1. A brake control device, comprising:
an acquisition unit configured to acquire an output of a sensor that detects information indicating a ground contact state of a drive wheel of a plurality of drive wheels of a vehicle; and
a control unit configured to, when an acceleration operation for causing the vehicle to accelerate is performed on the vehicle stopped due to a parking brake force generated by an electric parking brake, identify the ground contact state of the drive wheel based on the output of the sensor acquired by the acquisition unit, and control the electric parking brake to release the parking brake force by a control method that differs depending on the identified ground contact state, wherein
the control unit adjusts, according to the ground contact state of the drive wheel, a temporal change in the parking brake force when releasing the parking brake force, so that the temporal change in the parking brake force is more gradual than in a case where the ground contact state of the drive wheel is not taken into consideration.
