ELECTRIC MACHINE INTEGRATED WITH A GEAR-BOX OF AUTOMOTIVE INTERNAL COMBUSTION ENGINES AND CONTROL SYSTEM THEREFOR

摘要

A drive aggregate for motor vehicles has an internal combustion engine (12) and a gearbox (18) which acts on the driving wheels of the motor vehicle. A gearbox input shaft (20) can be coupled to an output shaft (14) of the internal combustion engine. An electric machine (32) which can be coupled to the gearbox (18) by an intermediate gearbox (34) acts as a starter motor for starting the internal combustion engine (12) and as a generator for supplying the motor vehicle on-board network. In addition, the electric machine should ensure the synchronisation of the gearbox during gear shifts, together with at least one electronically controlled clutch and a flywheel mass (24). For the generator to always supply sufficient electric power, from idle running up to the nominal speed of rotation of the internal combustion engine, its speed of rotation is regulated depending on the engine speed of rotation by changing the transmission ratio of the intermediate gearbox.
