1. A control device mounted on a vehicle, the control device comprising:
one or more processors configured to:
acquire a first braking force based on an operation amount of an acceleration pedal when a driver operation is performed on the acceleration pedal;
calculate a maximum value of the first braking force,
wherein the maximum value of the first braking force is a maximum value that can be generated according to the operation amount of the accelerator pedal when an operation amount of a brake pedal is zero;
calculate a second braking force corresponding to the operation amount of the accelerator pedal;
when the second braking force is larger than the maximum value of the first braking force, instruct a controller of the brake to generate a third braking force corresponding to a difference between the second braking force and the maximum value of the first braking force;
acquire a fourth braking force that is generable by a powertrain; and
when a portion of the second braking force within a range up to the maximum value is larger than the fourth braking force that is generable by the powertrain, instruct a controller of the powertrain to generate the fourth braking force that is generable by the powertrain, and instruct the controller of the brake to generate the third braking force corresponding to a difference between the portion of the second braking force that falls within the range up to maximum value and the fourth braking force that is generable by the powertrain.
