车载防盗与信息娱乐系统集成设计

摘要

为了解决汽车被盗的问题，同时满足车载电子系统功能更加多元化的趋势，提出一种将汽车防盗和信息娱乐功能集成设计的方法，并结合CAN总线通信技术，设计和实现了一套集汽车防盗、信息娱乐功能于一体的智能化系统。重点介绍系统的开发意义，中央控制单元和CAN网络节点的软硬件设计以及实现过程，对系统进行可靠性和功能性分析和测试。实验结果表明，该系统具有运行稳定、实时性强、可靠性高等优点，符合车载电子系统“更安全、更环保、更节能”的发展趋势，具有广泛的应用价值。%To solve the problem of vehicle theft,meet the development trend of diversified in vehicle electronic system function,the method is proposed to design the vehicle theft and infotainment function integrated. Based on CAN bus communica⁃tion technology,a new intelligent system that consists of vehicle theft and vehicle infotainment is designed and implemented. The significance of the proposed system development is emphasis introduced,the software/hardware design and implementation process of the central control unit and CAN network node are detailed. The reliability and functionality of the system is tested and analyzed,the results show that the system has good stability,better real⁃time ability,high reliability,extensive value in ap⁃plications,and satisfies the development trend of“safer,greener and more energy efficient”in vehicle electronic system.
