Title: Electro-hydraulic power steering system provided with function of assisting power generation of alternator
Inventor: ABE MASAO
IPC: B62D6/02
Filed: 1983-04-26
Abstract: PURPOSE:To assist steering in an optimum manner and to enable the compensation of a fall of a battery voltage caused by the heavily-loaded state of an electric motor exclusively used for a power steering, by varying, according to the speed of a vehicle, the output of a working fluid of an oil pump which is driven by the electric motor. CONSTITUTION:When a driving sensor 17 delivers a steering signal according to the operation of a steering wheel 1, the rotor current of an electric motor 5 driving an oil pump 4 varies along a characteristic curve L. In a low-speed area (an area in which a relay is ON), the electromagnetic relay device 13 of an electronic switch 21 is turned ON to supply a power to the electric motor 5. When the speed of a vehicle increases to a medium speed area (an area in which a transistor operates), the electromagnetic relay device 13 is turned OFF, and the continuity of the transistor 14 is varied with the speed of the vehicle, whereby the supply of the power is controlled. Accordingly, the voltage of a battery 25 is impressed directly on the electric motor 5 when steering is performed at low speed, and thus the motor 5 is operated by a full-load current, while it is controlled variably in accordance with the speed of the vehicle when the speed is medium or above.
