<p>A driving unit for a vehicle includes a transmission (12), a motor generator (20) and a centrifugal release mechanism (25). The transmission (12) is employed for transmitting a driving torque outputted from an engine (10) to an output shaft (16) operatively connected to a plurality of driving wheels. The motor generator (20) is connected to the output shaft (16) via a force transmitting mechanism (17). The motor generator (20) functions as a motor for driving the output shaft (16) in cooperation with the engine (10) when supplied with electric current and functions as a generator when driven by the output shaft (16). The centrifugal release mechanism (25) is provided at the force transmitting mechanism (17). The centrifugal release mechanism (25) interrupts a force transmission between the output shaft (16) and the motor generator (20) in a predetermined driving state of the vehicle in which a running resistance applied to the driving wheels exceeds a driving force of the motor generator (20) applied to the driving wheels.</p> |
