Graph Modelling of Pneumatic Vehicle Control System

Abstract

Pneumatic drive is an alternative to alternative car protrusion. However pneumatic engine control requires an adequate control system to fulfill all the requirements of being powerful, and economic in the same time. Like in conventional cars, the engine control requires microcontroller control, which is handling sensors data, and controlling actuators, like pressure-, and directional control valves in many driving modes. Thanks to Aventics/Emerson pneumobile competition many ways of vehicle control systems have been developed since 2008, including mechanical, electro-pneumatic, PLC, relays, and so on. Adequate control systems are already available, for all these methods, but flexibility, and reliability issues are forcing us to use different approach of design in order to recognize component impacts, and exposion to other components. Using this method help us to identify the components, which require special attention to make robust, or developing fault tolerant control method to keep up vehicle functionality in case of component failure.
