Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used to manage the operation status of a vehicle. The present invention is applicable to trucks, buses,
Although it is a device developed to centrally manage the operation states of taxis and many other commercial vehicles, it can be widely used not only for business purposes but also for general vehicle operation management.

[0002]

2. Description of the Related Art A tachograph has been widely known as a device for automatically recording the operation status of a vehicle. The tachograph is a device that records the running speed in time series, and by checking this record, you can see the time when the car was running and the time when the car was stopped, as well as the time during traffic jams and during highway travel. Operation data such as the time of day can be collected.

In recent years, it has become possible to collect not only the running speed but also various operation data by using various sensors mounted on the vehicle. In particular, efforts have been made to improve fuel efficiency by using such an operation management system.

That is, the difference in fuel consumption between a plurality of vehicles having the same performance and traveling on the same route largely depends on the driving method of the driver. Therefore, there is an effort to notify the driver of fuel consumption information under the current driving conditions and also to give advice for further improving fuel consumption, for example, Japanese Patent Laid-Open No. 10-6.
Japanese Patent No. 9555 discloses an operation management system capable of urging the driver not to perform sudden acceleration or deceleration by notifying the driver of the time information when the driver suddenly accelerated or decelerated. .

[0005]

The advice to the driver for improving the fuel consumption in the conventional operation management system is merely to promote the reduction of the sudden acceleration and the sudden deceleration. There may be other factors that depend on and deteriorate fuel efficiency.

For example, when a driver accelerates a manual transmission vehicle, he or she performs an upshift operation while accelerating by depressing the accelerator. At this time, if the accelerator pedal is excessively depressed, the upshift operation is performed. Each time, the engine speed becomes over-rotated, which causes deterioration of fuel efficiency.

[0007] Alternatively, while traveling on a highway, if the inter-vehicle distance with the preceding vehicle is not appropriate, the operation of catching up with the preceding vehicle, approaching too soon, rushing to decelerate, accelerating again and catching up with the preceding vehicle is repeated. During this period, useless acceleration and useless deceleration are repeated. In this specification, such an operation is referred to as a wavy operation. Such wavy driving is not only dangerous but also a factor that deteriorates fuel efficiency. In addition, securing an inter-vehicle distance is a major point for safe driving even on ordinary roads, and has a great effect on fuel efficiency.

[0008] No operation management system is known that can provide advice for improving various driving methods that may cause such fuel consumption deterioration. In addition, JP-A-10-69
In the prior art disclosed in Japanese Patent No. 555, the driver is notified of the occurrence time of sudden acceleration or sudden deceleration.
There is no clear definition of sudden acceleration or deceleration. In addition, the parameters for defining sudden acceleration or sudden deceleration should naturally differ between when traveling on a general road and during traveling on a highway, and in the case of a truck, the same as above when loading luggage and when empty. The parameters should be different. However, the prior art does not disclose the technique of changing the parameter according to the situation.

The present invention has been made against such a background, and provides an operation management system and program capable of giving detailed advice to a driver regarding a driving method for improving fuel efficiency and safety. The purpose is to provide.

In the present invention, as shown in FIG. 1, the vehicle operation data including the vehicle speed and the engine rotation speed are sent to various sensors 2 and an ECU (Electronic Control Unit) 3.
And an in-vehicle device including an operation data detection unit 1 detected by the inter-vehicle distance detection device 12 and an IC card 5 storing the operation data detected by the operation data detection unit 1, and as shown in FIG. At an office, an IC card reading unit 6 that reads the recorded contents of the IC card 5, and an economical driving based on the operation data detected by the operation data detection unit 1 that is read from the IC card 5 by the IC card reading unit 6 The operation management system includes a business office device including a data analysis unit 7 that analyzes a situation and a data output unit 8 that outputs an analysis result by the data analysis unit 7.

Here, the features of the present invention are that the data analysis unit 7 has a wavy driving time counting unit 9 for counting the wavy driving time of the vehicle, and that the engine rotation speed of the vehicle is over-rotated due to the shift operation. An over-rotation frequency counting unit 10 that counts the number of times the vehicle has become unusable, and an inter-vehicle distance improper operating time counting unit 11 that counts the time when the inter-vehicle distance between the own vehicle and another vehicle becomes improper in correspondence with the vehicle speed. As shown in FIG. 3, the data output unit 8 includes a wavy operation time counting unit 9 and an over-rotation frequency counting unit 1.
0, the inter-vehicle distance improper operation time counting unit 11 counts the results and displays them as a form.

