Abstract
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.
