Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
It is noted that the terms "first," "second," and the like (if any) in the description and claims of this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
It should be noted that information (including but not limited to user equipment information, user personal information, etc.), data (including but not limited to data for analysis, stored data, presented data, etc.), and signals referred to in this application are authorized by the user or sufficiently authorized by various parties, and the collection, use, and processing of the relevant data is required to comply with relevant laws and regulations and standards in relevant countries and regions. For example, the CAN signals referred to in this application are all acquired under full authorization.
With the development of the internet of vehicles, the function of the vehicle is more conveniently tested, and the function of the vehicle can be remotely tested by directly testing the real vehicle in a short distance from the requirement.
As shown in fig. 1, in the related art, when testing the functions of a vehicle, a tester needs to determine a CAN protocol used by the vehicle to be tested, then use a corresponding simulation device 11 to simulate a test CAN signal corresponding to the CAN protocol for testing the functions of the vehicle, and then use the simulation device 11 to send the test CAN signal to a terminal 12 corresponding to the vehicle to be tested. When the terminal 12 receives the test CAN signal, the test CAN signal is sent to the corresponding controller 13 in the vehicle, and the controller 13 executes the action indicated by the test CAN signal after receiving the test CAN signal and feeds back the action to the terminal 12, wherein the feedback CAN signal carries the execution result. The terminal 12 receives the feedback CAN signal and then sends the feedback CAN signal to the simulation device 11, and the tester CAN determine whether the corresponding function in the vehicle is normal according to the feedback CAN signal received by the simulation device.
However, the different CAN protocols used by vehicles produced by different factories are different, so that when the CAN signals are simulated and whether the corresponding functions are normal or not is determined based on the CAN signals fed back by the controller, the CAN protocols used by the tested vehicles need to be compared in detail, and the efficiency of testing the functions of the vehicles produced by different factories is reduced.
Moreover, when some products developed aiming at the CAN protocol are applied, products of different versions need to be correspondingly developed because of different CAN protocols used by different vehicles, and the development cost of the products is increased.
In view of the above, the embodiment of the present application provides a method for testing a vehicle function, which converts a CAN signal representing the same information under different CAN protocols into the same analog signal, so that when testing the vehicle function, the problem that different CAN protocols need to be compared when testing the function of a vehicle using different CAN protocols in the related art is solved. In order to realize the conversion from the CAN signal to the analog signal subsequently, the terminal CAN store the corresponding relation between the CAN signal and the analog signal under different CAN protocols in advance.
For example, under the first CAN protocol, the CAN signal for instructing the controller to open the door is 0001; under a second CAN protocol, a CAN signal for indicating the controller to open the vehicle door is A0001; under the third CAN protocol, a CAN signal for indicating the controller to open the vehicle door is 0001A. The three CAN signals belong to CAN signals representing the same information under different CAN protocols, and are all converted with MN 0001. At this time, when the door opening functions of the vehicles using the first to third CAN protocols are tested, the signals CAN be converted into analog signals MN 0001.
Please refer to fig. 2, which illustrates a schematic diagram of an implementation environment provided by an embodiment of the present application. The implementation environment may include: a terminal 21 and a server 22. The server 22 may generate an analog signal, and may receive an analog signal transmitted from the terminal 21. The terminal 21 can receive the analog signal transmitted from the server 22. Alternatively, the terminal 21 may autonomously generate an analog signal. The terminal 21 CAN convert the analog signal into a CAN signal under a CAN protocol used by the vehicle under test, and CAN convert the CAN signal sent by the vehicle under test into the analog signal, and the terminal 21 CAN send the CAN signal to the controller and also CAN receive the CAN signal fed back by the controller.
In a possible implementation, the server 22 has the functions of the terminal 21 described above, and is capable of converting between a CAN signal and an analog signal.
Alternatively, the terminal 21 may be any electronic product capable of performing man-machine interaction with a user through one or more modes of a keyboard, a touch pad, a touch screen, a remote controller, voice interaction or handwriting equipment, for example, a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a PPC (Pocket PC), a tablet Computer, a smart car, a vehicle-mounted terminal, and the like. The server 22 may be a server, a server cluster composed of a plurality of servers, or a cloud computing service center. The terminal 21 establishes a communication connection with the server 22 through a wired or wireless network.
