Abstract:
A transmission system for a hybrid vehicle is disclosed. The system comprises a primary input shaft (16) for receiving drive from a primary vehicle drive motor (21), such as an internal combustion engine. A secondary input shaft (42) receives drive from a secondary vehicle drive motor (34), such as an electric motor. An output shaft (14) of the system is connected to drive a final drive unit (12). A multi-speed gearbox (10) is provided to connect the primary input shaft (16) to the output shaft (14) at one of a plurality of gear ratios. There is provided input selection means (48) which, in a first configuration, connects the secondary input shaft (42) to drive the output shaft (14) and, in a second configuration, connects the secondary input shaft (42) to drive the primary input shaft (16). A clutch (21a) may be provided that can selectively connect or disconnect drive between the primary drive motor (21) and the gearbox (10).
