Electric car window controller and anti-pinch control method
InactiveCN102536037AAvoid complex installationsSave material costWindowsWindscreensElectric carsEngineering
The invention provides an electric car window controller with an anti-pinch function and an anti-pinch control method. During the motion process of an electric car window, the number of fluctuations of motor current during rise is added and is subtracted during fall, and motor current is constantly detected. If motor overcurrent occurs during rise of the car window, the detected net value of the number of fluctuations of motor current is compared with the number of fluctuations of maximum current of an electric window anti-pinch area. If the detected net value is smaller than the number of fluctuations of maximum current, a user can judge that an obstacle exists in the electric window, and the controller controls the car window to fall back. The electric car window controller with the anti-pinch function and the anti-pinch control method require no Hall sensors, have low requirements for configured motors, simplify design for hardware circuits, bring convenience to installation and save cost.