It should be understood by those skilled in the art that the terminal 21 and the server 22 are only examples, and other existing or future terminals or servers may be suitable for the present application, and are included within the scope of the present application and are herein incorporated by reference.
Based on the implementation environment shown in fig. 2, the embodiment of the present application provides a method for testing a vehicle function, which is applied to the terminal 21 as an example. As shown in fig. 3, the method for testing vehicle functions provided by the embodiment of the present application may include the following steps 301 to 304.
In an exemplary embodiment, the terminal is bound to a vehicle under test, and the terminal is configured in the vehicle under test so that the terminal CAN send and receive CAN signals fed back by the controller to the controller in the vehicle. In some embodiments, in remotely testing the functionality of the vehicle, a first analog signal for testing a target functionality of the vehicle is generated by a device other than the terminal, after which the first analog signal is sent to the terminal by the device generating the first analog signal. In some embodiments, the first analog signal is generated by a cloud. At this time, acquiring a first analog signal for testing a target function of the vehicle includes: receiving a first analog signal sent by a cloud terminal.
How the cloud generates the first analog signal is not limited in the embodiments of the present application. The cloud end is provided with an input box, and when the cloud end detects that the content used for instructing the cloud end to generate the first analog signal is input into the input box, the first analog signal is correspondingly generated. Optionally, the input mode corresponding to the input box may be at least one of text input and voice input.
For example, when the input mode corresponding to the input box is text input, the vehicle function tester directly inputs a text with the same content as the first analog signal into the input box, and the cloud end generates a corresponding first analog signal after detecting the text. For another example, the input mode corresponding to the input box is text input, the vehicle function tester inputs a text for indicating generation of the first analog signal into the input box, the cloud determines an intention of the text expression based on the intention recognition model after detecting the text, and then generates a corresponding first analog signal based on the intention of the text expression. The intention recognition model is added, so that a vehicle function tester can directly input text content to generate the first analog signal, the condition that the vehicle function tester needs to memorize the content of the first analog signal is avoided, and the efficiency is improved.
For example, when the input mode corresponding to the input box is voice input, firstly, the voice is converted into corresponding text content based on the voice recognition model, and then, a corresponding first analog signal is generated based on the text. In this case, the mode of generating the first analog signal based on the text converted by the speech is the same as the mode of generating the first analog signal when the text is directly input to the input box. The voice input mode makes the vehicle function tester more convenient when inputting the first analog signal.
In some embodiments, the content input to the input box is the same text content as the first analog signal, and generating the first analog signal based on the text content includes: matching the text content with each analog signal stored in an analog signal library at the cloud end to obtain a matching result; and acquiring an analog signal which is indicated by the matching result and is consistent with the text content.
In some embodiments, the content input to the input box is text indicating generation of the first analog signal, at which time the first analog signal is generated based on the text content, including: determining an intent of the textual expression based on an intent recognition model; a corresponding virtual signal is retrieved from a library of virtual signals based on the intent.
In another exemplary embodiment, the input box provided by the cloud end corresponds to a plurality of test options, each test option corresponds to one first analog signal, and when the cloud end detects that any one test option is selected, the cloud end generates the first analog signal corresponding to the any one test option. Optionally, the selection mode corresponding to the test option includes: at least one of a voice selection and a click selection. The voice selection is to detect the voice content of the serial number corresponding to any one test option by the cloud and determine that the any one test option is selected. And clicking selection is to detect that the display content corresponding to any test option is clicked by the cloud, and determine that any test option is selected.
After the cloud generates the first analog signal, the first analog signal is sent to the terminal based on the identification of the terminal, and after the terminal receives the first analog signal sent by the cloud, the acquisition of the first analog signal for testing the target function of the vehicle is correspondingly completed. Optionally, the identifier of the terminal is a VIN (Vehicle Identification Number) of the terminal.
In some embodiments, the first analog signal is generated directly by the terminal, and the manner of generating the first analog signal is consistent with the manner of generating the first analog signal by the cloud, i.e., the terminal is provided with an input box. At this time, acquiring a first analog signal for testing a target function of the vehicle includes: content instructing generation of the first analog signal is acquired based on the input box, and a corresponding first analog signal is generated based on the content.
