PURPOSE:To check the occurrence of a dive promptly as well as to prevent a car attitude from yielding, by throttling both solenoid throttle valves for an air spring and a shock absorber when the output of a sensor, which detects such a driving state as causing a car body to dive, goes beyond the reference value. CONSTITUTION:As a sensor as detecting such a driving state as causing a car body to largely tilt over, each of car-level sensors 15 is installed in both front and rear wheels, while detecting signals hF and hR out of each car-level sensor 15 are impressed on an operation circuit 32. At the operation circuit 32, a difference h between both signals is found, then the differential signal given is added to a control circuit 33 and hereat compared with a reference value DELTAho set by a dive reference signal setter 31. And, in time of being DELTAh>DELTAho, each of solenoid throttle valves 4 and 8 is throttled while in time of being DELTAh<DELTAho, they are controlled so as to fully open both these valves 4 and 8. The solenoid throttle valve 8 is installed in a passage interposingly between a spring body 7 of an air spring 5 and an air tank 6 while the solenoid throttle valve 4 is installed in a passage interposingly between both end liquid chambers of a shock absorber (unillustrated herein). |
