    摘要: There is provided a method of operating a hybrid-vehicle drive system in which an internal combustion engine (1), a first electric motor (8) and a second electric motor (12) are combined to provide a driving source for a hybrid vehicle, wherein an output shaft (2) of the internal combustion engine (1) and the first electric motor (8) are connected via a power distribution mechanism (3) to a wheel drive shaft (11), a transmission (100) having a plurality of gear positions is provided on the wheel drive shaft (11), and the wheel drive shaft (11) is connected via a connecting portion (16) to the second electric motor (12). The method comprises steps of: setting a gear position of the transmission (100) to a first gear position having a predetermined high-speed gear ratio as a first gear ratio, and maintaining the transmission in the first gear position irrespective of changes in a vehicle speed, as long as the hybrid-vehicle drive system is able to provide a required value of a torque at vehicle axles while the internal combustion engine (1) is operated at a high fuel efficiency.
