Abstract
A vehicle system configured to control a trailer alignment routine includes a hitch mounted on a vehicle and a controller. The controller is configured to identify a coupler position of a trailer and control motion of the vehicle to toward an aligned position. The controller is further configured to control a braking procedure of the vehicle including a plurality of concurrent deceleration control procedures in response to a portion of the vehicle passing a gradual stopping distance. The concurrent deceleration procedures include monitoring an elapsed time following the portion of the vehicle passing the gradual stopping distance and monitoring a remaining distance to the aligned position based on a velocity of the vehicle and comparing the remaining distance to a rapid stopping distance.
