Abstract: A vehicle includes an engine, an MG (motor generator) 1, an MG2, a planetary gear device mechanically coupled to the engine and MG1 and MG2, a battery, a converter configured to boost a voltage from the battery, an inverter configured to perform a power conversion between the converter and MG1 or between the converter and MG2, and a controller. MG1 generates 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 MG1 to 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.

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.

Abstract: When a malfunction occurs in communication between an HV-ECU and an MG-ECU, inverterless running is performed to ensure that a driving torque of a vehicle is applied, by setting inverters in a gate shutoff state and using a braking torque generated in a motor generator rotated by an engine. When the inverterless running resulting from the malfunction in communication is performed, the MG-ECU uses a converter to control a system voltage VH to a predetermined voltage. During the inverterless running resulting from the malfunction in communication, the HV-ECU sets an assumed power range of a battery based on a detected value regarding a vehicle running state and the predetermined voltage. When an actual electric power determined from the voltage and current of the battery is out of the assumed power range, the HV-ECU performs a process for stopping the vehicle from running.
