US Patent 10011281 Lane change device, system including the same, and method thereof

A lane change device, a system including the same, and a method thereof are provided. The lane change system includes a sensor unit that senses a rotational angular velocity of a turn signal lever of a subject vehicle, an electric field signal of a gear lever of the subject vehicle, and distances between the subject vehicle and neighboring vehicles. A processor then sets a driving mode using the rotational angular velocity, the electric field signal, and the distances between the subject vehicle and the neighboring vehicles, generates a lane change path based on the driving mode, and executes a lane change of the subject vehicle.
