PROBLEM TO BE SOLVED: To shorten time required for vehicle height adjustment when cargo is loaded, and to improve efficiency of loading work.SOLUTION: A combination vehicle 1 which has an air bellows 11 forming an air suspension, and performs control so as to keep vehicle height constant by adjusting air pressure in the air bellows 11 includes a controller 18 for, when no cargo is loaded, estimating increment in a load to be applied on the air bellows 11 when cargo of predetermined weight is loaded, restricting vehicle height so that the vehicle height is not higher than vehicle height when the increment in a load is estimated, and adjusting air pressure in the air bellows so that the estimated increment in a load can be supported by the air pressure, while restricting the vehicle height. The controller 18 removes the restriction on the vehicle height when cargo is loaded. |
