PURPOSE: To perform a drive control of a wiper with high accuracy, by providing a control computer, enabling the computer to accept interruptions with a predetermined constant interval, allowing the wiper to act normally in response to vehicle speed until an interruption occurs, and setting a timer range while an interruption is taking place.
CONSTITUTION: A control computer 100 is provided to control a wiper switch 14 and other equipments by means of an input to be fed corresponding to an output of said switch 14. The computer 100 is equipped with a timer so as to permit an interruption after the lapse of a preset time period. The wiper switch 14 is provided with a slider 149, so that a current is conducted between contacts 140 and 142 during an intermittent wiper operation, between contacts 140 and 144 during a normal wiper operation at low speed driving, or between contacts 141 and 144 during a normal wiper operation at high speed driving. When a timer interruption demand occurs, the wiper is intermittently actuated where the contacts 140 and 142 are connected, but where contacts 140 and 142 are disconnected and the vehicle speed is, for example, at 80km/hr or faster, the wiper operation will be changed to a continuous operation.
