  Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating an example of the overall configuration of a driving support system 1 according to an embodiment of the present invention. The driving support system 1 includes a vehicle driving support device 10 and an information center 100.

  The vehicle driving support device 10 includes a navigation device 20 and a communication device 30. The navigation device 20 also includes a yaw rate sensor 50, a vehicle speed sensor 52, an inter-vehicle distance control ECU (Electronic Control Unit) 60, a rear warning control ECU 62, and a right turn assist control ECU 64 via the multiplex communication line 40. Is connected. Note that communication between devices via the multiple communication line 40 is performed using an appropriate communication protocol such as CAN (Controller Area Network), BEAN, or AVC-LAN.

  The navigation device 20 includes an integrated antenna 21, a memory 22, a display panel 23, a voice input / output device 24, and a navigation computer 25 as main components.

  The integrated antenna 21 is an antenna capable of transmitting and receiving various radio signals, receives GPS signals from GPS satellites, radio beacons related to road traffic information transmission services, ETC signals, etc., and outputs them to the navigation computer 25.

  The memory 22 is a storage medium such as a hard disk, a DVD (Digital Versatile Disk), or a CD-ROM, and stores map information. This map information is expressed in the form of nodes indicating intersections and links indicating roads.

  The display panel 23 is a display device that employs a VGA (Video Graphics Array) as a graphic system to display an image including a moving image and allows a user to perform various input operations as a touch panel. The display panel 23 detects a change in voltage caused by a user touching the surface of the display panel 23 and recognizes a position where the touch operation is performed. The display content of the display panel 23 is determined by the navigation computer 25, and the input operation performed on the display panel 23 is transmitted to the navigation computer 25.

  The voice input / output device 24 includes, for example, a microphone that can input voice and a speaker. The output content of the voice input / output device 24 is determined by the navigation computer 25, and the voice input to the voice input / output device 24 is input to the navigation computer 25.

  The navigation computer 25 is a computer unit in which, for example, a CPU, a ROM, a RAM, and the like are connected to each other via a bus, and includes an input / output interface, a timer, a counter, and the like. The ROM stores programs executed by the CPU and data. The navigation computer 25 includes a current position specifying unit 25A, a route guidance unit 25B, a communication control unit 25C, and a control content determination unit 25D as main functional blocks realized by using such a hardware configuration. Prepare.

  The current position specifying unit 25A specifies the current position (latitude, longitude, altitude) of the host vehicle by calculation based on the time difference between GPS signals. The current position specifying unit 25A corrects the current position of the host vehicle based on sensor output values input from the yaw rate sensor 50 and the vehicle speed sensor 52 and information included in the radio wave beacon received by the integrated antenna 21. In addition, correction may be performed based on information received by FM multiplex broadcasting, or correction based on a well-known map matching technique may be performed.

  The yaw rate sensor 50 detects the rotational angular velocity (yaw rate) in the vertical axis direction of the vehicle based on, for example, the distortion amount and direction of the piezoelectric ceramic, and outputs the rotational angular velocity (yaw rate) to the multiplex communication line 40. The vehicle speed sensor 52 is composed of, for example, a wheel speed sensor attached to each wheel and a skid control computer, and the skid control computer outputs a wheel speed pulse signal output from the wheel speed sensor to the vehicle speed rectangular wave pulse signal (vehicle speed signal). And output to the multiplex communication line 40.

  The route guidance unit 25B performs route guidance as a function of a normal navigation device. That is, the map information stored in the memory 22 indicates the recommended route from the current position of the host vehicle specified by the current position specifying unit 25A to the destination input by the user using the display panel 23 or the voice input / output device 24. Are set with reference to the above and stored in a storage medium such as an EEPROM. Then, image display and voice guidance using the display panel 23 and the voice input / output device 24 are performed so that the host vehicle travels according to the recommended route. In this embodiment, driver information transmitted from the information center 100 is referred to when setting a recommended route. Details will be described later.

  The communication control unit 25C transmits a request signal including the current position of the host vehicle specified by the current position specifying unit 25A to the information center 100 by transmitting an instruction signal to the communication device 30. The request signal is transmitted, for example, every predetermined time (for example, several [sec] to several [h]) while the host vehicle is traveling (or when the vehicle system is activated). Then, the driver information received by the communication device 30 as a response to the request signal is stored in the memory 22.

