Abstract
In order to increase the operating reliability by means of simple measures in a method for operating a supercharged internal combustion engine which has two exhaust-gas turbochargers arranged in parallel, in each case only one exhaust-gas turbocharger is actively put into operation, the actual value of a characteristic quantity is measured and is compared with a predeterminable desired value, and, in the event of an inadmissible deviation of the actual value from the desired value, a change-over is made between the exhaust-gas turbochargers by means of the control signal.