That is, as shown in FIGS. 3 (5) to 3 (7), the data output unit 8 includes a wavy operation time counting unit 9 and the number of over-rotation times for one driver over the time from the start time to the end time. The counting results of the counting unit 10 and the inter-vehicle distance improper operation time counting unit 11 are printed and displayed in a graph format on one sheet of paper. Further, as shown in FIG. 3A, the vehicle speed and the engine rotation speed displayed on the time axis for the time from the start of work to the end of work are printed together on the one sheet of paper. Further, as shown in FIGS. 3 (2) to 3 (4), the operating fuel consumption (2), which is the traveling distance per unit fuel, the idling time, and The fuel consumption (4) during the idling time and the traffic jam travel time (travel time below a predetermined speed) (3) are also printed and displayed.

More specifically, the data output unit 8 causes the wavy driving time counting unit 9 to count the wavy driving degree (%) = [(total value of unit time intervals T1 regarded as wavy driving) / (high speed driving). Total time)] ×
Graph data is displayed as 100. In the example of FIG. 3 (5), 2
The time to be considered as a wavy operation is 60 minutes for a high speed operation time of 00 minutes. The wavy driving degree in this case is 30
%, And this degree is displayed as a graph.

When the count result of the overspeed counter 10 is Ns, the engine speed overspeed per hour (/ h) is compared with the evaluation reference value Nm to obtain Ns / h / Nm ×. Graph data is displayed as 100. In the example of FIG. 3 (6), 1
Three times of engine over-revolution (3 times / h) are counted per hour, and the evaluation reference value Nm is set to 15 times of engine over-revolution (15 times / h) per hour. In this case, the degree of engine overspeed during the shift-up operation is 20%, and this degree is displayed as a graph.

The inter-vehicle distance danger degree (%) per total traveling time at the reference vehicle speed V1 or more of the counting result of the inter-vehicle distance improper operation time counting unit 11 is (cumulative time of M1 or more) / (cumulative time of V1 or more) Graph data is displayed as the ratio of. In the example of FIG. 3 (7), 280 minutes are counted out of 350 minutes. In this case, the inter-vehicle distance improper operation degree is 80%, and this degree is displayed as a graph.

Next, the calculation procedure in each counting unit will be described. As shown in FIGS. 4 and 5, the wavy operation time counting unit 9 detects the time interval D detected by the operation data detecting unit 1.
The increase amount DV or the decrease amount DV of the vehicle speed over t is calculated, and the calculation result is compared with the reference value A1 or A2 of the increase amount DV or the decrease amount DV of the vehicle speed over the time interval Dt, and the comparison result is referred to. When the calculation result indicates that the reference value has been exceeded, it is determined that the vehicle is in a wavy operation that is unnecessarily accelerated or unnecessarily decelerated above a certain standard.
That is, assuming that the previous vehicle speed vn + 1 and the current vehicle speed vn in the time interval Dt are DV = vn + 1−vn> 0, and if | DV |> A1, useless acceleration over the reference value If DV = vn + 1-vn <0 and | DV |> A2, it is determined that the deceleration is a wasteful deceleration equal to or higher than the reference value. Further, as shown in FIG. 6 as a result of this determination, useless acceleration / deceleration above the reference causes unit time interval T1 in the high-speed traveling section.
If it occurs even once, T1 is counted as the time when the wavy operation occurs.

When the shift-up operation is performed, as shown in FIG. 7, the abrupt increase / decrease of the engine rotation speed is repeated in a short time. The over-revolution counter 10 observes this and detects over-revolution of the engine speed during the upshift operation. That is, the engine rotation speed detected by the operation data detection unit 1 is observed, and as shown in FIG. 8, the maximum value Np that exceeds the over reference value Nu of the engine rotation speed is specified by referring to this observation result, and the maximum value is detected. The minimum value Npn of the engine speed is specified by referring to the observation result within a predetermined time after the time when Np is specified, and the maximum value Np and the minimum value Np are specified.
The number of times that a situation in which the difference DN from n is equal to or greater than the step reference value Nd occurs is counted. Actually, as shown in FIG. 8, as a result of observation within a predetermined time after the maximum value Np is specified, the value N
If p + 1 and Np + 2 are observed, these two values Np
+1 and Np + 2 are compared, and the smaller value Np + 1 is set to the minimum value N.
pn.

As shown in FIG. 9, the inter-vehicle distance improper operation time counting section 11 uses the vehicle speed data and the inter-vehicle distance data detected by the operation data detecting section 1 as a reference inter-vehicle distance M1 corresponding to the vehicle speed per unit time. Is calculated (S1, S2), the inter-vehicle distance data is compared with M1, and the inter-vehicle distance data is M.
If it is smaller than 1, it is regarded as improper (S3), and the integrated value is counted as the improper inter-vehicle distance time (S3).
4). In other words, when a vehicle is driving in a hurry ahead while overtaking multiple front vehicles on a highway, etc., the vehicle continues to accelerate uselessly and approaches the previous vehicle to a distance where the inter-vehicle distance becomes inappropriate, Tries to keep unnecessary distance or keep away from the vehicle. Further, the vehicle changes its course to an overtaking lane or the like to accelerate, then catches up with another preceding vehicle, and then decelerates and changes its course. By observing the occurrence of such unnecessary acceleration / deceleration, the inter-vehicle distance improper time is detected.

