Abstract
A system and method are provided for steering control during vehicle reverse operation when maneuvering a trailer in a reverse direction with a desired turn angle. The system has a P-I-D cascade structure and includes a rear video camera for providing images to determine a trailer angle, a yaw angle determination device, a steering angle sensor, a vehicle interior display with an input device, and a vehicle speed determination device. When a trajectory mode is selected and a desired turn angle value are received, an electronic processor determines a trailer trajectory based on the desired turn angle value, the trailer angle, vehicle yaw angle, and physical properties of the vehicle and trailer. The trailer trajectory is displayed on the vehicle interior display with the rear camera image. When a driver selects an automatic steering maneuver mode, the trailer tow assist system automatically controls steering of the vehicle.
