Claim Text:
1. A method for controlling a creep torque of a vehicle including a driving motor, comprising: determining, by a controller, whether the vehicle is in a creep driving state based on an accelerator pedal position value; determining, by a controller, whether a vehicle speed is greater than a set vehicle speed; determining, by a controller, at a first time whether a deceleration condition is satisfied when the vehicle speed is greater than the set vehicle speed; when the deceleration condition is satisfied at the first time, storing, by a controller, the first time at which the deceleration condition is satisfied and determining whether a deceleration release condition is satisfied; when the deceleration release condition is satisfied, determining, by a controller, at a second time whether the deceleration condition is satisfied; when the deceleration condition is satisfied at the second time, storing, by a controller, the second time at which the deceleration condition is satisfied; comparing, by a controller, an amount of time elapsed from the first time to the second time with a reference time; when the amount of time elapsed is less than the reference time, calculating, by a controller, a derating factor; and correcting, by a controller, a creep torque map by applying the derating factor.
