Claim 0:
1. A hybrid driving apparatus for driving a vehicle, the hybrid driving apparatus comprising:
an internal combustion engine that generates a driving force for main driving wheels of the vehicle;
a motive power transmission that transmits the driving force generated by the internal combustion engine to the main driving wheels;
a main driving electric motor as a permanent magnet electric motor that generates a driving force for the main driving wheels;
an accumulator that accumulates electric power for causing the main driving electric motor to work;
sub-driving electric motors as induction electric motors being connected with sub-driving wheels of the vehicle so as to be capable of transmitting motive power to the sub-driving wheels; and
control circuitry configured to control the internal combustion engine, the main driving electric motor, and the sub-driving electric motors and execute an electric motor traveling mode and an internal combustion engine traveling mode, wherein
the driving force generated by the main driving electric motor is transmitted to the main driving wheels via at least a portion of the motive power transmission,
the control circuitry is further configured to cause only the main driving electric motor to generate the driving force in a start of traveling and steady traveling of the vehicle in the electric motor traveling mode and cause the sub-driving electric motors to regenerate electric power in deceleration of the vehicle,
the control circuitry is further configured to cause the internal combustion engine to generate the driving force but not cause the main driving electric motor and the sub-driving electric motors to generate driving forces for driving the vehicle in the internal combustion engine traveling mode, and
the internal combustion engine is a flywheel-less engine that does not include a flywheel, and the control circuitry is further configured to cause the main driving electric motor to generate a torque for maintaining idling of the internal combustion engine in the internal combustion engine traveling mode.
