Abstract
A raindrop detecting device for detecting a raindrop amount on a windshield of a vehicle and selecting a wiping mode of a wiper based on the detected raindrop amount includes a controller for lowering the wiping mode when the detected raindrop amount is kept to be smaller than a mode-keep threshold while the wiper performs a predetermined number of wiping operations. The controller changes the predetermined number of wiping operations based on at least one of a sensitivity data of a user of the vehicle and a rainfall block data relative to the vehicle.
Claims12
A raindrop detecting device for detecting a raindrop amount on a windshield of a vehicle and selecting a wiping mode of a wiper based on the detected raindrop amount, the device comprising:
- a controller for lowering the wiping mode when the detected raindrop amount is kept to be smaller than a mode-keep threshold while the wiper performs a predetermined number of wiping operations, wherein
- the controller changes the predetermined number of wiping operations based on at least one of a sensitivity data of a user of the vehicle and a rainfall block data relative to the vehicle.
A raindrop detecting device for detecting a raindrop amount on a windshield of a vehicle and selecting a wiping mode of a wiper based on the detected raindrop amount, the device comprising:
- a controller for calculating an average of a predetermined number of the detected raindrop amounts, and lowering the wiping mode when the average is smaller than a mode-keep threshold, wherein
- the controller changes the predetermined number of the detected raindrop amounts based on a sensitivity data of a user of the vehicle and a rainfall block data relative to the vehicle.
A method of selecting a wiping mode of a wiper for a vehicle, the method comprising:
- detecting a raindrop amount on a windshield of the vehicle;
- lowering the wiping mode when the detected raindrop amount is kept to be smaller than a mode-keep threshold while the wiper performs a predetermined number of wiping operations;
- and
- changing the predetermined number of wiping operations based on at least one of a sensitivity data of a user of the vehicle and a rainfall block data relative to the vehicle.
