Abstract: The present invention relates to, for example, a vehicle control device including a driving force control unit that controls a driving force generated by a wheel of a vehicle; and a braking force control unit that controls a braking force generated by the wheel; where the driving force control unit generates the driving force of a first prescribed amount and the braking force control unit generates the braking force of a second prescribed amount to control the speed of the vehicle to be constant; and acceleration or deceleration are both controllable by performing one of control of the driving force by the driving force control unit and control of the braking force by the braking force control unit.

Abstract: A brake control device as an example of the present disclosure includes: 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 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.

Abstract: The present disclosure provides a brake control device applied to a vehicle including a hydraulic brake device that generates a hydraulic braking force by pressing a braking member with hydraulic pressure toward a member-to-be-braked that rotates integrally with a wheel; and an electric brake device that generates an electric braking force by pressing the braking member by driving a motor toward the member-to-be-braked. A controller that controls the electric brake device is provided. The controller executes, when a predetermined condition is satisfied, a positional control for driving a motor and moving a propeller shaft that transmits the driving force of the motor to the braking member toward the member-to-be-braked as compared to when the predetermined condition is not satisfied.
