Electronic control device for a direct current electric motor having two supply terminals for a drive system operating in back-and- forth mode, and the application of such a device to a vehicle screen wiping system
A drive motor for a motor vehicle screen wiping apparatus operates with repeated reversals of its direction of rotation, and is controlled by a control circuit which is connected to a transistor arranged in the power supply path for the motor, in series with it. The transistor is put into conduction at a time, and in a manner, such as to reduce the audible noise caused by the repeated reversals.
