A new platoon control concept is introduced, called Back Control, in which the controller of a given vehicle utilizes state information from lead, preceding, and following vehicles, as well as the vehicle itself. Simulations are carried out on two non-steady state platoon operations - vehicle exit and vehicle entry from a platoon. A previously developed longitudinal controller is utilized as a reference to the proposed Back controller and a ride quality index is used to assess passenger comfort in these simulations. It is shown that the Back controller has advantages over the reference controller in these two operations and that it is therefore worth examining as a candidate controller of vehicular platoons, especially in non-nominal operations. In the current simulations, the Back controller has shown the capability of providing a better ride quality and reduced the possibility of an intra-platoon collision. It is concluded that the Back control approach merits further investigation as it may provide an enhanced safety level for platoon operations. It should also be noted that this controller does not require additional sensors, the rearward vehicle states could be transmitted via the same network that carries the lead vehicle information. However, additional sensors would certainly have attractive aspects, as they would add some redundency to the sensor system. In the event of a forward facing sensor's failure, the rear sensors could take over.
