Abstract
A powered trailer for aiding a powered vehicle in moving a load trailer is selectively connected to the vehicle by a tongue assembly. A sensing device mounted on the tongue assembly senses the position and motion of the vehicle relative to the powered trailer. Trailer engine speed and brake control devices control the engine and brakes of the powered trailer dependent on signals from the sensing device so that the engine and brakes of the powered trailer operate in coordination with those on the vehicle. The sensing device has operating modes for detecting relative motion when the powered trailer is traveling either in forward or rearward directions, and can be placed in an unactivated state in either mode. The sensing device cannot be changed from one mode to another without the sensing device being in its unactivated state.
