| Abstract: | A linear-fit algorithm used for on-board vehicle data storage is presented,which is implemented by using a SQL database based on ARM-Linux operating system.The results show that the compression performance is very good for larger numbers of successive data and the number of data would reduce rapidly.In particular,a high compression ratio can be gained by the proposed method for low data fluctuation and less sample interval. |
