PROBLEM TO BE SOLVED: To solve the problem of failing to obtain the original responsiveness of an actuator corresponding to vehicle speed in spite of a region hardly influenced by the change of a transmission ratio when suppressing the change of the transmission ratio caused by the sudden change of vehicle speed in the case a steering system is near the neutral. SOLUTION: This steering control device for a vehicle is provided with a determination map as shown in Fig. When determining, whether the relation between longitudinal acceleration g and the operating angleθm of the actuator is in an update authorizing region of authorizing the update of a transmission ratio G following the change of vehicle speed, or an update inhibiting region of inhibiting the update, is determined. |
