Patent ID: 7959534

Claim:
A hybrid driving apparatus, comprising: a power source; a generator; a power distributing mechanism distributing at least a part of power from said power source to said generator and distributing remaining part to a rotation output shaft; and a first transmission mechanism arranged in a power transmission path from said rotation output shaft to driving wheels, said first transmission mechanism being capable of selecting a normal transmission stage used for normal traveling and at least one low-speed side transmission stage set to a transmission gear ratio larger than said normal transmission stage, in accordance with a driver's operation; an electric motor connected to said power transmission path between said power distributing mechanism and said first transmission mechanism, generating driving force using electric power; a vehicle speed obtaining unit; and a controller controlling operations of said power source, said generator and said electric motor; wherein when said low-speed side transmission stage is selected in said first transmission mechanism, said controller executes a control operation such that the vehicle speed does not exceed a limit vehicle speed determined in advance in correspondence with transmission gear ratio of said low-speed side transmission stage.
