in the steady running state is performed.

  Further, after the process of step 120, the evaluation ECU 20 determines whether or not an exception process (that is, the mask process is not executed) is required for the mask process in the acceleration state and the deceleration state described above (step). 130). For example, when the vehicle travels just before a rest area such as a service area or a parking area on an expressway or a car road, the car travels from the main line to a rest area on the motorway or car road. When exiting or converging from a resting place to the main line, when the host vehicle runs on the expressway or car road in front of or behind the main toll gate or ticket gate, or when the car is on the motorway or car road It may be performed when a traffic jam is encountered, and the necessity of the exception processing may be determined based on the GPS positioning result, probe traffic information from the center 16, or the like.

  If the evaluation ECU 20 determines that the above exception processing is necessary, the evaluation ECU 20 temporarily cancels the mask processing in the acceleration state and the deceleration state described above (step 140). When such a temporary release is performed, during the release, both the acceleration state determination and the deceleration state determination are performed, and the scoring in the acceleration state and the scoring in the deceleration state are included. Scoring of eco-driving degree in all driving scenes will be implemented.

  If the evaluation ECU 20 executes the process of step 140 or determines that the exception process is not required in step 130, the evaluation ECU 20 next selects the road on which the own vehicle from the navigation system or the ETC onboard device actually travels. Based on the information including the type, it is determined whether or not the own vehicle has exited from the expressway or the automobile exclusive road, that is, whether or not the road on which the own vehicle actually travels is no longer an expressway or an automobile exclusive road (step 150). ). As a result, if it is determined that the vehicle is not yet out of the expressway or automobile road because the vehicle is on the expressway or automobile road or the vehicle does not pass through the ETC exit gate. Next, the process of step 120 is repeatedly executed.

  On the other hand, in step 150, the evaluation ECU 20 leaves the vehicle from the expressway or the automobile-only road because the vehicle position is not on the expressway or the automobile-only road or the vehicle has passed through the ETC exit gate. When it is determined that the state has shifted from the state located on the expressway or the automobile exclusive road to the state not located, the mask processing in the acceleration state and the deceleration state described above is canceled (step 160). After such cancellation, both the acceleration state presence determination and the deceleration state presence determination are resumed, and all the driving scenes including the above scoring in the acceleration state and the above scoring in the deceleration state are performed. The eco-driving degree will be scored.

  As described above, in the vehicle driving evaluation apparatus 10 of the present embodiment, when the own vehicle is located on the expressway or the automobile exclusive road and travels on the expressway or the automobile exclusive road, in principle, the acceleration by the evaluation ECU 20 The determination of the presence or absence of the state and the deceleration state and the scoring of the eco-driving degree of the driving operation in the acceleration state and the deceleration state are each stopped, and the display of the evaluation in the acceleration state and the deceleration state on the display 38 is suppressed. The suppression of the display is to make the display of the evaluation of the eco-driving degree in the acceleration state and the deceleration state less noticeable than usual. For example, the display itself is stopped, and the character color to be displayed This is a concept that includes changing (thinning) the vehicle more than usual, changing the background color more than usual, transitioning to a dedicated highway screen different from the normal screen, and the like.

  In general, since a vehicle traveling on a highway or an automobile exclusive road has almost no chance of stopping, the vehicle is hardly decelerated until the vehicle stops, and then starts to accelerate. For this reason, when the host vehicle is traveling on an expressway or an automobile exclusive road as described above, the evaluation ECU 20 determines whether or not the vehicle is in an accelerated state and a decelerated state, and scores for the eco-driving degree of the driving operation in the accelerated state and the decelerated state. Even if the control is stopped and the display of the evaluation in the acceleration state and the deceleration state on the display 38 is suppressed, there is no inconvenience for the own vehicle driver, and the evaluation information is useless to the own vehicle driver. Will not be offered.

  Therefore, according to the vehicle driving evaluation apparatus 10 of the present embodiment, the driving operation in the driving scene (specifically, the acceleration state and the deceleration state) that is difficult to reach when the host vehicle is traveling on the highway or the automobile exclusive road. By unnecessarily performing the evaluation, it is possible to suppress the situation where the memory area is occupied for scoring in the traveling scene, and it is necessary for scoring calculation in the traveling scene by the evaluation ECU 20 Processing load can be reduced. For this reason, it is possible to lower the CPU specification in the evaluation ECU 20, and it is possible to reduce the cost of the system (navigation).

