DISPOSIZIONE CIRCUITALE PER IL MOVIMENTO DI UN ELEMENTO MOVIBILE,IN PARTICOLARE PER IL MOVIMENTO DI LASTRE DI CRISTALLO O SIMILI IN VEICOLI A MOTORE |
摘要 |
A safety control circuit for electric motors of power windows of automotive vehicles and which differentiates between a tight fitting of the window pane and an obstacle blockage. The motor current is selectively detected to provide a signal representative of the instantaneous rather than static current values. The detected signal is compared to a reference signal. When the detected signal exceeds the reference signal by a given value or longer than a predetermined interval, which indicates that an obstacle blockage has occurred, the motor current is switched off or reversed. |
