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.

Abstract: A hybrid vehicle may include an engine, a first rotating electric machine, an output shaft, a planetary gear mechanism, a second rotating electric machine, a battery, an inverter and an electronic control unit. The electronic control unit may be programmed to perform inverterless traveling control. The inverterless traveling control may be control for causing the hybrid vehicle to travel by placing the inverter in a gate cut-off state, and driving the engine. The electronic control unit also may be programmed to interrupt current flowing between the first rotating electric machine and the battery when a shift range other than a forward range is selected, during the inverterless traveling control.

Abstract: Inverterless running control is control in which an inverter is set to a gate cut-off state, an engine is driven to mechanically rotate a motor-generator and to generate in the motor-generator, counter-electromotive torque in accordance with a difference between a counter-electromotive voltage of the motor-generator and a system voltage, and a vehicle runs with drive torque applied to an output shaft as reaction force of the counter-electromotive torque. An ECU controls drive torque to produce driving force determined by an accelerator position by raising or lowering the system voltage during inverterless running control.

Abstract: A vehicle includes an engine, an MG (motor generator) an MG2, a planetary gear device mechanically coupled to the engine and MG1 and MG2, a battery, an inverter configured to perform a power conversion between the battery and MG1 and between the battery and MG2, and a controller. MG1 generates a counter-electromotive torque when rotated by the engine. 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 engine target rotation speed Netag when an integrated value of battery charging current (deterioration evaluation value D) is greater than a predetermined value (threshold value D1) smaller than the engine target rotation speed Netag when the deterioration evaluation value D is equal to or smaller than the threshold value D1.
