Abstract

A driving support apparatus includes a controller. While the vehicle is driving, the controller is configured to obtain data indicating behavior of a body of a vehicle and output a certain sound based on information indicating stability of the behavior determined from the obtained data. Every time the vehicle drives a predetermined segment, the controller is configured to output a reward sound in accordance with the stability of the behavior in the predetermined segment.

First claim

The invention claimed is:

1. A driving support apparatus comprising:
sensors configured to obtain data indicating behavior of a body of a vehicle while the vehicle is traveling on a road, wherein the road is divided into segments based on a predetermined condition; and
a controller configured to:
determine that the vehicle enters from a first segment to a second segment subsequent to the first segment;
in response to determining that the vehicle enters the second segment, obtain the data from the sensors while the vehicle is traveling within the second segment;
determine that the vehicle enters from the second segment to a third segment subsequent to the second segment; and
in response to determining that the vehicle enters the third segment, (1) determine stability of the behavior of the vehicle based on the data obtained when the vehicle is traveling within the second segment, and (2) generate a reward sound based on the determined stability of the behavior of the vehicle in the second segment.

2. The driving support apparatus according to claim 1 , wherein, based on the determined stability of the behavior, the controller is further configured to control one or more of
a pitch of the reward sound,
a volume of the reward sound,
a type of the reward sound,
a tempo of the reward sound,
how many times the reward sound is output, and
a number of sound notes forming the reward sound.

3. The driving support apparatus according to claim 1 , wherein the controller is configured to determine the stability of the behavior by comparing a value representing the behavior in each segment with a threshold value.

4. The driving support apparatus according to claim 2 , wherein the controller is configured to determine the stability of the behavior by comparing a value representing the behavior in each segment with a threshold value.

5. The driving support apparatus according to claim 3 , wherein the controller is further configured to set the threshold value based on information related to a driving skill of a driver who drives the vehicle.

6. The driving support apparatus according to claim 4 , wherein the controller is further configured to set the threshold value based on information related to a driving skill of a driver who drives the vehicle.

7. The driving support apparatus according to claim 1 , wherein the controller is further configured to set one or more types of data to be used for determining the stability of the behavior based on information related to a driving skill of a driver who drives the vehicle.

8. The driving support apparatus according to claim 2 , wherein the controller is further configured to set one or more types of data to be used for determining the stability of the behavior based on information related to a driving skill of a driver who drives the vehicle.

9. The driving support apparatus according to claim 3 , wherein the controller is further configured to set one or more types of data to be used for determining the stability of the behavior based on information related to a driving skill of a driver who drives the vehicle.

10. The driving support apparatus according to claim 4 , wherein the controller is further configured to set one or more types of data to be used for determining the stability of the behavior, based on information related to a driving skill of a driver who drives the vehicle.

11. The driving support apparatus according to claim 5 , wherein the controller is further configured to set one or more types of data to be used for determining the stability of the behavior, based on information related to the driving skill of the driver.

12. The driving support apparatus according to claim 6 , wherein the controller is further configured to set one or more types of data to be used for determining the stability of the behavior, based on information related to the driving skill of the driver.

13. A driving support apparatus comprising:
sensors configured to obtain data indicating behavior of a body of a vehicle while the vehicle is traveling on a road, wherein the road is divided into segments based on a predetermined condition; and
circuitry configured to:
determine that the vehicle enters from a first segment to a second segment subsequent to the first segment;
in response to determining that the vehicle enters the second segment, obtain the data from the sensors while the vehicle is traveling within the second segment;
determine that the vehicle enters from the second segment to a third segment subsequent to the second segment; and
in response to determining that the vehicle enters the third segment, (1) determine stability of the behavior of the vehicle based on the data obtained when the vehicle is traveling within the second segment, and (2) generate a reward sound based on the determined stability of the behavior of the vehicle in the second segment.

14. The driving support apparatus according to claim 1 , wherein the controller is further configured to:
in response to determining that the vehicle enters the third segment, in addition to (1) determining stability of the behavior of the vehicle based on the data obtained when the vehicle is traveling within the current segment and (2) generating the reward sound based on the determined stability of the behavior of the vehicle in the second segment, (3) obtain the data from the sensors while the vehicle is traveling within the third segment; and
determine that the vehicle enters from the third segment to a fourth segment subsequent to the third segment; and
in response to determining that the vehicle enters the fourth segment, (1) determine stability of the behavior of the vehicle based on the data obtained when the vehicle is traveling within the third segment, and (2) generate a reward sound based on the determined stability of the behavior of the vehicle in the third segment.

15. The driving support apparatus according to claim 1 , wherein the controller is further configured to:
receive information related to a driving skill of a driver who drives the vehicle; and
set a threshold value such that the higher the driving skill of the driver is, the lower the threshold value is set.

16. The driving support apparatus according to claim 15 , wherein the higher the driving skill of the driver is, the more types of data the controller is configured to set.

17. The driving support apparatus according to claim 13 , wherein the circuitry is further configured to:
in response to determining that the vehicle enters the third segment, in addition to (1) determining stability of the behavior of the vehicle based on the data obtained when the vehicle is traveling within the current segment and (2) generating the reward sound based on the determined stability of the behavior of the vehicle in the second segment, (3) obtain the data from the sensors while the vehicle is traveling within the third segment; and
determine that the vehicle enters from the third segment to a fourth segment subsequent to the third segment; and
in response to determining that the vehicle enters the fourth segment, (1) determine stability of the behavior of the vehicle based on the data obtained when the vehicle is traveling within the third segment, and (2) generate a reward sound based on the determined stability of the behavior of the vehicle in the third segment.