In an exemplary embodiment, the terminal CAN convert CAN signals representing the same information under different CAN protocols into the same analog signal based on the correspondence between the CAN signals and the analog signal. For example, the vehicle uses a CAN protocol of a first factory, a CAN signal for opening a door is 0001, and after receiving the CAN signal, the terminal outputs an analog signal of MN0001 based on a correspondence between the CAN signal and the analog signal; or the vehicle uses a CAN protocol of a second factory, the CAN signal for opening the door is A0001, and the analog signal output based on the corresponding relation between the CAN signal and the analog signal is MN0001 after the terminal receives the CAN signal; or the vehicle uses a CAN protocol of a third vehicle factory, the CAN signal for opening the door is 0001A, and after the terminal receives the CAN signal, the analog signals output based on the correspondence between the CAN signal and the analog signals are all MN 0001.
In an exemplary embodiment, the terminal is further capable of converting the analog signal into a CAN signal recognizable by the vehicle to be tested based on a correspondence relationship between the CAN signal and the analog signal. Still by way of example, the protocol used by the vehicle to be tested is a protocol corresponding to the second factory, when the vehicle is subjected to the door opening test, the first analog signal received by the terminal is MN0001, and then MN0001 is converted into a CAN signal that CAN be recognized by the vehicle to be tested: A0001.
the embodiment of the present application is not limited to the encoding method of the analog signal, and all the CAN signals corresponding to the CAN protocols of each vehicle factory CAN be converted into the unique corresponding analog signal. For example, since the number of CAN signals corresponding to each CAN protocol is determined and the information represented by each CAN signal is determined, the number of CAN signals representing different information CAN be summarized according to the CAN signals corresponding to the CAN protocols used by the respective factories. For example, the first CAN protocol corresponds to 7 CAN signals, CAN11-CAN17 respectively, and the second CAN protocol corresponds to 5 CAN signals, CAN21-CAN25 respectively, wherein the information represented by CAN11 and CAN21 is the same, and the information represented by CAN12 and CAN22 is the same. Thus, 10 CAN signals representing different information CAN be summarized according to the first and second CAN protocols. After the number of CAN signals representing different information is obtained, the minimum number of bits required for encoding of the analog signal CAN be determined. For example, if the number of the CAN signals representing different information is 900, the minimum number of bits required for encoding the analog signal is 3, i.e., 000-999, thereby ensuring that the CAN signals representing different information correspond to the analog signal one-to-one.
For example, if the number of the CAN signals representing different information is 2000 according to the CAN signals corresponding to the CAN protocol used by each car manufacturer, the encoding mode of the analog signal is MN0001-MN 2000.
In some embodiments, the terminal is capable of performing a function of converting the analog signal and the CAN signal to each other based on the application conversion program. The conversion application program CAN complete the mutual conversion between the analog signal and the CAN signal based on the corresponding relation between the CAN signal and the analog signal. And the corresponding relation between the analog signal and the CAN signal is stored in the terminal. For example, CAN signals representing information to open a vehicle door include: CAN signal 0001 under CAN protocol used by the first vehicle factory; a CAN signal a0001 under a CAN protocol used by the second plant; CAN signal 0001A under the CAN protocol used by the third vehicle factory. The three CAN signals all correspond to the analog signal MN 0001. The conversion application can convert MN0001 into 0001, or a0001, or 0001A using the correspondence. And the conversion application can also convert any one of 0001, a0001, 0001A into MN0001 using the correspondence.
In some embodiments, it is desirable to determine which CAN protocol is used by the vehicle before converting the first analog signal to a first CAN signal under the CAN protocol used by the vehicle. The embodiments of the present application are not limited with respect to how the CAN protocol used by the vehicle is determined.
Optionally, after the CAN protocol used by the vehicle is manually determined, the terminal may be configured accordingly, and after the terminal detects the configuration result, the CAN protocol used by the vehicle is determined based on the configuration result. In an exemplary embodiment, when the function of converting the analog signal and the CAN signal to each other is implemented based on a conversion application, the terminal is configured accordingly, including: the conversion application is configured to convert the analog signal to a CAN signal under a CAN protocol. At this time, after the terminal detects the configuration result, the CAN protocol corresponding to the CAN signal converted from the analog signal is determined to be the CAN protocol used by the vehicle. In this case, before converting the first analog signal into the first CAN signal under the CAN protocol used by the vehicle, the method further includes: and determining the CAN protocol used by the vehicle according to the configuration result.
