Abstract: A vehicle has a device for setting an open position of a tailgate, which can be pivoted upwards and, after an opening command to a first control unit, can be adjusted into a predefined open position via an adjusting device. The vehicle has a device for setting a predefined vehicle height, which device includes a second control unit for actuating an active wheel suspension system. Lowering of the vehicle height is performed at the same time as the opening of the tailgate, by way of a communications link between the first control unit and the second control unit and by way of corresponding programming of at least one of the two control units. The simultaneous opening of the tailgate and lowering of the vehicle height are prevented if a blocking command for this function is present in one of the two control units.

Abstract: A level control system for an omnibus, especially a low-loading omnibus, having an omnibus body supported on axles and wheel suspension, is comprised of a compressed air system that is self-contained for each axle. The following vertical adjustments are possible: during a stop of the omnibus at a bus stop, the omnibus body is pivoted about a longitudinal median floor level axis for lowering the omnibus body at a passenger boarding side and the opposite side is raised by internally pumping the compressed air from the pneumatic springs of the boarding side to the pneumatic springs on the opposite side at each axle. After the completion of the stop at the bus stop, the compressed air is returned to the pneumatic springs on the boarding side so that the omnibus resumes its normal position. In this manner, the compressed air is kept in a self-contained system and is not lost to the atmosphere. Accordingly, there is no need to provide further compressed air to the system, thus reducing the amount of energy required for operating such a system; the power necessary for the internal pumping or transfer of the compressed air is small in comparison.

Abstract: In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to vehicle wheels. Each actuator is adapted to increase or decrease vehicle height in response to the hydraulic pressure within its working fluid chamber. The hydraulic pressures within the working fluid chambers are controlled to their desired pressure by associated pressure control devices. A desired pressure computing device is further provided. The computing device calculates the actual values of roll, pitch, heave and warp of a vehicle body from the vehicle heights detected by detecting devices and calculates the differences between the actual values and the associated values of roll, pitch, heave and warp determined by a desired attitude of the vehicle body to compute the desired pressures for the actuators. The degrees of the roll and/or pitch differences are set to be higher than that of the warp difference in contributing to the determination of the desired pressures.

Abstract: A vehicle-height adjusting system includes: vehicle-height adjusting actuators each for adjusting a vehicle height for a corresponding one of wheels; a pressure medium supplier for supplying a pressure medium from a tank to each of the vehicle-height adjusting actuators; and a vehicle height adjuster for adjusting the vehicle height for each wheel. The vehicle-height adjusting actuators include a left vehicle-height adjusting actuator and a right vehicle-height adjusting actuator. The vehicle height adjuster includes a supply amount controller configured to control the pressure medium supplier such that substantially the same amount of the pressure medium is to be supplied from the tank to the left vehicle-height adjusting actuator and the right vehicle-height adjusting actuator, when at least one of the wheels is in contact with an uneven road surface.
