PURPOSE:To decrease the action effected on passengers by constructing a car frame in such a way that an acceleration and deceleration of a car and change of its posture are detected, a shock absorbing device is controlled in its extension and contraction and the posture of a car is turned to the opposite direction, and force caused by accleration and deceleration of speed is directed to the floor surface. CONSTITUTION:A pitch angle, a pitch angular velocity, and an acceleration and deceleration speed in the longitudinal direction of a longitudinal behavior sensor 29a and a roll angle, a roll angular velocity; and a lateral acceleration of a lateral behavior sensor 29b are inputted respectively to a car body posture control circuit 30. And operations are performed according to the predetermined program, and driving signals are outputted respectively to a liquid pressure control shock absorbers 5, 5' and 7, 7'. Thus, shock absorbers 5, 7 and 5', 7' are driven in extending and contracting in mutually opposite directions and the change or posture of a car body is amended, and at the same time, the extension and contraction driving is performed further until the posture of a car shifts the opposite direction and the force caused by acceleration and deceleration speed turns to the direction toward the floor surface. By this construction, the actions in longitudinal and lateral directions that passengers feel can be suppressed. |
