Vehicle steering apparatus
First Claim
1. A vehicle steering apparatus which uses a steering motor to supply a steering mechanism with steering force corresponding to a steering amount applied to a steering member, comprising:
- a reaction force motor for supplying the steering member with steering reaction force;
a current sensor for detecting a motor current of the steering motor; and
a controller capable of performing operations of;
extracting component within a predetermined frequency range out of the motor current detected by the current sensor; and
driving the reaction force motor so as to supply the steering member with steering reaction force corresponding to the extracted component and steering reaction force corresponding to the steering amount.

Abstract
A current sensor 8a detects a motor current of a steering motor 5 which supplies a steering mechanism 1 with steering force corresponding to the steering amount applied to a steering wheel 2. A main controller 4 extracts component within a predetermined frequency range out of a motor current detected by the current sensor 8a, amplifies the extracted component and drives a reaction force motor 3 in a controlled manner so as to supply the steering wheel 2 with steering reaction force corresponding to the steering amount applied to the steering wheel 2 and steering reaction force corresponding to a current of the component, which has been extracted and amplified. The vehicle steering apparatus constructed as above can supply steering means with steering reaction force corresponding to component within a predetermined frequency range of a motor current of the steering motor.
