Claim:
1. An apparatus for controlling a creep torque, comprising: a driving system configured to deliver power to one or more wheels equipped in a vehicle; and a control unit configured to i) determine a driving mode of the vehicle, ii) calculate a creep torque based on a regenerative braking ratio of the vehicle while driving for a threshold time, and iii) control the driving system based on the calculated creep torque to convert the driving mode, wherein the control unit is further configured to change a first torque map correction factor to 1−(the regenerative braking ratio−a minimum regenerative braking ratio)/(a maximum regenerative braking ratio−the minimum regenerative braking ratio) and is further configured to change a second torque map correction factor to (the regenerative braking ratio−the minimum regenerative braking ratio)/(the maximum regenerative braking ratio−the minimum regenerative braking ratio), when the regenerative braking ratio is smaller than the maximum regenerative braking ratio and larger than the minimum regenerative braking ratio.
