Patent ID: 7973506

Claim:
A device for controlling a power car window lift comprising the following elements: a car window closed obstacle signal detection element, controller and actuator; a car window opened-in-place signal detection element, controller and actuator; a car window closed-in-place signal detection element, controller and actuator; and a car window opened obstacle signal detection element, controller and actuator; the signal detection element detects a current signal of a driving motor of the car window lift, obtains a car window lift operation state signal and inputs the detected car window life operation state signal into a corresponding controller; the corresponding controller receives the corresponding signal, and sends a control signal to the corresponding actuator according to different car window lift operation state signals; the actuator controlling the driving motor to run according to the corresponding control signal; wherein the control elements of each controller include a main control element and an auxiliary control element, the main control element being a thyristor or its equivalent functional element.
