Abstract: A method, for a trailer brake control device of a vehicle trailer with an electric drive, includes receiving at least one acceleration request signal with a requested positive acceleration or a requested negative acceleration and further receiving a status signal with at least one status variable of the electric drive of the vehicle trailer. The method also includes generating, with a controller of the trailer brake control device, at least one brake actuation signal for at least one friction brake of the vehicle trailer and a torque request signal for the electric drive, each based on the at least one acceleration request signal and the status signal. Furthermore, the method includes outputting the brake actuation signal and the torque request signal via at least one output and/or at least one interface of the trailer brake control device.

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.

Abstract: In a method for checking vehicle tires, wheel sensor signals of at least one wheel of the vehicle are recorded over a time period, and a comparative value is determined to indicate a travel distance of the wheel. A reference travel distance covered by the vehicle in the time period is determined independently of the wheel sensor signals, and an individual ratio value of the wheel is formed from the wheel travel distance and the reference travel distance. The behavior of the ratio value over time is determined, and a determination is made concerning changes to the tire of the wheel.
