A method for controlling the level of an air-suspended motor vehicle includes determining, by a sensor system, at least one of the speed of travel or the actuation state of a parking brake, measuring, if at least one of the speed of travel has undershot a minimum speed of travelor the parking brake has been actuated, the actual level in the region of each air spring bellows, comparing the measured values for the actual level with the predetermined setpoint level, determining an actual level value of an air spring bellows having the greatest deviation from the setpoint level, and expanding, for the air spring bellows having an actual level having the greatest deviation from the setpoint level, the tolerance band by at least one of increasing the upper tolerance limit thereof to a corrected upper tolerance limit or lowering the lower tolerance limit thereof to a corrected lower tolerance limit.

A bus is provided, including: a frame assembly including a front frame, a rear frame and a hinge turntable therebetween; carriages including a front carriage having a front carriage body and a front carriage floor, and a rear carriage having a rear carriage body and a rear carriage floor; a front axle and a middle axle disposed at a bottom of the front frame; a rear axle disposed at a bottom of the rear frame; a first group of battery packs including a first battery pack disposed within a rear cabin in the rear of the rear carriage body and a second battery pack disposed on the rear frame; a second group of battery packs disposed on upper surfaces of top roof of the front and rear carriage bodies; a third group of battery packs disposed on the front carriage floor and between the front axle and the hinge turntable.

A method for monitoring a vehicle, the vehicle comprising a control unit and an air suspension system, the air suspension system comprising pressure sensors configured to provide data representative of operating pressures of the air suspension system. To improve the monitoring of the vehicle, the method comprises determining a centre of mass of the vehicle by the control unit on the basis of data provided by the pressure sensors at least once during operation of the vehicle.

The invention relates to a method for controlling a flow from a source of pressurized air to an air bag of a pneumatic suspension arrangement in a vehicle. The method comprises obtaining a set of vehicle condition signals comprising at least two vehicle condition signals, each vehicle condition signal being indicative of an individual current condition associated with said vehicle. The method further comprises, on the basis of said set of vehicle condition signals, determining whether or not there is a need to supply the air bag with air from the source of pressurized air. The method further comprises, in response to determining that there is not a need to supply the air bag with air from the source of pressurized air, preventing pressurized air to be fed from said source of pressurized air to said air bag.
