The number of active safety sensors in an automotive system is increasing exponentially. However, there is no international standard or de facto standard for active safety sensor networks. Therefore, each sensor manufacturer uses a different network protocol and makes vendor-specific command protocols for their sensors. This makes active safety sensors difficult to use and increases the development costs for intelligent automotive systems using active safety sensors. Thus, we propose an Ethernet-based integrated network protocol for solving the above problems. The proposed network protocol includes a physical layer, a data link layer, a communication layer, a service layer and an application layer. To verify this proposal, we implement an embedded system that supports the proposed network and measures the synchronization performance and cycle time.
