1. A control device for a vehicle that includes (a) an engine provided in the vehicle via an engine mount and connected to first wheels that are either front wheels or rear wheels of the vehicle so as to be able to transmit power to the first wheels, and (b) a drive force source provided separately from the engine and connected to second wheels that are the other of the front wheels and the rear wheels of the vehicle so as to be able to transmit power to the second wheels, the control device comprising a processor configured to:
switch between two-wheel drive traveling in which the first wheels are driven by the engine, and four-wheel drive traveling in which the first wheels are driven by the engine and the second wheels are driven by the drive force source, and
increase a required drive amount of the drive force source when a required drive amount of the engine becomes equal to or greater than a predetermined value while the vehicle is traveling, wherein
the predetermined value is determined so that a load of the engine mount does not exceed a predetermined load of the engine mount, and
the predetermined load of the engine mount is a load at which a deformation amount of the engine mount does not exceed a predetermined threshold deformation amount of the engine mount.
