Abstract

A driving support device includes a sensor for acquiring object information on an object outside a vehicle; and a processing device for suppressing driving support, which is based on the object information, if an operation frequency of a wiper is equal to or higher than a predetermined reference and for providing the driving support if the operation frequency of the wiper is lower than the predetermined reference and if a vehicle speed is higher than a predetermined vehicle speed.

Claims

1. A driving support device comprising:

a sensor that acquires object information on an object outside a vehicle; and

a processing device that suppresses driving support, which is based on the object information, if an operation frequency of a wiper is equal to or higher than a predetermined reference and for providing the driving support if the operation frequency of the wiper is lower than the predetermined reference and if a vehicle speed is higher than a predetermined vehicle speed.

2. The driving support device according to claim 1, wherein processing of the processing device is executed in an auto mode in which the operation frequency of the wiper is automatically determined according to a detection value of a raindrop sensor and the vehicle speed.

3. The driving support device according to claim 2, wherein the operation frequency of the wiper in the auto mode is set lower than the predetermined reference if the vehicle speed is lower than the predetermined vehicle speed and is set according to the detection value of the raindrop sensor if the vehicle speed is higher than the predetermined vehicle speed.

4. The driving support device according to claim 1, wherein the processing device maintains a suppressed state of the driving support if the driving support is suppressed because the operation frequency of the wiper becomes equal to or higher than the predetermined threshold and, after that, if the operation frequency of the wiper becomes lower than the predetermined reference but if the vehicle speed is not higher than the predetermined vehicle speed.

5. A driving support device comprising:

a sensor that acquires object information on an object outside a vehicle;

a raindrop sensor that detects a raindrop amount adhered to a windshield; and

a processing device that suppresses driving support, which is based on the object information, if the raindrop amount is equal to or higher than a predetermined reference and for providing the driving support if the raindrop amount is lower than the predetermined reference and if a vehicle speed is higher than a predetermined vehicle speed.
