“…1 To reduce the impacts these emissions have, vehicle energy efficiency can be increased by traveling in platoons. [2][3][4] These formations minimize energy usage by reducing the effect of aerodynamic drag on each vehicle. The drag on vehicles in a platoon can be reduced by safely centering the follower as closely to the leader as possible.…”

“…As a result, the amount of energy that a vehicle must to consume to overcome aerodynamic resistance is lowered. [2][3][4] However, the task of identifying and minimizing the inter-vehicle offsets is nontrivial. A driver or an autonomous system must use environmental information to identify the offsets and how to best respond to them.…”

“…Lammert et al show that manual lateral control in a platoon can increase energy savings relative to driving freely. 2 Over the course of a platoon's trip but misalignments between a lead and follower vehicle could see a notable loss in energy savings. 2 These major offsets could occur during the course of a driver's operation time as their attention span diminishes.…”

“…2 Over the course of a platoon's trip but misalignments between a lead and follower vehicle could see a notable loss in energy savings. 2 These major offsets could occur during the course of a driver's operation time as their attention span diminishes. This is a dull and potentially dangerous task that a lateral control system could free a driver from having to perform.…”

Vehicle platooning allows a follower vehicle to reduce energy consumption by following closely behind a cooperative lead vehicle. In a previous work, we described a lidar-based vehicle detection and tracking approach that measures the extents of the back surface of the lead vehicle and allows for automated lane level positioning. In this work, we introduce a follower vehicle energy model and compare the performance of a vehicle centering strategy based on rear backplane geometry as opposed to center of mass and bounding box approaches. Energy efficiency improvements are discussed with respect to the computational complexity of each approach.

“…However, autonomous platooning is known in the research community as a group of autonomous vehicles moving by following a leader vehicle [7]. There are research studies that focus on efficient autonomous platooning with better fuel efficiency and better usage of road areas [8], [9]. Several researchers have proposed artificial intelligence (AI)-based solutions for the efficient organisation of vehicles [10].…”

Autonomous Convoying: A Survey on Current Research and Development

Convoying or platooning with a fleet of autonomous vehicles, which is denoted as autonomous convoying in this paper, has attracted increasing attention from the research communities, governments, and private sectors in recent years. Autonomous convoying offers immense opportunities due to its potential in enhancing logistical efficiency as well as reducing road incidents/accidents by eliminating human errors due to stress and fatigue. While humans can make complex decisions, involving humans in decision-making processes often causes delays as compared with those of automated machines. Indeed, human errors cause approximately 90% of road accidents and fatalities. Efficient platooning techniques can also reduce fuel consumption and carbon footprints. This paper presents a concise survey on current research and development initiatives in autonomous convoying while critically discussing the underlying techniques and technologies developed in this domain. Implications of autonomous convoying toward different industries are also analyzed and discussed.
