Abstract
The invention is directed to a method and an arrangement for controlling the charging pressure of an exhaust-gas turbocharger () wherein a charging pressure actual value (pvdkds) is tracked to a charging pressure desired value (plsoll). The charging pressure of the exhaust-gas turbocharger () is controlled in dependence upon a characteristic variable of an electric auxiliary charger (). The electric auxiliary charger () coacts with the exhaust-gas turbocharger () for compressing the inducted air. In this way, an unnecessary opening of a bypass valve of the exhaust-gas turbocharger () is avoided.
