The present invention relates to a creep torque control method of an electric vehicle capable of preventing the push in the climbing start by controlling creep torque with a climbing angle sensor (G sensor) and a brake pedal value only in the stop state during the operation of a vehicle. The creep torque control method of an electric vehicle comprises; (a) a step of confirming whether the vehicle is stopped or not with a vehicle speed; (b) a step of determining an inclination angle based on a value of the climbing angle sensor in the stop state of the vehicle and determining maximum creep torque corresponding to the inclination angle; (c) a step of determining a push starting point and a control starting point in the inclination angle; and (d) a step of determining a creep torque value according to a value in which the brake pedal is relaxed based on the determined control starting point and controlling torque with the determined creep torque. Therefore, the push of an electric vehicle can be presented by controlling the creep torque with the climbing angle sensor (G sensor) and the brake pedal value in the stop state during the operation of the vehicle. Moreover, a torque impact can be avoided by increasing the torque slowly in the stop state during the operation of the vehicle and the push of the vehicle can be prevented in the climbing start. |