  Communication between the communication device 30 and the information center 100 is performed via the radio base station 80 and the network 90, for example. Between the communication device 30 and the radio base station 80, a mobile phone network, a PHS (Personal Handy-phone System) network, a wireless LAN, WiMAX (Worldwide Interoperability for Microwave Access), a satellite phone, a beacon, a TV or radio broadcasting network Etc. is used for wireless communication. The network 90 connecting the radio base station 80 and the information center 100 is a wired network such as a public switched telephone network (PSTN), a digital communication network (ISDN), or an optical fiber. For data transmission / reception, for example, HTTP (Hyper Text Transfer Protocol), FTP (File Transfer Protocol), MIME (Multipurpose Internet Mail Extension), etc., which are upward compatible with protocols such as TCP (Transmission Control Protocol) / IP (Internet Protocol), etc. Protocol is used.

  Accordingly, the communication device 30 includes, for example, a data communication antenna and a communication module. A Bluetooth-compatible mobile phone may be used, or a mobile phone may be mechanically connected. Further, a beacon transceiver, a TV or radio receiver, or the like may be used.

  Hereinafter, the information center 100 will be described. The information center 100 is configured based on information service facilities such as the police and traffic safety associations and broadcasting stations, for example, and includes a database 102, a center side communication device 104, a vehicle monitoring device 106, an information processing device 108, Is provided. Note that it is not necessary for all of these components to be installed in the same facility, and a configuration in which each component is connected through a network may be used.

  The database 102 stores past violation information (history of traffic violations made in the past) corresponding to the driver ID of the driver holding the driver's license, accident history, driving history, and the like. The information is updated in real time as a result of police enforcement or the like. The center side communication device 104 is a facility applicable to the above communication mode, and includes, for example, a modem, a communication terminal, a TV radio wave or radio wave transmission facility, and the like.

  The vehicle monitoring device 106 detects the current position of the traveling vehicle and the driver ID of the driver driving the vehicle by wireless communication or the like, and inputs them to the information processing device 108. Although there is no particular limitation on the specific mode of the vehicle monitoring device 106, for example, a driver that automatically shares the communication equipment between the communication device 30 and the information center 100 described above and is automatically transmitted from the traveling vehicle. The mode which detects an ID signal may be sufficient, and the mode which detects the beacon wave etc. which are transmitted from each vehicle by the infrastructure of a road end may be sufficient. Further, as in an existing automatic speed violation control device (commonly known as ORBIS), a camera for imaging a license plate may be installed at the road end and input to the information processing device 108. Needless to say, a plurality of these modes may be adopted at the same time.

  The information processing device 108 includes a temporary storage memory such as an EEPROM for sequentially storing the current position of the running vehicle detected by the vehicle monitoring device 106 in association with the driver ID. FIG. 2 is an example of a flowchart showing a processing flow of the information processing apparatus 108 when the center side communication apparatus 104 receives a request signal.

  First, the current position and the driver ID of a vehicle that is traveling in the “periphery” of the current position included in the request signal are extracted from the temporary storage memory (S200). Here, the “periphery” means, for example, a circular area having a radius of a predetermined distance, an elliptical area that is extended in the traveling direction of the vehicle that has transmitted the request signal, or a reference such as legal speed When it is assumed that the vehicle travels at a speed, it can be defined as an area where the required time is less than a certain time. In addition, it is naturally assumed that a plurality of vehicles and driver IDs traveling in the “periphery” are extracted (originally, only one may be extracted or may not be extracted at all).

  Then, the database 102 is searched using each extracted driver ID (S210), and various traffic violations and accident histories are summed up from the current vehicle position and past violation information and accident histories obtained as a result of the search. The driver information is generated by counting the number of times (S220), and the generated driver information is transmitted to the vehicle that has transmitted the request signal (S230). FIG. 3 is a diagram illustrating an example of a data format of original data sequentially stored in the database 102 and a data format of data created by the information processing apparatus 108 and transmitted as driver information. Thus, the communication load can be reduced by performing the aggregation process and transmitting the compact data as the driver information. As shown in the figure, the driver information may include a breakdown by link for setting a recommended route.

