PROBLEM TO BE SOLVED: To provide an electronic-controlled vehicle steering device capable of alleviating a steering burden of a driver in a long turning motion while maintaining the priority of avoidance performance. SOLUTION: The vehicle steering device 10 comprises an operation element 11 for allowing a driver to perform steering operation, a steering angle sensor 14, a front wheel turning mechanism 200 for changing the direction of a turning wheel, a yaw rate signal acquisition unit 34 for taking out a yaw rate signal SG3 related to the yaw rate of a vehicle, an azimuth angular signal generation unit (an integration operating unit 35) for generating an azimuth angular signal SG2 related to an azimuth angle at which the vehicle proceeds, a subtraction unit 32 for subtracting the yaw rate signal or the azimuth angular signal according to a vehicle speed from an operational amount signal outputted from the steering angle sensor, and a drive control unit (a second output adjustment unit 33) for driving the front wheel turning mechanism according to the deviation signal outputted from the subtraction unit.
