Abstract: A drive slip control system in which, if a gearshift has been detected, at least one parameter of the drive slip controller is switched over so as to render the drive slip controller less sensitive.

Abstract: A device and method for determining values and/or generating signals, which can be used for closed-loop or open-loop controlling of the driving behavior of a vehicle equipped with a sensor system that detects wheel contact forces, includes determining the vehicle mass via the wheel contact forces that are detected, and further includes at least one of determining shifts in the wheel contact forces, and determining the required drive torque.

Abstract: An arrangement for determining the temperature of valves in the brake circuit of a vehicle is described. The arrangement includes an arrangement to measure a longitudinal wheel force, an arrangement to determine a wheel braking pressure using the measured longitudinal wheel force, an arrangement to determine a pressure drop across a valve using the wheel braking pressure, an arrangement to determine a valve solenoid current using the pressure drop, an arrangement to determine the resistance of the valve solenoid from the valve solenoid current and an applied valve solenoid voltage, and an arrangement to determine the valve solenoid temperature using the temperature-dependence of the valve solenoid resistance. Moreover, a method for determining the temperature of valves in the brake circuit of a vehicle is provided.

Abstract: A method and a system for operating a brake system of a motor vehicle having traction control are described. The brake system contains sensors which are assigned to the individual vehicle wheels and with which a quantity representing at least the driving and/or braking forces acting between the road surface and the vehicle wheel is detected for the respective vehicle wheel. For operation of the brake system having traction control, pressure quantities which describe the brake pressure established for the respective vehicle wheel are analyzed. The pressure quantities are determined as a function of the quantities detected by the sensors.

Abstract: The coefficient of friction &mgr;s between the wheels of the vehicle and the road surface is identified as a function of the slip, and the maximum drive torque MAmax which can be transmitted is determined as a function of this slip-dependent coefficient of friction &lgr;. &lgr; is corrected when there is an increased slip requirement &lgr;erf as a result of the speed of the vehicle and/or the tire mixture used.

Abstract: A method and a device for controlling traction in a motor vehicle in which a maximum transmittable driving torque is calculated using operating parameters of the vehicle and its drive unit. One of these parameters is a quantity indicating the turning performance of the vehicle in cornering, such as the yaw or transverse acceleration of the vehicle.

Abstract: In order to optimize control of drive slip, the torque demand of the drive is determined continuously taking into account the interfering torques acting on the vehicle, and the drive torque is reduced to this torque demand when instability occurs.

Abstract: An ABS or ARS is described in which additional facilities are provided for the detection of wheel vibrations. When a vibration is detected, actions for their suppression are initiated.