It should be noted that, a corresponding CAN protocol is selected in the conversion application program, and the terminal CAN determine the CAN protocol used by the vehicle after detecting that the CAN protocol is selected. And then, after the terminal receives the analog signal, the received analog signal is converted into a CAN signal corresponding to the CAN protocol.
In another exemplary embodiment, after receiving at least one CAN signal sent by the vehicle, the terminal matches the received at least one CAN signal with CAN signals under various CAN protocols, and determines the CAN protocol successfully matched with the received at least one CAN signal as the CAN protocol used by the vehicle. At this time, before converting the first analog signal into the first CAN signal under the CAN protocol used by the vehicle, the method further includes: acquiring at least one CAN signal generated by a vehicle; matching at least one CAN signal generated by the vehicle with CAN signals under each CAN protocol to obtain a matching result; and determining the target CAN protocol as the CAN protocol used by the vehicle in response to the matching result indicating that at least one CAN signal is contained in the CAN signals under the target CAN protocol.
And 303, sending a first CAN signal to a controller corresponding to the target function in the vehicle, wherein the first CAN signal is used for indicating the controller to perform corresponding action.
In some embodiments, when the vehicle is controlled, the corresponding analog signal needs to be converted into a CAN signal that CAN be recognized by a controller in the vehicle, that is, the CAN signal that CAN be recognized by the vehicle, and then the CAN signal is sent to the controller to instruct the controller to perform a corresponding action. For example, when an air conditioner in a vehicle is started, after an air conditioner start key in the vehicle is pressed, a terminal detects a signal generated by pressing the air conditioner start key, converts the signal into a CAN signal which CAN be recognized by the vehicle, and sends the CAN signal for starting the air conditioner to a corresponding controller so as to instruct the controller to start the air conditioner.
In the case of testing the function of the vehicle, CAN signals are likewise sent to the respective controllers. For example, the first CAN signal is a signal for opening a sunroof, and the terminal sends the first CAN signal to a controller for controlling opening of the sunroof, so as to test a sunroof opening function of the vehicle.
And 304, receiving a second CAN signal fed back after the controller executes a corresponding action based on the first CAN signal, and converting the second CAN signal into a second analog signal, wherein the second analog signal is used for determining a result of testing the target function.
Generally, a controller in a vehicle generates a CAN signal for feeding back an action execution result after executing the action, and the controller transmits the CAN signal to a terminal bound with the vehicle through a CAN bus in the vehicle. In the embodiment of the application, after receiving the first CAN signal, the controller corresponding to the tested vehicle function performs a corresponding action based on the first CAN signal, and generates a second CAN signal after executing the action indicated by the first CAN signal, and sends the second CAN signal to the terminal through the CAN bus in the vehicle. And after receiving a second CAN signal fed back by the controller, the terminal converts the second CAN signal into a second analog signal. Illustratively, converting the second CAN signal to a second analog signal includes: the second CAN signal is converted into a second analog signal based on a correspondence between the analog signal and the CAN signal, wherein the correspondence between the analog signal and the CAN signal is stored in the terminal.
For example, the target function is a door opening function of the vehicle, in a CAN protocol of a first vehicle factory, a second CAN signal fed back by the controller after the controller successfully opens the door is 10001, and a second CAN signal fed back by the controller after the controller fails to successfully open the door is 00001; in a CAN protocol of a second vehicle factory, a second CAN signal fed back by the controller after the controller successfully opens the vehicle door is A10001, and a second CAN signal fed back by the controller after the controller fails to open the vehicle door is A00001; in the CAN protocol of the third car factory, the second CAN signal fed back by the controller after the controller successfully opens the car door is 10001A, and the second CAN signal fed back by the controller after the controller fails to successfully open the car door is 00001A. After the terminal receives any one of the three second CAN signals fed back after the door of the vehicle is opened successfully, the second analog signals output according to the corresponding relation between the analog signals and the CAN signals are all MN10001, and after the terminal receives any one of the three second CAN signals fed back after the door of the vehicle is not opened successfully, the second analog signals output according to the corresponding relation between the analog signals and the CAN signals are all MN 00001.