  Further, in the vehicle driving evaluation device 10 of the present embodiment, the host vehicle is positioned on the expressway or the automobile exclusive road and travels on the expressway or the automobile exclusive road, whereby the evaluation ECU 20 performs the acceleration state and the deceleration state. After the determination of the presence / absence and scoring of the eco-driving degree of the driving operation in the acceleration state and the deceleration state are each stopped and the display of the evaluation in the acceleration state and the deceleration state on the display 38 is suppressed, the own vehicle is in the expressway Alternatively, when the vehicle exits a motorway, cancellation of the acceleration / deceleration state determination and cancellation of scoring of the eco-driving degree of the driving operation in the acceleration state and the deceleration state are canceled, and the acceleration state to the display 38 And the suppression of the evaluation display in the deceleration state is released.

  In general, a vehicle that has stopped traveling on a highway or an automobile-only road may stop and may reach a deceleration state or an acceleration state. Therefore, in this case, the evaluation ECU 20 determines whether or not the acceleration state and the deceleration state exist, and scores the eco-driving degree of the driving operation in the acceleration state and the deceleration state, respectively. It is convenient for the driver of the vehicle to display the evaluation. Therefore, according to the present embodiment, it is possible to reliably evaluate the driving operation and provide information to the driver of the host vehicle for a driving scene that may be reached by the host vehicle.

  In the vehicle driving evaluation apparatus 10 according to the present embodiment, even when the host vehicle travels on an expressway or an automobile exclusive road, a condition for temporarily canceling the mask processing in the acceleration state and the deceleration state is satisfied (for example, When the vehicle travels on the expressway or car road just before the rest area such as the service area or parking area, the car exits from the main line to the rest area on the motorway or car road or rests on the contrary When the vehicle joins the main line, when the host vehicle runs around the main toll gate or ticket gate on the expressway or car road, or the car encounters traffic jam on the motorway or car road )) Exceptionally, the evaluation ECU 20 determines whether or not there is an acceleration state and a deceleration state, and all the travelings including the acceleration state and the deceleration state are performed. Be carried score of eco-driving degree of driving operation by chromatography down, display the evaluation at every running scene including acceleration state and the deceleration state of the display 38 is implemented.

  In general, immediately before a resting place on a highway or an automobile-only road, the vehicle may leave the resting place from the main line, so that the vehicle may be decelerated until it stops. In addition, after the vehicle stops at the resting place, the vehicle joins from the resting place to the main line, so there is a high possibility of starting and reaching an acceleration state. In addition, when passing through the main toll booth or the ticket gate, the vehicle may be in a decelerating state where the vehicle decelerates to a stop, or may start from the stopped state and reach an accelerated state. Furthermore, a vehicle that encounters a traffic jam on an expressway or an automobile-only road repeats stopping and starting, and thus is likely to reach a deceleration state and an acceleration state. For this reason, in this situation, the evaluation ECU 20 determines whether the acceleration state and the deceleration state exist, and scores the eco-driving degree of the driving operation in the acceleration state and the deceleration state, respectively. It is convenient to display each of the evaluations.

  Therefore, according to the vehicle driving evaluation apparatus 10 of the present embodiment, even when the host vehicle is traveling on an expressway or an automobile exclusive road, if exception processing is necessary, mask processing in the acceleration state and the deceleration state is performed. Is temporarily canceled, it is possible to avoid a situation in which the evaluation of the driving operation in the traveling scene in which the host vehicle may reach on the expressway or the automobile exclusive road is stopped. For this reason, the driving operation is reliably evaluated for a driving scene where the vehicle may reach, while the driving operation evaluation is stopped for a driving scene where the vehicle is difficult to reach to reduce the processing load. It is possible.

  In the first embodiment described above, the scene manager 32 of the evaluation ECU 20 determines the traveling state of the host vehicle based on information from the traveling control ECU 26 such as the vehicle speed, accelerator opening, and brake pedal on / off. By determining which of the travel scenes is divided into a plurality of sections, the “travel scene determination means” described in the claims is used by the travel control ECU 26 using the accelerator opening sensor or the like. By detecting a driving operation such as an accelerator operation performed by the “driving operation detecting means” described in the claims, the eco degree calculation unit 34 evaluates the driving operation by the driver for each driving scene. Thus, the “operation evaluation means” described in the claims is realized.

