A hybrid drive system comprising: an internal combustion engine having a first output shaft; an electric motor having a second output shaft coupled to the first output shaft, the motor being capable of operating in a drive mode to drive the second output shaft and in a regeneration mode to generate electricity from the motion of the second output shaft; a gearbox having an input shaft coupled to the first and second output shafts and an output shaft coupleable to the input shaft in any of two or more gear ratios; a control unit arranged to control the electric motor during the changing of the gearbox from one gear ratio to another so as to alter the speed of the input shaft so as to match that of the output shaft for the said other gear ratio. |
