A method for regulating a charge air pressure (p) of an internal combustion engine (2) of a vehicle (1) having an exhaust gas supercharger (4), a fresh gas supply device (5), a vehicle air system having an air treatment system (23) and a compressor (6) that can be charged by the exhaust gas supercharger (4), and an engine controller (31), comprises the following method steps: detecting a torque requirement on the internal combustion engine (2), determining a current charge air pressure (p) and determining a current pressure of the vehicle air system; comparing the current charge air pressure (p) to a target charge air pressure (Psoll) corresponding to said torque requirement, and comparing the determined current pressure of the vehicle air system to a target operating pressure of the vehicle air system; and regulating the charge air pressure (p) by suppressing a supply of compressed air, supplied by the exhaust gas supercharger (4), to the compressor (6) when the determined current charge air pressure (p) is less than the corresponding target charge air pressure (Psoll) and the current pressure of the vehicle air system is greater than or equal to the target operating pressure of the vehicle air system; and a corresponding apparatus.