  Further, the evaluation ECU 20 obtains information including the type of road on which the host vehicle travels, and determines whether the host vehicle is traveling on an expressway or an automobile-only road. Patented by determining whether the vehicle's own vehicle exits from the main line to the resting place or joins from the resting place to the main line on the expressway or the motorway. When the “road environment detection means” and “rest area determination means” described in the claims determine that the host vehicle is traveling on an expressway or an automobile exclusive road, the driving operation in the acceleration state and the deceleration state is performed. When the evaluation is stopped and the “driving evaluation stopping means” described in the claims determines that the host vehicle is traveling on an expressway or an automobile exclusive road, the acceleration state on the display 38 and By suppressing the display of the evaluation in the deceleration state, the “display suppression means” described in the claims performs a mask process for masking scoring of the eco-driving degree in the acceleration state and the deceleration state in step 140 above. By temporarily canceling, the “suspended temporary canceling means” described in the claims cancels the mask processing for masking the scoring of the eco-driving degree in the acceleration state and the deceleration state in the above step 160. The “cancellation canceling means” described in the claims is realized.

  By the way, in said 1st Example, the exception process which cancels the mask process which masks scoring of the eco-driving degree in an acceleration state and a deceleration state, for example, the own vehicle is serviced on a highway or a motor vehicle exclusive road. When driving in front of a rest area such as an area or parking area, or when the vehicle leaves the main line to the rest area on the expressway or motorway, or conversely joins the rest area to the main line It will be implemented when driving around the main toll gate or the ticket gate on a road or car road. However, the present invention is not limited to this, and is more finely grained. When the own vehicle runs on a highway or an automobile exclusive road just before a resting place, a main toll gate, a ticket gate, or from the main line to a resting place. When exiting, the exception process that cancels only the mask process on the deceleration state side of the mask process that masks the scoring of the eco-driving degree in the acceleration state and the deceleration state is performed, and the mask process on the acceleration state side is performed. It may be continued. In addition, the degree of eco-driving in the acceleration and deceleration states when the host vehicle merges from the resting place to the main line on the expressway or motorway, or passes immediately after passing through the main toll gate and the ticket gate Of the mask processing for masking the scoring, the exception processing for canceling only the mask processing on the acceleration state side may be performed, and the mask processing on the deceleration state side may be continued.

  In the first embodiment, the vehicle is located on the highway or the automobile-only road because the vehicle is located on the expressway or the automobile-only road or when the vehicle has passed the ETC entrance gate. Then, when it is determined, the mask processing for masking both the scoring of the eco-driving degree in the acceleration state and the scoring of the eco-driving degree in the deceleration state is executed, and after starting the mask processing, The vehicle is not located on the expressway or the motorway because it is not on the expressway or the motorway, or because the host vehicle has passed through the ETC exit gate. When it is determined that the state has shifted to the state, the above-described mask processing is canceled, but the present invention is not limited to this, and the above-described mask processing is performed. If the vehicle approaches the exit (for example, a toll gate) of the expressway or automobile exclusive road from the state where the vehicle is located on the expressway or automobile exclusive road Good. According to such processing, regarding the deceleration that occurs when the host vehicle travels on the main road of an expressway or an automobile exclusive road and then approaches the exit, it is determined whether there is a deceleration state and the eco operation of the driving operation in the deceleration state Since the degree is scored and the display 38 displays the evaluation in the deceleration state, the driving operation when the vehicle decelerates toward the exit of the expressway or automobile road is surely evaluated. Can be implemented.

  In the above modification, the mask process for masking scoring of the degree of eco-driving in both the acceleration state and the deceleration state is canceled when the host vehicle approaches the exit of the expressway or the automobile exclusive road. It is sufficient to cancel at least the mask processing on the deceleration state side. That is, when the host vehicle approaches the exit of an expressway or an automobile exclusive road, only the deceleration state mask processing of the acceleration state side mask processing and the deceleration state side mask processing is canceled, and the acceleration state side This masking process may be continued. In this configuration, when the host vehicle exits from an expressway or an automobile exclusive road, the mask processing on the acceleration state side may be canceled.

  In the first embodiment, the mask process for masking the scoring of the degree of eco-driving in both the acceleration state and the deceleration state when it is determined that the host vehicle is located on an expressway or an automobile road. However, the mask processing may be started only after the host vehicle passes through the entrance of the expressway or the exclusive road for the automobile and then enters the main line. According to such processing, with respect to the acceleration that occurs when the host vehicle passes through the entrance of the expressway or automobile exclusive road and merges with the main line, the presence / absence of the acceleration state is determined and the eco-driving degree of the driving operation in the acceleration state is determined. Since the scoring is performed and the display of the evaluation in the acceleration state is performed on the display 38, the driving operation when the host vehicle heads to the main road of the expressway or the exclusive road for the automobile is surely performed. can do.

