A method is for operating a trailer vehicle having an electric drive and friction brakes. The method includes determining a differential mass between a first mass of a driven axle of the trailer vehicle and a second mass of a non-driven axle of the trailer vehicle, and determining a deceleration torque depending on the differential mass. The method further includes generating at least or exactly the determined deceleration torque with the electric drive when the friction brakes are activated. A trailer brake control unit is for the trailer vehicle. The trailer vehicle includes the trailer brake control unit. A combination includes a towing vehicle and a trailer vehicle having the trailer brake control unit.

An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.
