Vehicle platoon intersection decision-making system and method thereof

Abstract

A vehicle platoon intersection decision-making system includes multiple vehicles. When executing the intersection decision-making process, the captain vehicle determines whether the platoon can pass through the intersection at the current speed command; if yes, the captain vehicle directs each vehicle to maintain travelling at the current speed command to pass through the intersection; if not, the captain vehicle generates a first optimized speed control information through a first speed decision-making process, making the platoon decelerate before reaching the intersection and begin to accelerate at an acceleration critical time point such that the platoon passes through the intersection. When the platoon passes through the intersection at the current speed command, no energy for accelerating or decelerating is wasted. The platoon decelerates first and then begins to accelerate at the appropriate time through the intersection, avoiding or reducing the time spent waiting for traffic lights at the intersection.
