[0010] [Figure 1] FIG. 1 is a diagram showing an overall configuration of a driving status management system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, a number of embodiments for carrying out the present disclosure will be described with reference to the drawings. In each embodiment, the same reference numerals may be used to designate parts corresponding to matters described in the preceding embodiment, and duplicated descriptions may be omitted. In each embodiment, when only a part of the configuration is described, other embodiments described previously may be applied to other parts of the configuration. In addition to combinations of parts that are specifically indicated as being possible in each embodiment, it is also possible to partially combine embodiments even if not indicated, as long as there is no particular problem with the combination.

[0012] (First embodiment) A driving condition management system 100 according to a first embodiment is shown in Fig. 1. The driving condition management system 100 executes processing for operation management of a vehicle 20 owned by an establishment 120 engaged in vehicle operation, using a computer 121 in the establishment 120. The number of vehicles 20 in the establishment 120 may be, for example, one or more depending on the scale of the establishment 120. The driving condition management system 100 includes a vehicle display device 110, a computer 121, and the like.

[0013] The vehicle display device 110 is a so-called combination meter mounted on the vehicle 20, and is used in the driving condition management system 100 of the present disclosure. The vehicle display device 110 is arranged, for example, at a position on the dashboard corresponding to the driver's seat, or at a central position in the vehicle width direction of the dashboard. The vehicle display device 110 acquires various vehicle data from various vehicle ECUs 21 in various functional units that control, for example, "running," "turning," "stopping," and even "comfort" of the vehicle 20, and displays vehicle information corresponding to the vehicle data to the driver. The vehicle display device 110 has a meter ECU 111, a display unit 112, and the like.

[0014] In addition, the vehicle data obtained from the vehicle ECU 21 includes, for example, (1) vehicle speed, (2) road signs, (3) distance from the vehicle in front, (4) day / night discrimination, (5) lane departure, (6) lane sway, (7) destination guidance by the navigation system, (8) audio settings, (9) mileage, (10) engine RPMs (acceleration, deceleration), (11) pre-crash activation distance, (12) cruise control settings (distance from the vehicle in front), (13) head-up display settings, (14) occupant identification by an identification system (smart entry system, facial image recognition, etc.), (15) remaining fuel, (16) turn signals, (17) G sensor, (18) pedestrian detection, (19) eco-driving points, (20) date and time (year, month, day, time), etc.

[0015] The meter ECU 111 acquires the above-mentioned various vehicle data and displays the vehicle information to be displayed on the display unit 112. The meter ECU 111 corresponds to the control unit of the present disclosure.

[0016] A program is installed in the meter ECU 111 to acquire, calculate, and store, as operation data, vehicle data suitable for operation management (predetermined vehicle data) among various vehicle data. The program is installed, for example, in the vehicle dealer 11 by connecting (wired) an input terminal to a terminal of the meter ECU 111 (dotted dashed arrow in FIG. 1). For operation management, the meter ECU 111 utilizes, among the various vehicle data described above, vehicle data excluding, for example, (4), (8), (13), etc., that are not directly related to operation management.

[0017] By a program installed in the meter ECU 111, various vehicle data are linked to the driver identification data described above in (14) and compiled for each driver (individual) in a form that represents driving characteristics, such as average vehicle speed, number of times the speed limit was exceeded, number of times braking was applied, timing, etc., and then stored and transmitted to a computer 121 in the business facility 120 described below.

[0018] Also, the meter ECU 111 is connected (capable of communicating) with, for example, an Internet site set up by the vehicle manufacturer 10, so that the installed program for driving management can be updated or customized via communication. It is assumed that the installation of the program in the meter ECU 111 will also be performed using the Internet (communication) instead of an input terminal in the vehicle dealer 11.

[0019] The display unit 112 is a part that displays vehicle information (e.g., vehicle speed, engine RPM, remaining fuel, right / left turn instructions, mileage, fuel efficiency, and various warnings, etc.) from the meter ECU 111 to the driver. The display unit 112 is an image display unit that displays vehicle information using images such as a liquid crystal display or an organic EL display. Note that the display unit 112 may have a meter display unit using a pointer-type meter in addition to the image display unit described above.

[0020] Next, the computer 121 is a part that performs processing for operation management, and is installed in the business establishment 120. The computer 121 includes a communication unit 121a, a CPU 121b, a display unit 121c, and the like.

[0021] The communication unit 121a is a part that communicates with the meter ECU 111. The communication unit 121a is able to communicate with the vehicle manufacturer 10's site by acquiring access rights to the vehicle manufacturer 10's Internet site. Therefore, as described above, the vehicle manufacturer 10 and the meter ECU 111 can be connected via the Internet, and therefore the communication unit 121a is able to communicate with the meter ECU 111 via the Internet. The communication unit 121a is adapted to acquire operation data (vehicle data) from the meter ECU 111 (solid line arrow in FIG. 1). The communication unit 121a outputs the acquired operation data to the CPU 121b.

[0022] In addition, the communication unit 121a can transmit feedback information for the driver from the CPU 121b (described later) to the meter ECU 111 via the Internet (dashed arrow in FIG. 1). Based on this, the meter ECU 111 can display the feedback information on the display unit 112.

[0023] The CPU 121b is a calculation unit that analyzes the operation data acquired from the communication unit 121a, calculates data required for operation management (operation management data), and stores the calculation results. The operation management data includes, for example, the date and time when the driver gets on and off the vehicle, the traveling speed, the traveling time, the traveling distance, the passing points, the operating state of the vehicle 20, and the driving operation status represented by the traveling speed.

