In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In the embodiment of the invention, a vehicle diagnosis device receives a diagnosis request sent by application-side equipment and sends diagnosis task selection data to the application-side equipment according to the diagnosis request, so that the application-side equipment can load a diagnosis task selection interface according to the diagnosis task selection data; sending a diagnosis task selection instruction triggered in the diagnosis task selection interface by a user to a vehicle diagnosis device, calling an interface function by the vehicle diagnosis device according to the diagnosis task selection instruction, and carrying out information interaction with an electric control system of a vehicle to obtain diagnosis data returned by the electric control system; and then sending the diagnosis result corresponding to the diagnosis data to application end equipment for displaying, and completing the diagnosis of the vehicle fault.
In order to illustrate the technical solution of the present invention, the following description will be given by way of specific examples. Before explaining a specific embodiment, first, fig. 1 shows an interactive schematic diagram of vehicle diagnosis provided by an embodiment of the present invention, which includes an application-side device 101, a vehicle diagnosis box 102 and an electronic control system 103 of a vehicle; the application terminal device 101 comprises a Personal Computer (PC), a tablet computer and a smart phone; the application device 101 is installed with a web browser. The vehicle diagnostic box includes a vehicle diagnostic device.
The vehicle electronic Control system 103 mainly includes an ecu (electronic Control unit) electronic Control unit, which is composed of a microprocessor (CPU), a memory (ROM, RAM), an input/output interface (I/O), an analog-to-digital converter (a/D), and a large-scale integrated circuit for shaping, driving, and the like. In addition to the application to an engine system, an ECU in an automobile may be applied to many other places, for example, an antilock brake system, a four-wheel drive system, an active suspension system, an airbag system, an air conditioning system, an instrument system, etc. may be provided with the respective ECUs. The ECU generally has the functions of fault self-diagnosis and protection, when a system has faults, fault information can be automatically recorded in the RAM, and a user utilizes the diagnosis box to be connected with an OBD interface of the automobile through an OBD connecting line to read ECU data. Specifically, an On-Board Diagnostic (OBD) system is connected to the ECU, and is used to monitor the operating state of the vehicle in real time, and to immediately issue a warning once a situation that may cause a vehicle failure is found. For example, when the system malfunctions, a malfunction lamp or a check engine warning lamp is turned on. And then, a standard diagnostic instrument, such as a diagnostic box, is connected with the OBD diagnostic interface, so that fault information can be read in the form of fault codes, and maintenance personnel can accurately determine the nature and the position of a fault according to the prompt of the fault codes. Great convenience is provided for monitoring and diagnosis of the vehicle.
Fig. 2 shows a specific implementation flow of a vehicle diagnosis method provided by an embodiment of the invention, which is executed by the vehicle diagnosis device and is suitable for a vehicle fault diagnosis situation. The vehicle diagnosis device is integrated in the diagnosis box and can be realized through software and/or hardware. Specifically, the method includes steps S201 to S204.
In S201, a diagnosis request sent by an application device is received, and diagnosis task selection data is sent to the application device according to the diagnosis request, where the diagnosis task selection data is used to instruct the application device to load a diagnosis task selection interface.
The diagnosis task selection data is diagnosis task selection data pre-stored on the vehicle diagnosis device and comprises vehicle system selection data, vehicle type selection data and diagnosis function selection data.
In some embodiments of the present invention, the receiving a diagnosis request sent by an application device, and sending diagnosis task selection data to the application device according to the diagnosis request includes: connecting with the application terminal equipment; the method comprises the steps of receiving a diagnosis request sent by a user through a browser of application end equipment, and sending vehicle series selection data, vehicle type selection data and diagnosis function selection data to the application end equipment according to the diagnosis request.
Specifically, when diagnosing a vehicle failure, first, the application-side device is to establish a connection with the vehicle diagnostic apparatus.
For example, the application terminal device starts a wireless signal search function, and establishes wireless connection with the vehicle diagnosis device by searching for a WIFI hotspot of the vehicle diagnosis device. The WIFI hotspot name of the vehicle diagnosis device can be a serial number of the vehicle diagnosis device, and the serial number is used for uniquely identifying the vehicle diagnosis box, so that the application terminal equipment can select the vehicle diagnosis box to be connected conveniently. It should be noted that, in other embodiments, the application device and the vehicle diagnosis box may also be connected by bluetooth or the like.
After the application terminal equipment is connected with the vehicle diagnosis device, a user needs to perform selection operation of a diagnosis task to diagnose the vehicle.
Specifically, a diagnosis request is first sent to the vehicle diagnosis apparatus through the application device, for example, a browser of the application device sends the diagnosis request to the vehicle diagnosis apparatus. For another example, the user inputs an access address of the vehicle diagnosis box on a WEB browser of the application end device, and sends the diagnosis request to the vehicle diagnosis device by using an HTTP protocol, where the access address is a fixed address: html, so that the vehicle diagnosis device sends diagnosis task selection data to the application terminal equipment according to the diagnosis request, and further the application terminal equipment loads a diagnosis task selection interface according to the diagnosis task selection data.
In S202, a diagnosis task selection instruction sent by the application device is received; the diagnostic task selection instruction is triggered by a user in the diagnostic task selection interface.
