Abstract
When at least one of motor generators is not under normal control and where the MGtemperature is less than an upper limit value, an ECU is configured to perform an inverter-less running control. In the inverter-less running control, an inverter is brought into a gate shutoff state and an engine is driven to cause the motor generator to generate a counter-electromotive voltage which consequently produces a counter-electromotive torque. During the inverter-less running control, the ECU makes a voltage difference between the counter-electromotive voltage and the voltage of a power line connecting a converter and an inverter when the MGtemperature is equal to or greater than a predetermined value smaller than the voltage difference when the MGtemperature is less than the predetermined value.
