An arrangement for the control of at least one magnitude influencing the driving torque of an internal combustion engine of a motor vehicle in conjunction with a drive slippage regulating system is provided with a regulating system which undertakes the follow-up control of this magnitude to a predetermined desired value in steps dependent on vehicle- and outside-dependent magnitudes with an increase velocity also dependent on vehicle and outside, as a result of which excess torques reducing the traction and lateral guidance force are avoided and regulating operations which become necessary are significantly shortened.

Arrangement for controlling at least one magnitude influencing the

An installation for the forward drive regulation acting on the output torque of a drive aggregate in motor vehicles with a regulating circuit responding to the slippage of each driven wheel on which is superimposed a regulating circuit responding to exceeding an acceleration threshold value of each driven wheel which replaces the slippage regulating circuit designed for optimum traction from the regulation beginning for a predetermined duration and as a result thereof rapidly stabilizes the vehicle because only a small excess torque which can be controlled in few regulating cycles, can occur owing to the early regulation beginning.

Installation for the forward drive regulation in motor vehicles

An arrangement for controlling the propulsion or forward drive in the sense of preventing an undesired slippage of the wheels to be regulated in motor vehicles equipped with four-wheel drive, in which a driving velocity-reference signal necessitated for the regulation is derived from the minimum wheel velocity and the reference velocity is set during each regulating cycle anew into the range of the optimum friction.

Arrangement for the propulsion regulation of motor vehicles

An installation for the propulsion regulation in motor vehicles acting on the output torque of the driving aggregate for preventing the undesired slippage of the driven vehicle wheels, whereby in case of determining the slippage tendency of a driven wheel, the magnitude determining the output torque is stored and subsequently reduced to its minimum value, is increased after the termination of the acceleration phase of this wheel to a value coordinated to the maximum value of the wheel acceleration which had occurred, is kept constant at this value, and in case of a determination of the ending of the slippage tendency, is increased by a further value coordinated to the maximum value of the wheel deceleration that had occurred whereby the delayed reaction of the drive aggregate is counteracted and a more rapid regulation with slight excess torque and fewer regulating cycles is attained.
