An auto cruise system includes a compensating torque generator, an auto cruise controller, a first calculator, a PI controller, a second calculator, a torque saturator, and a torque command limiter. The compensating torque generator generates a compensating torque based on road conditions. The auto cruise controller detects a time at which a torque limitation is released, and adjusts target speed at that time. The first calculator calculates an error based on a difference between the current speed of the vehicle and the target speed adjusted by the auto cruise controller. The PI controller calculates torque corresponding to the error. The second calculator compensates the torque calculated by the PI controller. The torque saturator defines an upper value and a lower value of the torque compensated by the second calculator. The torque command limiter limits the torque which is physically saturated in the actuator by the available torque saturator.
