Abstract
When a rotational difference is generated between a left driving wheel and a right driving wheel, by controlling the frequency f0 of alternating currents to be fed to stator windings of first and second induction machines by a shared inverter, torque distribution to the left driving wheel and the right driving wheel is controlled.
Claims14
A driving power distribution device that adjusts torque distribution to a first drive shaft and a second drive shaft, the device comprising:
- a first induction machine that transmits a torque to the first drive shaft;
- a second induction machine that transmits a torque to the second drive shaft;
- and
- a shared power conversion system that applies common alternating currents to the first induction machine and the second induction machine, wherein
- a frequency of the common alternating currents is set based on:
- a rotational speed and a target torque value of the first induction machine, and separately a rotational speed and a target torque value of the second induction machine.
