ABSTRACT:
An electrically powered vehicle, e.g. a forklift truck or other utility-type battery-powered vehicle, is provided with a hydraulic power-steering system with a pump driven by an electric motor. A circuit is provided to cut out the power-steering pump motor when the vehicle attains an elevated speed, thereby reducing battery drain during period in which power-steering is not normally required.
