  • Patent number: 11938916
    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.

  • Publication number: 20220410721
    Abstract: The present disclosure is, for example, a braking control device for application in a vehicle. The braking control device includes: a hydraulic brake device that presses a braking member using hydraulic pressure toward a braked member that rotates integrally with a wheel to generate hydraulic braking force; and an electric brake device that presses the braking member using driving force of a motor toward the braked member to generate electric braking force. The braking control device adjusts the hydraulic braking force so that a vehicle speed falls within a target vehicle speed range while the vehicle is traveling on a downhill road, and replaces the hydraulic braking force with the electric braking force when at least one of the vehicle speed and the hydraulic pressure is stabilized.

  • Patent number: 11440524
    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.

  • Publication number: 20220017056
    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.
