  • Series-connected brake actuators and automatic brake hold method employing same
    Patent number: 12017623
    Abstract: A brake system includes a master cylinder configured to generate a hydraulic pressure, a primary brake actuator configured to increase and decrease the hydraulic pressure generated in the master cylinder, a secondary brake actuator connected in series with and downstream of the master cylinder and in series with and upstream of the primary brake actuator, and configured to increase and decrease the hydraulic pressure generated in the master cylinder, and at least one wheel cylinder configured to apply brake torque to a wheel of a vehicle based on the hydraulic pressure generated by the master cylinder and increased or decreased by the primary actuator or the secondary actuator. An automatic brake hold control method includes sequential performing an automatic brake hold control on at least one wheel cylinder by the primary brake actuator and then the secondary brake actuator.
