Publication number: 20180345961Abstract: A vehicle control system for use with a host vehicle configured for travel along a path is described. The vehicle control system includes a processor configured to access a host location and host speed of the host vehicle. The processor is also configured to detect a follower location and follower speed of a following vehicle behind the host vehicle on the path. A tailgating distance is calculated between the host vehicle and the following vehicle. The following vehicle is identified as a tailgating vehicle when the tailgating distance is less than or equal to a first warning distance or when the follower speed is greater than the host vehicle within a second warning distance. A tailgating protocol of the host vehicle is initiated for the tailgating vehicle based on a differential speed between the host speed and the follower speed.Type: ApplicationFiled: August 8, 2018Publication date: December 6, 2018Inventors: Shigenobu Saigusa, Yoichi Sugimoto, Zeljko Medenica
