HYBRID VEHICLE

摘要

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.

主权项

1. A hybrid vehicle comprising:
an engine; a first rotating electric machine including a permanent magnet in a rotor; an output shaft connected to drive wheels; a planetary gear mechanism that mechanically connects the engine, the first rotating electric machine, and the output shaft, such that reaction force of output torque of the first rotating electric machine acts on the output shaft, when the engine is in a driven state; a second rotating electric machine connected to the output shaft; a battery; an inverter configured to convert electric power between the battery, and the first rotating electric machine and the second rotating electric machine; and an electronic control unit programmed to a) perform inverterless traveling control, the inverterless traveling control being control for causing the hybrid vehicle to travel by placing the inverter in a gate cut-off state, and driving the engine, and b) 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.