[0024] The CPU 121b also creates feedback information for the driver based on the operation management data. The feedback information is, for example, at least one of driving evaluation (safe driving, eco-driving, etc.), driving guidance (caution, warning, etc.), and treatment for the driver.

[0025] Furthermore, the CPU 121b learns the driver's reaction to the feedback information and adjusts the timing of displaying the feedback information or the display contents.

[0026] As an adjustment of the feedback information, for example, if a predetermined cumulative result of displaying the feedback information to the driver indicates that the driver's reaction to the driving operation tends to be slow, the CPU 121b advances the timing of displaying the feedback information. Alternatively, if the driver tends to react negatively to the display of the feedback information, the CPU 121b makes the content of the feedback information milder.

[0027] Furthermore, the CPU 121b is also capable of creating operation management data (operation management processing) using operation data that is a combination of a plurality of vehicle data items, such as those exemplified in (1) to (20) above.

[0028] For example, the CPU 121b creates operation management data using vehicle data such as a combination of (1) vehicle speed and (3) distance from the vehicle in front, or a combination of (1) vehicle speed and (2) road signs, or a combination of (1) vehicle speed and (7) destination guidance by a navigation system, or a combination of (16) turn signals and (17) G-sensor, or a combination of (1) vehicle speed, (2) road signs, and (18) pedestrian detection.

[0029] The above (1)+(3) can tell us whether the driver is tailgating or not, and the timing of braking to slow down. Also, (1)+(2) can tell us whether the driver is following the speed limit too fast or too slow, and whether the driver stops properly. Also, (1)+(7) can tell us whether the driver's approach speed to an intersection is appropriate. Also, (16)+(17) can tell us whether the timing of the turn instruction when changing lanes is appropriate. And, (1)+(2)+(18) can tell us whether the driver is detecting a pedestrian crossing and stopping for pedestrians is appropriate.

[0030] The vehicle operation management data may be generated by combining the above vehicle data in the meter ECU 111.

[0031] The display unit 121c is formed of, for example, a liquid crystal display or an organic EL display, and is a part that displays the traffic management data to the manager of the establishment 120.

[0032] The driving condition management system 100 of this embodiment is configured as described above. Hereinafter, the operation and effects of the system will be described.

[0033] In the driving condition management system 100 of this embodiment, the computer 121 (CPU 121b) of the business establishment 120 acquires driving data of the vehicle 20 from the meter ECU 111 of the vehicle display device 110. The CPU 121b analyzes the acquired driving data. The analysis results (driving management data) are displayed on the display unit 121c. The manager of the business establishment 120 can monitor the displayed contents and manage the driving status.

[0034] Furthermore, the CPU 121b displays feedback information for the driver on the display unit 112 of the vehicle display device 110 based on the analysis result of the operation data. The feedback information includes, for example, driving evaluation, driving guidance, and treatment for the driver.

[0035] As described above, in the driving status management system 100 of this embodiment, a program that acquires, calculates, and stores vehicle data as operation data is installed in the meter ECU 111 of the vehicle display device 110 that displays vehicle information using vehicle data, and the meter ECU 111 is capable of communicating with a computer 121 of a business establishment 120 that manages the operation of the vehicle 20, and the computer 121 performs processing for operation management using the operation data acquired from the meter ECU 111 through communication.

[0036] According to this embodiment, by reusing the vehicle display device 110, it is possible to form a driving status management system 100 with a simple configuration, without the need to set up dedicated equipment such as a digital tachograph for acquiring operational data, and without the need for connection to the vehicle 20 or installation space for the digital tachograph.

[0037] In addition, the vehicle display device 110 has a display unit 112 that displays vehicle information by images, and the computer 121 displays feedback information for the driver of the vehicle 20 on the display unit 112. This makes it possible to utilize the display unit 112 of the vehicle display device 110 to display feedback information to the driver in a timely and easy-to-view manner.

[0038] The feedback information includes at least one of driving evaluation, driving guidance, and allowances for the driver, which can lead to driving improvement for the driver and increased motivation of the driver.

[0039] In addition, the computer 121 learns the driver's reaction to the feedback information and adjusts the timing of displaying the feedback information or the display contents, thereby enabling effective feedback to be given to the driver's driving operation.

[0040] The vehicle data also includes identification data generated by an identification system that identifies the driver, and the meter ECU 111 associates the identification data with the vehicle data to generate operation data that identifies the driver. This saves the driver the trouble of inputting personal identification data and the start (time) of operation when boarding the vehicle. Furthermore, the operation data can be made to correspond to the driving characteristics of each individual, enabling effective operation management that includes feedback to the individual.

[0041] In addition, multiple types of vehicle data are provided, and the computer 121 performs processing for operation management using operation data that is a combination of multiple types of vehicle data. This allows the driver's driving conditions and driving characteristics to be widely understood, and the quality of operation management can be improved.

[0042] In addition, the traffic management program can be updated or customized via the Internet, etc. This reduces the complexity and costs associated with program maintenance.

[0044] In the above-described first embodiment, the display unit 112 of the vehicle display device 110 is used to display the feedback information, but this may be omitted. In other words, as a minimum function of the driving condition management system 100, the computer 121 may analyze the driving data and perform processing for driving management.

[0046] In addition, operational data may be utilized in combination with vehicle data as necessary.

[0047] Furthermore, updates or customization of the program for traffic management is not limited to being performed via communication. [Explanation of symbols]
