This invention discloses a cockpit-driving fusion redundancy system and method based on dynamic resource scheduling. The system includes an intelligent driving domain controller, an intelligent cockpit domain controller, environmental perception sensors, an intelligent sensor hub, a shared memory pool, and a dynamic resource scheduling kernel. The intelligent sensor hub sends sensor data to the intelligent driving domain controller and the intelligent cockpit domain controller via a first data channel (raw data) and a second data channel (feature data), respectively, achieving perception redundancy. The intelligent driving domain controller writes the intermediate perception feature data generated during processing into the shared memory pool. The dynamic resource scheduling kernel virtualizes the computing resources of the two domain controllers into a unified resource pool and triggers resource reallocation when an anomaly is detected in the intelligent driving domain controller, dynamically scheduling computing power to the intelligent cockpit domain controller. This invention solves the problems of single perception dimension, high takeover latency, and low resource utilization in existing redundancy schemes, achieving seamless and secure takeover with high reliability, low latency, and high resource utilization.
