In a method for warning a vehicle driver of a risk of the vehicle overturning about its longitudinal axis, a control device detects the current transverse acceleration of the vehicle and emits a warning signal based thereon when a risk of overturning is presented. The warning signal is dependent upon at least one transverse acceleration value, which is critical for overturning, detected by the control device while the vehicle is being driven, and a measurement of the transverse acceleration of the vehicle at which the vehicle would actually overturn about its longitudinal axis. The transverse acceleration value that is critical for overturning is determined automatically based on the vehicle behavior exhibited during driving on a curve.

In a method for signaling a braking process on a trailer vehicle coupled to a towing vehicle, at least one light on the trailer is actuated with an emergency brake signal during emergency braking and with a normal signal during a different driving state. The emergency brake signal causes a different actuation of the light than does the normal signal. The light can be actuated by a control signal of the towing vehicle, and the actuation state of the light can be influenced by at least one control device on the trailer. The control device detects the control signal generated by the towing vehicle and fed to the trailer to actuate the light, and analyzes the control signal. If it detects that the control signal is an emergency brake signal, it does not carry out a dedicated actuation of the light, or it effects a different actuation of the light than in other cases.

To prevent the immobilizer for a trailer vehicle of a vehicle train from intervening when the trailer vehicle is moving in traffic, the electronic trailer braking system switches the vehicle service braking system into a 'brake closed' or 'brake released' state when the parking brake in the towing vehicle is actuated in closing direction or in release direction. The immobilizer is activated such that the electronic trailer braking system is only actuated by remote-control by a control device in order to switch the parking brake of the braking system permanently into the &#x201c;brake closed&#x201d; state when the trailer vehicle is decoupled from the vehicle train and is parked. The immobilizer is deactivated when the trailer vehicle is coupled to the vehicle train and the parking brake in the towing vehicle is engaged.
