    • PROBLEM TO BE SOLVED: To provide a vehicle steering device capable of efficiently using a reaction force actuator and applying appropriate terminal reaction force corresponding to a situation to a steering wheel.
      SOLUTION: When a steering angle of the steering wheel is within an angle range from a lock reaction force reference steering angle θlock to a limit steering angle θlimit, lock reaction force to be applied to the steering wheel is determined so as to be reduced as steering angle speed ω and vehicle speed V decrease. Thus, appropriate lock reaction force and terminal reaction force corresponding to a steering state and a traveling state can be applied to the steering wheel, and unnecessary increase in electric power consumption and heat generation of an electric motor for steering reaction force can be suppressed.

    • PROBLEM TO BE SOLVED: To provide a vehicular steering device for guiding the turning direction of a turning wheel for stabilizing the behavior when a vehicle makes a turn to a driver considering the side slip angle of a vehicle body applying during the turning state of the vehicle. SOLUTION: An electronic control unit 36 inputs the side slip angle β of a vehicle body in Step S11. Next, in Step S13, the dynamic zero point δ0 for reducing the lateral force generated on a vehicle attributable to the side slip angle β of the vehicle body is calculated by using the side slip angle β of the vehicle body. Next, in Step S14, the turning angle δa expressed by the difference between the turning angle δ detected by a turning angle sensor 33 and the dynamic zero point δ0 is calculated. Next, in Step S15, the reaction torque Tz in a predetermined relationship to the turning angle δa is calculated. In Step S16, an electric motor 23 is drive-controlled so that the calculated reaction torque Tz is generated. Thus, the adequate turning direction of a steering wheel 11 is guided to a driver.
