  The steering angle sensor 351 is a sensor for detecting the steering angle of the steering included in the vehicle 300. A detection result of the steering angle sensor 351 can be used to detect a so-called sudden handle or the like that is generally evaluated as a bad driving operation. The accelerator opening sensor 352 is a sensor for detecting the amount of depression of the accelerator pedal (accelerator opening) of the vehicle 300. In normal travel, as the accelerator opening increases, the amount of fuel supplied to the engine of the vehicle 300 increases and the acceleration of the vehicle 300 increases. The detection result of the accelerator opening sensor 352 can be used to detect so-called sudden start or sudden acceleration, which is generally evaluated as a bad driving operation.

  The brake depression degree sensor 353 is a sensor for detecting the amount of depression of the brake pedal of the vehicle 300 (brake depression degree). In normal travel, the braking force of the vehicle 300 increases as the degree of brake depression increases. The detection result of the brake depression degree sensor 353 can be used to detect so-called sudden braking, which is generally evaluated as a bad driving operation.

  The driving operation evaluation unit 120 evaluates the driving operation related to the driver of the vehicle 300 based on the time series data stored in the driver current model DB 210. Here, the driving operation evaluation method by the driving operation evaluation unit 120 may be performed based on the number of sudden braking, the number of sudden starts, and the number of sudden steering. As the number of these driving operations increases, the evaluation of the driving operation decreases.

  Further, the driving operation evaluation method by the driving operation evaluation unit 120 may be a mode in which the operation data recorded in the driver current model DB 210 and the operation data recorded in the driving norm model DB 220 are compared and evaluated. The driving operation can be evaluated based on the difference between the operation data related to the actual driving operation and the operation data related to the exemplary driving operation.

  In addition, the mark display means 170 displays a mark (operation mark) indicating a time point corresponding to the vehicle position indicated on the map on the time-series data displayed by the model operation display means 160. For example, the mark display means 170 displays an operation mark as shown in FIG. Then, the two marks (the own vehicle mark and the operation mark) displayed by the mark display means 170 move on the map and the graph as time passes. By doing so, it is possible to make the driver easily understand the appropriate operation amount at a specific place for the device related to the driving operation.

That is, the device image display means 180 displays a moving image (for example, showing a state where the brake pedal is greatly depressed) according to the operation amount of each device. For example, the device image display hand 180 displays on the display device 371 an image in which the brake pedal is greatly depressed when the brake pedal is largely depressed.

  The device image display unit 180 displays the image of the device in conjunction with the position or time point indicated by the mark (the vehicle mark or the operation mark) displayed by the mark display unit 170. Further, the device image display unit 180 displays the image of the device in parallel with the time series graph displayed by the driver operation display unit 150 and the model operation display unit 160 (related to each device shown in FIGS. 2 and 3). See image). In this way, the driver can be more easily informed of the difference between the model device operation amount and the actual operation amount.

  The warning notification unit 190 outputs a warning sound from the speaker 372 based on the operation data of the driver. Specifically, the warning notification unit 190 outputs a warning sound when the driver's operation data exceeds a certain threshold value. For example, the warning notification unit 190 outputs a warning sound when the driver suddenly turns off the steering wheel, sudden braking, sudden start, or the like. The warning notification unit 190 may be configured to notify a plurality of warning sounds properly according to the device related to the operation data. For example, it is conceivable to use different warning sounds for sudden steering, sudden braking, and sudden acceleration. By doing so, it is possible to effectively teach the driver about the problems related to the actual driving operation.

  The advice display unit 200 displays advice related to the driving operation in parallel with the time series graph displayed by the driver operation display unit 150 and the exemplary operation display unit 160. The advice display unit 200 displays various advices according to the driving environment at the position indicated by the mark or the time point as the mark (the vehicle mark or the operation mark) displayed by the mark display unit 170 moves. By doing so, it is possible to appropriately present advice relating to the driving operation according to the driving environment.

  Here, the driving operation evaluation device 100 may be configured such that each of the above units performs processing only when the evaluation by the driving operation evaluation unit 120 is low. By doing so, it is possible to easily compare and present the operation state of the driver and the exemplary operation state in a place where the evaluation of the driving operation is low, and it is possible to further improve the teaching effect for the driver.

  Below, the flow of a process of the driving operation evaluation apparatus 100 is demonstrated. First, processing while the driver is performing a normal driving operation will be described.
