Automatic wiper control apparatus in accordance with the size of the raindrop

摘要

The subject innovation relates to an automatic wiper control device for controlling the driving speed of the wiper in accordance with the size of the raindrops.; Conventional wiper wiper speed and without rain relationship is constant, just be that the driving speed depend on the operation of the driver frequently it is inconvenient due to the number of operations of the operation.; And the subject innovation is the input port of the amplifier 12 and the analog / digital converter controller 16 to turn mediate (14) connected to a pressure sensor 10 for sensing the pressure of the raindrop on the vehicle, the controller (16 ) is input raindrops been to remove the amount of pressure to the multi-level memory (18 sewn to store the screen look-up table a control signal for driving the wiper in the step-by-step to be generated off) connected to the car is a controller (16) digitizing by the raindrops pressure signal that is read out from the look-up table in accordance with a control signal memory (18) being designed configured to control the rotational speed of the wiper drive (20).
