Hybrid vehicle and control method therefor

摘要

A hybrid vehicle and a control method of the hybrid vehicle is provided, capable of suppressing discharge of the battery at the time of starting a DC/DC converter and suppressing temporal voltage drop of the battery. When the engine is in the idle state and the power generated by the motor is not sufficient, the motor controller starts the DC/DC converter at a low output voltage state, and the amount of power generated by the motor is gradually increased at a speed without disturbing the idle rotation of the engine, and when it is determined that the power generation by the motor is sufficiently high by comparing the amount of power generation with the amount of power consumption at the output of the DC/DC converter, the operation mode of the output variable DC/DC converter is switched from the low voltage mode to the high voltage mode.
