The present invention provides a drive control method of a vehicle. The drive control method of a vehicle comprises: a step of determining whether the brake pressure difference between both side wheels is larger than a set threshold when a vehicle starts on an asymmetric road; a step of determining whether a vehicle posture control is required or not on the basis of a yaw angular speed measured in a yaw rate sensor if the brake pressure difference is larger than the threshold; and a step of allowing an electric control unit (ECU) of an electronic stability controller (ESC) to calculate an auxiliary steering torque value and transfer the calculated auxiliary steering torque value to an ECU of an electronic power steering (EPS) if the steering angle measured in a steering angle sensor is within the a direct motion threshold when the vehicle posture control is not required. Therefore, the present invention prevents excessive steering.
