ABSTRACT:
An ECU performs a program including a step of notifying a system main relay shut-off signal to a high-voltage system using equipment when a system main relay shut-off demand due to a HV system failure is generated, a step of shutting off the system main relay when a high voltage shut-off acknowledging signal from the high-voltage system using equipment is not unreceived, a step of shutting off the system main relay when a high voltage shut-off acknowledging signal from the high-voltage system using equipment is unreceived and a current value in a high voltage circuit is more than the predetermined threshold, and a step of shutting off the system main relay when the current value in the high voltage circuit is not more than the predetermined threshold and the predetermined period of time has elapsed from the occurrence of a HV system malfunction.
