基于OSEK标准的整车CAN网络管理设计及测试验证
|
摘要
为了有效地管理网络资源,降低控制器在车辆停止工作后的能源消耗,在整车网络设计中需增加CAN网络管理。OSEK网络管理标准能够有效地保证各个节点实时、可靠通信,能够满足CAN网络对实时性、可靠性的要求;在整车CAN网络设计中增加OSEK网络管理,能够在保证网络正常可靠运行的情况下,有效地分配网络资源,协调各控制器高效工作,并且能够实时监督各节点运行状态。实际应用表明,OSEK网络管理在整车CAN网络中能够协调各控制器正常工作,监督整车网络运行状态,降低能源消耗。最后设计一套有效的测试方法,能够对整车网络管理协调的有效性进行核查。测试结果表明,整车网络管理设计能满足整车CAN网络性能要求。
In order to better manage network resources and reduce the energy consumptions of CAN controllers after the vehicle is stationary,when design the network of whole vehicle,it is necessary to take the CAN network management into consideration.OSEK network management standards could effectively ensure that all nodes are in real-time,reliable communication,which satisfies the requirements on real-time and reliability for CAN network.By applying OSEK network management to the design of vehicle CAN network,it can allocation network resources effectively,coordinate all controllers to work together efficiently,and supervise the status of each nodes in real-time.The practical application indicates that OSEK network management in the vehicle CAN network is capable of coordinating the work,monitoring network status of vehicle operation and reducing energy consumption.At last,a valid method of testing is designed to verify the effectiveness of the vehicle network management.Test results show that the network management design can meet the requirements of the vehicle CAN network performance.
