US Patent 10406935 Travel driving apparatus of vehicle

In a hybrid vehicle including a front motor for driving front wheels, a rear motor for driving rear wheels, a generator for generating power by being driven by an internal combustion engine, and a step-up converter for stepping up the voltage from a battery and supplying power to the front motor, while stepping-down the generated power of the generator and supplying the power to the rear motor, a hybrid control unit decreases the power supplied from the generator to the rear motor, and increases the power supplied from the battery to the rear motor when input power of the step-up converter is limited based on a temperature condition of the step-up converter.