The vehicle diagnosis device sends diagnosis task selection data to the application terminal equipment according to the diagnosis request, and then displays a diagnosis task selection interface on a browser of the application terminal equipment; and enabling the user to select the diagnosis task data on the diagnosis task selection interface. For example, the user selects the type of the vehicle system to be subjected to vehicle fault diagnosis on the diagnosis task selection interface, where the vehicle system type includes BENZ, BMW, VOLVO, and the like, then selects the vehicle model under the vehicle system, such as BENZ \ S350, BMW \325, and then selects the function to be diagnosed, i.e., the diagnosis task, such as reading a fault code, clearing the fault code, reading a data stream, and the like. At this time, the application terminal device generates a diagnosis task selection instruction carrying the vehicle type, the vehicle model and the diagnosis task according to the selection operation of the user on the diagnosis task selection interface, and sends the diagnosis task selection instruction to the vehicle diagnosis device.
In S203, an interface function is called according to the diagnosis task selection instruction, information interaction is performed with an electronic control system of the vehicle, and diagnosis data returned by the electronic control system is acquired.
Specifically, after receiving a diagnosis task selection instruction triggered by a user on the application terminal device, the vehicle diagnosis device analyzes the diagnosis task selection instruction to obtain a vehicle type, a vehicle model and a diagnosis task carried in the diagnosis task selection instruction, and then realizes the diagnosis task by calling an interface function.
For example, when the diagnostic task selected by the user is to read a fault code, the diagnostic task includes the steps of setting a communication parameter corresponding to the system, entering the system, reading a system fault code, exiting the system, and the like, and each step is implemented by calling an interface function in an interface library.
The interface function comprises an interface function based on a J2534 standard formulated by SAE (society of automotive Engineers) of America and an ISO22900-D-PDUI standard interface function formulated by ISO of the International organization for standardization. The system comprises an engine system, an anti-lock brake system, a four-wheel drive system, an active suspension system, an air bag system, an air conditioning system and an instrument system, wherein communication parameters of the setting system comprise communication pins, baud rate, system ID and protocol type of the setting system, and the reading of the system fault code comprises sending of a fault code reading command and receiving of fault code information returned by the system.
The step of calling an interface function according to the diagnosis task selection instruction and performing information interaction with an electric control system of the vehicle comprises the following steps: calling an interface function to set communication parameters of the bus transceiver; and information interaction is carried out with an electric control system of the vehicle through the bus transceiver.
For example, the vehicle diagnostic device sets a communication pin of a bus transceiver to be 6, a baud rate to be 500K, and a system ID to be FC00 according to a system protocol of a vehicle electronic control system to be diagnosed in the diagnostic task, then sends a system entering command 1001 to the system FC00, then sends the fault code reading command 190208 to the system FC00, receives diagnostic data 081122334455667788 returned by the system FC00, and finally sends a system exiting command to the system FC00, thereby completing information interaction between the vehicle diagnostic device and the vehicle electronic control system.
That is, a user directly accesses a diagnosis task selection interface in a storage and diagnosis box through a WEB browser on application-side equipment, selects a vehicle type, a vehicle model and a diagnosis task in the diagnosis selection interface, and calls an interface function through the diagnosis box according to a diagnosis task selection instruction carrying the vehicle type, the vehicle model and the diagnosis task to finish the diagnosis of the vehicle.
In S104, the diagnostic data is processed to obtain a diagnostic result, and the diagnostic result is sent to the application device for display.
In some embodiments of the invention, the processing the diagnostic data to obtain the diagnostic result comprises: and processing the diagnosis data through a diagnosis algorithm to obtain a diagnosis result corresponding to the diagnosis data. The diagnosis result comprises the number of the system fault code and the state of the fault code.
For example, if the diagnostic data returned by the system FC00 is 081122334455667788, it is determined that the first byte "08" in the diagnostic data represents 8 bytes of byte number of the diagnostic data according to a preset diagnostic algorithm, each 4 bytes "11223344" and "55667788" represents a fault code, the first 3 bytes of the fault code represent the number of the fault code, the 4 th byte of the fault code represents the state of the fault code, the diagnostic results corresponding to the diagnostic data "081122334455667788" are P112233 and P6677, where P represents that the fault code is a fault code of an engine, and the P112233 and P556677 represent that the engine of the vehicle has a fault represented by the fault code. Additionally, the status of the fault code includes: historical fault codes and current fault codes; after the vehicle maintenance personnel can conveniently perform vehicle maintenance, when the vehicle is diagnosed again, whether the vehicle fault is eliminated or not can be judged.
In the implementation mode of the invention, the application terminal equipment only needs to be provided with a WEB browser, the WEB page of the diagnosis box is accessed through the WEB browser, the diagnosis task selection instruction can be triggered by a user on the application terminal equipment, and then the diagnosis box calls an interface function according to the diagnosis task selection instruction to diagnose the vehicle. The diagnosis software is not required to be installed on the application terminal equipment, the diagnosis of the vehicle is irrelevant to the system configuration and the operating system type of the application terminal equipment, and all data are stored in the diagnosis box, so that the problems of high development difficulty and high development cost of the diagnosis software in the prior art are solved, and the vehicle diagnosis cost is reduced.
