본 발명은 차량의 페달 스트로크 센서로부터 운전자의 제동량이 감지되면 보정모드로 진입하는 보정모드 진입단계와 상기 보정모드로의 진입을 통해 운전자의 제동패턴을 분석하기 위하여 누적 보정유압제동량과 기설정된 제1유압제동량을 비교하는 제1제동패턴 분석 단계와 상기 누적 보정유압제동량이 상기 제1유압제동량 보다 작은 경우, 운전자가 완제동을 위주의 제동패턴을 가진 것으로 판단하여 제어기로 모터의 회생제동 제한 요청 신호를 전달하는 회생제동 제한 요청 단계 및 상기 모터의 회생제동이 제한된 상태에서 상기 스트로크 센서에 입력된 운전자의 제동량을 기준으로 보정 유압제동량을 계산하고, 상기 보정 유압제동량에 따라 유압제동이 작동하도록 하는 유압제동 단계를 포함한다.

    A method of controlling a regenerative braking cooperation for an electric vehicle may include a entering a correction mode when a braking quantity of a driver is detected by a pedal stroke sensor, a first braking pattern analyzing operation, of comparing an accumulated correction hydraulic pressure braking quantity with a predetermined first hydraulic pressure braking quantity, a regenerative braking restriction requesting operation of, when the accumulated correction hydraulic pressure braking quantity is smaller than the first hydraulic pressure braking quantity, determining, that the driver has a gradual braking-centered braking pattern and transferring a signal for requesting a regenerative braking restriction of a motor to a controller, and a hydraulic pressure braking operation, of determining a correction hydraulic pressure braking quantity based on a braking quantity of the driver input into the stroke sensor in a state where regenerative braking of the motor is restricted, and performing a hydraulic pressure braking.
