Apparatus for providing hydraulic line pressure and vacuum pressure to the braking and steering subsystems of a wheeled motor vehicle comprises one or more battery powered electric motors which drive one or more of a hydraulic pump and a vacuum pump. When the engine is stopped while the vehicle is moving, to save fuel, the electric motor(s) drive the pumps, so that hydraulic pressure and vacuum are provided, for safe operation of the vehicle.
