Description
Technical Field
The invention belongs to the technical field of vehicle diagnosis, and particularly relates to a diagnosis method for displaying vehicle diagnosis function nodes on the same interface.
Background
The automobile diagnosis equipment is a special tool specially aiming at automobile detection and maintenance, and the automobile diagnosis equipment in the current market mainly has the functions of fault code reading, data stream reading, actuator testing, system data uploading, flashing, calibration and the like of an automobile electric control unit. When the automobile diagnostic equipment realizes the functions, the communication parameters are required to be used for communicating with the automobile electronic control unit, and the communication parameters comprise communication pins, baud rate, communication mode, communication protocol, communication address and the like. Because the uploading, the flashing and the calibration functions aiming at the same automobile electric control unit generally use communication parameters different from other functions, the uploading, the flashing and the calibration functions aiming at the same automobile electric control unit can be separately placed from other functions by the existing automobile diagnostic equipment on the market, and the uploading, the flashing and the calibration functions aiming at the same automobile electric control unit are displayed in different interfaces on a display screen of the automobile diagnostic equipment.
For the maintenance personnel, if the basic function and the advanced function are both needed to be used in the same maintenance, for example, the data stream of a certain vehicle needs to be read and the electronic control unit system needs to be refreshed, the maintenance personnel needs to find the corresponding basic function node in the diagnostic equipment, quit the node after reading the data stream and find the corresponding refresh node to complete the refresh.
Such an approach mainly suffers from the following disadvantages:
because the diagnostic device does not support the uploading, the flashing and the calibration functions for all the automobile electric control units, the functions supported by the diagnostic device for a certain automobile electric control unit are not all displayed on the same interface, so that the functions supported by the diagnostic device are difficult to judge by maintenance personnel, and the overall maintenance scheme is not easy to determine in advance.
For example, for a specific automobile electric control unit, the diagnostic device only supports the functions of reading data streams and fault codes, and does not support the functions of uploading and writing. Maintenance personnel cannot judge whether the diagnostic equipment supports the flash on the basic function node interface, and may waste time to find the corresponding flash node after the data stream is read.
Placing the base and advanced functions separately can cause maintenance personnel to repeatedly spend time looking for nodes on the diagnostic equipment.
For example, to read a data stream of a certain vehicle and write over an electronic control unit system of the vehicle, a maintenance worker needs to find a corresponding basic function node in the diagnostic equipment, quit the node after completing the operation, find a corresponding writing node, and complete writing over. The tedious node finding and node exiting operations are repeated as maintenance personnel need to jump between the basic and advanced functions multiple times.

In order to solve the technical problems, the invention adopts the following technical scheme:

Each row further includes whether to use a lower computer pin field, and in step S105, when the value of the mode selection field represents a designation, it is determined whether to use the lower computer pin field:
if the scanning of the lower computer is not used, comparing the baud rate of data returned by the electronic control unit when the lower computer of the diagnostic equipment communicates with the vehicle electronic control unit through the scanned communication pins with the configured baud rate of the corresponding diagnostic function in the background database, if the baud rates are the same, the diagnostic equipment uses the scanned communication pins and the baud rate, the communication mode, the communication protocol, the communication address and the initialization command configured in the background database of the corresponding diagnostic function to establish communication with the vehicle electronic control unit, and if the baud rates are different, the diagnostic equipment uses the communication parameters and the initialization command configured in the background database of the corresponding diagnostic function to establish communication with the vehicle electronic control unit;

Drawings
The invention is described in detail below with reference to the following figures and detailed description:
FIG. 1 is a flow chart of an embodiment of the present invention;
FIG. 2 is a schematic diagram of a diagnostic interface of a read data stream function node according to the present invention.
Detailed Description
As shown in fig. 1, a diagnostic method for displaying a vehicle diagnostic function node on the same interface includes:
s101, after a maintenance worker clicks a path node on the diagnosis equipment, the diagnosis equipment uses the communication parameters and the initialization command configured in the background database by the path node to communicate with the vehicle electric control unit, wherein the communication parameters comprise communication pins, baud rate, communication mode, communication protocol and communication address.
