In a method for braking a vehicle with the aid of at least one electric machine, operated as a generator, of the vehicle, a torque generated by the electric machine is controlled by a damping control function in order to reduce a periodic deflection of a drive train, coupled to a rotor shaft of the electric machine, relative to the rotor shaft. Furthermore, a braking request signal representing a target braking torque is detected, a deactivation condition for deactivating the damping control function is identified on the basis of the braking request signal, the damping control function is deactivated when a deactivation condition is identified, a braking torque is generated based on the braking request signal by operating the electric machine as a generator, a reactivation condition for reactivating the damping control function is identified during the process of generating the braking torque, and the damping control function is reactivated when the reactivation condition is identified.

Method for braking a vehicle and brake control system for a vehicle

A method for operating a brake system of a motor vehicle. The motor vehicle has a vehicle body and multiple wheels mounted relative to the vehicle body by a wheel suspension on the vehicle body. The vehicle body is capable of executing a pitching movement by the wheel suspension. The brake system has a wheel-individual wheel brake for at least some of the wheels. A pitch angle of the vehicle body is monitored, and the wheel brakes are actuated as a function of the acquired pitch angle. The pitch angle is calculated as a function of normal forces acting on the wheels.

A method and a device for controlling the braking torque of a brake force controller at at least one wheel of a motor vehicle, in which the control pulses for a hydraulic valve is not calculated as a function of the control signal of the hydraulic pump (pump motor PM) but of the actual standstill of the pump motor PM. To detect the actual standstill of the pump motor PM, its induced voltage &mgr; is measured. When voltage &mgr; falls below a predefined minimum threshold value V , then the pump motor PM is assumed to be at a standstill.

A method and a device for anti-slip control, in particular, for traction control, in a motor vehicle, in which, in a first operating mode, a braking force is applied individually to each driving wheel with a tendency to spin to reduces its slip, and in which, in a second operating mode, an output quantity of the driving motor is additionally reduced if two driving wheels on the same axle show a tendency to spin, thereby avoiding, in an especially reliable manner, unwanted switching from the first to the second operating mode. A switch from the first to the second operating mode takes place no earlier than the end of a first waiting time that is selected in proportion to the difference between the braking forces applied to the two driving wheels with a tendency to spin and occurs after the tendency to spin of the second driving wheel is detected.