In some embodiments, in order for a vehicle function tester testing the functions of the vehicle to obtain the test result, the terminal needs to send a second analog signal to the cloud. Thus, after converting the second CAN signal into the second analog signal, the method further includes: and sending the second analog signal to the cloud end, wherein the second analog signal is used for determining a result of testing the target function by the cloud end.
Since one analog signal corresponds to CAN signals representing the same information under different CAN protocols, each analog signal represents one information. Still referring to the above example, the second analog signal MN10001 corresponds to a second CAN signal under a different CAN protocol indicating that the door is successfully opened, and thus the second analog signal MN10001 indicates that the door is successfully opened. The second analog signal MN00001 corresponds to a second CAN signal representing information that the door was not successfully opened under a different CAN protocol, and thus the information represented by the second analog signal MN00001 represents that the door was not successfully opened. Therefore, when the second analog signal received by the cloud is MN10001, the vehicle function tester can determine that the door opening function of the vehicle to be tested is normal according to MN 10001; when the second analog signal received by the cloud end is MN00001, the vehicle function tester can determine that the opening function of the vehicle door of the tested vehicle is abnormal according to MN 00001.
In some embodiments, a target application that needs to provide a corresponding service according to the current state of the vehicle is installed in the terminal, for example, a vehicle setting application, and in order to facilitate a user to set the vehicle, the vehicle setting application will generally display the current state of the vehicle through a display device of the terminal.
Such target applications that need to provide corresponding services according to the current state of the vehicle usually update the vehicle state determination by the CAN signal fed back to the terminal after the vehicle state changes. For example, after the door of the vehicle is opened, the target application updates the identification of the sunroof from closed to open according to the CAN signal generated after the sunroof is opened.
However, because the CAN protocols used by vehicles produced by different vehicle factories are different, if the same target application program is used in terminals corresponding to vehicles using different CAN protocols, multiple versions need to be developed correspondingly, so that the target application programs of different versions CAN recognize CAN signals under different CAN protocols, and the development cost for developing the target application programs of multiple versions is high. For the problem, the function of identifying the analog signal CAN be directly integrated in the target application program, so that the target application program CAN identify the analog signal, and then the identification of the vehicle state CAN be updated based on the analog signal, thereby avoiding the target application program from needing to develop various versions which are suitable for different CAN protocols.
Thus, in an exemplary embodiment, after converting the second CAN signal to the second analog signal, the method further includes: sending the second analog signal to the target application program so that the target application program updates the state of the vehicle based on the test result corresponding to the second analog signal; wherein the target application provides a corresponding service based on the current state of the vehicle, and the target application is integrated with a function of recognizing the analog signal.
In an exemplary embodiment, based on the vehicle function testing method shown in fig. 3, a testing method in which a cloud terminal and a terminal interact to realize a vehicle function is taken as an example for description.

406: the controller feeds back a second CAN signal to the terminal;
407: the terminal converts the second CAN signal into a second analog signal;
408: the terminal sends the second analog signal to the cloud end, and the terminal sends the second analog signal to the target application program.
In the embodiment of the application, the CAN signals which CAN be identified by the vehicle are converted with the analog signals, so that the testing of the vehicle functions CAN be completed only according to the analog signals when the vehicle using different CAN protocols is tested, and the testing result is determined without paying attention to the CAN signals under the different CAN protocols, and the efficiency of testing the vehicle functions is improved.
In another exemplary embodiment, the conversion between the analog signal and the CAN signal is completed in a cloud, the cloud sends the converted CAN signal to a terminal bound with a vehicle with a tested function, and the cloud receives the CAN signal sent by the terminal and CAN convert the received CAN signal into the analog signal. When conversion between analog signal and the CAN signal is accomplished in the high in the clouds, the terminal that CAN not bind with the vehicle possesses the function of conversion between analog signal and the CAN signal, only need the high in the clouds possess with the function of conversion between analog signal and the CAN signal CAN, further raise the efficiency.
