PURPOSE:To improve riding confortability and restraining capability of fore and after posture change in a vehicular body by constituting in such a way to judge if the accelerating and decelerating condition of a vehicle is steady or transient and to control a spring constant to become hard in steady condition and control damping force to become hard in transient condition. CONSTITUTION:Engine rotation speed 1, a shift position signal 2 and a neutral switch signal 3 are input to a controller 35. The engine rotational speed varying speed VR is calculated from engine rotational speed and rotational speed stored in a memory device 40 by a processing device 39. And the variation is judged if it is steady or transient from the engine rotational speed judging level Nc, engine rotational speed varying judging level Vc according to the shift position 2 and rotational speed NR, varying speed VR, and a spring constant of a spring device 7 is made hard in steady condition and a damping force of a suspension device 4 is made harder in transient condition. Thus, riding confortability and posture change restraining force can be improved. |
