Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The diagnostic method provided by the application can be applied to the application environment shown in fig. 1. The terminal device 102 communicates with a plurality of controllers 104 through a network, wherein the plurality of controllers are encoded as a controller 1041 and a controller 1042 …, respectively, and the controller 104 n. The terminal device 102 may be, but is not limited to, a diagnostic apparatus, various personal computers, and a notebook computer.
In one embodiment, as shown in fig. 2, the method for diagnosing controllers is implemented by the terminal device 102 interacting with a plurality of controllers 104, and includes the following steps:
step S101: the first diagnostic messages are sent simultaneously to the plurality of controllers.
Specifically, existing diagnostics are all performed for a single controller or the control of the entire network system, and it is not possible to perform diagnostics on a part of controllers quickly and directly. In the present application, a part of the diagnostic functions, i.e. the functions of the individual controllers, are mainly implemented. For example, the vehicle control unit corresponds to a calculation processing function and is provided with a corresponding code 01101111, the engine control unit corresponds to a function of outputting running power and is provided with a corresponding code 00111111, and the like. Referring specifically to table 1, shown below:
TABLE 1 controller function and code correspondence table
Further, the message format of the first diagnostic message in this document is shown in fig. 3, and the data in the data field is the function code corresponding to each controller.
Step S102: and receiving a first diagnosis message sent by the terminal.
Specifically, the plurality of controllers simultaneously receive the first diagnostic message and identify codes in a data field in the first diagnostic message. When the terminal apparatus 102 simultaneously transmits a first diagnostic message to a plurality of controllers (the code in the data field in the first diagnostic message is 00000010), the plurality of controllers recognize the code 00000010 in the first diagnostic message.
Step S103: and if the first byte value in the first diagnostic message is matched with a first preset function value, starting a diagnostic function.
Specifically, the first byte value is the code in the data field. The first preset function value refers to the code value corresponding to the function of the different controller. Different controllers correspond to different functions, and the first preset function values in different controllers are different.
Further, if the code in the data field of the first diagnostic message sent by the terminal device 102 to the plurality of controllers at the same time is 00000010, the plurality of controllers identify and match the code 00000010, and only the first preset function value stored in the controller with the lane keeping function matches 00000010; the first preset function value stored in the controller having no lane keeping function does not match 00000010.
Step S104: and after receiving the diagnosis starting function information fed back by any one of the controllers, sending diagnosis request information to the controller.
Specifically, when a first preset function value stored in the controller having the lane keeping function matches 00000010, the on diagnosis function information is transmitted to the terminal device 102, and after the terminal device 102 receives the on diagnosis function information, the diagnosis request information is transmitted to the controller. The diagnostic information request information may be in the form of binary code, decimal code, and the like, and is not limited specifically.
Step S105: and responding to the request information and feeding back diagnosis starting information to the terminal after receiving the diagnosis request information sent by the terminal.
Step S106: and diagnosing the controller when the diagnosis starting information fed back by the controller is received.
Step S107: and after the diagnosis is finished, if the first byte value in a second diagnosis message sent by the terminal to be received is matched with a second preset function value, the diagnosis function is closed.
Specifically, the format of the second diagnostic packet is the same as that of the first diagnostic packet, and the data field of the second diagnostic packet also stores the function codes corresponding to the controllers, where the function codes correspond to a second preset function value.
Further, the code corresponding to the shutdown diagnostic function of each controller is set to 0X7F (bin: 01111111), when the code in the data field of the second diagnostic packet sent by the terminal 102 to the controller is 01111111, the controller matches the second preset function value with 01111111, and if the second preset function value is matched with the 01111111, the controller executes the shutdown diagnostic function.
Step S108: and sending a second diagnosis message to the controller after the diagnosis completion information fed back by the controller is received, so that the controller executes a diagnosis closing function according to the second diagnosis message.
The method can achieve targeted problem troubleshooting by compiling corresponding numbers for the functions of each controller, and can reduce the bus load in the diagnosis process, improve the diagnosis efficiency and realize quick positioning.
As shown in fig. 4, the present application further provides a diagnostic method applied to the terminal device 102, where the method includes:
step S201: simultaneously sending first diagnosis messages to a plurality of controllers;
step S202: after receiving the diagnosis starting function information fed back by any one of the controllers, sending diagnosis request information to the controller;
step S203: diagnosing the controller when the diagnosis starting information fed back by the controller is received;
step S204: and sending a second diagnosis message to the controller after the diagnosis completion information fed back by the controller is received, so that the controller executes a diagnosis closing function according to the second diagnosis message.
In steps S201 to S204, codes corresponding to functions of different controllers are stored in the terminal device 102, and codes corresponding to functions are also stored in different controllers, and the terminal device 102 sends diagnosis request information to the plurality of controllers to diagnose the controller responding to the diagnosis request information, so as to diagnose part of the controllers, without reducing bus load in the diagnosis process, thereby improving diagnosis efficiency, and having more pertinence to problem troubleshooting, and being capable of quickly positioning problems.
In one embodiment, the step S202 includes:
step S2021: and sending the diagnosis request information to the controller in a function addressing mode or a physical information mode.
Specifically, the functional addressing is that one message corresponds to all controllers in the network, that is, all controllers in the network respond to the instruction; physical addressing is a point-to-point addressing scheme, where a message corresponds to a single controller.
As shown in fig. 5, the present application further provides a diagnostic method applied to the controller 104, the method comprising:
step S301: receiving a first diagnosis message sent by a terminal;
step S302: if the first byte value in the first diagnostic message is matched with a first preset function value, starting a diagnostic function;
step S303: responding to the request information and feeding back diagnosis starting information to the terminal when the diagnosis request information sent by the terminal is received;
step S304: and after the diagnosis is finished, if the first byte value in a second diagnosis message sent by the terminal to be received is matched with a second preset function value, the diagnosis function is closed.
In steps S301-S304, different controller functions are encoded and stored in the respective controllers 104 based on the different controllers 104 implementing the different functions. For example, when the terminal device needs to perform diagnosis of the lane keeping function for the whole vehicle, after the at least one controller with the lane keeping function receives the information containing the lane keeping function code, the at least one controller starts the diagnosis function and responds to the diagnosis request of the terminal device to realize partial diagnosis.
In one embodiment, the step S303 includes:
step S3031: and responding to the request information and feeding back diagnosis starting information to the terminal when the request information sent by the terminal in a functional addressing mode or a physical information mode is received.
In one embodiment, after step S301, the method further includes:
step S301 a: and if the first byte value in the first diagnostic message is not matched with the first preset function value, the diagnostic function is closed.
Specifically, when the first preset function value in the controller does not match the first word number value in the received first diagnostic message, it indicates that the controller does not have the function corresponding to the first byte number value in the first diagnostic message, so the diagnostic function does not need to be turned on.
It should be understood that although the various steps in the flow charts of fig. 4-5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