Further, as shown in FIG. 10, the data analysis unit 7 changes some or all of the parameters including the reference values A1 and A2 and the reference value Nu according to the vehicle speed and / or the load.

That is, the average speed is calculated based on the vehicle speed data (S11), and as a result, it is determined whether or not the traveling section to be analyzed is the high-speed traveling section (S12), and it is determined that it is the high-speed traveling section. If the baggage loading state at that time is empty (S13), it can be seen that the vehicle easily accelerates and has the highest acceleration.
1, the reference values A1 and A2 for detecting the wavy operation are set as "large". Further, since the acceleration is high and it is expected that the increase in the engine speed accompanying the shift-up operation will not be so large, the over reference value Nu is set to "medium" (S14). Even if it is a high-speed traveling section (S12), if luggage is loaded (S12)
13) Since the vehicle becomes less accelerating than when it is empty, the reference values A1 and A2 for detecting wavy driving are set as "small" as class # 2. Further, since the engine speed is increasing at a high speed because the vehicle is traveling at a high speed and the acceleration is low, the over reference value Nu is set as "extra large" (S15). If it is not in the high-speed traveling section (S12) and it is not empty (S16), it can be seen that the vehicle is not accelerating from the beginning and the acceleration is low. The reference values A1 and A2 for detecting the wavy operation are set as "medium". In addition, since the acceleration is low, the increase in the engine speed accompanying the shift-up operation is expected to increase, but the vehicle speed is lower than that in the high-speed running section. ”
It is set to "large", which is slightly smaller than that of (S17).
Further, even if the vehicle is not in the high-speed traveling section (S12), if the vehicle is empty (S16), the vehicle has a higher acceleration compared to when the luggage is loaded. Therefore, as the class # 4, the reference value for detecting the wavy driving is set. Set A1 and A2 as "oversized".
Further, since the acceleration is high, it is expected that the increase in the engine speed due to the shift-up operation will be small. Therefore, the over reference value Nu is set as "small" (S18). In this way, the parameters can be set in accordance with the running state of the vehicle, so that the data analysis can be performed in accordance with the running state of the vehicle.

FIG. 11 shows an example of parameter setting criteria. In the example shown in FIG. 11, ◎ indicates “extra large”, ◯ indicates “large”,
Δ represents “medium” and × represents “small”. Moreover, since the wavy driving mainly occurs during traveling on the highway, the detection may be limited to the high-speed traveling section. Furthermore, the detection accuracy and the processing time can be adjusted to desired values by appropriately changing the time interval Dt and the unit time interval T1. Further, the step reference value Nd may be changed together with the over reference value Nu.

The operation management system of the present invention can be realized by using a computer device as an information processing device. That is, when installed in a computer device, the computer device detects the operation data of the vehicle including the vehicle speed and the engine speed as a function corresponding to the on-vehicle device in the operation management system as shown in FIG. The function corresponding to the part 1 and the operation data detected by this detecting function are integrated into an IC.
The function corresponding to the operation data collection unit 4 stored in the card 5 is realized, and the IC card 5 is provided as a function corresponding to the office device in the operation management system as shown in FIG.
A function corresponding to the IC card reading unit 6 for reading the recorded contents of the data, and a data analysis unit 7 for analyzing the economical driving situation based on the operation data detected by the detecting function read from the IC card 5 by the reading function. By installing a program that realizes the function corresponding to the above and the function corresponding to the data output unit 8 that outputs the analysis result by the analyzing function into the computer device, the operation management system of the present invention is realized by using the computer device. Can be realized.

A feature of the program of the present invention is that, as functions corresponding to the data analysis unit 7, a first counting function corresponding to the wavy driving time counting unit 9 for counting the number of wavy driving of the vehicle, and a shift operation. A second counting function corresponding to the over-rotation number counting unit 10 that counts the number of times the engine speed of the vehicle becomes over-rotated, and counts the time when the inter-vehicle distance between the own vehicle and another vehicle becomes improper The third counting function corresponding to the inter-vehicle distance improper operation time counting section 11 is realized, and the counting results of the first, second, and third counting functions are provided as the output function as shown in FIG. It is in the place of realizing the function to display each.

As the displaying function, the first counting function is the time interval Dt detected by the detecting function.
