Vehicle network systems are becoming increasingly complex by considering all the surrounding environmental factors necessary for driving. As a result, the number of electronic control units and data processing required in the vehicle is increasing, and the risk of falling into an overload state greatly increases. Most scheduling algorithms to process tasks cannot perform well under overload. Even one device can significantly impact the entire system if it causes performance problems. Therefore, providing a load control method for each device is one of the most important tasks. Simply controlling the load by reducing traffic has not been a good solution, and more efficient ways to control the load on the device are required. In this paper, we propose a method for integrating duplicate tasks and reducing the load while complying with thresholds through multi-core-based time-division processing.
