Vehicle-mounted end of comprehensive vehicle fault detection system and data processing method of same

Abstract

The invention discloses a vehicle-mounted end of a comprehensive vehicle fault detection system. The vehicle-mounted end communicates with cloud equipment through a network, wherein the vehicle-mounted end comprises a monitoring module, a memory and a log recording module, wherein the monitoring module monitors a monitoring point and acquires state information in real time; and the log recording module records the state information in the memory of the vehicle-mounted end in a preset log format. The invention further discloses a data processing method based on the vehicle-mounted end. The vehicle-mounted end of the comprehensive vehicle fault detection system and the data processing method of the vehicle-mounted end disclosed by the invention can effectively find out various problems of a vehicle in time, and also can summarize and comprehensively analyze the various problems of the vehicle.

Description

technical field [0001] The invention relates to a vehicle fault detection technology, in particular to a vehicle-mounted terminal of a comprehensive vehicle fault detection system and a data processing method thereof. Background technique [0002] Since the development of automobiles, the rapid development is automobile electrical appliances and electronic control technology. During the driving process of the vehicle, the vehicle will inevitably break down. With the improvement of vehicle technical equipment level, the difficulty of repair is also increasing. The main factor restricting it is the lack of diagnostic equipment. The current vehicle fault self-inspection and diagnosis methods mainly include: [0003] 1. Through traditional manual services [0004] This method explains the location of the failure and the current location of the vehicle to the technician, and waits for the on-site rescue of the technician, which provides a solution for the driver to a certain ...

AI Technical Summary

Problems solved by technology

[0004] This method explains the location of the failure and the current location of the vehicle to the technician, and waits for the on-site rescue of the technician, which provides a solution for the driver to a certain extent. If the functional system and structural components are not clear, it is difficult to clearly describe the location and condition of the fault, which will bring inconvenience to the technicians to deal with the problem; The time of the faulty vehicle, thus delaying the repair time

[0006] This method can only provide help to users in vehicle fault detection and processing to a certain extent, and its disadvantages are: there are various types of vehicle fault detectors on the market now, and the operation is complicated, and it is difficult for users to choose and use; for novice drivers Due to the ambiguity of the functional systems of the vehicle, the location of structural components, etc., and the current fault detectors on the market can only detect faults, without the guidance of relevant personnel, it is difficult for users to give corresponding solutions, so they cannot Do the repairs yourself

[0007] It can be seen that the vehicle fault detection method in the prior art cannot detect various problems of the vehicle in a timely and effective manner, nor can it effectively summarize and comprehensively analyze the problems of the vehicle

[0008] In addition, the above traditional methods can only be detected and processed after the fault is known to the user

However, many vehicle problems often have various abnormalities inside the car body before the customer finds out, and such abnormalities are often beyond the user's understanding

Therefore, the vehicle failure detection method and device of the prior art obviously can't play the role of preventing micro-duration

[0009] On the other hand, for vehicles of the same model, many failures are often due to flaws in the vehicle design, so vehicles of the same model will generally have the same problems and solutions

Apparently, the above-mentioned vehicle fault detection method or device in the prior art is also unable to summarize and analyze the same or similar problems and provide a standardized solution based on the actual situation of multiple individual vehicles
