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.

    본 발명은, 비대칭 노면 출발시, 양쪽 휠의 제동압 차이가 설정된 임계치보다 큰지 판단하는 단계, 상기 제동압 차이가 상기 임계치보다 크면, 요레이트 센서에서 측정된 요 각속도를 기반으로 차량자세제어를 요구하는지 결정하는 단계 및 상기 차량자세제어가 미요구로 결정되면, 조향각 센서에서 측정된 조향각이 설정된 직진 임계값에 속하면, ECS ECU가 보조 조향토크값을 산출하여 EPS ECU로 전달하는 단계를 포함하는 자동차의 구동제어방법을 제공한다.
