1. A vehicle control device that controls a vehicle, the vehicle comprising an internal combustion engine, a power storage device, an electric motor that performs driving based on supply of electric power from at least the power storage device, and a drive wheel that is driven by at least one of the internal combustion engine and the electric motor, the vehicle control device comprising:
circuitry configured to:
execute motor assist when the vehicle is traveling by the drive wheel being driven by the internal combustion engine, in which electric power of the power storage device is supplied to the electric motor and the electric motor assists driving of the drive wheel;
change upper-limit assist electric power, which is an upper-limit value of electric power supplied from the power storage device to the electric motor in order to perform the motor assist, in accordance with a temperature of the power storage device; and
when the temperature of the power storage device reaches a first temperature, restrict the upper-limit assist electric power such that a reduction amount of a maximum driving force of the vehicle falls within an allowable range,
wherein the upper-limit assist electric power is changeable in accordance with a speed of the vehicle,
wherein when the speed of the vehicle reaches a first speed in a state where the temperature of the power storage device has reached a second temperature higher than the first temperature, the upper-limit assist electric power is reduced according to an increase in the speed of the vehicle, and
wherein when the speed of the vehicle reaches a second speed higher than the first speed in a state where the temperature of the power storage device has reached the second temperature, the upper-limit assist electric power is set to 0.
