An automatic docking system for docking a towing vehicle with a towed vehicle includes a sensing device, a controller, an automatic steering system, an automatic braking system, and a plurality of targets. The sensing device detects the plurality of targets located on a hitch of the towed vehicle. The controller determines the location of the towing vehicle relative to the towed vehicle based on the detection of the plurality of targets. The controller automatically steers the towing vehicle towards the towed vehicle to assist in the docking of the towing vehicle to the towed vehicle. The controller engages the automatic braking system to slow or stop the towing vehicle as required.

Vehicle docking assistance system

An exhaust after-treatment system for a vehicle including a dosing agent that is selectively injected into an exhaust from a dosing agent supply includes a first module that determines a level of a dosing agent source and a second module that determines whether the vehicle is at a convenient location for replenishing the dosing agent source. A third module selectively inhibits vehicle operation if the level of the dosing agent source is below a threshold level and the vehicle is at the convenient location.
