摘要： A base transmission ratio Gbase is determined according to the vehicle speed and a compensation amount &agr; is determined for each of feed steering case and return steering case during acceleration/deceleration. Based on this, the transmission ratio G of a transmission ratio varying mechanism is set as G=Gbase+&agr;.

摘要： A vehicle steering apparatus having a variable gear ratio unit arranged midway along a steering transmission system for connecting a steering wheel and a tire to change a transmission ratio upon driving a motor includes a connecting unit for stopping actuation of the variable gear ratio unit in accordance with an external signal to connect the input side of the variable gear ratio unit which is connected to the steering wheel to the output side of the variable gear ratio unit which is connected to the tire. Even if a reverse input acts from a tire side during traveling, the relationship between the steering amount of the steering wheel and the turning amount of the tire can be kept unchanged.

摘要： In a vehicle steering apparatus having a variable gear ratio unit arranged midway along a steering transmission system for connecting a steering wheel and tires to change the transmission ratio, and an ECU for variably controlling the variable gear ratio unit in accordance with the state of a vehicle, the variable gear ratio unit includes a motor controlled by the ECU, and a reducing mechanism which has a transmission ratio for allowing to maintain the steering angle of the steering wheel with respect to an RF reverse input and transmits the rotation of the motor to the output side. Even if a reverse input acts from a tire side during traveling, the relationship between the steering amount of the steering wheel and the turning amount of the tire can be kept unchanged.
