摘要： A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.
