Abstract
A control system and method is provided for a vehicle. The control system includes a speed sensor, a wheel angle sensor, and a vehicle position sensor. An electronic control unit (ECU) determines a yaw-rate error as a function of at least the vehicle position signal, determines a first speed limit as a function of the yaw-rate error, determines a second speed limit as a function of a vehicle lateral acceleration, and determines a third speed limit as a function of the wheel angle signal. The ECU selects the lowest of the first, second and third speed limits, generates a front wheel drive command and a diff lock command as a function of the wheel angle signal. The ECU also limits the vehicle speed to not greater than the selected lowest wheel speed limit.
