1. A control device of a vehicle on which an internal combustion engine, a generator configured to generate electric power by power of the internal combustion engine, an electric motor capable of outputting a driving force to drive wheels, and a battery capable of supplying electric power to the electric motor are mounted, the control device is configured to perform control in either one of:
a first operation mode in which a driving force of the electric motor requested by a driver of the vehicle is set as a driver request driving force, a driving force of the electric motor derived based on the driver request driving force and a maximum limit value is set as a vehicle request driving force, and a first travel control in which the electric motor is operated by the electric power supplied from the battery and the vehicle request driving force is output from the electric motor is executed; and
a second operation mode in which a second travel control in which the electric motor is operated by the electric power supplied from the battery and the electric power generated by the generator to output the vehicle request driving force from the electric motor and a third travel control in which the electric motor is operated by the electric power supplied from the battery to output the vehicle request driving force from the electric motor are selectively executed, wherein:
in the first operation mode, the maximum limit value is set to a first maximum limit value that is a maximum electric power capable of being supplied from the battery to the electric motor;
in response to any one of a plurality of conditions for determining an end of the first operation mode being satisfied in a state in which the vehicle operates in the first operation mode, the first operation mode is switched to the second operation mode, and the maximum limit value is gradually increased, from the first maximum limit value to a second maximum limit value, at a rate of change determined in accordance with the satisfied condition, the second maximum limit value being a value larger than the maximum electric power; and
the second maximum limit value is a predetermined value larger than the maximum electric power.
