Abstract

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 “brake closed” 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.
