Title:
電気式スーパーチャージャを作動させるための、動力伝達装置におけるモータ/発電機を使用する車両推進システム
Document Type and Number:
Japanese Patent JP2008543626
Kind Code:
A
Abstract:
An automotive propulsion system includes an internal combustion engine (6) with an inlet air duct (66) and an output shaft (10), which is connected to the input shaft of a transmission system (58) of continuously variable transmission ratio. The transmission system comprises a differential gearset comprising at least three shafts (10, 12), two of which constitute the input shaft and output shaft, respectively and all of which carry at least one gear wheel in mesh with at least one gear wheel carried by one of the other shafts. The transmission system also includes two electric motor/generators (42, 46; 50, 52), the rotors (42, 50) of which are connected to respective shafts and the electrical connections (43, 45) of which are connected to a controller (62) arranged to control the flow of electrical power between them. The propulsion system also includes an electrically driven supercharger (60) communicating with the inlet duct (66) and connected to the controller (62). The controller (62) is programmed so that, at least at speeds of the transmission input shaft (10) and/or transmission output shaft (12) lower than a predetermined threshold value, it is selectively able to direct electrical power from at least one of the motor/generators, which is operating as a generator, to the electric motor of the supercharger (60) so as to increase or decrease the pressure in the inlet duct (66) and thus also the torque applied to the output shaft (12) of the engine.
