2. 1. Fuel-Efficient Distributed Control for Heavy Duty Vehicle Platooning

   Author : Assad Alam; Karl Johansson; Ather Gattami; Roy Smith; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Heavy Duty Vehicle; Platooning; Fuel; Reachability; Game Theory;

   Abstract : Freight transport demand has escalated and will continue to do so as economiesgrow. As the traffic intensity increases, the drivers are faced with increasinglycomplex tasks and traffic safety is a growing issue. Simultaneously, fossil fuel usageis escalating. Heavy duty vehicle (HDV) platooning is a plausible solution to theseissues. READ MORE
