ABSTRACT:
An anti-pinch safety system includes an electric motor operatively coupled to a vehicle opening device to move the vehicle opening device between an open position and a closed position, and a sensor operatively coupled to the electric motor for sensing velocity of movement of the vehicle opening device. A processor is coupled to each of the sensor and the electric motor, along with a memory containing stored instructions to be executed by the processor. The stored instructions include: a) calculating a pinching force of the vehicle opening device in accordance with changes in velocity sensed by the sensor; b) detecting a pinched condition by comparing the pinching force to a predetermined force value; and c) stopping closing movement of the vehicle opening device when the pinched condition is detected.
