Abstract

본 발명은 엔진력에 동기하는 유압배력장치를 이용한 동력조향시스템에 관한 것으로, 특히 차량전원으로 구동하는 비상배력장치를 겸비하고, 고속주행중 고장으로 인한 엔진정지시 엔진의 정지유무를 판별하여 비상배력 장치를 구동시킴으로써 안전한 운행을 유도할 수 있는 비상배력장치를 겸비한 동력조향시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power steering system using a hydraulic power booster synchronized with engine power, and in particular, has an emergency power supply driven by a vehicle power supply, and determines whether the engine is stopped when the engine is stopped due to a failure during high speed driving. The present invention relates to a power steering system having an emergency power supply device capable of inducing safe driving by driving a device.

본 시스템은 엔진의 정지시 차량전원에 의해 작동되는 비상유압배력장치를 구비하므로 고속주행시 엔진정지에 따른 차량의 조향불능으로 인한 사고를 방지할 수 있다.This system is equipped with an emergency hydraulic power device operated by the vehicle power supply when the engine is stopped, it is possible to prevent an accident due to the steering failure of the vehicle due to the engine stop during high-speed driving.
