Publication number: 20250155890Abstract: 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.Type: ApplicationFiled: November 9, 2023Publication date: May 15, 2025Inventors: Kun-Sheng WANG, Tsung-Ming HSU
