However, conventional devices change the damping force of the shock absorber through electrical control based on the vehicle speed signal from the vehicle speed sensor, thereby increasing wet longitudinal response as neutral or slightly oversteer characteristics when the vehicle speed is low. When the vehicle speed is high, it attempts to improve stability as an understeer characteristic, and it attempts to estimate the behavior of the vehicle depending on the vehicle speed and control it in advance based on that estimate.It is based on the current state of the vehicle. Well then (,
In particular, no consideration was given to the condition of the driving road surface.
There is a problem in that the damping force of the shock absorber is large even on a road surface with continuous unevenness, and the ride comfort becomes poor because the shock absorber tries to move up and down in response to each unevenness.

The amount of rearward displacement of the trailing link 9 becomes constant.
That is, when there is no change in the rearward force F, the flow of oil in the pipe line 17 stops and the pressure difference between the upstream side and the downstream side of the orifice 18 disappears, so the spool valve 144 returns to its initial state. Then, the opening degrees of the ports 142 and 143 are returned to their original values, and the damping force of the horizontal absorber 6 is returned to its initial state. This means that the damping force of the shock absorber 6 is returned to its initial state when the vertical movement of the wheels is eliminated, in other words, when the unevenness of the road surface is eliminated.
