[0011] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0012] The driver evaluation system 1 of this embodiment is a system for evaluating drivers who drive trucks 10 that deliver packages. As shown in the figure, the driver evaluation system 1 includes a device (on-board device) 2 mounted on the truck 10, which is an example of a vehicle, a server 3 (driver evaluation device) that can communicate with the device 2 via an internet communication network 11, and a terminal 4 that can communicate with the server 3 via the internet communication network 11.
[0013] 2, the device 2 includes an internet communication unit 21, a GPS communication unit 22, an external connection terminal 23, a CAN interface (I / F) 24, and a control unit 25. The internet communication unit 21 is composed of a circuit, an antenna, and the like for connecting to the internet communication network 11. As is well known, the GPS communication unit 22 receives radio waves emitted from a plurality of GPS (Global Positioning System) satellites, determines the current position, and outputs the position to the control unit 25 (described later). External devices such as a display unit 30 and a speaker 40 are connected to the external connection terminal 23. The display unit 30 displays warnings and the like for the driver. The speaker 40 outputs warning sounds and the like for the driver.
[0014] The CAN interface (I / F) 24 is provided for connection to a CAN (Controller Area Network) bus in the vehicle. The device 2 can acquire the speed, G-value (acceleration), and engine speed of the truck 10 from the CAN by performing CAN communication. Note that, in this embodiment, an example will be described in which the device 2 acquires the speed and G-value (acceleration) of the truck 10 through CAN communication, but this is not limiting. The device 2 may utilize GPS information (current position, time) acquired from the GPS communication unit 22, and the control unit 25 of the device 2 may convert the GPS information to acquire the speed and G-value (acceleration) of the truck 10. Furthermore, the G-value may be acquired from a built-in G-sensor in the device 2.
[0015] The control unit 25 includes memories such as RAM (Random Access Memory) and ROM (Read Only Memory), is configured with a CPU (Central Processing Unit) that operates according to a program, and is responsible for overall control of the device 2. The control unit 25 periodically obtains the current position from the GPS communication unit 22 and transmits it to the server 3. The control unit 25 also periodically obtains the speed, G value, and engine RPM from the CANI / F 24 and transmits them to the server 3.
[0016] As shown in FIG. 3, the server 3 includes an internet communication unit 31, a database (DB) 32, and a control unit 33.
[0017] The internet communication unit 31 is composed of a circuit for connecting to the internet communication network 11. The DB 32 records the history of location information, speed, G-value, engine RPM, etc., periodically transmitted from the vehicle-mounted device 2. The control unit 33 is equipped with memories such as RAM and ROM, is composed of a CPU that operates according to a program, and controls the entire server 3.
[0018] The terminal 4 is configured by, for example, a PC or a smartphone, and communicates with the server 3 via the internet communication network 11. The terminal 4 is a terminal owned by the delivery company.
[0019] Next, the operation of the driver evaluation system 1 configured as described above will be described with reference to Fig. 4. First, the control unit 25 of the device 2 (hereinafter simply referred to as "device 2") periodically acquires the current position, speed, G value, and engine RPM (operation data) from the GPS communication unit 22 and the CANI / F 24 (S1). While driving (N in S2), the device 2 repeatedly collects the operation data (S1).
[0020] When the operation ends (Y in S2), the device 2 functions as a transmitter and transmits the operation data collected during one operation to the server 3 (S3), and ends the processing. In this embodiment, an example is described in which the device 2 transmits operation data to the server 3 every time one operation ends, but this is not limiting and the device 2 may also transmit operation data to the server 3 at regular intervals. The control unit 33 of the server 3 (hereinafter simply abbreviated as "server 3") receives the operation data from the device 2 (S4) and stores it in the DB 32. The server 3 stores the operation data in the DB 32 so that the driver can be identified, for example by including a driver ID in the operation data.
[0021] One possible method for the server 3 to acquire the driver ID is for the server 3 to acquire the driver ID corresponding to the vehicle ID included in the operation data from operation plan information that indicates which driver is in which vehicle. Alternatively, the driver may insert a memory card with the driver ID written to the device 2 every time the driver drives, and the device 2 may read the driver ID from the memory card and include it in the operation data and transmit it to the server 3. Since the server 3 receives operation data from the devices 2 mounted on each of the multiple trucks 10, the DB 32 stores operation data for multiple drivers.
[0022] Next, for example, a manager of the delivery company operates terminal 4 to send a driver evaluation request to server 3 (S8). The evaluation request includes the driver ID for which evaluation is requested. Upon receiving the evaluation request (S5), server 3 calculates evaluation values for multiple evaluation items for each driver for whom evaluation was requested, based on driving data acquired during multiple trips (S6).
[0023] A specific example of S6 will be described. In this embodiment, the server 3 calculates the evaluation values of the evaluation items of safety and punctuality, for example, based on operation data acquired every month. For the evaluation item of safety, the server 3 calculates the frequency of speeding (the distance traveled in km per speeding incident in one month) based on the speed and current location acquired over the course of one month. For example, if the frequency of speeding is 120 km, it means that the speeding incident occurred once every 120 km traveled.
[0024] For the evaluation item of punctuality, which indicates whether the vehicle arrived at the destination at the scheduled time, the server 3 calculates the average speed from the departure point to the destination along a specified route based on the speed and current location acquired over a one-month period.
