摘要： A vehicle-height control system includes: a fluid supply and discharge device including a compressor configured to suck fluid, and a tank configured to supply the fluid; an actuator-side passage connected to the fluid supply and discharge device; a vehicle-height control actuator provided for a wheel and connected to the actuator-side passage via a vehicle-height control valve; and a vehicle height controller configured to control a vehicle height for the wheel by controlling the fluid supply and discharge device and the vehicle-height control valve to control supply and discharge of the fluid in the vehicle-height control actuator. The vehicle height controller includes a start controller configured to open the vehicle-height control valve after establishing communication between the actuator-side passage and at least one of the tank and the compressor in a state in which the vehicle-height control valve is closed at a start of control of the vehicle height.

摘要： A suspension system capable of improving maneuverability and stability, the suspension system including a force generation mechanism and a controller. The controller, which controls each of shock absorbers, includes a main control calculation unit, a longitudinal force reaction force calculation unit, a lateral force reaction force calculation unit, an addition unit, and a suspension reaction force consideration unit. The controller subtracts an output from a vertical force calculation unit including the longitudinal force reaction force calculation unit, the lateral force reaction force calculation unit, and the addition unit from an output from the main control calculation unit by the suspension reaction force consideration unit, thereby succeeding in calculating a vertical force applied between a vehicle body and each wheel as a value in consistency with an actual behavior of a vehicle.

摘要： Disclosed is a level control system in which the operational readiness of the compressor (2) is tested by connecting the pressure sensor (10) to the output (6) of the compressor (2) via a compressed-air sensor line (8). All other compressed-air lines that are connected to the output (6) of the compressor (2) are locked by shutting directional control valves (201 to 20d and 30). The compressor (2) is then switched on and it is tested how rapidly the pressure increases on the pressure sensor (10). If the increase per interval exceeds a defined threshold value, the compressor is operationally ready.

摘要： An adaptive suspension system for a motor vehicle varies suspension parameters in response to steering input. The system includes a sensor to measure changes in the power assist steering mechanism that indicate a change in vehicle direction and a shock variable suspension member changed in response to a change in vehicle direction. The sensor measures pressure changes in the power assist steering system such that the suspension system is optimized to accommodate specific vehicle maneuvering. In another embodiment, the variable suspension member is in hydraulic communication with the hydraulic circuit of the power assist steering mechanism such that pressure changes caused by steering input triggers changes in the suspension system to accommodate vehicle maneuvering.
