Study on Dynamic Reconfiguration and Compression Algorithm for Vehicle CAN Bus

为解决汽车智能化网联化带来的车辆CAN总线负载增加的问题,提出了一种针对CAN总线的动态重组压缩算法。该算法采用动态重组的思想对消息的数据字段重新划分、排列和压缩,去除了冗余数据,减少了数据字段的长度。仿真结果表明,与其他算法相比,所提算法的压缩率及实用性更高。

In order to solve the problem of vehicle can bus load increase caused by vehicle intelligent networking,this paper proposes a dynamic reconfiguration compression algorithm for CAN bus.The algorithm adopts the idea of dynamic reorganization to re divide,arrange and compress the data field of the message,which eliminates the redundant data and reduces the length of the data field.Simulation results show that compared with other algorithms,the proposed algorithm has higher compression ratio and practicability.