[0025] Next, the server 3 functions as a providing unit, creates a graph in which the calculated evaluation values for each driver are plotted on a graph with multiple types of evaluation items as axes, and transmits the created graph to the terminal 4 (S7). A specific example of S7 will be described. In this embodiment, as shown in Figures 5 and 6, the server 3 creates a graph in which the frequency of speeding accidents calculated in S6 for each of drivers A to D and the average speed from the departure point to the destination on a predetermined route are plotted on a graph with safety on the vertical axis and punctuality on the horizontal axis.
[0026] The server 3 also divides the graph into multiple regions and creates a graph that allows the driver's characteristics to be identified for each region. In this embodiment, the driver's characteristics are divided into four types: "careful," "bold," "hard worker," and "mischievous." "Careful" refers to a type that prioritizes safe driving too much and tends to be late, so the server 3 creates a graph in which "careful" is displayed in the region above the horizontal axis and to the left of the vertical axis. "Bold" refers to a type that disregards both safe driving and being punctual, so the server 3 creates a graph in which "bold" is displayed in the region below the horizontal axis and to the left of the vertical axis.
[0027] A "hard worker" is a type of driver who values both safe driving and punctuality, and will drive safely and deliver on time even at the expense of their own rest time. The server 3 creates a graph in which "hard worker" is displayed in the area above the horizontal axis and to the right of the vertical axis. A "disorganized" is a type of driver who values punctuality more than safe driving, and the server 3 creates a graph in which "disorganized" is displayed in the area below the horizontal axis and to the right of the vertical axis. The server 3 also creates a graph in which the area of ideal punctuality can be clearly displayed, as shown by the dotted line in Figure 3.
[0028] Furthermore, the server 3 creates a graph so that the history for each month can be seen, as shown in FIGS. 5 and 6, and transmits the created graph to the terminal 4 (S7).
[0029] When the terminal 4 receives the graph from the server 3 (S9), it displays the received graph (S10) and carries out the processing. The manager of the delivery company can see at a glance the graphs shown in Figures 5 and 6 displayed on the terminal 4 and understand what characteristics (qualities) the drivers A to D have.
[0030] According to the above-described embodiment, the server 3 calculates an evaluation value for each driver's driving data evaluation items (safety and punctuality) based on driving data acquired during multiple trips, and provides a graph in which the calculated evaluation values are plotted on a graph with safety and punctuality as the axes. Furthermore, the server 3 divides the graph into multiple regions, and provides a graph in which the driver's characteristics ("careful," "bold," "hardworking," "mischievous") for each region can be identified.
[0031] This makes it possible to provide a graph that shows the characteristics (qualities) of drivers A to D at a glance based on driving data obtained during multiple trips, i.e., over a long period of time, making it possible to identify the characteristics of drivers A to D and make an appropriate evaluation.
[0032] According to the embodiment described above, the evaluation items include safety and punctuality, which allows the characteristics of a delivery company driver to be identified.
[0033] According to the above-described embodiment, the server 3 calculates the frequency of speeding as an evaluation value for safety, and calculates the average speed from the departure point to the destination along a predetermined route as an evaluation value for punctuality, thereby enabling the safety and punctuality to be evaluated with high accuracy.
[0034] According to the above-described embodiment, by displaying the dotted line indicating the ideal region for punctuality, it becomes even easier to identify the characteristics of the driver.
[0035] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.
[0036] According to the above-described embodiment, the regions are displayed so as to be distinguishable by the vertical and horizontal axes as shown in Figures 5 and 6, but this is not limiting. As shown in Figure 7, each region may be displayed so as to be distinguishable by displaying dotted lines or the like at the boundaries between regions or by using different colors for each region.
[0037] According to the above-described embodiment, a graph with two axes representing safety and punctuality is displayed, but this is not limiting. For example, a three-axis graph with an additional axis representing transportation quality may be displayed.
[0038] According to the above-described embodiment, the average speed on the same route is used as the evaluation value of punctuality, but this is not limiting. For example, the server 3 may calculate, as the evaluation value of punctuality, the frequency with which the deviation distance between the predetermined delivery route and the current location of the truck 10 exceeds the deviation warning distance over a one-month period. The server 3 may also calculate, as the evaluation value of punctuality, the frequency with which the driver's driving time is not within a predetermined travel time (e.g., 15:00-6:00) over a one-month period. The server 3 may also calculate, as the evaluation value of punctuality, the frequency with which the rest time during one trip exceeds the stop warning time over a one-month period. The server 3 may also calculate, as the evaluation value of punctuality, the average delay time of the arrival time at a delivery location, a destination, or the like over a one-month period.
[0039] In the above-described embodiment, the frequency of speeding is used as the safety evaluation value, but the present invention is not limited to this. The server 3 may calculate the frequency of dangerous driving as the safety evaluation value, and may calculate, for example, the frequency of sudden deceleration, sudden acceleration, sharp turns, and drinking as the safety evaluation value.
[0040] Furthermore, in the above-described embodiment, the evaluation items are safety and punctuality, but are not limited to these. The evaluation items may also include the quality and economy of transportation. The server 3 may calculate the frequency of sudden deceleration, sudden acceleration, sharp turns, and impacts as the evaluation value of transportation quality. The server 3 may also calculate the shipper's evaluation of the loading condition (dangerous, normal, careful, etc.), the consignee's evaluation of the condition of the received luggage (dangerous, normal, careful, etc.), and the consignee's evaluation of the number of luggage (as ordered, below order, etc.) as the evaluation value of transportation quality.
[0041] The server 3 may also calculate fuel efficiency calculated from the engine speed and speed, or the frequency of sudden deceleration, sudden acceleration, and impact as an evaluation value of economic efficiency.
