SPEED CONTROL FOR MOTOR VEHICLES

摘要

A trailer backup assist system is provided herein. The trailer backup assist system includes a hitch angle sensor configured to determine a hitch angle between a vehicle and a trailer attached thereto. An input device is configured to accept an input command corresponding to a trailer path command curvature. A controller is configured to determine a vehicle threshold speed limit by determining a first vehicle speed limit based on the hitch angle and a second speed limit based on the command curvature. The controller generates a command to limit vehicle speed in a reverse direction below the threshold speed limit.
