Abstract

An evaluation apparatus ( 10 ) includes an acquisition unit ( 110 ), a determination unit ( 120 ), and an evaluation unit ( 130 ). The acquisition unit ( 110 ) acquires detection information indicating a result of detecting a periphery of a vehicle by a sensor, and travel information of the vehicle. The determination unit ( 120 ) determines, by using the detection information, whether there is a possibility of collision between the vehicle and another object. The evaluation unit ( 130 ) determines, by using the travel information at a time when the possibility of collision is detected by the determination unit ( 120 ), whether a driver of the vehicle has performed an operation for reducing the possibility of collision, and evaluates the driver based on a result of the determination.

Claims (60)

1 . An evaluation apparatus, comprising:

at least one memory configured to store instructions; and

at least one processor configured to execute the instructions to:

acquire detection information indicating a result of detecting a periphery of a vehicle by a sensor, and travel information of the vehicle;

determine, by using the detection information, timing when there is a possibility of collision between the vehicle and another object; and

determine, by using the travel information corresponding to the timing determined, whether a driver of the vehicle has performed an operation for reducing the possibility of collision; and

decrease an evaluation of the driver in a case where it is determined that the driver of the vehicle has not performed the operation for reducing the possibility of collision.

2 . The evaluation apparatus according to claim 1 , wherein

the at least one processor is further configured to execute the instructions to

determine whether there is the possibility of collision by further using the travel information.

3 . The evaluation apparatus according to claim 1 , wherein

the at least one processor is further configured to execute the instructions to

generate the result of determination by further using the detection information.

4 . The evaluation apparatus according to claim 1 , wherein

the travel information includes route guidance information provided to the vehicle.

5 . The evaluation apparatus according to claim 1 , wherein

the at least one processor is further configured to execute the instructions to:

acquire, in association with the detection information and the travel information, position information indicating a position of the vehicle; and

store, in a storage unit, a position of the vehicle corresponding to the timing determined.

6 . The evaluation apparatus according to claim 1 , wherein

the another object is at least one of a pedestrian, a bicycle, and a motorcycle.

7 . The evaluation apparatus according to claim 1 , wherein

the detection information includes a position and a moving direction of the another object.

8 . The evaluation apparatus according to claim 1 , wherein

the detection information includes a type of at least one of a road surface marking and a traffic sign.

9 . The evaluation apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

decrease the evaluation in real time; and

transmit the evaluation to a communication apparatus of the vehicle and cause the communication apparatus to output information indicating the evaluation to an output apparatus of the vehicle.

10 . The evaluation apparatus according to claim 9 , wherein the output apparatus of the vehicle comprises at least one: of a display inside the vehicle, a portable terminal brought into the vehicle, or a light emission apparatus inside the vehicle.

11 . The evaluation apparatus according to claim 10 , wherein the at least one processor is further configured to execute the instructions to:

control, according to the evaluation result, the light emission apparatus to change at least one of a light emission color and a light emission pattern.

12 . The evaluation apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

store, in a storage apparatus, evaluations respectively corresponding to each of a plurality of drivers, the evaluations being respectively associated with identification information of each driver and a vehicle location where each of the evaluations were obtained; and

determine and output a location where a collision between the vehicle and another object may occur by executing statistical processing of the evaluations stored in the storage apparatus.

13 . The evaluation apparatus according to claim 12 , wherein the at least one processor is further configured to execute the instructions to:

read, upon receiving identification information from a terminal of a driver of the plurality of drivers, information associated with the identification information from the storage apparatus; and

transmit the information read to the terminal,

wherein the information comprises: a location where the evaluation is executed, an evaluation result of the evaluation, and an image used at a time when the evaluation is executed.

14 . The evaluation apparatus according to claim 13 , wherein the at least one processor is further configured to execute the instructions to:

aggregate, for each piece of the identification information, at least one of a condition that has resulted in a low evaluation result and a condition that has resulted in a high evaluation result;

transmit a result of the aggregation to a terminal of the driver,

wherein the condition is information indicating a traffic rule at a location of evaluation, the information comprising a specific traffic sign, a road surface marking, and/or meanings thereof.

15 . The evaluation apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

increase an evaluation of the driver in a case where it is determined that the driver of the vehicle has performed the operation for reducing the possibility of collision.

16 . An evaluation method comprising,

by at least one processor:

acquiring detection information indicating a result of detecting a periphery of a vehicle by a sensor, and travel information of the vehicle;

determining, by using the detection information, timing when there is a possibility of collision between the vehicle and another object; and

determining, by using the travel information corresponding to the timing determined, whether a driver of the vehicle has performed an operation for reducing the possibility of collision;

decreasing an evaluation of the driver in a case where it is determined that the driver of the vehicle has not performed the operation for reducing the possibility of collision;

controlling, according to the evaluation, a light emission apparatus inside the vehicle to change at least one of a light emission color or a light emission pattern.

17 . The evaluation method of claim 16 , further comprising,

increasing an evaluation of the driver in a case where it is determined that the driver of the vehicle has performed the operation for reducing the possibility of collision.

18 . A non-transitory computer-readable storage medium storing a program that is configured to cause at least one processor to perform:

acquiring detection information indicating a result of detecting a periphery of a vehicle by a sensor, and travel information of the vehicle;

determining, by using the detection information, timing when there is a possibility of collision between the vehicle and another object; and

determining, by using the travel information corresponding to the timing determined, whether a driver of the vehicle has performed an operation for reducing the possibility of collision, and

decreasing an evaluation of the driver in a case where it is determined that the driver of the vehicle has not performed the operation for reducing the possibility of collision.

19 . The non-transitory computer-readable storage medium of claim 18 , wherein the program is further configured to cause the at least one processor to perform:

increasing an evaluation of the driver in a case where it is determined that the driver of the vehicle has performed the operation for reducing the possibility of collision.
