ELECTRONICALLY CONTROLLED SUSPENSION DEVICE

摘要

PURPOSE:To prevent a car body from being shocked by constituting a unit so that the body attitude may be restored by opening the air discharge control valves for front and rear wheels when accelerator opening degree varies more than specified values varied with time lapse, and by adjusting the body height when accelerator shutting degree varies less than specified values varied with time lapse. CONSTITUTION:The opening degree signals from an accelerator opening degree sensor 49 is input in a controller 36. The controller 36 determines the time lapse variation of the accelerator opening degree based on these signals. If the determined value is more than the specified value, a front wheel air discharge solenoid valve 273 and 274 and a rear wheel air supply solenoid valve 221 and 222 are opened by the controller 36 to lower the body front. If the determined value of the time lapse variation of the accelerator shutting degree is more than the specified value, front wheel air supply solenoid valves and rear wheel air discharge solenoid valves open. If the value is less than the specified value, the body attitude is restored little by little by means of car body height adjustment. This constitution causes the car body to be prevented from being shocked.
