CONTROLLER AND CONTROL METHOD OF MOTOR DRIVEN 4WD VEHICLE

PROBLEM TO BE SOLVED: To provide a controller and a control method of a motor driven 4WD vehicle in which an AC motor for driving rear wheels can be driven positively even when the power being generated from a 42V alternator is low. SOLUTION: The controller of the motor driven 4WD vehicle comprises...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a controller and a control method of a motor driven 4WD vehicle in which an AC motor for driving rear wheels can be driven positively even when the power being generated from a 42V alternator is low. SOLUTION: The controller of the motor driven 4WD vehicle comprises a 42V alternator 2 being driven through an engine 1 to generate a three-phase AC power, a front step-up/down inverter 3 for rectifying the three-phase AC power generated from the 42V alternator 2 and supplying a DC power produced through rectification to the neutral of an AC motor M1, and a rear step-up/down inverter 13 for converting the DC power rectified by the front step-up/down inverter 3 into a three-phase AC power of desired voltage. The AC motor M1 is rotary driven by applying the three-phase AC power stepped up by the rear step-up/down inverter 13 to the AC motor M1. COPYRIGHT: (C)2005,JPO&NCIPI
