Abstract

An electric power steering apparatus for a vehicle, includes: a first auxiliary steering unit for assisting with steering power while rotating a steering shaft in a forward or reverse direction with a driving power of a first motor; a second auxiliary steering unit for assisting with steering power while sliding a rack bar in one or an opposite direction with a driving power of a second motor; a torque sensor for detecting a rotary torque of the steering shaft; a speed sensor for detecting a speed of the vehicle; and an electronic control unit for transmitting a target current value control signal to the first motor and the second motor respectively in response to input signals input from the torque sensor and the speed sensor, respectively.

Description

technical field [0001] The present invention relates to an electric power steering device for a vehicle, and more particularly to an electric power steering device for a vehicle, which uses two auxiliary steering units for providing auxiliary steering force when a driver operates a steering wheel, which To distribute an auxiliary steering force according to the increase in speed and weight of the vehicle, reduce the load applied to either of the two auxiliary steering units, reduce operating noise, increase durability, reduce costs, and even when used in trucks or The situation where the motor of a bus requires a relatively high steering force compared to a small passenger car allows the use of a motor with a low output power to provide a sufficient auxiliary steering force, thereby improving driver convenience, and when Fuel efficiency is improved while energy efficiency is increased, and steering operation can be safely maintained even when one of the auxiliary steering unit...
