Problems solved by technology
When the amount of data is large, it will lead to data accumulation, and the main control processor needs to process the data in sequence according to the receiving time, resulting in insufficient data processing
Especially for important data, if it cannot be processed in time, it may bring security risks
For example, when starting to reverse the car, the main control processor is processing other data, which will cause a delay in the processing of the reversing information, so that the reversing image cannot be started in time, and the safety of reversing cannot be guaranteed, which seriously affects the user experience

The invention discloses a vehicle-mounted control system and a data processing method thereof. The method comprises the steps that a master control processor adds received data into corresponding priority queues, wherein the priority queues at least include a high-priority queue and a low-priority queue; and the master control processor processes the data in all the priority queues sequentially according to the high-to-low order of priorities. According to the data processing method of the vehicle-mounted control system in the embodiment, the received data is grouped and added into different priority queues, the data in all the priority queues is processed sequentially according to the high-to-low order of the priorities, therefore, important data can be processed first, the real-time performance of important data processing is improved, blockage of the important data is avoided, the safety of vehicles is improved, and user experience is improved.
Description
technical field [0001] The invention relates to the field of vehicle technology, in particular to a vehicle control system and a data processing method thereof. Background technique [0002] When the vehicle is running, the main control processor of the vehicle control system receives and processes the data sent by the microprocessor (Micro Control Unit, MCU) in real time. When the amount of data is large, it will lead to data accumulation, and the main control processor needs to process the data in sequence according to the receiving time, resulting in insufficient timely data processing. Especially for important data, if it cannot be processed in time, it may bring security risks. For example, when the car is reversing, the main control processor is processing other data, which will cause a delay in the processing of the reversing information, so that the reversing image cannot be started in time, and the safety of reversing cannot be guaranteed, which seriously affects t...
