2、时监控一个电机。第三个节点的 ID 不同于第二个 CAN 节点,监控 另一个电机。整个系统已经完成并调试通过,测试证明完全符合车上通信网络的 需要。 针对实际应用,提出了一个在摩托车中应用 CAN 技术的解决方案,分析了方 案的特点及工作原理,并完成了初步设计。 对包括 CAN 总线的汽车电控系统研发的步骤、方法以及规律性等进行了探 索,并为我校本科教学中开设相关实验进行了准备工作,提出了具体的设想与方 案。 关键词 汽车 电子控制 CAN 总线 通信 网络 毕 业 设 计 说 明 书 ( 论 文 ) 外 文 摘 要毕 业 设 计 说 明 书 ( 论 文 ) 外 文 摘 要 Title Tit
3、le Study of Vehicles CAN-bus Technique AbstractAbstract Vehicles CAN-bus technique which is in quick development is thorough studied. A typical and operable vehicles electrical control system is designed and developed and the system includes the CAN-bus, the electrical unit and the control component
4、 etc. Three nodes in the system communicate through a CAN-bus. The system uses commands from a CAN node and sends this message through a CAN-bus to other two CAN nodes. They are controlling a DC motor separately. The first CAN node acts like a user control panel. It monitors all user inputs and disp
5、lays the real time motor speed. The second CAN node is responsible for generating various signals for motor control, and responsible for monitoring the feedback signal and relays its data to the first CAN node. The third node runs like the second CAN node, but the ID is different form the second CAN
6、 node. The whole system was already completed and can properly operate. More important, the system verifies that the CAN-bus can meet the demand of the communication in vehicle completely. Aiming at the practical application, a solution for applying the technique of CAN-bus in motorcycle was put forward, its characteristics and work principles are analyzed, and the preliminary design is done. The development procedure, method and rules etc. of vehicles electrical control system t
