Abstract
A control device of a motor-driven 4WD vehicle includes: a 42V alternatordriven by an engineto generate 3-phase AC electricity of 42 volts; a rectifying circuitwhich rectifies the 3-phase AC electricity generated by the 42V alternatorand which supplies DC electricity after rectification to a motor Mwhich drives rear wheels; an inverterwhich lowers the electricity generated by the 42V alternatorinto 14 volts and which converts the lowered AC electricity into DC electricity; and a 14V battery Ewhich is supplied with the electricity obtained by the inverterand which is charged. With this configuration, a generator can function as both a motor generator for charging the 14V battery Eand a motor generator for generating driving electricity of the motor M, and the configuration of the device can be simplified.
