A new concept of brake system for ITS platoon heavy duty trucks and its pre-evaluation

Previously ITS system or ITS technology was aiming some of new brake through technologies. It is quite important for beginning of ITS. Currently ITS engineers need to consider more mass production aspect, such as less energy consumption, cost efficiency, system´s redundancy and so on. However those are kind of difficult to be succeed at the same time. Especially, brake system is not simple to achieve both redundancy and cost efficiency. Another aspect of consideration for platoon truck needs individual required deceleration G when the system is failed to maintain a short range distance. Naturally, the only way to avoid a collision is that the driver voluntary activate their brake. However, if all of the platoon trucks has the same maximum deceleration G, it would make a collision because of short range distance. Thus individual deceleration G within a short distance range for the platoon truck is key point of avoiding collision. In this paper, a new concept of brake system was proposed to solve such difficulties. In addition, in order to satisfy some of the brake system´s necessities, the author focused on using previous EBS system properties and adding an active brake air flow control. This system can control real time brake air, which is based on individual vehicle´s required deceleration G, payload and son on.
