Pinch detection for column adjustment actuators

A method for adjusting a position of a steering column includes adjusting a position of the steering column, determining a predicted velocity of the steering column, determining whether the predicted velocity is greater than an actual velocity of the steering column, and generating a signal indicating whether pinching is detected based on the determination of whether the predicted velocity is greater than the actual velocity. Generating the signal includes determining whether the predicted velocity is greater than the actual velocity, in response to a determination that the predicted velocity is greater than the actual velocity, determining an accumulated difference between the predicted velocity and the actual velocity over at least one of a predetermined time period and a predetermined number of samples, and generating the signal based on a determination of whether the accumulated difference exceeds a threshold.
