Abstract
Abstract A control apparatus which detects vertical and/or lateral acceleration of a vehicle body so as to control characteristic of a support unit for supporting the vehicle body, in other words, a damping force and/or a spring constant of a suspension, or torsion quantity of a stabilizer, on the basis of quantity of acceleration or a differentiated value thereof and vibration cycle period of the acceleration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
A control apparatus of a support unit for supporting a vehicle body which controls a characteristic of said support unit, said control apparatus comprising: detecting means for detecting acceleration of said vehicle body; change-over means for changing over the characteristic of said support unit into a plurality of states; and control means for controlling said change-over means on the basis of a quantity and a vibration cycle period of the acceleration detected by said detecting means, wherein said support unit is a suspension and a stabilizer, said characteristic includes at least one of a damping force and a spring constant of said suspension, and a torsion quantity of said stabilizer, and when said quantity and said vibration cycle period of said acceleration detected by said detecting means is no less than a predetermined value, said control means controls said change-over means such that the characteristic of said support unit is set to a first state, said characteristic being maintained at said first state in accordance with to a length of said vibration period.
Claim 2
Dependent Claim
173 words
A control apparatus of a support unit for supporting a vehicle body which controls a characteristic of said support unit, said control apparatus comprising: detecting means for detecting acceleration of said vehicle body; change-over means for changing over the characteristic of said support unit into a plurality of states; and control means for controlling said change-over means on the basis of a quantity and a vibration cycle period of the acceleration detected by said detecting means, wherein said support unit is a suspension and a stabilizer, said characteristic includes at least one of a damping force and a spring constant of said suspension, and a torsion quantity of said stabilizer, and when said quantity and said vibration cycle period of said acceleration detected by said detecting means is no less than a predetermined value, said control means controls said change-over means such that the characteristic of said support unit is set to a first state, said characteristic being maintained at said first state in accordance with to a length of said vibration period.
