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.

An articulated vehicle having at least two vehicle parts which are connected to and articulated relative to each other is provided. The vehicle includes a front vehicle part and at least one rear vehicle part arranged behind the front vehicle part with respect to a longitudinal direction of the vehicle. The front vehicle part has a first drive unit including at least an electric motor and a first energy storage system; and at least one rear vehicle part has a drive unit including at least an electric motor and an energy storage system. Each rear vehicle part includes an individual electrical system that is galvanically isolated from the front vehicle part and from each other at least under normal driving conditions.

A semitrailer includes a wheel and an electric machine for driving the wheel, wherein the electric machine is configured so as to be operable as an electromotive brake in a braking state.
