Abstract
An electronic system that includes a trailer sensor, a lock sensor and a control circuit determine whether a trailer hitch assembly is properly coupled to a trailer. The trailer sensor senses the position of the trailer relative to the trailer hitch assembly and the lock sensor senses the position of the locking mechanism. The control circuit is coupled to the trailer sensor and the lock sensor and masks an output of the lock sensor for a first predetermined stabilization period after the control circuit initially determines that the trailer hitch assembly is properly coupled to the trailer.
