Development Of Vehicle Remote Controller Based On OSEK/VDX Norm

First, the thesis studies the samiler product on the market and points out what to be improved. Then, the thesis discusses the design of the high reliability vehicle mobile terminal of the vehicle monitoring system based on OSEK/VDX norm.OSEK/VDX norm composes of four parts: operating system specification, communication specification, network management specification and OSEK/VDX implement language. The OSEK/VDX operating system provides a series of different services and processing mechanism to control task and target hardware; the OSEK/VDX communication specification is a uniform communication environment for automotive control unit application software; the essential task of network management is to ensure the safety and reliability of a communication networks for electronics control units; the goal of OIL is to provide a mechanism to configure an OSEK/VDX application inside a particular CPU.With analysing the operation principle of a embedded real-time operating system uC/OS-II, the thesis studies the scheduling algorithm of uC/OS-II, the task switch mechanism and resource management function emphatically,etc. According to the definition of OSEK OS, project team improves and expands some functions of uC/OS-II kernel such as task switch algorithm, counter and alarm function module, and develops VSOS operating system kernal.The design of hardware and applicatin software of vehicle mobile terminal product is completed based on the VSOS operating system kernal. As hardware aspect, the thesis detailedly discusses the design of the key circuit ; as software aspect, based on the multi-task architecture, the thesis introduces message-driving mechanism and detailedly discusses the process of messaging between tasks and the manner of message being processed by each task.Finally, from hardware and software two aspects, the thesis sums up the experience of system reliability design. This experience is based on the problem encountered in the processing of development and has good practicability and reference. Further more, the thesis discusses the shortage of system and works out the next step work plan.
