Abstract
A sensor cleaning control device and method are based on recognition of surrounding objects around a vehicle. The control device and method are applied to a vehicle and consider an object recognized in scattering areas where contamination occurs due to a fluid sprayed from a nozzle to clean blockages or contamination on sensing portion covers provided at sensors, perform cleaning delay using the washer fluid through nozzle delay spraying by a controller, perform air cleaning not using the washer liquid through nozzle air spraying, and do not perform the cleaning through nozzle non-spraying due to replacement of data of other sensor so that the contamination of the object that is contaminated due to the sensor cleaning is reduced or prevented.
Claims12
A sensor cleaning control device based on recognition of an external object around a vehicle, the sensor cleaning control device comprising:
- one or more sensors configured to detect an external object of a vehicle, a surrounding environment, or a vehicle status;
- a sensing portion cover provided on each of the one or more sensors;
- a nozzle configured to spray a fluid;
- and
- a controller configured to, when a blockage is detected on the sensing portion cover, recognize the external object and perform cleaning control for the blockage according to the external object before cleaning is performed on the blockage using the fluid,
- wherein the controller is configured to determine a fluid scattering area and whether the external object within the fluid scattering area is detected by a sensor other than a sensor where the blockage is detected on the sensing portion cover and is configured to determine whether to perform the cleaning or cleaning delay, and
- wherein the cleaning delay is performed by using the fluid through nozzle spraying delay when a speed of the vehicle is reduced or by using air through nozzle air spraying when the speed of the vehicle cannot be reduced.
A sensor cleaning control method based on recognition of surrounding objects around a vehicle, the sensor cleaning control method comprising:
- detecting, by a controller, a blockage on a sensing portion cover provided on a sensor;
- determining a necessity for cleaning in order to remove the blockage;
- and
- controlling a cleaning delay of a sensor cleaning system when an external object is detected in a fluid scattering area of the sensor cleaning system,
- wherein the controller is configured to determine the fluid scattering area and whether the external object within the fluid scattering area is detected by a sensor other than a sensor where the blockage is detected on the sensing portion cover and is configured to determine whether to perform the cleaning or the cleaning delay, and
- wherein the cleaning delay is performed by using a fluid through nozzle spraying delay when a speed of the vehicle is reduced or by using air through nozzle air spraying when the speed of the vehicle cannot be reduced.
