摘要： A hybrid vehicle is provided that can be made to travel by means of motor generators (MG1, MG2) while an engine (E) is stopped, the engine (E), which can reduce pumping loss by running with a cylinder in a cut-off state, being connected to a front wheel (Wf) via the first motor/generator (MG1), an oil pump (13), a first clutch (14), a belt type continuously variable transmission (M), and a second clutch (20), and the second motor/generator (MG2) being connected to a rear wheel (Wr). When the vehicle is made to travel by driving or braking the rear wheel (Wr) with the second motor/generator (MG2), by driving the oil pump (13) with the first motor/generator (MG1) in a state in which the engine (E), which has stopped running, is put into a cylinder cut-off state and the second clutch (20) is disengaged, a hydraulic pressure for shifting the belt type continuously variable transmission (M) is generated. It is thereby possible to generate a hydraulic pressure for shifting the belt type continuously variable transmission (M) while the engine (E) is stopped, without requiring a special electric oil pump.

摘要： When a short-circuit failure of any of switch portions (13) including switch elements (11) and parallel-connected feedback diodes (12) of an inverter circuit (7) is detected during the operation of a motor (1), a switch portion (13) where the short-circuit failure has occurred is checked for whether it is on the positive polarity side or the negative polarity side. The switch elements (11) are so controlled that all the switch portions (13) on the same polarity side as where the short-circuit has occurred are brought into a conducted state and all the others disconnected. This prevents a large electric current from flowing into each switch portion of the inverter circuit without requiring any switch to block the power distribution between a motor and the inverter circuit when a short-circuit failure of the switch portion of the inverter circuit occurs.