S102, the diagnostic equipment receives data returned by the vehicle electric control unit after receiving the communication command, and finds a corresponding diagnostic function list from a background database according to the data, wherein the data and the diagnostic function list are correspondingly configured in the background database in advance, each line of the diagnostic function list corresponds to one diagnostic function of the vehicle electric control unit, and each line comprises a function description field, a mode selection field, a communication pin field, a baud rate field, a communication mode field, a communication protocol field, a communication address field and an initialization command field corresponding to the diagnostic function.
The path nodes are usually self-identification nodes, the diagnostic equipment identifies the electric control units of different models according to data returned by the vehicle electric control units, and then the corresponding diagnostic function list is found from the background database.
And S103, the diagnostic equipment sends an exit command to the diagnostic equipment by using the communication parameters in the step S101, and the communication with the vehicle electronic control unit is disconnected.
The purpose of steps S101 and S102 is only to determine the diagnostic function list corresponding to the electronic control unit, and the subsequent diagnostic function may use different communication parameters to establish communication with the electronic control unit again, so that the communication needs to be disconnected first to avoid affecting the subsequent communication.
S104, the diagnostic equipment selectively displays corresponding function description fields as function nodes on the same interface according to the values of the mode selection fields in the diagnostic function list for the maintenance personnel to click:
if the value of the mode selection field represents the designation, displaying the corresponding function description field; if the value of the mode selection field represents software adaptation, it is determined whether the communication mode used in step S101 is the same as the communication mode configured by the corresponding diagnostic function in the background database, and if so, the corresponding function description field is displayed.
The specification or software adaptation may be directly used as the value of the mode selection field, but may be represented by 0 or 1, respectively.
The step is to solve the problem that some diagnostic functions of the electric control unit can only be realized through a certain communication mode, and the problem that some pins of the electric control unit in an actual automobile are not connected. For example, the whole vehicle calibration function of the electronic control unit EDC17CV54PV1175V115 CAN only be realized through K-wire communication, and by configuring the mode selection field of the whole vehicle calibration function as "specified", the whole vehicle calibration function is displayed on the display of the diagnostic device regardless of whether K-wire communication or CAN-wire communication is used in step 1, and the whole vehicle calibration function CAN be used if the electronic control unit is normally wired on the vehicle. In addition, the fault code function of the electronic control unit CAN be realized by CAN line communication in theory and also CAN be realized by K line communication, but in practice, the CAN line of the electronic control unit may not be connected on the vehicle, and both the mode selection fields of the CAN line fault code function (the communication mode configured in the background database is the CAN line) and the K line fault code function (the communication mode configured in the background database is the K line) are configured as software adaptation, when the K line communication is used in the step 1, the CAN line fault code function is not displayed on the display, so that the fault code function CAN be realized by the communication mode when maintenance personnel enter the vehicle.
In the present embodiment, a plurality of function nodes are displayed in a list form. If one page can not display all the diagnosis function nodes in one interface, the page can be displayed by multiple pages.
S105, when the maintenance personnel click the functional nodes in the functional node list displayed on the diagnostic equipment, the diagnostic equipment selects corresponding communication parameters and an initialization command according to the values of the corresponding mode selection fields to establish communication with the vehicle electronic control unit, and displays a diagnostic interface corresponding to the clicked functional nodes:
if the value of the mode selection field represents a software adaptation, the diagnostic device establishes communication with the vehicle ecu using the communication parameters and the initialization command in step S101.
If the value of the mode selection field represents the designation, the diagnostic device establishes communication with the vehicle electronic control unit using the communication parameters and the initialization command configured in the background database for the corresponding diagnostic function.
