Description

Technical Field

[0001] The present invention relates to the technical field of vehicle remote diagnosis and control, and in particular to a vehicle remote diagnosis control method and device based on vehicle fault codes. Background Art

[0002] With the development of urbanization and mechanization of sanitation operations, new energy sanitation vehicles have been rapidly developed for the cleaning of urban roads, supported by national and local policies. New energy vehicles are very different from traditional vehicles in terms of power systems, energy management and maintenance requirements. Therefore, more advanced technologies are needed to monitor and manage the operating status of these vehicles, detect potential safety issues in a timely manner, and improve vehicle safety through remote diagnosis and even remote control. With more and more frequent use, the requirements for vehicle intelligence, convenience and service experience are constantly increasing, and customers hope to provide more personalized and convenient services, such as remote diagnosis, remote braking, remote control, etc. With the full coverage of the national standard 32960 protocol, new energy sanitation vehicles continue to introduce new technologies and new functions in order to stand out in the fierce market competition. Remote diagnosis and control technology has become an important aspect of improving product competitiveness, and it is also an important direction for the transformation and upgrading of the automobile industry and the development of intelligence.

[0003] At present, the remote monitoring of new energy sanitation vehicle faults in the market is relatively simple, and 90% of vehicles only use the general alarm data in the national standard 32960. This data can reflect the characterization phenomenon of vehicle faults, but cannot reflect the specific cause of vehicle faults, and cannot provide decisive support for the diagnosis and cause analysis of vehicle faults. The other part is based on the whole vehicle parameters uploaded by the national standard, such as voltage, current, brake signal, battery cell temperature, etc., combined with the general alarm data to infer the cause of the fault, so as to reversely lock the vehicle fault component or the inducing cause. This method can remotely diagnose vehicle faults to a certain extent, but the national standard data is processed data with data distortion, and there is no need for parameters; in addition, this method requires additional time and resources, and further requires expert models to analyze and integrate parameters to draw conclusions. There is a certain lag, which can diagnose some fault causes, but it also cannot provide decisive support for locking fault components. A few vehicle manufacturers with technical conditions will develop VCU programs on their own, integrate the whole vehicle CAN network data, expand vehicle data on the basis of the national standard, and provide accurate and comprehensive data for fault analysis and diagnosis, which can fully support vehicle remote fault analysis and diagnosis at the data level. Although this method has certain technical barriers, it can provide decisive support for fault locking at the data level. On the other hand, a large amount of data will consume a lot of traffic, which has a certain economic burden. At the same time, fault analysis also has a certain lag.

[0004] Therefore, how to invent a vehicle remote diagnosis and control method that can solve the problems of decisive support, lag, and sharp increase in traffic in the current remote diagnosis of new energy sanitation vehicle faults has become an urgent problem to be solved. Summary of the invention

[0005] To this end, the present invention provides a vehicle remote diagnosis control method and device based on vehicle fault codes, which can solve the problems of decisive support, hysteresis, and sharp increase in traffic in the current remote diagnosis of new energy sanitation vehicle faults, improve the accuracy of remote fault diagnosis, improve the efficiency of fault locking, and quickly and accurately lock the faulty components or the inducing causes.
