Abstract
A vehicle steering device includes an electric motor; a steering angle sensor; a steering torque sensor; a wheel speed sensor; a cruise controller; and a wheel-alignment support controller configured to compute an anti-one-side pull current value fed to the electric motor for suppressing a one-side pull behavior of a vehicle. The wheel-alignment support controller calculates, according to an integrated torque value, the amount of displacement of an anti-one-side pull steering angle value that corresponds to a midpoint steering angle of a steering system for suppressing the one-side pull behavior of the vehicle. When the vehicle is under cruise control and the vehicle speed is below a first threshold Vth1, the wheel-alignment support controller makes the amount of displacement of the anti-one-side pull steering angle value smaller than that obtained when the vehicle speed is equal to or above the first threshold Vth1.
