Abstract
An OR circuit 61 of a relay drive unit 60 provides an ON output when at least one of a drive signal output from a battery ECU 52 and a latch signal output from an HVECU 70 is ON signal, while providing an OFF output when both the drive signal and the latch signal are OFF signals. The HVECU 70 switches off the latch signal when the engine operates, while switching on the latch signal when the engine is at stop. When no abnormality of communication with the HVECU 70 is detected and a specified time duration has not elapsed since detection of the abnormality of communication with the HVECU 70, the battery ECU 52 switches on the drive signal. When the specified time duration has elapsed since detection of the abnormality of communication with the HVECU 70, the battery ECU 52 switches off the drive signal.
