Method for controlling an air suspension system (2, 2') of a vehicle, comprising the following method steps: - providing the vehicle comprising the air suspension system (2, 2'), the vehicle comprising the following: - an air-suspended front axle and at least one air-suspended rear axle, - on both sides of each of the air-suspended vehicle axles (FA, RA), air springs (4, 6, 8, 10) arranged between a chassis component and a vehicle frame, each with compressed-air-filled bellows (5, 7, 9, 11), - a valve arrangement having - shut-off valves (14, 20, 38, 44) associated with each of the air springs (4, 6, 8, 10) and - combined inlet/outlet valves (24, 48; 24', 48'), which are connected in groups upstream of the shut-off valves, and - a sensor arrangement, the sensor arrangement having - displacement sensors (66, 70, 74, 78) arranged close to each of the air springs (4, 6, 8, 10) for measuring the relevant chassis height (h FAL, h FAR, h RAL, h RAR), and - pressure sensors (82, 86, 90, 94) connected to the bellows (5, 7, 9, 11) of each of the air springs (4, 6, 8, 10) for measuring the relevant bellows pressure (p FAL, p FAR, p RAL, p RAR), characterized in that - the bellows pressures (p FAL, p FAR) of the air springs (4, 6) on the front axle are compared with one another, a higher bellows pressure (p FAR; p FAL) and a lower bellows pressure(p FAR; p FAL) being determined from the bellows pressures (p FAL, p FAR) and - if a determined bellows pressure difference (dp FA = P FAL - P FAR) of the bellows pressures (p FAL, p FAR) of the air springs (4, 6) of the front axle has exceeded (| dp FA | = | p FAL - p FAR | > | Δp Tοl |) a predetermined differential pressure tolerance (Δp Tol), compensation of the bellows pressure difference (dp FA) on the front axle is carried out by - the air spring (4; 6) of the front axle having the higher bellows pressure (p FAL; p FAR) and the air spring of the rear axle arranged diagonally opposite thereto being ventilated and - the air spring (6; 4) of the front axle having the lower bellows pressure (p FAR; p FAL) and the air spring of the rear axle arranged diagonally opposite thereto being ventilated. - providing the vehicle comprising the air suspension system (2, 2'), the vehicle comprising the following: - an air-suspended front axle and at least one air-suspended rear axle, - on both sides of each of the air-suspended vehicle axles (FA, RA), air springs (4, 6, 8, 10) arranged between a chassis component and a vehicle frame, each with compressed-air-filled bellows (5, 7, 9, 11), - a valve arrangement having - shut-off valves (14, 20, 38, 44) associated with each of the air springs (4, 6, 8, 10) and - combined inlet/outlet valves (24, 48; 24', 48'), which are connected in groups upstream of the shut-off valves, and - a sensor arrangement, the sensor arrangement having - displacement sensors (66, 70, 74, 78) arranged close to each of the air springs (4, 6, 8, 10) for measuring the relevant chassis height (h FAL, h FAR, h RAL, h RAR), and - pressure sensors (82, 86, 90, 94) connected to the bellows (5, 7, 9, 11) of each of the air springs (4, 6, 8, 10) for measuring the relevant bellows pressure (p FAL, p FAR, p RAL, p RAR), - the bellows pressures (p FAL, p FAR) of the air springs (4, 6) on the front axle are compared with one another, a higher bellows pressure (p FAR; p FAL) and a lower bellows pressure(p FAR; p FAL) being determined from the bellows pressures (p FAL, p FAR) and - if a determined bellows pressure difference (dp FA = P FAL - P FAR) of the bellows pressures (p FAL, p FAR) of the air springs (4, 6) of the front axle has exceeded (| dp FA | = | p FAL - p FAR | > | Δp Tοl |) a predetermined differential pressure tolerance (Δp Tol), compensation of the bellows pressure difference (dp FA) on the front axle is carried out by - the air spring (4; 6) of the front axle having the higher bellows pressure (p FAL; p FAR) and the air spring of the rear axle arranged diagonally opposite thereto being ventilated and - the air spring (6; 4) of the front axle having the lower bellows pressure (p FAR; p FAL) and the air spring of the rear axle arranged diagonally opposite thereto being ventilated.
