Definitions

  • the rotating electrical machine is connected to the power storage device via a bridge rectifier circuit including a switching element and a diode connected in antiparallel to the switching element, and the control unit When the operation command is not input to the control unit, all the switching elements are turned off.
  • the rotating electrical machine 17 includes a first capacitor 15, a battery 22, and a second capacitor via a bridge circuit configured by the switches Sp and Sn and diodes Dp and Dn connected in antiparallel to the switches Sp and Sn. 23 (power storage device). For this reason, in the state where each switch Sp is turned on, the phase voltage detected by the voltage sensor 42 is affected by the voltage output from the power storage device. For this reason, the second rotation speed calculated based on the phase voltage detected by the voltage sensor 42 and the excitation current detected by the current sensor 43 does not become an accurate rotation speed. As a result, the rotating electrical machine ECU 14 that detects abnormality of the rotation sensor based on the first rotation speed and the second rotation speed cannot accurately detect the abnormality of the rotation sensor. Therefore, in the abnormality detection of FIG. 2, the rotating electrical machine ECU 14 detects the abnormality of the rotational position sensor 44 when all the switches Sp and Sn are turned off.

Abstract

Selon l'invention, un dispositif de détection de défaillance pour détecteur de rotation est équipé: d'une machine électrique rotative (17) qui est entraînée par une force de rotation introduite de l'extérieur pour générer une puissance en courant alternatif, et qui assure la circulation du courant en utilisant une puissance introduite de l'extérieur; un détecteur de rotation (44) qui détecte des informations de rotation représentant la position de rotation et/ou la vitesse de rotation de la machine électrique rotative; et un capteur de tension (42) qui détecte une tension alternative produite par la machine électrique rotative. Ce dispositif de détection de défaillance pour détecteur de rotation est équipé: d'un régulateur (14) qui, sur la base d'une instruction d'exécution introduite de l'extérieur, régule les états de génération de courant alternatif et de circulation du courant de la machine électrique rotative; et une unité de détection de défaillance (14) qui, lorsqu'une instruction d'exécution n'a pas été introduite de l'extérieur dans le régulateur, détecte une défaillance dans le détecteur de rotation sur la base des informations de rotation détectées par le détecteur de rotation, et de la tension alternative détectée par le capteur de tension (42).
