PURPOSE: A braking control method of a vehicle which improves reliability of breaking performance and control response is provided to control vehicle according to the desire vehicle deceleration rate of a user. CONSTITUTION: A braking control method of a vehicle which improves reliability of breaking performance and control response is as follows. The offset of a brake pedal is input in the car braking(S10). The demand deceleration speed of an operator is calculated based on the offset and deceleration map of a pedal(S20). The real deceleration value is input in the braking of a car(S30). A first revision coefficient is produced in order to revise the difference of the demand deceleration of an operator and the accrual deceleration(S40). The slope of the actual deceleration is produced in order to determine an urgent braking state. The second revision coefficient for revising the urgent braking state is calculated(S50). . The first revision coefficient and the second revision coefficient are applied to the current brake pressure in order to calculate the target medicine differential pressure(S60). The brake pressure of each wheel is controlled with the target medicine differential pressure(S70). |
