PROBLEM TO BE SOLVED: To enforce a proper steering control according to the traveling state of a vehicle by correcting a steering control signal outputted from a steering control means by a correction means according to the traveling state of the vehicle. SOLUTION: When a steering wheel 1 is rotated from a state of straight traveling and target controlled variableθis calculated, control displacement Ms is generated and a steering control signal according to this control displacement Ms is outputted from a steering shaft motor control circuit 26. A steering shaft motor 11 is operated by receiving this steering control signal, a steering shaft 13 displaces and steering wheels 14a, 14b are steered. Reaction received from tires mounted on the steering wheels 14a, 14b of steering reaction F is different in the same steering angle according to the traveling states of the vehicle which are shown by speed V, a steering angleΘand a road surface, etc. A gain coefficient showing gain of this steering control signal is made variable and the gain coefficient is set according to the traveling state of the vehicle which are shown by the speed V, the steering angleΘand the road surface. |
