Abstract:
A method of reducing current consumption of an electric hydraulic power steering system for a vehicle includes determining whether or not a steering wheel is manipulated after an engine is started, and activating a sleep mode if it is determined that the steering wheel is not manipulated and if a vehicle speed is lower than a reference value for activating the sleep mode, or if it is determined that the steering wheel is manipulated and if an amount of current conducted in a motor, a vehicle speed and a steering angular velocity are lower than respective reference values for a predetermined time. According to the method, it is possible to reduce current consumption when the steering wheel is not manipulated and improve the vehicular fuel efficiency.
