A MG-ECU is provided in a hybrid vehicle having an MG and an engine and starts the engine by controlling the MG. When the MG-ECU detects a disconnection in any one of three-phase power supply wires, which supply the MG with power, the MG-ECU permits driving of the MG on condition that the engine is requested to be started. The MG-ECU limits a command torque for the MG is limited to be equal to or less than a predetermined torque value than in a case of presence of no disconnection, when the MG is permitted to be driven.
