In daily use of an automobile, vehicle faults, such as power domain faults, chassis domain faults, body domain faults, power supply system faults, network faults (namely, the automobile does not have the capability of accessing the internet) and the like, inevitably occur, wherein especially hidden faults existing in the automobile, an owner of the automobile is difficult to find in time, and a driver can find the hidden faults only when the faults are exposed and normal use of the automobile is influenced, obviously, potential safety hazards exist.
In order to effectively solve the vehicle failure in time to ensure safe driving, two methods are generally adopted in the prior art: first, the vehicle is taken to a 4S store and the vehicle is detected and troubleshot by a professional on site, and this process usually requires the vehicle to be taken apart and the vehicle status information to be detected using some expensive tool.
Obviously, this way, both wastes the time and effort of the owner and the maintenance personnel, and may cause other misoperations during the dismantling of the car, i.e. being too costly and unreliable.
The second is, for example, the patent with the publication number CN209570850U, entitled vehicle remote fault diagnosis system, which sends an instruction to a vehicle-mounted T-Box in a wireless 3G communication transmission manner through a background server, and when the T-Box receives the instruction, acquires a vehicle fault code through a vehicle CAN bus, and forwards the fault code to the background server through the T-Box, and then analyzes the fault code and displays the fault code representing a corresponding fault on a diagnosis platform.
Obviously, the method can be used for remotely diagnosing the vehicle fault, compared with the method that a driver maintains the vehicle at a maintenance point after finding the fault, the method improves the safety, reduces maintenance cost and time cost, and further improves the after-sales satisfaction degree of a vehicle owner, however, the fault reporting of the method depends on the networking capacity of the vehicle-mounted T-Box, if the vehicle fault is a power supply system fault, the T-Box cannot be normally supplied with power, or the T-Box cannot be networked due to the vehicle network fault, and the remote diagnosis platform cannot clearly acquire the fault reason.
