The invention provides a braking control method of a vehicle. The vehicle comprises a motor and a mechanical braking mechanism. The method comprises the following steps of outputting the motor braking torque by the motor to brake the vehicle; in the process of braking, obtaining a wheel slip rate according to a speed signal and a wheel rotation speed signal; judging whether the wheel slip rate is within a preset range; if the wheel slip rate is not within the preset range, further judging whether the wheel slip rate is less than the lower limit of the preset range; if the wheel slip rate is less than the lower limit of the preset range, judging whether to increase the motor braking torque or combine with the mechanical braking mechanism to brake the vehicle to shorten the braking distance of the vehicle according to the motor braking torque and expected braking torque. By applying the method, the braking distance can be shortened to the maximum, and locking and slipping of wheels are avoided, so that the braking safety of the vehicle is improved. The invention also provides a braking control system of the vehicle.
