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.

Abstract: A process for increasing the stability of a vehicle upon acceleration on a roadway with a non-homogenous coefficient of friction, whereby a drive wheel is acted on by a braking force on a side with a low coefficient of friction by means of a drive slip regulation. A value (pASR) is determined which corresponds to the braking force (FB,ASR) set by the drive slip regulation (ASR). The value determined (pASR) is used for the determination of a disrupting yaw momentum (MZ), and a control portion (??Z) of a supplemental steering angle (??) is determined in dependence on the disrupting yaw momentum (MZ). An apparatus for the implementation of the process is also provided.

Abstract: A method for controlling a brake pressure in at least two wheel brakes preferably mounted on one axle of the vehicle, is performed during a braking operation on a road surface having a heterogeneous coefficient of friction. This method works as follows: A low coefficient of friction side and/or a high coefficient of friction side is detected, a stability index representing the driving state of the vehicle is formed, the stability index is evaluated on the basis of the low coefficient of friction side and/or of the high coefficient of friction side and the brake pressure is altered in at least one wheel brake as a function of the value of the stability index and as a function of the result of the evaluation of the stability index on the basis of the low coefficient of friction side and/or the high coefficient of friction side.
