Problems solved by technology

[0006] However, the conventional electric power brake system as described above needs to continuously detect the pressure in the cylinder while driving the motor, and the ECU needs to constantly compare the detected pressure in the cylinder with the brake pressure, thus causing a calculation load Increased pressure control performance will be reduced, compared with the existing mechanical vacuum brake system, there is a problem that the braking feeling is reduced

Abstract

The present disclosure relates to an apparatus and a method for controlling a braking pressure of a powered booster brake system, the apparatus including a pedal stroke sensor configured to detect a manipulation degree of a brake pedal; an electronic control unit (ECU) configured to calculate a braking pressure using the detection result of the pedal stroke sensor; and a motor configured to move a piston inside a pump to perform a braking operation under control of the ECU, wherein the ECU determines a first position of the piston, which corresponds to the braking pressure, and controls the motor on the basis of a position of the piston.

Description

technical field [0001] The present invention relates to a brake pressure control device and method for an electric power-assisted braking system, in particular to a braking pressure control device for an electric power-assisted braking system capable of achieving the same braking feeling as a mechanical brake system and methods. Background technique [0002] In general, an electric power-assisted braking system is a braking system that effectively utilizes regenerative braking to improve the electric efficiency or fuel efficiency of an electric vehicle (EV) or a hybrid electric vehicle (HEV), and at the same time can feel a good braking feeling . [0003] The electric power-assisted braking system includes: a pedal travel sensor, which detects the operation of the brake pedal (Brake pedal); an electronic control unit (ECU), which converts the pressure detected by the pedal travel sensor into brake pressure, and The dynamic pressure controls the driving part of the driving ...
