SPEED REGULATION CONTROL SYSTEM FOR WINDSHIELD WIPER

WIPO Patent Application WO/2020/224645

A1

A speed regulation control system for a windshield wiper, comprising an electric motor (3), a connecting rod structure, a control module (1) and a sensing module (2), wherein the connecting rod structure converts a unidirectional movement of the electric motor (3) into a reciprocating movement of a windshield wiper on a glass panel; the sensing module (2) is used for sensing a discrete signal or a continuous signal according to one cycle of the unidirectional movement of the electric motor (3); the control module (1) is respectively in electrical signal connection with the electric motor (3) and the sensing module (2); and the control module (1) provides, according to a signal fed back by the sensing module (2), a target driving effective voltage corresponding to the signal and for controlling the electric motor (3) to the electric motor (3), such that the electric motor (3) is driven by means of the target driving effective voltage corresponding to each group of signals during the unidirectional movement of the electric motor (3), thereby regulating the movement speed of the windscreen wiper.
