ACTIVE TYPE SUSPENSION DEVICE
Document Type and Number:
Japanese Patent JPS63235112
Kind Code:
A
Abstract:
PURPOSE:To improve riding comfort by adjusting gains separately for forming instruction signals to the hydraulic cylinders of front and rear wheels in such a way as to remove a difference in pitching variation between the front and rear wheels depending upon acceleration and deceleration information in the lengthwise direction of a vehicle. CONSTITUTION:A lengthwise acceleration signal gx is inputted from a lengthwise acceleration sensor 24 to a controller 22. This controller 22 comprises an instruction signal formation means for left front and rear right pressure control valves 20FL and 20RR, and a gain adjusting means for adjusting the value of the instruction signal separately between front and rear wheels on the basis of the inputted acceleration signal gx. And the gain adjusting means adjust the gains of an instruction value information means separately so that the pitching magnitudes of the front and rear wheels in acceleration and deceleration modes will give no difference. It follows, therefore, the pitching magnitudes of the front and rear wheels give no difference according to an instruction signal outputted from the controller 22, thereby enabling the improvement of riding comfort.