  In the above modification, a mask that masks the scoring of the degree of eco-driving in both the acceleration state and the deceleration state when the host vehicle passes through the entrance of the expressway or automobile road and enters the main line. First, when the host vehicle enters the entrance of the expressway or automobile road, the masking process on the deceleration side is started, and then the host vehicle enters the main road of the expressway or automobile road. In such a case, the mask processing on the acceleration state side may be started.

  Further, in the first embodiment described above, “the own vehicle is located on the expressway or automobile exclusive road” means that the own vehicle enters the expressway or automobile exclusive road and reaches the exit. Although defined as being, the present invention is not limited to this, and it may be defined that the host vehicle is located on the main line of a highway or an automobile exclusive road.

  FIG. 6 shows a flowchart of an example of a control routine executed by the evaluation ECU 20 in the vehicle driving evaluation apparatus 10 according to the second embodiment of the present invention. The vehicle driving evaluation apparatus 10 of the present embodiment is realized by causing the evaluation ECU 20 to execute a routine shown in FIG. 6 instead of the routine shown in FIG.

  That is, in the vehicle driving evaluation apparatus 10 of the present embodiment, the evaluation ECU 20 executes the following processing in order to reduce the calculation processing load in evaluating the driving operation of the host vehicle driver. Specifically, first, the road situation including the road on which the host vehicle travels is grasped (step 200). This road condition is, for example, probe traffic information supplied from the center 16 to the DCM-ECU 42 via the communication network 18, or VICS (registered trademark) information received using an FM receiver, Is information on whether or not there is a traffic jam that can only be traveled below a predetermined speed.

  Then, the evaluation ECU 20 determines whether or not the host vehicle is traveling on a congested road based on the road condition grasped as described above, that is, whether or not the road on which the host vehicle actually travels is a traffic jam section. A determination is made (step 210). As a result, if it is determined that the host vehicle is not traveling on a congested road, the processing of this routine is terminated without any further processing. In this case, thereafter, all the points obtained by scoring the eco-driving degree for each traveling scene and the calculated total points are displayed on the display unit 38 as usual.

  On the other hand, if it is determined in step 210 that the host vehicle is traveling on a congested road, the evaluation ECU 20 next performs a mask process for masking scoring of the eco-driving degree in the steady traveling state (step). 220). When such mask processing is performed, the determination of the presence or absence of the steady running state itself is stopped, and the scoring in the steady running state is stopped. In addition, the presence / absence determination of the deceleration state is performed, and only scoring of the eco-driving degree in the acceleration state and the deceleration state is performed.

  When the evaluation ECU 20 performs the process of step 220, next, the evaluation ECU 20 determines whether or not the own vehicle has exited the traffic jam section based on the road conditions including the road on which the own vehicle actually travels (step 230). . As a result, if it is determined that the host vehicle is still traveling in a traffic jam section, the process of step 210 is repeated. On the other hand, for example, when the own vehicle reaches a predetermined vehicle speed (for example, 40 km / h) or more and the position of the own vehicle is not a traffic jam section or the own vehicle has changed the route from the road in the traffic jam section to another road, If it is determined that the vehicle is traveling normally after passing through the traffic jam section, the mask processing in the steady traveling state is canceled (step 240). When such cancellation is performed, the determination of whether or not the vehicle is in a steady driving state is resumed, and scoring of the degree of eco-driving in all driving scenes including the above scoring in the steady driving state is performed. Become.

  As described above, in the vehicle driving evaluation device 10 of the present embodiment, when the host vehicle travels in a traffic jam section, the evaluation ECU 20 determines whether or not there is a steady running state and the eco-driving degree score of the driving operation in the steady running state. And the display of the evaluation in the steady running state on the display 38 is suppressed. The suppression of the display is to make the display of the evaluation of the eco-driving degree in the steady driving state less noticeable than usual. For example, the display itself is stopped, and the character color to be displayed is set to normal. It is a concept including changing (decreasing) more than that, changing the background color more than usual.

  In general, since a vehicle traveling on a congested road repeats stopping and starting, the vehicle rarely continues traveling at a predetermined vehicle speed or higher and hardly reaches a steady traveling state in which the vehicle travels within a predetermined speed range. Therefore, when the host vehicle is traveling in a traffic jam section as described above, the evaluation ECU 20 determines whether or not the steady driving state is present and scoring the eco-driving degree of the driving operation in the steady driving state, respectively, and the display 38 Even if the display of the evaluation in the steady running state is suppressed, there is no inconvenience for the host vehicle driver, and the evaluation information is not provided to the host vehicle driver wastefully.