  Hereinafter, the description returns to the vehicle driving support device 10. Based on the driver information transmitted as described above, the route guide unit 25B sets a recommended route (if the recommended route has already been set, the recommended route may be changed). For example, (1) First, a temporary recommended route is created without considering the driver information (see FIG. 4A), and (2) All traffic violations and accidents in each link on the temporary recommended route. It is determined whether or not there is a dangerous link whose total history is equal to or greater than a predetermined number. (3) If a dangerous link exists, a route that bypasses the area is searched, and if there is a bypass route, the recommended route is determined by using the route (see FIGS. 4B and 4C). ). It should be noted that even if there is a detour route, it is desirable that the recommended route be created in more detailed cases, such as not adopting this if it is too far away. For example, a predetermined condition may be set for the estimated required time and the degree of increase in the total travel distance.

  People with violations such as traffic accidents, overspeeds, parking violations, etc. tend to repeat similar accidents and violations, so by avoiding the places where vehicles driven by these people are traveling, for example, the same Accidents and violations by perpetrators can be reduced. Therefore, as in this embodiment, by detecting a place where more than a predetermined number of vehicles driven by a driver who has made a traffic violation in the past are detected and setting a recommended route to circumvent this, an accident can occur in advance. Etc. can be prevented.

  Based on the driver information transmitted as described above, the control content determination unit 25D controls an in-vehicle device (in this embodiment, indicates the throttle motor 72 and the alert device 74) for performing the driving support operation. Various instruction signals are transmitted to the inter-vehicle distance control ECU 60, the rear warning control ECU 62, and the right turn assist control ECU 64 (that is, the control content is determined / changed).

  Here, the contents of the driving support control performed by each control ECU will be described. Each control ECU is, for example, a computer unit having a hardware configuration similar to that of the navigation computer 25 described above. Each control ECU may be integrated into a single unit, or may be integrated into other in-vehicle ECUs such as an engine control computer. In this embodiment, each control ECU will be described as independent.

  The inter-vehicle distance control ECU 60 is preset with an inter-vehicle distance from a vehicle (hereinafter referred to as a preceding vehicle) traveling in the same direction as the own vehicle in front of the own vehicle detected using the preceding vehicle detection device 71. The throttle motor 72 and the transmission are controlled so that the vehicle travels while maintaining the target inter-vehicle distance. The preceding vehicle detection device 71 is, for example, a millimeter wave radar device having a detection range in front of the host vehicle, using the time until the reflected wave of the millimeter wave returns, the angle of the reflected wave, and the frequency change, The distance, direction, speed, etc. of the object around the host vehicle are detected. An object having a predetermined size or more and moving in the same direction as the host vehicle is recognized as a preceding vehicle by the inter-vehicle distance control ECU 60. The preceding vehicle detection device 71 can be replaced by a laser radar, an infrared radar, a stereo camera device, or the like.

  In general, the target inter-vehicle distance is set in, for example, three levels of large, medium, and small by a user's operation of a hard switch or GUI (Graphical User Interface), voice input, and the like. Increase / decrease is changed based on the instruction signal. The control signal generated by the inter-vehicle distance control ECU 60 may be transmitted to the throttle motor 72 or the transmission via another on-vehicle ECU such as an engine control computer. Further, when there is no preceding vehicle within a predetermined distance ahead of the host vehicle, the inter-vehicle distance control ECU 60 adjusts the throttle opening and the gear position so that the vehicle travels while maintaining the set vehicle speed (constant speed traveling). control). The set vehicle speed is also set by the user in principle as with the target inter-vehicle distance, but may be increased or decreased based on an instruction signal from the navigation computer 25.

