The K-Means Clustering Methods Applied in the Message Scheduling Methods of Flexray Communication Network Based on the Embedded Flexray Node

The Flex Ray communication technology is fast, stable, and fault-tolerant, and can satisfy the needs of advanced vehicle control systems. However, few studies on the Flex Ray communication protocol have analyzed Flex Ray event message response time or verified timing performance. Therefore, this study presented one method for Flex Ray message scheduling to enhance transmission performance within the overall communication network based on the 32-bits embedded Flex Ray node. The K-means clustering method is utilized to reduce network usage within the overall Flex Ray communication network, thus enhancing the safety of the communication network.
