The present invention relates to a vehicle and a control method of the vehicle. The vehicle according to one embodiment of the present invention may comprise: a motor; a gearbox; a vehicle speed sensor which detects a vehicle speed; and a control unit. If the vehicle satisfies a creep driving condition, the control unit determines a first creep torque based on a driving mode of the vehicle and determines a correction coefficient based on a surrounding environment of the vehicle, applies at least one of the correction coefficient and an engine friction torque to the first creep torque, and determines a second creep torque and controls the motor to transmit the second creep torque to a wheel of the vehicle. According to the present invention, sense of heterogeneity due to a gear step may be reduced. 본 발명의 일 실시예에 따른 차량은 모터, 변속기, 차량의 속도를 감지하는 차속 센서 및 상기 차량이 크립 주행 조건을 만족하는 경우, 상기 차량의 주행 모드에 기초하여 제 1 크립 토크를 결정하고, 상기 차량의 주변 환경에 기초하여 보정 계수를 결정하고, 상기 보정 계수 및 엔진 마찰 토크 중 적어도 하나를 상기 제1 크립 토크에 적용하여, 상기 제 2 크립 토크를 결정하고, 상기 제 2 크립 토크를 상기 차량의 휠에 전달하도록 상기 모터를 제어하는 제어부를 포함할 수 있다.
