Method for operating a vehicle and for controlling a pneumatic suspension system for the vehicle, wherein the pneumatic suspension system in each case has a changeover valve for the pneumatic springs of a vehicle axle or of a plurality of adjacent tandem axles, and a shutoff valve for the pneumatic spring of each vehicle wheel of the vehicle axle or for the pneumatic springs of each vehicle side of the tandem axles, and in which the relevant changeover valve and the shutoff valves are structurally combined in a valve block arranged remotely from the pneumatic springs , wherein the pneumatic suspension system, for measuring the bellows pressures in the spring bellows of the pneumatic springs , in each case has a pressure sensor , which sensors are arranged in or on the valve block , wherein the pressure sensors are each connected, at an outlet of the associated shutoff valve , to the connection line of the spring bellows of the associated pneumatic spring or the spring bellows of the associated pneumatic springs, and in which the bellows pressure (p B ) in the spring bellows of the pneumatic springs can be set exactly to a target pressure (p B_2 ) by means of measured values of the pressure sensors , wherein the method comprises the following method steps: a) determining in each case at least one bellows pressure-time characteristic curve (p B /p V (t)), which is standardized with the value of a supply pressure (pv) in a storage tank for compressed air, for air admission to and air release from the spring bellows of a pneumatic spring or the spring bellows of a plurality of pneumatic springs, b) measuring via a sensor the current bellows pressure (p B_1 ) in the spring bellows of the pneumatic spring or in the spring bellows of the pneumatic springs as well as the current supply pressure (p V_1 ) immediately before air admission thereto or air release therefrom, c) determining, from the standardized bellows pressure-time characteristic curve (p B /p V (t)) for air admission or air release, the opening duration (Δt 0 ) for the corresponding shutoff valve using the ratio of the measured bellows pressure (p B_1 ) to the measured supply pressure (p V_1 ) and the ratio of the provided target pressure (p B_2 ) to the measured supply pressure (p V_1 ), d) opening the corresponding shutoff valve for the determined opening duration (Δt o ) in order to set the provided target pressure (p B_2 ). a) determining in each case at least one bellows pressure-time characteristic curve (p B /p V (t)), which is standardized with the value of a supply pressure (pv) in a storage tank for compressed air, for air admission to and air release from the spring bellows of a pneumatic spring or the spring bellows of a plurality of pneumatic springs, b) measuring via a sensor the current bellows pressure (p B_1 ) in the spring bellows of the pneumatic spring or in the spring bellows of the pneumatic springs as well as the current supply pressure (p V_1 ) immediately before air admission thereto or air release therefrom, c) determining, from the standardized bellows pressure-time characteristic curve (p B /p V (t)) for air admission or air release, the opening duration (Δt 0 ) for the corresponding shutoff valve using the ratio of the measured bellows pressure (p B_1 ) to the measured supply pressure (p V_1 ) and the ratio of the provided target pressure (p B_2 ) to the measured supply pressure (p V_1 ), d) opening the corresponding shutoff valve for the determined opening duration (Δt o ) in order to set the provided target pressure (p B_2 ). <EOS>
