ROTATION ANGLE DETECTING DEVICE AND ELECTRIC TYPE POWER STEERING DEVICE

摘要: PROBLEM TO BE SOLVED: To provide an electric type power steering device capable of detecting the earth fault a resolver without error. SOLUTION: The difference between minimum output potential Vout Min first differential amplifier OP1 in case non-earth which may be produced by variations values resistance R1, second R2, third R3 and fourth R4 DC Rdc resolver, highest Max is set so that becomes more than predetermined margin for preventing error detection at side CPU 62. Thereby, can detected based on OP1. COPYRIGHT: (C)2006,JPO&NCIPI
