PURPOSE:To make stable steering wheel operation performable all the time even in a turning drive, by controlling rear wheels for their turn-steering according to a detection value of tire inflation pressure, in case of a steering device which makes a turn-steering angle for these rear wheels controllable. CONSTITUTION:In case of a device which operates rear wheel turn-steering information d0 at a computer 12 in which each output signal out of a lateral acceleration sensor 13 and a front wheel turn-steering angle sensor 14, etc., is inputted, and turns and steers rear wheels 11 through a servo actuator 8 according to the operation result, the required control information d1 on rear wheel turn- steering is secured on the basis of each detection signal out of each of inflation pressure sensors 15-18 installed in each of front and rear wheels 5 and 11. Then, this control information d1 is added or subtracted to or from the said rear wheel turn-steering information d0, and the control information of (d0+d1) or (d0-d1) is fed to the said actuator 8, controlling the turn-steering of rear wheels. That is to say, for example, when the tire inflation pressure becomes smaller than the reference value, each rear wheel is turn-steered as far as the specified angle in a turn-steering direction of each front wheel 5. |
