Embodiment Construction

[0037] exist figure 1 The structure of a motor vehicle 30 according to the present invention is illustrated by way of example. Motor vehicle 30 has an internal combustion engine 3 with an electrified exhaust gas turbocharger 2 . The internal combustion engine 3 also includes an exhaust gas line 4 and a fresh air line 5 . Exhaust gas 6 of internal combustion engine 3 can flow through exhaust gas line 4 . The fresh air path 5 can advantageously be flowed through by charge air 10 which can be supplied to the internal combustion engine 3 . The electrified exhaust gas turbocharger 2 has an exhaust gas turbine 7 which is arranged in the exhaust gas line 4 of the internal combustion engine 3 . The exhaust gas turbine 7 is driven by the exhaust gas 6 of the internal combustion engine 3 during operation of the internal combustion engine 3 . The electrified exhaust gas turbocharger 2 also includes a generator 8 which is drivingly connected to the exhaust gas turbine 7 . Advantageou...

Abstract

The invention relates to a method (1) for controlling an electrified exhaust gas turbocharger (2) of an internal combustion engine (3). The method comprises a measure a) of monitoring a load requirement (16) proposed for the internal combustion engine (3) on the basis of the measure, and a measure b) of activating a turbo mode (18) of the electrified exhaust gas turbocharger (2) if the load requirement (16) monitored in the measure a) exceeds a predetermined threshold value (17).

Description

technical field [0001] The invention relates to a method for controlling an electrified exhaust gas turbocharger of an internal combustion engine and to a motor vehicle comprising an internal combustion engine with an electrified exhaust gas turbocharger, which is designed to carry out such a method according to the invention. Background technique [0002] Exhaust turbochargers have been used for a long time to increase the performance of internal combustion engines. Typically, such an exhaust gas turbocharger comprises: an exhaust gas turbine arranged in the exhaust gas line of the internal combustion engine; and a compressor arranged in the fresh air line of the internal combustion engine. In this case, the exhaust gas energy not used by the internal combustion engine is converted by means of the exhaust gas turbine of the exhaust gas turbocharger and used to drive the compressor. In this case, the compressor is used to compress the charge air flowing through the fresh ai...
