Abstract

A method and system are provided for vehicle stabilization of a hybrid vehicle in an event of brake slip of the drive wheels or an increased risk thereof. The method presupposes that the hybrid vehicle includes, between the internal combustion engine and the electric motor, a clutch by which the torque of the internal combustion engine can be decoupled from the drive wheels. With the clutch engaged, the resulting torque on the electric motor is produced by the torque of the internal combustion engine and the torque of the electric motor. The presence of a specific vehicle condition indicative of brake slip of the drive wheels or a risk thereof is recognized. If such a vehicle condition is recognized, the clutch between the internal combustion engine and the electric motor is released and the torque of the electric motor is increased.
