  • Anti-pinch motor control
    Patent number: 11611297
    Abstract: A motor control system configured to detect a pinch condition of a structure actuated by a motor includes a pinch detection module configured to receive a current signal indicative of a motor current, determine a rate of change of current based on the current signal, and generate a pinch signal indicative of the pinch condition in response to either one of the motor current being greater than a current threshold and the rate of change of current being greater than a rate of change threshold. The motor control system further includes a position control module configured to control the motor to actuate the structure in response to an input and at least one of stop and reverse the motor in response to the pinch signal.