Preferably, each row of the diagnosis function list further includes whether to use the lower computer pin field, and in step S105, when the value of the mode selection field represents the designation, it is determined whether to use the lower computer pin field:
if the communication pins of the lower computer are used for representing yes, comparing the baud rate of data returned by the electric control unit when the lower computer of the diagnostic equipment communicates with the vehicle electric control unit through the swept communication pins with the configuration baud rate of the corresponding diagnostic function in the background database, if the baud rates are the same, the diagnostic equipment uses the swept communication pins and the baud rate, the communication mode, the communication protocol, the communication address and the initialization command configured in the background database by the corresponding diagnostic function to establish communication with the vehicle electric control unit, and if the baud rates are different, the diagnostic equipment uses the communication parameters and the initialization command configured in the background database by the corresponding diagnostic function to establish communication with the vehicle electric control unit.
And if the pin field of the lower computer is not used for representing, the diagnostic equipment uses the communication parameters and the initialization command configured in the background database by the corresponding diagnostic function to establish communication with the vehicle electronic control unit.
Because the actual pins used for wiring of the electronic control unit are unknown, the background can be configured with a plurality of pins to try to establish communication according to the actual use possibility sequence, but if the lower computer sweeps effective pins, the pins are the actual communication pins, and the speed can be accurately increased; when a certain specific electronic control unit realizes a certain function by using a fixed communication mode and a communication protocol, the baud rate is determined, if the baud rate of data returned by pins swept by the lower computer is different from the background configuration, the pins of the lower computer are judged to be invalid, and communication with the electronic control unit is tried according to the background configuration sequence.
And S106, when the maintenance personnel inputs an operation instruction to the diagnosis interface, the diagnosis equipment sends a command corresponding to the operation instruction in the diagnosis file corresponding to the clicked functional node to the vehicle electronic control unit by using the communication parameter used in the step S105, and processes the command according to a rule for processing corresponding return data of the vehicle electronic control unit in the diagnosis file.
Taking the read data stream function as an example, as shown in fig. 2, a diagnostic interface of the read data stream function node has a plurality of data stream items for a maintenance person to select, and the maintenance person may perform the following operations as required: clicking a single item to select, fully select, clear, read and store the item as a new category, wherein the operation is to input an operation instruction to the diagnosis interface.
If the battery voltage item is clicked and read, which is equivalent to inputting an operation instruction for reading the battery voltage data stream to the diagnosis interface, the command corresponding to the battery voltage data stream in the diagnosis file corresponding to the data stream reading function node is sent to the vehicle electronic control unit, and the data returned by the vehicle electronic control unit is analyzed according to the corresponding analysis rule in the diagnosis file. The rules are different when different diagnostic functions are performed, the rules are analysis rules for return data when data streams are read, and other commands can be sent to a unit for vehicle electronic control according to different return data when other diagnostic functions are performed.
Preferably, in the present embodiment, the functional nodes with the same function in different vehicle electronic control units and the same diagnostic data used by the corresponding diagnostic interfaces are corresponding to the same diagnostic file in the background database in advance, and the diagnostic data includes the command and the rule in step S106. Therefore, one diagnostic file can be used by the functional nodes of a plurality of diagnostic function lists, diagnostic data and communication parameter data can be separated when a diagnostic equipment provider configures the database, and even if the electronic control units with different communication parameters can use the same diagnostic file when the diagnostic data are the same, the workload of database maintenance is reduced. For example, if the diagnostic data used for the read data stream function of the electronic control unit a is the same as the diagnostic data used for the read data stream function of the electronic control unit B, the same read data stream function diagnostic file is used for both the diagnostic function list 1 of the electronic control unit a and the diagnostic function list 2 of the electronic control unit B.
And step S107, when the maintenance personnel quit the functional nodes, the diagnostic equipment sends a quit command to the vehicle electronic control unit by using the communication parameters used in the step S106, disconnects the communication with the vehicle electronic control unit and returns to the functional node list in the step S105.
The method can display all the diagnosis function nodes of the same electric control unit on the same interface at the same time, so that maintenance personnel can know all the functions supported by the diagnosis equipment aiming at the electric control unit, can plan the whole maintenance scheme in advance, and does not need to repeat the process of selecting the nodes when the maintenance personnel jumps among the functions with different communication parameters, thereby saving time and improving efficiency.
