A brake control system has a controller (52, 53, 54) including hysteresis. To prevent over-shoot of control operation if a comparison between actual braking pressure (P.sub.act) and commanded pressure (P.sub.com) is applied to control valves which, for example, operate pneumatically, so that the brakes will not instantaneously respond, a difference pressure threshold (.DELTA.P.sub.G) is determined and, when the difference pressure level is passed by the difference pressure signal, the valves are controlled to operate in pulse operation, in which each pressure pulse (T.sub.E) is followed by a quieting or pressure-OFF time (T.sub.BER). The pulse sequence and the timing of pulses and pulse gaps is controllable in accordance with pressure levels, operating parameters, pressure difference levels and the like.

A control device for internal combustion engines serves to maintain selectable speeds at a constant value. The control device comprises an actual value-desired value comparison stage for the speed, at least one integrator, as well as storage capacity for the integrator value. The engine has a speed device and within a selectable speed range of the engine, the speed device operates in accordance with its function. Outside of the selected speed range, particularly at higher speeds, the integrator serves as a storage device so that when the speed again enters the control speed range, the stored value serves as a starting point for the renewed control operation. In this way, a rapid control action is insured upon each re-entry into the control range, besides providing an exact control operation within the range.

In a motor vehicle, the presence of laterally acting external forces is detected by an appropriate sensing device. The first time derivative of the sensed signal is used to initiate steering gear deflection to counteract the external deflecting forces.
