<P>PROBLEM TO BE SOLVED: To further extend a save travelling distance when abnormality occurs in one of two rotary electrical machines in a rotary electrical machine control system. <P>SOLUTION: The rotary electrical machine control system 10 includes: a first resolver 22, a second resolver 24, two R/D converters 72, 74 for converting detection results of two resolvers to rotation angle information, a selector unit 70 for each selecting each connection destination of two R/D converters 72, 74 between the first resolver 22 or the second resolver 24, and a CPU 66 for continuing vehicle cruise by controlling an operation of a first rotary electric machine 12 or a second rotary electric machine 14 using a remaining normal R/D converter when any one of the two R/D converters are failed and for alternately switching modes between a control mode of cruising by an engine 6 and a control mode of cruising by the second rotary electric machine 14 in response to a charged state of a high voltage power source unit 40. <P>COPYRIGHT: (C)2010,JPO&INPIT |
