US20130093364 for example discloses a system for varying the speed of the windshield wipers by e.g. measuring the speed of the vehicle and adapting the speed of the windshield wipers to the speed of the vehicle.
OBJECTS OF THE INVENTION An object of the present invention is to provide a method for controlling the windshield wiper unit of a vehicle which improves the adaptability of the windshield wiper unit.
Another object of the present invention is to provide a system for controlling the windshield wiper unit of a vehicle which improves the adaptability of the windshield wiper unit.
SUMMARY OF THE INVENTION These and other objects, apparent from the following description, are achieved by a method, a system, a vehicle, a computer program and a computer program product, as set out in the appended independent claims. Preferred embodiments of the method and the system are defined in appended dependent claims.
Specifically an object of the invention is achieved by a method for controlling the windshield wiper unit of a vehicle. The method comprises the step of determining a potential risk for staining of water by means of said wiper unit upon road users present in the surroundings of said vehicle. The method comprises the step of automatically reducing the wiping speed of said wiper unit based on the determined potential risk. Hereby road users such as passengers entering a bus will not be stained by water as the windshield wiper unit adapts its wiping speed so as to avoid that. Thus the adaptability of the windshield wiper unit is hereby improved.
According to an embodiment of the method the step of reducing said wiping speed is effected when the vehicle comes to a standstill. Hereby staining is avoided maintaining safety as the windshield wiper unit will operate at the necessary speed when the vehicle is moving thus not negatively affecting the visibility for the driver.
According to an embodiment of the method the step of reducing the wiping speed comprises reducing said wiping speed to zero. Hereby is secured that no road users present in the surroundings of the vehicle will be stained due to operation of the windshield wiper unit.
According to an embodiment of the method the step of determining a potential risk for staining comprises the step of determining whether a front entrance door is opened or is determined to be opened within a predetermined time Hereby unnecessary reduction of speed of the windshield wiper unit may be avoided.
According to an embodiment the method comprises the step of determining a potential risk for staining comprises the step of determining the presence of a road user in the surroundings of said vehicle. Hereby it is secured that a road user present in the surroundings of the vehicle will not be stained by means of the windshield wipers of the vehicle.
According to an embodiment the method comprises the step of resetting the wiping speed of the windshield wiper unit if it is determined that there is no longer a risk for staining. Hereby normal operation of the windshield wiper unit will be optimized such that visibility of the driver will be maintained when there is no risk for staining.
According to an embodiment the method comprises the steps of: determining whether the vehicle is taking off or is determined to take off; and, based on a determined taking off of the vehicle, resetting the wiping speed of the windshield wiper unit. Hereby is secured that the visibility of the driver is not impaired during take off.
Specifically an object of the invention is achieved by a system for controlling the windshield wiper unit of a vehicle adapted to perform the methods as set out above.
The system according to the invention has the advantages according to the corresponding method claims.
