A collision prevention method for motor vehicles is provided, in which method obstacles in front of the vehicle are detected by an on-board positioning system, a collision probability is calculated from the position data, and one or more responses to prevent a collision are triggered as a function of the collision probability. At least one of the responses is a preparatory measure accelerating the implementation of a command, which may be output later, to decelerate the vehicle, without the preparatory measure itself having any significant decelerating effect on the vehicle.

Method and apparatus for driving a solenoid valve

Control circuit for a solenoid valve

A difference .delta..sub.2 -.delta..sub.1 is formed between the steering angle .delta..sub.2 actually measured and the steering angle .delta..sub.1 calculated from the vehicle transverse acceleration, vehicle speed, and a series of constants. This difference (.delta..sub.2 -.delta..sub.1) is used to displace the working point on the .mu.-slip curve in the direction of an increase of the lateral stability, i.e., toward smaller slip values. Response can be improved by making the displacement also dependent on the rate of change of this difference or the rate of change of the actual steering angle. Preferably no reaction is produced when the difference is below a threshold angle unless one of the rates exceeds a respective threshold.
