Abstract
A vehicle includes an engine, an MG (motor generator), an MG, a planetary gear device mechanically coupled to the engine and MGand MG, a battery, a converter configured to boost a voltage from the battery, an inverter configured to perform a power conversion between the converter and MGor between the converter and MG, and a controller. MGgenerates a counter-electromotive voltage when rotated by the engine, and a braking torque is generated as the counter-electromotive voltage becomes greater than the output voltage of the converter. During an inverter-less running control where the inverter is put into a gate shut-off state and the engine is driven to cause MGto generate the counter-electromotive torque, the controller decreases a voltage difference between the counter-electromotive voltage and the output voltage of the converter when a chargeable power of the battery is lower than a predetermined value.
