Abstract: A method for determining a friction coefficient potential of a road surface. A total torque for operating a vehicle is unequally distributed among at least two wheel torques at wheels of the vehicle. The friction coefficient potential is ascertained using a detected slip between the road surface and at least one of the wheels and the wheel torque present at the wheel.

Abstract: A method for operating an electric motor for braking a vehicle, including controlling the electric motor in such a way that the vehicle is slowed or decelerated with the aid of a motor braking torque exerted by the controlled electric motor. The method includes ascertaining whether a requested setpoint speed change is in a predefined normal range, and if so, the electric motor is controlled in such a way that a load to be applied by the electric motor remains less than or equal to a nominal load capacity of the electric motor. If the requested setpoint speed change is outside the predefined normal range, the electric motor is controlled in such a way that the load to be applied by the electric motor exceeds the nominal load capacity of the electric motor, at least during a predefined overload operation time interval.

Abstract: A device for compensating for a disturbance yaw moment in a vehicle having at least two wheel-individual drives is described. In particular in vehicles having multiple wheel-individual electric drives, wear or heavy use may result in a defect of a single drive. Since this drive is coupled to a single wheel of the vehicle, a strong disturbance yaw moment may be generated thereby which may result in the vehicle breaking away if countermeasures are not taken. It is provided to compensate for the disturbance yaw moment at least partially by effectuating a compensation yaw moment by retarding one or multiple of the other wheels of the vehicle in a targeted manner, when an event is detected which indicates a disturbance yaw moment of the vehicle and in which one wheel of the vehicle is excessively retarded due to a defect on a wheel-individual drive assigned to the wheel.

Abstract: In a method for generating a difference moment that is acting on a vehicle, the actuation of a wheel brake unit sets a difference moment between two vehicle wheels, and a difference moment is generated via an additional actuator, separately from the wheel brake unit. The setting of the desired difference moment takes place primarily via the additional actuator, the wheel brake unit being used in supplementary fashion in the event that the difference moment is unable to be set via the additional actuator.

Abstract: A method for stabilizing a vehicle in an extreme driving situation, in particular in an overcontrol or undercontrol of the vehicle, in which a vehicle controller intervenes in the driving operation by an automatic actuation of at least one wheel brake in order to stabilize the vehicle. The vehicle is able to be stabilized much more rapidly if an additional drive torque, which produces an additional yawing moment that augments the stabilizing effect of the braking intervention, is generated at at least one wheel.
