High-reliability resource scheduling method of central domain controller, controller and medium

By pooling M-core resources in the central domain controller and flexibly scheduling them according to task response time, the problem of response time not meeting safety level requirements caused by M-core binding relationship is solved, thereby improving the reliability of task execution and the safety of the whole vehicle.

AI Technical Summary

Technical Problem

In sudden high-load scenarios, the binding relationship between the M core and tasks in the traditional central domain controller causes the worst-case response time of critical tasks to fail to meet the functional safety level requirements, resulting in poor overall vehicle safety.

Method used

By abstracting the resources of the M-core cluster into a unified resource pool, tasks are flexibly scheduled to matching processing units based on their response time. Processing strategies and scheduling methods corresponding to different response time ranges are adopted, including the division of the basic resource pool and the elastic resource pool, to ensure exclusive processing of urgent tasks and flexible allocation of other tasks.

Benefits of technology

This improves the reliability of task execution and the safety of the entire vehicle, and provides suitable hardware resources to support tasks with different real-time requirements, thereby improving system resource utilization and overall vehicle safety.

Abstract

The embodiment of the invention provides a high-reliability resource scheduling method of a central domain controller, the controller and a medium. The method comprises the steps of obtaining required response time of a to-be-processed task in response to the received to-be-processed task; according to the required response time and a preset high-reliability resource scheduling strategy, a target processing unit corresponding to the to-be-processed task is determined, the high-reliability resource scheduling strategy comprises processing strategies corresponding to different response time ranges, and each processing strategy is used for indicating the processing unit of the task in the corresponding response time range. The method is used for improving the adaptability of resource allocation of different response time demand tasks, so that the task execution reliability of the controller and the safety of the whole vehicle are improved.
