  • Abnormality detection apparatus and abnormality detection method
    Patent number: 9680404
    Abstract: An abnormality detection apparatus configured to detect an abnormality of an inverter provided to control a motor generator when a value obtained by performing a predetermined process for a current value representing electric current flowing between an arm included in the inverter and the motor generator is greater than a threshold value, wherein when a reverse voltage by the motor generator is higher than a system voltage, the threshold value is larger than a value obtained by performing the predetermined process for electric current generated by the reverse voltage.
    Type: Grant
