1. A control device of a vehicle, the control device comprising:
a detector configured to detect an acceleration generated in a front-and-rear direction of the vehicle; and
an estimation unit configured to estimate an amount of nose dive of the vehicle during braking of the vehicle by:
calculating a braking force of an entirety of the vehicle and a pitch angle of the vehicle based on the acceleration detected by the detector,
calculating a braking force of a front brake of the vehicle based on the calculated braking force of the entirety of the vehicle and the calculated pitch angle of the vehicle, and
calculating an estimated amount of nose dive of the vehicle based on the calculated braking force of the front brake and a caster angle of the vehicle,
wherein a suspension mechanism of the vehicle is controlled based on the estimated amount of nose dive calculated to control an attitude of the vehicle during the braking of the vehicle.
