Embodiment Construction

[0021] exist figure 1 shows schematically an assembly 200 composed of an internal combustion engine 300, a belt-driven starter generator 100 as an electric motor, and a vehicle circuit 30, by means of which a preferred embodiment of the present invention is carried out Explanation.

[0022] The starter generator has a generator part 10 and a rectifier part 20 . The rectifier component is usually operated as a rectifier in generator mode of the machine and as an inverter in motor mode of operation.

[0023] The internal combustion engine 300 is equipped with a pulley 302 on its crankshaft 301 and is connected to the pulley 11 of the starter generator 100 via a drive belt 310 , wherein here a belt tensioning system 320 in the form of a pendulum is provided ( Optional) a drive belt tensioner, which can tension the drive belt 310 during operation regardless of the torque direction. The belt drive with pulley 301 , pulley 11 and belt 11 , which is generally designed as a V-belt ...

Abstract

The present invention relates to a method for starting an internal combustion engine (300) by means of a starter generator (100), the starter generator and the internal combustion engine by means of a transmission pulley having a starter generator (100), the internal combustion engine (300) of the transmission pulley (301) and these transmission belt wheels are connected in the case of transmitting torque (301) of the transmission belt transmission device is connected, wherein the starter generator (100) is thus operated, Such that it is output to the driving torque of the starter generator pulley (11) having a definite driving torque curve, thereby temporarily generating a slave torque on the transmission pulley (301) of the internal combustion engine (300), the slave torque is higher than the driving torque of the starter generator (100) in the case of taking into account the transmission ratio of the transmission belt transmission device.

Description

technical field [0001] The invention relates to a method for starting an internal combustion engine by means of a belt-driven starter generator, as well as to a computing unit and a computer program for carrying out the method. Background technique [0002] An electric machine can be used in a motor vehicle as a so-called starter-generator for, on the one hand, starting the internal combustion engine in motor operation of the electric machine and, on the other hand, generating power for the vehicle in generator operation of the electric machine. Current used in electrical circuits and used to charge motor vehicle batteries. The starter generator can be connected to the internal combustion engine or the crankshaft via a belt drive. [0003] In particular, separately excited AC synchronous motors are suitable for use as belt-driven starter motors (RSG), since their motor-like torque can be adjusted particularly well. The desired torque can be set by corresponding actuation o...
