1. A system comprising:
- at least one first light source projector with at least one first positional actuator mounted on a subject vehicle that projects a first laser line on a roadway upon which the subject vehicle is traveling; and
a first controller in communication with a second controller of a platoon vehicle traveling in front of or behind the subject vehicle in a platoon, the platoon vehicle having at least one second light source projector with at least one second positional actuator mounted on the platoon vehicle that projects a second laser line on the roadway upon which the platoon vehicle is traveling;
wherein the first controller controls the at least one first positional actuator to project the first laser line on the roadway, parallel to a lane line of the roadway, between the subject vehicle and the platoon vehicle;
wherein the second controller controls the at least one second positional actuator to project the second laser line on the roadway, parallel to the lane line of the roadway, between the subject vehicle and the platoon vehicle; and
wherein the first controller and the second controller communicate with each other to coordinate operation of the at least one first positional actuator and the at least one second positional actuator to overlap the first laser line with the second laser line to form a continuous laser line between the subject vehicle and the platoon vehicle while the subject vehicle and the platoon vehicle are traveling on the roadway.

Abstract
A system and method are provided and include a light source projector with a positional actuator mounted on a subject vehicle that projects a laser line on a roadway upon which the subject vehicle is traveling. A controller is in communication with a platoon vehicle traveling in front of or behind the subject vehicle in a platoon and controls the positional actuator to project the laser line on the roadway between the subject vehicle and the at least one platoon vehicle.

10. A method comprising:
-
projecting, with at least one first light source projector having at least one first positional actuator mounted on a subject vehicle, a first laser line on a roadway upon which the subject vehicle is traveling; controlling, with a first controller, the at least one first positional actuator to project the first laser line on the roadway, parallel to a lane line of the roadway, between the subject vehicle and a platoon vehicle traveling in front of or behind the subject vehicle in a platoon; and communicating, using the first controller, with a second controller of the platoon vehicle, the platoon vehicle having at least one second light source projector with at least one second positional actuator mounted on the platoon vehicle, the second controller controlling the at least one second positional actuator to project a second laser line on the roadway, parallel to the lane line of the roadway, between the subject vehicle and the platoon vehicle; wherein the first controller and the second controller communicate with each other to coordinate operation of the at least one first positional actuator and the at least one second positional actuator to overlap the first laser line with the second laser line to form a continuous laser line between the subject vehicle and the platoon vehicle while the subject vehicle and the platoon vehicle are traveling on the roadway. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
