An apparatus for escaping an uneven driving surface for an electric vehicle includes a maximum traction identification portion configured to search for a steering angle at which maximum traction is generated by applying driving torque while rotating the steering wheel. The maximum traction identification portion is also configured to identify maximum wheel torque able to be applied after rotating the steering wheel by the steering angle at which maximum traction is generated. The apparatus also includes an axle weight computation portion configured to repeatedly calculate an axle weight applied to front and rear wheels of a vehicle in which various pitching motions are implemented. The apparatus also includes a driveaway controller configured to receive information from the maximum traction identification portion and the axle weight computation portion and to control escape of the vehicle.
