Abstract
An electronic system monitors a trailer hitch assembly that has a hitch plate with a throat for receiving a kingpin of a trailer and a locking mechanism for locking the kingpin in throat. The system determines whether the trailer hitch assembly is properly coupled to the trailer and includes a trailer sensor, a lock sensor, and a control circuit. 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. The control circuit determines whether the trailer hitch assembly is properly coupled to the trailer by taking into account the sequence in which the trailer sensor and the lock sensor sense the respective positions of the trailer and the locking mechanism, as well as, the time periods elapsing between the sensing at such positions.
