摘要： 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.
摘要翻译：如果减速器在制动器被按下之后在设定时间T1内减速第一设定值G1，则将设定量的流体供给到每个前轮悬架单元的流体弹簧室。如果在该操作中经过了设定时间T1以上时减速度超过第二设定值G2，则每个后轮悬架单元的流体弹簧室排出一定量的流体。通过这种操作，由于逐渐增加减速度的制动动作由两个阶段控制，因此可以大大减少防鼻子控制中的通风风味的不适感。此外，如果急停减速度小于第一设定值G1，则不通过按压制动踏板来进行控制。即使当按压制动踏板时减速度超过第一设定值G1时，如果减速度超过第一设定值G1的时间超过设定时间T1，则确定执行逐步制动操作，使得仅仅增加执行阻尼力。

摘要： When vibrations having a period at which pitching tends to occur in a vehicle body is detected, if its amplitude falls out of the range between "H" and "L", a control unit increases the damping force of each suspension unit by using an actuator. In addition, if the amplitude falls out of the range between "HH" and "LL", the control unit supplies a predetermined amount of air to each air spring chamber in response to an upward displacement of vehicle height, and exhausts a predetermined amount of air from each air spring chamber in response to a downward displacement of vehicle height.

摘要： Disclosed is a suspension control apparatus for a vehicle having a plurality of suspension units each disposed between a road wheel and the body of a vehicle for effectively and quickly correcting any deviation of the vehicle height from a normal height level immediately upon finishing of active suspension control operations. Priority is determined for vehicle-height control and various active suspension control operations such as roll control, nose-dive and squat control, and pitching and bouncing control so that normal vehicle-height control is stopped or inhibited during active suspension control operations are being carried out, thereby preventing the traveling attitude of the vehicle from being made unstable. Also, a vehicle-height control determining time interval from the instant when active suspension control operations has been finished until the time when vehicle-height control is restarted is substantially reduced as compared with that required in the case when the vehicle is traveling in a normal attitude without any active suspension control operation, whereby any deviation of the vehicle height from a target height level can be quickly removed to make the actual vehicle height match with a target height level in a very short time immediately after the finishing of the active suspension control operations.

摘要： A vehicle suspension apparatus including suspension units each provided for each wheel and having an air spring chamber is disclosed. When steering wheel is quickly returned toward the center position at the time of a slalom running, it is detected from the steering angular velocity and vehicle velocity that the vehicle body has begun to be returned to a neutral state, and communication control valves are opened before the reaching of the center position, i.e., before the steering angle reaches an insensitive range. Rolling control thus can be improved without delay in the restoration of the position of the vehicle body even at the time of a high speed slalom running, at which time the steering wheel is repeatedly operated quickly.

摘要： A vehicle suspension apparatus comprises a G sensor for detecting lateral acceleration G acting on the vehicle, and a G sensor map for setting the time for supplying/exhausting fluid to and from a fluid spring chamber mounted in each suspension unit in accordance with the lateral acceleration G detected by the G sensor, said lateral acceleration G being higher than a predetermined value. Whether the vehicle is running on a rough road is judged by a rough-road judging routine. When it is judged by the rough-road judging routine that the vehicle is running on a rough road, the non-sensitive area of the G sensor map is widened such that the lateral acceleration G detected by the G sensor is non-sensitive to the G sensor map while the vehicle is running on the rough road, even if the detected lateral acceleration G is somewhat high, thereby preventing the erroneous roll control function.

摘要： A vehicle suspension apparatus including suspension units each provided for each wheel and having an air spring chamber is disclosed, in which rolling control and vehicle height control are done through control of air to and from the air spring chambers. The driving of a reservoir tank for storing compressed air to be supplied to the air spring chambers, is inhibited until the engine operation has been stabilized after the start of the engine preset level. In this way, the problems in the engine lubrication and idling are solved, and the defficiencies of the starting property of the engine are overcome.
