Abstract
The invention relates to a clamping-prevention detection method for an automotive power-driven part. After a motor shaft is decelerated through a speed reducer, a pinion is driven to rotate and drags the power-driven part to move linearly through a sliding screw rod. The clamping-prevention detection method is characterized by comprising the steps of: measuring the current rotation speed and the voltage of the motor, acquiring the current output torque of the motor according to the current rotation speed and the voltage of the motor, comparing the current output torque of the motor with the torque of the motor under normal load, and acquiring a clamping force applied to a barrier according to a difference value.
