[0028]
Next, a vehicle operation management process executed by the vehicle operation management system having the above configuration will be described.
The vehicle operation management process is started when the data server 10 receives an instruction input (a request for driving analysis display or a request for form output) from the input device of the user terminal 20 via the network. Note that the instruction input also includes various data for specifying the target range (for example, the sales office or office to which the vehicle belongs, the identification information of the vehicle, the driving date and time, the type of dangerous driving to be detected, and the like). .
[0029]
When the vehicle operation management process is started, as shown in FIG. 4, first, in step S1, the data server 10 executes a process of acquiring travel data of the vehicle based on the instruction input (travel data acquisition step). .

[0030]
Subsequently, in step S2, a process of identifying a traveling route of the vehicle based on the traveling data of the vehicle acquired in step S1 and acquiring road traffic information and map information corresponding to the traveling route is executed (road traffic information).・ Map information acquisition step). Specifically, a traveling route of the vehicle is specified based on the position information (latitude / route) included in the traveling data, map information of a predetermined range including the traveling route, and each road / intersection on the traveling route.

Here, the dangerous driving includes, for example, sudden acceleration or sudden braking, excessive speed, forgetting to stop temporarily, suddenly changing lanes, insufficient deceleration at an intersection or in front of a curve, and the like. For example, when detecting excessive speed or insufficient deceleration, each dangerous driving is detected by comparing the vehicle speed included in the traveling data of each point with the regulated speed of the road corresponding to each point. In addition, when detecting sudden acceleration or sudden braking, a rate of change in the speed of the vehicle per unit time is obtained, and each dangerous driving is detected by determining whether or not the rate of change exceeds a set range. . When a sudden lane change is detected, a sudden lane change is detected by comparing a change in the traveling direction of the vehicle with road information (the direction of the road, the number of lanes). In addition, in the case of detecting forgetting to stop, it is determined whether or not the speed of the vehicle at the temporary stop position is lower than or equal to a predetermined speed, thereby detecting the forgetting to stop.

In addition, the sections in which the dangerous driving is detected in step S3 are displayed in a list, and by selecting any of the sections, the display is switched to the detailed display of the section.
For example, when a section in which sudden braking is detected is selected, the display is switched to a detailed display as shown in FIG. 6, and when a section in which excessive speed is detected is selected, the display is switched to a detailed display as shown in FIG. When the selected section is selected, the display is switched to the detailed display as shown in FIG. 6 to 8, the display of the map image is omitted.

In addition, the color of the object S corresponds to the speed of the vehicle, and the color of the road corresponds to the regulated speed of the road, and the color is set so that the color becomes darker as the speed increases. The display position of each object S corresponds to time, and the interval is set so as to correspond to a fixed time (for example, 0.5 to 1 sec). Therefore, the driving mode of the vehicle can be easily grasped only by looking at the display position, color, direction, and the like of the object S. Also, images (road signs and the like) related to road traffic information are displayed in the vicinity of each road, and by comparing these images and the colors of the roads with the display mode of the object S, according to the regulations and instructions related to road traffic. It can be easily grasped whether or not the vehicle has been traveling properly.
[0036]
6 to 8, P1, P2, and P3 represent the points of occurrence of dangerous driving, respectively. In the vicinity of each point P1, P2, and P3, the mode of dangerous driving, the date and time of occurrence, the location, and the vehicle Various information related to dangerous traveling such as speed or acceleration is displayed. In the example of FIG. 6, “sudden braking” of “8 km / h in 0.5 seconds” occurs at the point P1, and the date and time at that time are “May 15, 2002 13:46:23” and the place Is "Nihonbashi-Hakozakicho, Chuo-ku, Tokyo". Further, the example of FIG. 7 indicates that the vehicle travels at “58 km / h” at a point P2 where the maximum speed is regulated to “40 km / h”, and “excess speed” has occurred. . Further, the example in FIG. 8 indicates that the vehicle travels at “16 km / h” at the point P3 in the intersection, and “deceleration insufficient” has occurred. In this way, it is possible to easily understand when, where, and under what kind of situation a dangerous traveling has occurred.
[0037]
On the other hand, in step S6, form output data is generated based on the traveling data of the vehicle acquired in step S1, the road traffic information and the map information acquired in step S2, and the dangerous traveling information on dangerous traveling detected in step S3.

Next, in step S7, the form output data generated in step S6 is downloaded from the data server 10 to the user terminal 20, and a process of outputting the form from the printing device of the user terminal 20 is executed according to the form output data.
[0038]
As a result, a form as shown in FIG. 9 is output from the printing device of the user terminal 20, for example. This form includes basic information such as vehicle attribute information (driver, vehicle identification information, etc.), vehicle traveling date and time, traveling distance, speed graph / distribution, acceleration / deceleration graph / distribution, etc. Information on the occurrence of dangerous driving such as acceleration and sudden deceleration (date and time of occurrence, location, etc.) and evaluation information on such dangerous driving are posted. Therefore, according to this form, it is possible to not only grasp the dangerous driving but also grasp the driving tendency of the driver and diagnose the suitability. In addition, comparison between drivers, statistical analysis, and the like can be easily performed.
