Control device for electrified vehicle, electrified vehicle, and control method therefor

An electrified vehicle comprising:

• a battery;
• an electric motor that is driven by electric power from the battery to output power when the vehicle is traveling, and regenerates electric power when the vehicle is braked;
• an inverter that exchanges electric power between the battery and the electric motor;
• and
• a processor configured to
• drive the vehicle in one of a first driving mode and a second driving mode with different levels of automatic driving, wherein a level of the automatic driving is higher in the first driving mode than in the second driving mode so that involvement of a driver of the vehicle is higher in the second driving mode than in the first driving mode;
• set an upper limit of an amount per unit time of electricity that enters into and exits from the battery to a first upper limit amount when the processor drives the vehicle in the first driving mode, the first upper limit amount being less than a second upper limit amount that is set in the second driving mode;
• and
• control the inverter within a range in which the amount of electricity that enters into and exits from the battery does not exceed the first upper limit amount or the second upper limit amount set by the processor.

A control method for an electrified vehicle, comprising:

• outputting power for travel of the vehicle from an electric motor by outputting electric power from a battery to the electric motor via an inverter when the vehicle is traveling;
• regenerating, via the inverter, electric power generated by the electric motor, using at least a part of a braking force, when the vehicle is braked;
• driving the vehicle in one of a first driving mode and a second driving mode with different levels of automatic driving, wherein a level of the automatic driving is higher in the first driving mode than in the second driving mode so that involvement of a driver of the vehicle is higher in the second driving mode than in the first driving mode;
• setting an upper limit of an amount per unit time of electricity that enters into and exits from the battery to a first upper limit amount when the vehicle is driven in the first driving mode, the first upper limit amount being less than a second upper limit amount that is set in the second driving mode;
• and
• controlling the inverter such that the amount of electricity that enters into and exits from the battery is less than the first upper limit amount or the second upper limit amount.
