Forelectric vehicles,the mileage is very important and critical,it is an important way to save energy that reduces the controller energy consumption effectively under the non-operating state.In order to ensure that each node controller of the distributed CAN network is working properly,and manage network resources effectively,so as well to reduce the energy consumptions of CAN controllers after the vehicle is in stationary,when designing the network of whole vehicle,we should take the CAN network manage-ment into consideration.OSEK network management standards can effectively ensure that all nodes in real-time,reliable communica-tion.Apply OSEK network management to the design of electric vehicle CAN network,it can allocate network resources effectively,coordinate all controllers to work together efficiently,supervise the status of each nodes in real-time,and ensure the network work op-erate normally and sterilely as well.The practical application shows,OSEK network management can reduce the energy consumption af-ter key off.At the same time,we designed a suit of test verification for the network management mechanism to ensure its normal opera-tion.
