Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle reports fault information to a remote server, then the remote server can perform fault processing, but communication faults prevent timely reporting and processing
Solution Approach 1:
The patent introduces roadside detection devices as intermediaries between faulty vehicles and remote servers. When a vehicle experiences communication failure, roadside detection devices detect and collect fault information from the vehicle, then transmit this information to the remote server, ensuring fault information is not lost even when direct vehicle-server communication fails
Solution Approach 2:
The system performs preliminary fault detection and information collection by roadside detection devices before the fault information can be lost. The detection devices continuously monitor vehicles and are ready to immediately collect and report fault information when detected, preventing information loss that would occur with delayed reporting
2Productivity
If the vehicle reports fault information in real time, then the remote server can timely process faults, but communication faults cause delayed processing and safety hazards
Solution Approach 1:
Roadside detection devices perform preliminary fault detection and information collection immediately when a fault is detected, eliminating the waiting time for the vehicle to initiate reporting. This preliminary action ensures fault information is captured and transmitted without delay, improving processing efficiency while minimizing time loss
Solution Approach 2:
The system establishes a feedback mechanism where roadside detection devices continuously monitor vehicles and immediately transmit fault information to the remote server upon detection. This real-time feedback loop ensures timely fault processing by continuously monitoring and rapidly responding to fault conditions, reducing both time loss and safety hazards
3Reliability
If multiple detection devices are deployed near the vehicle, then fault information can be collected even in communication fault states, but the system complexity increases
Solution Approach 1:
Roadside detection devices are designed with multi-functionality, serving both normal traffic monitoring and fault detection purposes. These devices can detect various vehicle parameters including fault information, communication status, and positional data, reducing the need for specialized equipment and simplifying the overall system architecture while maintaining high detection reliability

AI summary
Implementations of the present specification provide a vehicle fault processing method and apparatus, a device, and a medium. The method includes: determining a position of a target vehicle when fault detection of the target vehicle is triggered; sending a detection instruction to a target detection device corresponding to the target vehicle based on the position, wherein the target detection device is close to the position and capable of detecting the target vehicle; receiving fault information obtained by performing fault detection on the target vehicle through the detection device in response to the detection instruction; and performing fault processing on the target vehicle based on the fault information. In a case where a faulty vehicle is unable to perform fault communication, fault information of the faulty vehicle may be collected by a nearby target detection device, ensuring the fault processing of the vehicle in a communication fault state.
