Method for controlling braking of vehicle

A method for controlling braking of a vehicle calculates a driver request braking deceleration and a current frictional coefficient of a road surface to obtain a vehicle deceleration corresponding to the coefficient of the road surface.

A driving motor and a frictional braking device are controlled to generate the determined regenerative braking force and frictional braking force.
