摘要： An apparatus and method for controlling an air suspension of a vehicle are disclosed. The apparatus includes a compressor configured to supply compressed air, a reservoir configured to store compressed air supplied from the compressor and to supply the stored compressed air to the air suspension during vehicle height control, a road information provider configured to provide road state information of a road in front of the vehicle during travel of the vehicle, and a controller configured to determine a vehicle height control position of the air suspension based on the road state information and to operate the compressor before the vehicle arrives at the determined vehicle height control position, thereby filling the reservoir with the compressed air such that an internal pressure of the reservoir reaches at least a predetermined reference pressure.

摘要： An apparatus for estimating vehicle weight using a vehicle height adjusting device is provided. The apparatus includes a vehicle height adjusting device that raises or lowers four positions of front left (FL) and right (FR) sides and rear left (RL) and right (RR) sides of a vehicle body, respectively. A vehicle height controller operates the vehicle height adjusting device to raise or lower the FL and FR sides and the RL and RR sides of the vehicle body. A weight estimating unit measures time required for raising or lowering the vehicle body or operating speed of the vehicle body and calculates an expected vehicle weight value by comparing the time required or the operating speed with a preset reference data.

摘要： A device for controlling traveling of a vehicle is provided. The device includes a sensor that obtains vehicle traveling information, a navigation that obtains vehicle position information, and a controller that determines whether the vehicle has entered a building based on the vehicle traveling information and the vehicle position information. The controller calculates a traveling control amount based on the determination result. Accordingly, the device actively adjusts a vehicle height even when the vehicle enters the building and travels on a slope in the building preventing damage to a lower portion of the vehicle.

摘要： A vehicle height control apparatus includes an information acquisition device that acquires pressure data on a pressure inside an air tank storing compressed air and obstacle data on an obstacle in front of a vehicle, and a controller that calculates a target vehicle height based on the obstacle data, calculates a required distance required to reach the target vehicle height based on the pressure of the compressed air inside the air tank, and determines a vehicle height control timing, resolving a problem that the vehicle height is unnecessarily quickly controlled compared to the position of the obstacle, or is controlled after the vehicle passes through the obstacle to reduce the ride comfort.
