Abstract
A trailer backup assist system for vehicles utilizes surface slope data to provide an alert to an operator if a problematic operating condition is present and/or imminent while the vehicle is backing up with a trailer attached thereto. The trailer backup assist system may also be configured to utilize surface slope data to control steering, braking, or other vehicle operating parameter while the vehicle is backing up with a trailer attached thereto. The trailer backup assist system may also be configured to generate a warning and/or control the vehicle if a jackknife condition is imminent. The surface slope data may be obtained utilizing sensors on the vehicle, or the surface slope data may be obtained utilizing a database that includes topographical data.
