The present invention provides a method for controlling a regenerative braking cooperation of an electric vehicle. The method for controlling a regenerative braking cooperation of an electric vehicle comprises: a correction mode entry step of entering a correction mode when a braking amount of a driver is detected from a pedal stroke sensor of a vehicle; a first braking pattern analyzing step of comparing a cumulative correction hydraulic braking amount and a predetermined first hydraulic braking amount for analyzing a braking pattern of the driver through entering the correction mode; a regenerative braking limit requesting step of transmitting a regenerative braking limit request signal of a motor to a control device when the driver determines a complete brake having the braking pattern when the cumulative correction hydraulic braking amount is smaller than the first hydraulic braking amount; and a hydraulic braking step of calculating the correction hydraulic braking amount based on the braking amount of the driver input in the stroke sensor while the regenerative braking of the motor is limited, and operating a hydraulic braking according to the correction hydraulic braking amount.

    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.
