Steering device for vehicle

A steering device for a vehicle having a reaction actuator acting a steering reaction force on a steering member, comprising;

• a steering angle detecting member detecting a steering angle of said steering member;
• a reaction controller controlling said reaction actuator according to said steering angle detected by said steering angle detecting member;
• and
• a steering torque detecting member detecting said steering torque acted on said steering member;
• said reaction controller includes an analog-digital transforming member transforming an analog output signal of said steering torque detecting member to a digital output signal to control in a feedback way said reaction actuator based on said reaction force signal of said output signal transformed by said analog-digital transforming member where said steering angle detecting member detects said steering angle around a predetermined range including middle point, and to control said reaction actuator in an open-loop way without feed-backing said steering reaction force detected by said steering torque detecting member where said steering angle detecting member detects said steering angle out of said predetermined range.
