摘　　要：采用MC9S12C32型微控制器的CAN总线技术,以S2629型卡车为研究对象,对各低速用电负载进行分类,并提出集中控制节点总体设计方案,设计节点硬件和控制软件,进一步优化低速总线负载的接线与控制.通过真实节点及仿真软件(CANoe)对该CAN总线系统进行分析,使用CANScope工具对智能节点的信号品质及信号稳定性进行检测和统计学分析.结果表明,此总线系统各个位置叠加效果一致性及系统信号品质较好,可有效提高负载的集成性和可靠性.Based on CAN bus technology related to Motorola's micro-controller MC9S12C32 and the S26-type trucks as the research object,low-power consumption loads are classified and the solution of centralized monitoring is given. The centralized control node integrity design is proposed and the hardware solution for the node and the node-control software program are introduced. Based on the application of the CAN bus,the wiring and controlling of the low-speed bus loads are further optimized. The CAN bus system is analyzed through real nodes and stimulation software (CANoe),and the signal quality and reliability of intelligent nodes are tested and analyzed statistically by CANScope tools. It's been proved that the proposed solution could increase the integrity and reliability of the loads efficiently and therefore reduce the costs.
