1. A control device for a vehicle configured to travel in a one-pedal mode in which driving and braking are controlled in response to operations on only an accelerator pedal, the control device comprising an electronic control unit configured to:
control a braking force of the vehicle by using deceleration maps in which decelerations in a plurality of traveling directions are set for any points based on traveling history data, and
calculate, during traveling in the one-pedal mode, a deceleration level based on deceleration information associated with a current traveling direction and a current position of the vehicle among pieces of deceleration information included in the deceleration maps, wherein:
the deceleration level includes a plurality of deceleration levels in which a maximum deceleration generated when the accelerator pedal is released is set to different magnitudes stepwise, and
the electronic control unit is configured to
automatically change a setting to the calculated deceleration level during the traveling in the one-pedal mode, and
calculate a requested deceleration based on the set deceleration level when controlling the braking force of the vehicle.
