Design of a Digital Dash-Panel using a TFT LCD Panel and Blackfin Processor

The following document discusses the benefits achieved from implementing a digital dash-panel within an automobile. It details the synthesis of the digital display system using the appropriate hardware components and software strategies. The justifications behind the selection of the Blackfin processor for controlling the system are outlined. In addition, a brief discussion of the safety aspects obtained from the digital dash-display is discussed.

Fuzzy Logic Controller Implementation in ANSI C

This paper outlines the development of software in ANSI C to implement a fuzzy controller. A fuzzy controller can provide control to many different actuators in a vehicle where a mathematical model of a system is vague or highly complex, such as a climate control system. During the design stage, emphasis was placed on memory requirements and computational efficiency due to the fact that the final system was to be implemented on a microcontroller. This paper provides an outline of the choices made along with an overview of the methods and algorithms used to successfully implement the controller.

Using UML 2.0 to Create Executable Code from Requirements Capture and Consistent Requirement Specifications for Real-Time Automotive Software Development

The development of vehicle control systems has evolved to become an exercise in the design and integration of complex, distributed hardware and software components. The various components are typically developed by geographically dispersed, multicultural teams from both OEMs and suppliers. This paper gives a brief overview of using the Unified Modelling Language (UML) as a means of capturing the requirements of real-time distributed systems in a graphical notation shared by all team members. UML is commonly used to model system concepts, albeit typically as system “sketches” without any formal definition of the model's semantics. This paper specifically addresses the additions to the latest version of UML that supports higher levels of abstraction, model-based development, executable models and the specification of non-functional requirements.
