Abstract

A driving support apparatus includes a controller. The controller is configured to obtain data indicating behavior of a body of a vehicle while the vehicle is driving. The controller is configured to continuously output a sound that is to be changed in accordance with the behavior while the vehicle is driving. The controller is configured to set a predetermined threshold for a value indicating magnitude of the behavior, based on a driving condition of the vehicle. The controller is configured to change the sound in accordance with the value indicating the magnitude of the behavior in a case where the value indicating the magnitude of the behavior is smaller than the predetermined threshold. The controller is configured to execute predetermined control in a case where the value indicating the magnitude of the behavior is greater than or equal to the predetermined threshold.

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, wherein the data include acceleration of the vehicle; and
a controller configured to:
convert the data from the sensors into an evaluation value;
generate sound data representing sounds that convey consecutive change in the evaluation value in response to a real-time change in the behavior of the body of the vehicle;
control a sound device, disposed inside the vehicle, based on the sound data to output the sounds to allow the driver to know the change in the behavior of the body of the vehicle in real time;
set a threshold that is variable based on a condition surrounding the vehicle and a driving skill of a driver of the vehicle; and
execute predetermined control of the sound device when a magnitude of the evaluation value is greater than or equal to the threshold.

2. The driving support apparatus according to claim 1 , wherein the controller is configured to sequentially change the sound in accordance with a change in the evaluation value indicating the real-time changes in the magnitude of the behavior in the case where the value indicating the magnitude of the behavior is smaller than the predetermined threshold.

3. The driving support apparatus according to claim 1 , wherein the controller is configured to set the threshold to be a smaller value as the driving skill of the driver is higher.

4. The driving support apparatus according to claim 2 , wherein the controller is configured to set the threshold to be a smaller value as the driving skill of the driver is higher.

5. The driving support apparatus according to claim 1 , wherein the controller is configured to set the threshold based on the condition surrounding the vehicle which influences stability of the behavior of the body of the vehicle.

6. The driving support apparatus according to claim 2 , wherein the controller is configured to set the predetermined threshold based on the condition surrounding the vehicle which influences stability of the behavior of the body of the vehicle.

7. A driving support apparatus comprising:
sensors configured to obtain data indicating behavior of a body of the vehicle while the vehicle is traveling, wherein the data include acceleration of the vehicle; and
circuitry configured to:
convert the data from the sensors into an evaluation value;
generate sound data representing sounds that conveys consecutive change in the evaluation value in response to a real-time change in the behavior of the body of the vehicle;
control a sound device, disposed inside the vehicle, based on the sound data to output the sound to allow the driver to know the change in the behavior of the body of the vehicle in real time;
set a threshold that is variable based on a condition surrounding the vehicle and a driving skill of a driver of the vehicle; and
execute predetermined control of the sound device when a magnitude of the evaluation value is greater than or equal to the threshold.
