Lamp system for traffic lane indication using navigation link and method for traffic lane indication thereof

A method for traffic lane indication by a lamp system of a host vehicle for traffic lane indication using a navigation link, the method comprising:

• receiving, by a vehicle controller of the host vehicle, forward line information through a multi-function sensor sensing an environment and a line on a road surface in front of the host vehicle;
• receiving, by the vehicle controller, location information of the host vehicle through a navigation device;
• predicting, by the vehicle controller, a forward line based on a line sensed by the multi-function sensor and the location information of the host vehicle provided by the navigation device;
• controlling, by the vehicle controller, a line lamp to output a prediction line to follow the predicted forward line,
• analyzing, by the vehicle controller, the location information of the host vehicle after capturing the prediction line through the multi-function sensor;
• and
• displaying, by the vehicle controller, the prediction line and a location of the host vehicle on a display of the host vehicle,
• wherein the controlling of the line lamp includes:
• controlling only the line lamp not to output the prediction line when there is another vehicle that is moving in an opposite direction than a direction in which the host vehicle is moving, or when there is another vehicle that is in front of the host vehicle and is moving in a same direction in which the host vehicle is moving.

A lamp system for providing an optimal vehicle path indication, the lamp system comprising:

• a multi-function sensor to sense an environment and a path on road surface directly in front of a host vehicle on which the host path is set to travel on;
• a line lamp to generate and output a prediction line at a location corresponding to the path on the road surface;
• a location information device to provide location information of the host vehicle;
• and
• a vehicle controller configured to:
• predict a forward line based on the line sensed by the multi-function sensor and the location information of the host vehicle provided by the location information device;
• control the line lamp to output the prediction line to follow the predicted forward line,
• analyze the location information of the host vehicle after capturing the prediction line through the multi-function sensor;
• and
• display the prediction line and a location of the host vehicle on a display of the host vehicle,
• wherein the vehicle controller controls the line lamp not to output the prediction line when there is another vehicle that is moving in an opposite direction than a direction in which the host vehicle is moving, or when there is another vehicle in front of the host vehicle that is Moving in a same direction in which the host vehicle is moving.
