Abstract: A tire angle change motor steers a host vehicle according to a tire angle corresponding to the rotation angle of a steering wheel detected by a steering wheel angle sensor. A gear ratio calculating unit of a tire angle control unit changes the amount of steering corresponding to the rotation angle of the steering wheel required for the tire angle change motor to steer the host vehicle, depending on the amount of pushing of the steering wheel detected by the pushing amount sensor.

A pushing direction reaction force motor changes a reaction force generated against the amount of pushing of the steering wheel by the driver, depending on the speed of the host vehicle detected by a vehicle speed sensor. Therefore, the reaction force makes it possible to prevent the host vehicle from being steered by an unintended operation of the driver in various traveling states of the vehicle.

Abstract: A vehicle steering apparatus that can prevent a large returning torque from acting when a steering wheel is turned. Through processing of an assist control program, rotational torque (assist torque) of an electric motor is calculated by adding returning torque g·Trto to turning torque Tc (in actuality, subtracting the returning torque g·Trto from the turning torque Tc). The electric motor is driven and controlled in accordance with the calculated assist torque. When the steering torque is large, the calculated returning torque gain g decreases, and therefore, the returning torque g·Trto decreases or becomes zero. With this control, the greater the force (torque) required to operate the steering wheel, the smaller the influence of the returning torque, and steering feel at the time of turning the steering wheel is improved.
