Brake system having drag reduction function and method of controlling the same

摘要

A brake system may have a drag reduction function of effectively attenuating drag by controlling the position of a pressurizing piston in a pressurizing cylinder through a motor to supply a fluid in a hydraulic line to the reserve tank such that negative pressure is created to forcibly withdraw the piston in a caliper, and a method of controlling the same. The brake system may include a pressurizing cylinder connected to a reserve tank to store a fluid, a motor to move a pressurizing piston forward, and a braking control unit to receive state information about the vehicle to determine whether the vehicle is braking or traveling, execute, when the vehicle is traveling, a negative pressure creation mode of driving the motor to move the pressurizing piston forward to create a negative pressure, and execute, when creation of the negative pressure is completed, a negative pressure maintaining mode.

主权项

1. A brake system to perform braking to decelerate or stop a vehicle, the brake system comprising:
a pressurizing cylinder connected to a reserve tank adapted to store a fluid; a motor to move a pressurizing piston forward in the pressurizing cylinder; and a braking control unit to receive state information about the vehicle to determine whether the vehicle is braking or traveling, execute, when the vehicle is traveling, a negative pressure creation mode of driving the motor to move the pressurizing piston forward to create a negative pressure, and execute, when creation of the negative pressure is completed, a negative pressure maintaining mode of maintaining the negative pressure.
