<p>The steering assembly disclosed has means for sensing changes in both lateral offset and angle between a towed and a towing vehicle, means for generating angle and offset signals responsive to such changes, means for combining the angle and offset signals to produce a joint steering input, and means for turning a steerable wheel of the towed vehicle in response to the joint steering input. The assembly has two operating modes, one in which offset signals and angle signals are subtracted to produce a joint steering input for forward travel of the vehicles and another in which offset signals and angle signals are added to produce a joint steering input for backing of the vehicles. The assembly also includes steerable wheel means, means for detachably coupling the vehicles together, and means for remotely shifting between the two operating modes.</p> |
