Abstract
A vehicle sensor data processing method implemented by a vehicle sensor data processing system includes: the vehicle sensor data processing system processes and fuses, by using a plurality of levels of control units, a signal sensed by a sensor, and a higher-level control unit makes a control decision based on received data of a plurality of types or a plurality of processing levels. In addition, a priority of a sensor may be further configured based on a vehicle function that needs to be implemented by the system, thereby implementing more stable and reliable vehicle control and ensuring safe driving while satisfying a delay requirement.
