ABSTRACT:
To prevent slip-out or slide-out of a vehicle operating in a curve, the lateral stability or, respectively, instability of the vehicle is determined and, if instability or incipient instability is sensed, the vehicle is automatically braked, and/or engine torque of the vehicle engine is reduced. A reference parameter K, which may be variable in accordance with vehicle operating and operation conditions, is compared with a quotient of change of lateral forces applied to the front (V) and hind or rear (H) axles with respect to the change of the slip angle (.delta..sub.V, .delta..sub.H), and if the change of lateral force (.DELTA..sub.S /.DELTA..sub..delta.) at the respective axles, and passes the reference K. The respective axles can then be together or selectively braked in accordance with the extent of deviation from said comparison reference K and/or engine torque also reduced.
