Abstract
A control method is provided for a vehicle, especially a utility vehicle trailer, that has at least one lifting axle that can be lowered and raised in a controllable manner and/or at least one steered axle that can be locked and unlocked in a controllable manner, and that also has a control device operable to control the lifting axle and/or the steered axle. When the vehicle is traveling in reverse, the control device automatically generates a control signal that lowers the lifting axle, and/or automatically generates a control signal that unlocks the steered axle. The control device can be embodied as an electronic control unit having a processor suitably programmed to carry out the foregoing process steps. The control device can be incorporated into a vehicle control system for a vehicle having an anti-lock braking system or an electronically controlled braking system.
