Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not construed as indicating or implying relative importance.
Example 1
Referring to fig. 1, fig. 1 is a schematic flow chart of a vehicle fault monitoring method according to an embodiment of the present disclosure. The vehicle fault monitoring method comprises the following steps:
s101, acquiring all relevant vehicle fault summary information of the target vehicle.
In the embodiment, the method can classify and comb out all relevant faults of the current vehicle in advance, for example, the driving class is classified into 01-020, the charging class fault is classified into 021-050, and the temperature control class fault is classified into 051-070.
In this embodiment, the method may number each fault one by one, for example, 001: limited lost motor communication travel; 021: stopping charging due to the fault of a charger; 051: rapid cooling due to compressor failure, etc.
In this embodiment, the method may monitor a current failure occurrence condition in the controller, and if a failure occurs, send a corresponding failure number to the Tbox through the CAN bus.
And S102, determining all vehicle faults according to the vehicle fault summary information.
And S103, numbering each vehicle fault to obtain a fault number corresponding to each vehicle fault.
And S104, constructing and storing a fault number library according to the vehicle fault and the fault number.
S105, judging whether the target vehicle has a fault, if so, executing a step S106; if not, the flow is ended.
S106, vehicle abnormal data of the target vehicle are detected.
In this embodiment, the abnormal data may be an abnormal signal of the electronic lock switch (the vehicle driving door is not closed), a temperature of the charging terminal (an abnormal temperature is too high), or the like.
And S107, determining a target fault number corresponding to the vehicle abnormal data according to the fault number library.
And S108, when the number of the target fault numbers is not less than two, determining the sending sequence of the fault numbers.
In this embodiment, when a plurality of faults occur, the method causes the plurality of fault numbers to be sent intermittently and continuously until the faults disappear. For example, when the failure numbers 1 and 5 occur simultaneously, the number 1 of 1s is sent first, and then the number 5 of 1s is sent again, and so on.
And S109, intermittently and continuously sending the target fault number to the Internet of vehicles system of the target vehicle through the CAN bus according to the sending sequence, so that the Internet of vehicles system determines the specific vehicle fault according to the target fault number and the fault number library and carries out fault processing according to the specific vehicle fault.
As an optional implementation manner, when the number of the target fault numbers is one, the target fault numbers are continuously sent to the internet of vehicles system of the target vehicle through the CAN bus, so that the internet of vehicles system determines a specific vehicle fault according to the target fault number and the fault number library and performs fault processing according to the specific vehicle fault.
S110, judging whether the abnormal data of the vehicle disappear, if so, executing a step S111; if not, the flow is ended.
And S111, stopping sending the target fault number.
In this embodiment, the method may be implemented by the vehicle control unit, the Tbox, and the background big data system. The vehicle control unit sends related fault signals to the Tbox in a CAN bus mode, and then the Tbox further uploads the fault signals to the background big data system so that the background big data system CAN monitor and/or perform statistical analysis on fault states.
In this embodiment, the execution subject of the method may be a computing device such as a computer and a server, and is not limited in this embodiment.
In this embodiment, an execution subject of the method may also be an intelligent device such as a smart phone and a tablet computer, which is not limited in this embodiment.
It can be seen that, by implementing the vehicle fault monitoring method described in this embodiment, the specific fault information of the current vehicle can be known simply through the background according to the received serial number; meanwhile, the method can also specifically count the frequency of occurrence of each number in a certain period of time based on the background, so as to obtain the probability of occurrence of the fault in practice; in addition, whether the trigger condition related to the fault is reasonable can be further analyzed by combining the state information uploaded by other backgrounds, so that the related condition of fault detection is optimized. Finally, the method can also obtain the incidence relation between the faults by counting which fault numbers are reported simultaneously in a certain time period, and the money day provides reference for scheme design and software development.
