中文摘要： CAN总线已经成为当今最成功的车载网络标准，广泛应用于现代汽车控制系统中。但是随着科学技术的发展，对汽车操控性、舒适性要求的提高，车内电子控制单元数量迅速增加，汽车CAN总线车载网络在大数据量传输时的有效性、实时性以及带宽资源利用率已不能满足今后汽车网络化发展的需求。为了解决这些问题，本项目拟在车载网络数据智能调度算法和车内电子控制单元性能优化两个方面开展研究。首先，将处理器中多任务调度算法思想引入汽车CAN网络控制系统中，提出DISA智能调度算法，能够有效减小高优先级数据的传输延时，提高汽车车载网络对大数据量传输时的有效性和实时性。其次，研究汽车CAN总线网络中当传输的数据趋于饱和时，通过对网络上电子控制单元性能的优化与管理，达到减少网络带宽使用量，提高汽车车载网络的控制性能和传输性能的目的。研究结果可为今后汽车的网络化和智能化发展提供新的科学资料和理论依据。

英文摘要： The CAN bus has become the most successful vehicle network standard and widely used in automotive control systems. Following by the rapid development of technology, and the requirement of handling and comfort, as well as the increasing number of vehicle electronic control unit, the validity, real-time and bandwidth resource utilization of the vehicle CAN bus vehicle networks can not meet the development of automotive. To solve these problems, the project intends to carry out research in two aspects: in-vehicle network data scheduling algorithms and electronic control unit integrated performance optimization. Firstly, introduced the scheduling algorithm of microprocessor to the vehicle CAN network control system, and proposed DISA intelligent scheduling algorithm, Can effectively reduce the high priority data transmission delay，improve the effectiveness of the automotive vehicle networks when large amounts of data and real-time.Secondly, optimize and manage the network electronic control unit ,while the vehicle CAN bus network transmission of data tend to saturation, with the purpose of reduce network bandwidth usage meanwhile improve the control and transmission performance of the automotive vehicle networks. The research results could provide new scientific data and theoretical basis for the development of netw
