System and Method to Operate an Automated Vehicle

Systems and methods for operating an automated vehicle such as an autonomous vehicle may include an autonomous guidance system, a method of automatically controlling and autonomous vehicle based on electronic messages from roadside infrastructure or other-vehicles, a method of automatically controlling an autonomous vehicle based on cellular telephone location information, pulsed LED vehicle-to-vehicle (V2V) communication system, a method and apparatus for controlling an autonomous vehicle, an autonomous vehicle with unobtrusive sensors, and adaptive cruise control integrated with a lane keeping assist system. The systems and methods may use information from radar, lidar, a camera or vision/image devices, ultrasonic sensors, and digital map data to determine a route or roadway position and provide for steering, braking, and acceleration control of a host vehicle.
