Title
(JA) 制御システムの異常判定装置および異常判定方法
Abstract
(JA)

モータジェネレータECU(172)の第3CPU(330)は、電圧センサ(180)、電圧センサ(182)、電流センサ(192)、温度センサ(193)、温度センサ(194)、第1CPU(310)、第2CPU(320)および通信回路(350)により伝達された信号が異常であると判定した場合、制御システムが異常であると判定する。第3CPU(330)は、制御システムが異常であると判定した場合、電圧センサ(180)、電圧センサ(182)、電流センサ(192)、温度センサ(193)、温度センサ(194)、第1CPU(310)、第2CPU(320)および通信回路(350)の各々が異常であるか否かを判定する。
