Abstract
Systems and methods for detecting pinching caused by movement of a steering column include determining a predicted velocity of the steering column, determining an actual velocity of the steering column, determining whether the predicted velocity is greater than the actual velocity of the steering column, in response to determining that the predicted velocity is greater than the actual velocity, calculating an accumulated velocity difference indicative of differences between the predicted velocity and the actual velocity, and generating a signal indicating whether pinching is detected based on the accumulated velocity difference.
