Abstract: Disclosed are a brake pedal assembly, a braking apparatus, and a control method, where the brake pedal assembly includes a pedal, a stroke sensor configured to detect a depression stroke of the pedal, Hall sensors spaced apart from each other in a direction parallel to an operation direction of the pedal, and a controller configured to determine the depression stroke of the pedal using any one or any combination of the stroke sensor and the Hall sensors and to determine a required braking force of a vehicle, in response to the depression stroke of the pedal.

Abstract: A method for controlling an ESC integrated braking system including: checking, by a control unit, whether a brake is in an on state or a standby state as the braking system is activated; checking, by the control unit, whether a current temperature value is in a low temperature state lower than specified reference temperature; and controlling, by the control unit, a current duty for driving a hydraulic control valve and a current component of a motor for driving a master cylinder according to the state of the brake and whether the current temperature value is in the low temperature state.

Abstract: Provided are an apparatus and method for performing rear-wheel regenerative braking control of an ESC integrated regenerative braking system. The apparatus includes: a pedal cylinder unit connected with a reserve unit in which oil is stored and configured to generate an oil pressure as a brake pedal is pressed; a motor driven by an electric signal that is output in response to displacement of the brake pedal; a master cylinder unit connected with the pedal cylinder unit; a control unit configured to perform reverse pressure control on the motor as much as a variation in a rear-wheel regenerative braking force if transition of the rear-wheel regenerative braking force occurs, and perform drive pressure control on the motor if the transition of the rear-wheel regenerative braking force is completed; and oil pressure relief valves provided on oil pressure lines that connect from the reserve unit to wheel cylinders.
