| 摘 要： | 根据控制局域网络（CAN）的特点及应用要求，提出一种新的动态调度协议（DSP），通过动态选择时间间隙调度信息，同时考虑实时数据的重传机制，并在此基础上介绍基于CAN总线的实时DSP应用算法，该算法不仅能满足CAN网络中实时应用系统的性能要求，还能充分利用CAN网络带宽。实验结果表明，该算法降低了传输请求程序的平均信号延迟，同时提高了网络利用率。

| Abstract: | According to the characteristics and the corresponding requirements of Controller Area Network(CAN), this paper proposes a novel Dynamic Scheduling Protocol(DSP), which dynamically selects the time slots of CAN bus for the real-life applications, and considers the mechanism to re-transmit real-time data. On basis of this, an algorithm of real-time DSP application based on CAN bus is introduced, which not only meets the real-time requirements of CAN applications, but also explores the bandwidth of CAN.