  Therefore, according to the vehicle driving evaluation apparatus 10 of the present embodiment, the evaluation of the driving operation in the driving scene (specifically, the steady driving state) that is difficult to reach when the host vehicle travels in the congested traffic area is not possible. By not performing it as necessary, it is possible to suppress the situation where the memory area is occupied for scoring in the traveling scene, and the processing load necessary for scoring calculation in the traveling scene by the evaluation ECU 20 is reduced. Can be reduced. For this reason, it is possible to lower the CPU specification in the evaluation ECU 20, and it is possible to reduce the cost of the system (navigation).

  On the other hand, a vehicle that has passed through a traffic jam section may continue traveling at a predetermined vehicle speed or higher, and may reach a steady traveling state. For this reason, in this case, the evaluation ECU 20 determines whether or not there is a steady running state and scores the eco-driving degree of the driving operation in the steady running state, respectively, and displays the evaluation in the steady running state on the display 38. This is convenient for the driver of the vehicle. Therefore, according to the present embodiment, it is possible to reliably evaluate the driving operation and provide information to the driver of the host vehicle for a driving scene that the host vehicle may reach.

  In the second embodiment described above, the evaluation ECU 20 recognizes the road situation including the road on which the host vehicle travels, and determines whether the host vehicle is traveling on a congested road. Patented by stopping evaluation of driving operation in the steady driving state when the “road environment detecting means” and “congestion determination means” described in the claims determine that the host vehicle is traveling in a traffic jam section The “driving evaluation stopping means” described in the claims suppresses the display of the evaluation in the steady running state on the display 38 when it is determined that the host vehicle is running in the traffic jam section. Each of the “display suppression means” described in 1) is realized.

  By the way, in the first and second embodiments described above, the position of the host vehicle is detected by using a navigation system mounted on the vehicle, but the present invention is not limited to this, and the vehicle occupant possesses it. It is good also as detecting using the application which portable terminals, such as a smart phone, to have.

  In the first and second embodiments described above, the DCM-ECU 42 that can be communicably connected to the evaluation ECU 20 via the in-vehicle LAN 40 is provided, and the vehicle driving evaluation device 10 and the center 16 are communicably connected via the communication network 18. However, the present invention is not limited to this, and a plurality of transmitters for transmitting information (infrastructure cooperation information, etc.) generated at the center 16 or the like to the vehicle 14 are provided on the road. When the vehicle driving evaluation device 10 of the vehicle has a receiver that receives information transmitted from the road transmitter when passing near the road transmitter, the vehicle is operated based on the information received by the receiver. The execution / cancellation of the operation evaluation may be controlled. In addition, a receiver for receiving information transmitted from a preceding vehicle and a following vehicle traveling before and after the host vehicle is provided, and execution / cancellation of evaluation of driving operation is controlled based on the information received by the receiver. It is good.

  Moreover, in said 1st and 2nd Example, the vehicle driving evaluation apparatus 10 classify | categorizes for every some driving | running | working scene, and evaluates the eco-driving degree which shows the economical parameter | index of the driving operation of the own vehicle driver. This is an eco-driving diagnosis. However, the present invention is not limited to this. For example, if the driving operation is evaluated by dividing it into a plurality of traveling scenes, for example, the degree of safe driving indicating the safety indicator of the driving operation is evaluated. A safe driving diagnosis may be performed, or a driving skill diagnosis may be performed to evaluate the degree of driving skill indicating an index of riding comfort of driving operation.

  For example, a plurality of driving scenes are classified into a straight traveling state where the host vehicle is traveling straight and a right / left turning state where the vehicle is turning left and right, and then a safe driving diagnosis is performed to evaluate the degree of safe driving based on steering operation and braking operation. However, on a highway or an automobile exclusive road, the evaluation (including data acquisition) in a right / left turn state may be stopped and only the evaluation in a straight traveling state may be performed. In addition, as a plurality of driving scenes, the vehicle is divided into a starting state in which the vehicle starts from a stopped state, a cruising state in which the vehicle travels within a predetermined speed range, and a decelerating state in which the vehicle decelerates. In the evaluation of the driving technology to be evaluated, the evaluation in the start state and the deceleration state (including data acquisition) may be stopped on the expressway or the exclusive road for automobiles, and only the evaluation in the cruise state may be performed.

  Furthermore, in the first embodiment, the vehicle driving evaluation device 10 stops the evaluation of the driving operation in the acceleration state and the deceleration state when the host vehicle travels on the expressway or the automobile exclusive road. In the second embodiment, the evaluation of the driving operation in the steady driving state is stopped when the host vehicle travels in the traffic jam section. Both the embodiments are shown as both in one embodiment. It is good also as what has a structure.
