A method for controlling propulsion in motor vehicles is described which detects when the vehicle approaches the limiting value for lateral acceleration independently of the condition of the load, the tires, the roadway and so forth in that a measurement value for the lateral acceleration, the yaw velocity or the difference of the front wheel speeds of rotation is compared with a mathematical value determined by the use of a mathematical formula, in which method this mathematical value is phase-delayed in a filter and corrected in a first correction unit and the mathematical formula used is corrected in a second correction unit.

Method and device for controlling propulsion in motor vehicles

A propulsion control system for motor vehicles for maintaining stable driving conditions, having a computer unit for determining a desired value or a tolerance range for the rotational speed difference of the front wheels or of the lateral acceleration or of the yaw velocity, and having a comparator unit in which this desired value or tolerance range is compared with the measured actual value, in which case the difference between the actual value of the desired value or tolerance range is used as a control signal for the brakes of the wheels and/or for a power control element of the vehicle engine.

Propulsion control using steering angle and vehicle speed to determine

The invention relates to a device for damping pendulum oscillations of a trailer hitched to a coupling of a motor vehicle. For this purpose, the coupling at the rear of the motor vehicle is horizontally adjustable at right angles to the longitudinal axis of the vehicle, and damping means serve for adjusting the coupling, in proportion to the deflection of the trailer drawbar, from a position lying on the longitudinal axis of the vehicle in the direction of the side of the motor vehicle into which the trailer is swerving. Transverse movements of the coupling relatively to the superstructure of the motor vehicle cause a continuous shifting in the instantaneous fulcrum or center of rotation of the trailer drawbar forwardly along the longitudinal vehicle axis, whereby interfering forces impairing the driving direction of the trailer are counteracted and driving stability is ensured.
