Title:
WIPER CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JP3111665
Kind Code:
B2
Abstract:
PURPOSE: To prevent the flapping and floating-up of a wiper blade beforehand by presupposing the practical use of a pair of drive elements such as semiconductor switching elements.
CONSTITUTION: In the case of a wiping operation state by means of a wiper blade, when a cam switch CS falls into an earth side changeover state from an electric feed side changeover state in a state in which a wiper switch circuit SW is made an intermittent operation mode INT or a stop operation mode OFF, a micro computer 60 makes an FET 70 OFF, and cuts off electric feed to a wiper motor 40a from a battery B. As a result, the wiper motor 40a conducts inertia deceleration rotation during a predetermined delay time that is equivalent to the open sphere of the cam switch CS. When the micro computer 60 delays by a predetermined delay time after the FET 70 becomes OFF and puts an FET 80 ON, the wiper motor 40a displays power generation brake operation and stops at a rotary position opposite to the automatic stop position of the wiper blade.
