Problems solved by technology
[0004] The existing vehicle remote diagnosis judges the possible failure of the vehicle by analyzing the running status of the parts on the vehicle. It is an isolated remote diagnosis for a single vehicle. Due to problems in component design or manufacturing, the existing data server can only provide diagnostic strategies based on the problem of a single vehicle, and cannot provide data for the improvement of component design or manufacturing. Therefore, the data utilization rate in the data server is low

Embodiment Construction
[0051] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0052] figure 1It shows a schematic structural diagram of a vehicle remote diagnosis system 00 involved in a vehicle remote diagnosis method. The vehicle remote diagnosis system 00 includes: a vehicle-mounted terminal 001, a data server 002, and stored in the data server 002 are registered vehicles. Base data for the individual components in the assembly. The vehicle-mounted terminal 001 sends the running status data of the monitored parts in the vehicle to the data server 002, and the data server 002 judges whether the parts are faulty based on the running status data, and provides diagnostic strategies for specific faults. Wherein, the components to be monitored in the vehicle may be electronic components such as resistors, capacito...

The invention discloses a vehicle remote diagnosis method and equipment, belonging to the field of vehicle remote diagnosis. The method includes: judging whether the first component fails by comparing the operating state data of the first component with the basic data of the first component; when the first component fails, determining the type of the failure; when the type of the failure For manufacturing faults or design faults, adding the operating state data and basic data of the first component to the first fault database, the first fault database stores the operating state data of components of the same type and the same fault type as the first component and basic data. It can solve the problem that data cannot be effectively provided for the improvement of parts design or manufacturing, and can effectively provide data for the improvement of parts design or manufacturing, and the effect of higher data utilization in the data server. The invention is used for vehicle remote diagnosis.
Description
technical field [0001] The invention relates to the field of vehicle remote diagnosis, in particular to a vehicle remote diagnosis method and equipment. Background technique [0002] With the development of vehicle control technology, the equipment controlled by mechanical methods on the vehicle is gradually replaced by automatic equipment. Each automatic equipment is usually equipped with an electronic control unit. The electronic control unit has self-diagnosis ability and can receive It is used to monitor the signal sent by the sensor of the preset component, and then analyze it to detect the working condition of the preset component, so as to judge the possible failure of the vehicle. [0003] In the prior art, the vehicle can also perform remote diagnosis. The electronic control unit on the vehicle can first send the operating status data of the components carried in the received signal to the vehicle terminal, and the vehicle terminal sends the data remotely through wi...
