Abstract
Abstract A device for automotive vehicles including an antiblocking mechanism and means for skid prevention. The device essentially includes measuring instruments which detect the instantaneous driving condition and which are coupled with a control mechanism responsive to specific critical values of the vehicle. This control mechanism triggers actuatable means for the automatic control of at least one device serving to keep the vehicle on course upon reaching a predetermined critical value of lateral acceleration.