  The rear warning control ECU 62 is careful when a vehicle traveling in the same direction as the host vehicle (hereinafter referred to as a rear vehicle) is behind the host vehicle detected by the rear vehicle detection device 73 within a rear warning distance. The driver is alerted using the alerting device 74. The rear vehicle detection device 73 is, for example, a millimeter wave radar device whose detection range is the rear of the host vehicle, and the same replacement as the preceding vehicle detection device 71 is possible. The rear warning distance is set in advance and stored in the ROM or the like of the rear warning control ECU 62, for example, but is increased or decreased based on an instruction signal from the navigation computer 25. The alerting device 74 includes a buzzer, a speaker, a display / blink (flash) device, etc., and the voice input / output device 24 may be shared.

  The right turn assist control ECU 64 estimates the time (arrival time) until the oncoming vehicle detected by the oncoming vehicle detection device 75 reaches the intersection when the host vehicle tries to turn right at the intersection, and the arrival time is predetermined. When it is within the time and the front signal is blue, the warning device 74 makes an announcement to prompt the user to “wait for the oncoming vehicle to pass because the right turn is dangerous”.

  The navigation device 20 can determine that the host vehicle is about to turn right at the intersection. For example, the current position of the host vehicle specified by the current position specifying unit 25A is in the vicinity of an intersection (within a predetermined distance from the intersection), and the inclination of the wheel with respect to the vehicle body (steering angle) is greater than or equal to a predetermined angle by the output of the steering angle sensor. When facing right, it can be determined that the vehicle is about to turn right at the intersection. Then, if a positive determination is obtained, that fact may be output to the multiplex communication line 40. Further, the determination that the front signal is blue can be made by analyzing a captured image of a camera included in the oncoming vehicle detection device 75.

  The oncoming vehicle detection device 75 includes, for example, a combination of a camera that captures an image of the front of the host vehicle and a radar device. The arrival time can be calculated based on the speed and position of the oncoming vehicle detected by the radar device. In addition, in principle, the predetermined time is calculated based on the standard driver's driving ability and the size of the intersection every time a determination is made that the intersection is going to turn right (initial time with sufficient margin) The set value may be used), but is increased or decreased based on an instruction signal from the navigation computer 25.

  FIG. 5 is a flowchart showing a characteristic processing flow of the present invention executed by the navigation computer 25. This flow is executed every predetermined time (for example, in accordance with the transmission cycle of the request signal described above).

  First, as described above, a request signal is transmitted to the information center 100 (S300), and driver information transmitted from the information center 100 as a response thereto is received (S310).

  Next, the recommended route is set (or reset if already set) by the route guide unit 25B (S320). If no destination is set, no processing is performed.

  Whether the total number of accident histories is greater than or equal to the first predetermined number and the total number of parking violations is greater than or equal to the second predetermined number with reference to the driver information. (S330), if at least one of the conditions is satisfied, the inter-vehicle distance control ECU 60 is instructed to greatly change the target inter-vehicle distance currently used for control and to change the set vehicle speed small (S340). .

  It is considered that a driver with an accident history has a relatively high possibility of suddenly stopping without noticing the presence of a vehicle behind the vehicle because confirmation before and after the vehicle is neglected. There is also the possibility of being involved in a re-accident. On the other hand, it is considered that a driver who has made a parking violation has a relatively high possibility of suddenly stopping for parking on the street. Therefore, since it is considered that it is dangerous to travel with a relatively small inter-vehicle distance with respect to the vehicle driven by such a driver, the target inter-vehicle distance is largely changed. Furthermore, drivers with a history of accidents are considered to be relatively likely to jump out at intersections where there is no signal (temporary stop neglect), so reduce the set vehicle speed to drive more safety. It was decided. By these processes, it is possible to reduce the danger caused by a vehicle driven by a driver having an accident history or parking violation history traveling around the host vehicle.

  Subsequently, it is determined whether or not the total number of overspeed violations is greater than or equal to a third predetermined number (S350). If there are more than a predetermined number, the rear warning distance currently used for control is greatly changed. The rear warning control ECU 62 is instructed to do so (S360).

  Drivers who have violated overspeeding are generally considered to tend to travel at high speeds, so if there is a vehicle driven by such a driver in the vicinity of the vehicle, the possibility of a rear-end collision is relatively high it is conceivable that. Therefore, it was decided to greatly change the rear warning distance. By such processing, it is possible to reduce the danger caused by the vehicle driven by the driver who has a history of overspeed violation traveling around the host vehicle.

