Problems solved by technology

[0006] Starting from the solutions known from the above-mentioned background art, a conflicting goal is usually obtained, because although the pre-excitation of the electric machine can achieve a gentle start of the internal combustion engine, but after the start request and the establishment of the starting requirements for the internal combustion engine The waiting time between torques is longer

Embodiment Construction

[0025] The present invention is based on figure 1 and 2 The system shown in , where like elements have the same reference numerals.

[0026] figure 1 A system 200 consisting of an internal combustion engine 300 , a belt-driven starter generator 100 (as electric machine) and an on-board electrical system 30 is shown, by means of which a preferred embodiment of the invention will be explained (see in particular FIG. 5 ).

[0027] The internal combustion engine 300 is connected to the starter generator 100 via a belt 310 , in which a belt tensioner designed as an oscillating tensioning system 320 is provided, which can tension the belt 310 during operation independently of the direction of the torque. The belt 310 provides therein an elastic coupling between the starter generator 100 , the crankshaft of the internal combustion engine 300 and possibly other units, such as an air conditioner compressor for an air conditioner not shown.

Abstract

The invention relates to a method for improving a starting process of an internal combustion engine (300) by means of a belt-driven starter generator (100), which has a stator winding (11) and a rotorwinding (12), wherein the starter generator (100) for generating a starting torque is operated in such a way that, immediately after a start request (S) of the starter generator (100), the stator winding (11) and the rotor winding (12) are substantially simultaneously supplied with current. The invention further relates to a computing unit which is designed to carry out the method.

Description

[0001] The invention relates to a method for improving the starting process of an internal combustion engine, in particular an engine via a belt-driven starter generator, and a computing unit for implementing the method. Background technique [0002] The electric machine can be used in a motor vehicle as a so-called starter generator in order to start the internal combustion engine on the one hand in motor operation of the electric machine and, on the other hand, to generate electricity for the on-board electrical system and for The current to charge the vehicle battery. The starter generator can be connected to the internal combustion engine or to the crankshaft via a belt drive. [0003] In particular, separately excited motors, especially three-phase synchronous motors, are suitable for use as belt-driven starter generators (RSG), since their motor torque can be controlled particularly well. The desired torque can be adjusted by correspondingly manipulating the rotor windi...
