Abstract

Driving assistance systems, methods, and programs for a vehicle, acquire a travel history of a vehicle, acquire a guidance target point at which a guidance target event has occurred based on the travel history, and acquire a tendency of a driving operation of a driver of the vehicle based on the travel history. The systems, methods, and programs determine whether to provide guidance on the guidance target point based on the tendency of the driving operation, and provide guidance relating to the guidance target point for which it is determined to provide the guidance.

Claims

1. A driving assistance system for a vehicle, the system comprising:

a processor programmed to;

acquire a travel history of a vehicle;

acquire a guidance target point at which a guidance target event has occurred based on the travel history;

acquire a tendency of a driving operation of a driver of the vehicle based on the travel history;

determine whether to provide guidance on the guidance target point based on the tendency of the driving operation; and

provide guidance relating to the guidance target point for which it is determined to provide the guidance.

2. The driving assistance system according to claim 1, wherein the processor is programmed to:

a plurality of guidance target points existing in an area of a predetermined distance;

acquire an index indicating the tendency of the driving operation of the driver of the vehicle for each of the plurality of the guidance target points; and

determine whether to provide the guidance on the guidance target point based on a sum of the index of each of the plurality of the guidance target points.

3. The driving assistance system according to claim 1, wherein the processor is programmed to:

acquire a tendency of a driving technique of the driver of the vehicle as the tendency of the driving operation; and

increase a probability at which it is determined to provide the guidance on the guidance target point as the tendency of the driving technique is higher.

4. The driving assistance system according to claim 3, wherein the processor is programmed to:

acquire the tendency of the driving technique based on an occurrence frequency of the driving operation of which an operation amount per reference unit is equal to or greater than a threshold value.

5. The driving assistance system according claim 1, wherein the processor is programmed to:

acquire a surrounding condition of the vehicle; and

determine whether to provide the guidance on the guidance target point based on the tendency of the driving operation and the surrounding condition.

6. The driving assistance system according to claim 5, wherein the processor is programmed to:

acquire a traffic condition of a road traveled by the vehicle as the surrounding condition; and

increase a probability at which it is determined to provide the guidance on the guidance target point as the traffic condition is a condition easier to travel on the road.

7. The driving assistance system according to claim 5, wherein the processor is programmed to:

acquire weather of surrounding of the vehicle as the surrounding condition; and

increase a probability at which it is determined to provide the guidance on the guidance target point as the weather is better.

8. A driving assistance method for a vehicle, the method comprising:

acquiring a travel history of a vehicle;

acquiring a guidance target point at which a guidance target event has occurred based on the travel history;

acquiring a tendency of a driving operation of a driver of the vehicle based on the travel history;

determining whether to provide guidance on the guidance target point based on the tendency of the driving operation; and

providing guidance relating to the guidance target point for which it is determined to provide the guidance.

9. A computer-readable storage medium storing a computer-executable driving assistance program fir a vehicle, the program causing a computer to execute the following instructions:

acquiring a travel history of a vehicle;

acquiring a guidance target point at which a guidance target event has occurred based on the travel history;

acquiring a tendency of a driving operation of a driver of the vehicle based on the travel history; and

determining whether to provide guidance on the guidance target point based on the tendency of the driving operation; and

providing guidance relating to the guidance target point for which it is determined to provide the guidance.
