Abstract
A vehicle driving system 1 includes a first motor/generator M/G1 which is mechanically connected to either of front wheels Wf and rear wheels Wr of a vehicle, a second motor/generator M/G2 which is electrically connected with the first motor/generator M/G1, and a flywheel FW which is mechanically connected with the second motor/generator M/G2 and which stores kinetic energy. The second motor/generator M/G2 is mechanically connected to the other of the front wheels Wf and the rear wheels Wr of the vehicle.
Claims32
A vehicle driving system including:
- a first motor/generator which is mechanically connected with a first wheel of a vehicle;
- a second motor/generator which is electrically connected with the first motor/generator and which is mechanically connected with a second wheel of the vehicle;
- a kinetic energy storing device which is mechanically connected with the second motor/generator and which stores kinetic energy;
- a first engaging/disengaging unit which is provided on a power transmission path between the second motor/generator and the kinetic energy storing device and which engages or disengages a side of the second motor/generator and a side of the kinetic energy storing device by being applied or released;
- a second engaging/disengaging unit which is provided on a power transmission path between the second motor/generator and the second wheel and which engages or disengages a side of the second motor/generator and a side of the second wheel by being applied or released;
- and
- an electric energy storing device which is electrically connected with the first motor/generator,
- wherein, when the first motor/generator is driven for regeneration by receiving power from the first wheel, the first engaging/disengaging unit is applied, the second motor/generator is driven for power, and the second engaging/disengaging unit is released and the second motor/generator and the second wheel are disengaged,
- when the energy stored in the kinetic energy storing device is of a predetermined level or higher, the first engaging/disengaging unit is released, the second engaging/disengaging unit is applied, and the second motor/generator is driven for regeneration,
- such that the first engaging/disengaging unit and the second engaging/disengaging unit are controlled so as not to be applied at the same time.
