The invention relates to an apparatus and a corresponding method for improvement of the braking behavior of a hybrid vehicle. There will be described a control unit for a vehicle. The vehicle includes an electric machine, which is arranged to cause a drag torque to a first wheel axle of a plurality of wheel axles of the vehicle. The vehicle further includes a friction brake, which is arranged to cause a friction torque at a wheel axle reibbremsbaren of the plurality of wheel axles. The control unit is adapted to recognize a reduction of the electric machine caused by the drag torque at the first axle. Furthermore, the control unit is adapted to cause the friction brake to compensate for the reduction of induced drag torque of the electric motor by generating an additional friction torque on the wheel axis reibbremsbaren at least partially.
