Unintended standstill response in an assisted hitching operation

A system for assisting in aligning a vehicle for hitching with a trailer includes an imaging system, a vehicle control system including at least one vehicle sensor, and a controller. The controller controls the vehicle using the vehicle control system to move the vehicle into an aligned position, where a hitch ball on the vehicle is aligned with the coupler, including monitoring a signal from the vehicle sensor and tracking a position of the coupler relative to the hitch ball in image data. When the signal indicates an unintended stopped vehicle state, the controller determines a distance from the hitch ball to the coupler. If the distance is above a predetermined threshold, the controller controls the vehicle control system to cause the vehicle to move. If the distance is below the predetermined threshold, the controller indicates the unintended stopped vehicle state to a driver of the vehicle.
