PURPOSE:To improve the response of roll control by making a decision that starts the roll control using a steering wheel angular speed value and obtaining the control time using a car speed steering wheel angular speed map or a G sensor map according to the size of the steering wheel angular speed. CONSTITUTION:Suspension units SRL and SRR for right and left front and rear wheels have individually main and sub air spring rooms 11 and 12. Each of the spring rooms 11 and 12 is connected to reserve tank 21 through solenoid valves 221 and 222 for air intake and to the atmosphere through solenoid valves 271 and 272 for air exhaust. In this case, if the steering wheel angular speed obtained from the output of a steering angular sensor 42 exceeds a preset value and if the said angular speed goes below the preset value, a control unit 36 obtains the control time using a car speed steering wheel angular speed map or a G (lateral acceleration) sensor map, respectively. Then, the said solenoid valves 221, 222, 271, and 272 are on-off controlled according to this control time. |
