VEHICLE POWER OUTPUT DEVICE AND ITS CONTROL METHOD

摘要

A vehicle power output device includes: a detection unit for detecting a failure of an electric connection path from a first connection terminal of a current control circuit (102) via a battery (B1) to a second terminal of the current control circuit (102); and a control device (30) for controlling the current control circuit (102) and a motor generator (MG1). When an engine (4) is shifted from an operation state to a stop state and if the detection unit does not detect a failure, the control device (30) causes the motor generator (MG1) to perform generation operation to generate a negative torque to promote stop of the engine (4) and causes the battery (B1) to collect the generated power. If the detection units detects a failure, the control device (30) inhibits the generation operation of the motor generator (MG1).
