AI Technical Summary

Technical Problem

Existing vehicle network technologies, such as CAN, FlexRay, and MOST-based networks, struggle to support the higher data rates required by telematics and infotainment systems, leading to unnecessary resource reservation waste when communication paths are not used, which affects network efficiency.

Method used

A method for releasing resource reservations in a vehicle network using the Stream Reservation Protocol (SRP) by generating and sending frames with identification information and release indicators, allowing for the efficient release of unused reserved resources, even for higher-priority streams.

Benefits of technology

This approach prevents resource waste and ensures efficient use of network resources by releasing lower-priority reservations for higher-priority streams, thereby improving the overall efficiency of the vehicle network.