  Further, it is determined whether or not the total number of signal ignorances is equal to or greater than a fourth predetermined number (S370). If it is equal to or greater than the fourth predetermined number, a predetermined time (arrival time) currently used for control is determined. And the rear warning control ECU 62 is instructed to change the condition that the front signal is blue (S380), and one routine of this flow is terminated. That is, even if the front signal is actually not blue, it is regarded as blue for a while (several [sec] to several tens [sec]), and the predetermined time is greatly changed. In addition, the announcement may be changed to a stronger tone that prompts the user to wait for the oncoming vehicle to pass, or an instruction may be given to increase the volume.

  A driver who has neglected the signal is considered to be more likely to rush through even if the front signal turns yellow or red. If the driver is driving an oncoming vehicle while the host vehicle is making a right turn, it is desirable to start the right turn more carefully than usual. Therefore, even if the signal ahead changes to yellow or red, the warning system will continue for a while, and the predetermined time will be greatly changed in consideration of the possibility of oncoming vehicles accelerating before passing the intersection and passing through the intersection. It was decided to. By such processing, it is possible to reduce the danger caused by a vehicle driven by a driver having a history of ignoring signals traveling around the host vehicle.

  In addition, the said 1st-4th predetermined number is a conformity value, and may be determined arbitrarily. If a negative determination is obtained in any of S330, S350, and S370, no control is performed and one routine of this flow is terminated.

  According to the driving support system 1 and the vehicle driving support device 10 of the present embodiment described above, the driver information relating to the driver of the vehicle traveling around the host vehicle is acquired, and the violation information included in the driver information. In addition, the operating conditions of the driving support operation are appropriately determined in consideration of the accident history. Therefore, it is possible to reduce the danger caused by a vehicle driven by a driver having a history of violations or accidents traveling around the host vehicle and contribute to safe driving.

  In addition, if a vehicle driven by a driver with a history of violation or accident is driving around the vehicle, excessive driving support will be required if all driving support operations are positively performed uniformly. Although inconvenience may be caused by the operation, the vehicle driving support device 10 of the present embodiment determines the control content individually and specifically according to the type of violation information and accident history. Inconvenience will be suppressed.

  In addition, when a vehicle driven by a driver with a history of violation or accident is driving around the vehicle, the recommended route is set and changed so that it can be bypassed. Can drive.

  The best mode for carrying out the present invention has been described above with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. And substitutions can be added.

  For example, the determination of the control content based on the driver information exemplified in the embodiment is merely an example. Therefore, the control content may be arbitrarily determined as long as it is appropriate for the content of the driver information. For example, when there are a predetermined number or more of vehicles having an accident history (YES in the determination of S330 in the flowchart of FIG. 5), some instruction may be given to the rear warning control ECU 62 and the right turn assist control ECU 64.

  Further, the determination of the control content based on the driver information is not limited to changing the control threshold value or the operating condition as in the embodiment, but may be to change the degree of each driving support operation. Specifically, as suggested in the embodiment, the volume of the warning announcement may be changed to increase the warning effect, or the gain of the driving support operation related to the inter-vehicle distance control may be increased (for example, The adjustment amount of the throttle valve opening may be changed more greatly) and reflected in the vehicle behavior more quickly. Furthermore, on / off of each driving support operation may be determined.

  Moreover, acquisition of driver information is not necessarily limited to that acquired from the information center 100, and may be acquired through inter-vehicle communication.

  The driver information is not limited to that of the embodiment, and the original data registered in the database may be transmitted as it is. In this case, the control is not limited to the absolute number of traffic violation history and accident history as in the embodiment, but may be controlled based on the percentage of drivers having traffic violation history and accident history. In addition, some of the data items exemplified in the embodiments may be omitted, and a driver's unique driving rod or the like may be further included.

  Moreover, in the setting of the recommended route based on the driver information, the determination is made for each link. However, the same determination may be made for each predetermined region other than the link.

  In addition, the setting of the recommended route based on the driver information may be omitted.

  The present invention can be used in the automobile manufacturing industry, the automobile parts manufacturing industry, and the like.
