Abstract
If a deceleration exeeds first set value G1 within set time T1 after the brake is depressed, a set amount of fluid is supplied to the fluid spring chamber of each front-wheel suspension unit. If a deceleration exceeds the second set value G2 when set time T1 or more has elapsed upon this operation, a set amount of fluid is exhausted from the fluid spring chamber of each rearwheel suspension unit. With this operation, since braking action for gradually increasing a deceleration is controlled by two stages, uncomfortableness which passangers feel in anti-nose-dive control can be greatly reduced. In addition, control is not performed only by depressing the brake pedal if an acutal deceleration is smaller than first set value G1. Even when a deceleration exceeds first set value G1 upon depression of the brake pedal, if the time when the deceleration exceeds first set value G1 exceeds set time T1, it is determined that a gradual braking operation is performed, so that only control for increasing a damping force is performed.
