Abstract

The present invention provides a vehicle steering device, comprising: a manual steering means for manually steering steerable wheels in a vehicle; a steering-torque detection means for detecting a steering torque applied to the manual steering means; a first electromotive-torque determination means for determining a first electromotive-torque value based on the detected steering torque; a vehicle-behavior detection means for detecting behavior of the vehicle; a second electromotive-torque determination means for determining a second electromotive-torque value based on a detected value obtained by the vehicle-behavior detection means; an electric motor for applying a combined electromotive torque to the steerable wheels; and a current control means for controlling current supplied to the electric motor based on a value of the combined electromotive torque obtained by adding the first electromotive-torque value to the second electromotive-torque value.
