Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and in the claims, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

It should be noted that, the 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 related to the present application are all authorized by the user or are fully authorized by the parties, and the collection, use, and processing of the related data is required to comply with the relevant laws and regulations and standards of the relevant countries and regions. For example, the CAN signals involved in the application are all acquired under the condition of full authorization.

Along with the development of the Internet of vehicles, the function of the vehicle is tested more conveniently, and the function of the vehicle can be tested remotely from the need of testing the real vehicle directly at a short distance to finish the test of the function of the vehicle.

As shown in fig. 1, in the related art, when testing the functions of a vehicle, a tester first needs to determine a CAN protocol used by the vehicle under test, then simulate a test CAN signal for testing the functions of the vehicle corresponding to the CAN protocol using a corresponding simulation device 11, and then send the test CAN signal to a terminal 12 corresponding to the vehicle under test using the simulation device 11. When the terminal 12 receives the test CAN signal, the test CAN signal is sent to a 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 a feedback CAN signal carrying the execution result to the terminal 12. After receiving the feedback CAN signal, the terminal 12 sends the feedback CAN signal to the simulation device 11, and a tester CAN determine whether the corresponding function in the vehicle is normal or not according to the feedback CAN signal received by the simulation device.

However, the CAN protocols used by the 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.

In addition, when the CAN protocol-oriented product is applied, products of different versions are required to be correspondingly developed because CAN protocols used by different vehicles are different, and the development cost of the products is increased.

In this regard, the embodiment of the application provides a method for testing a vehicle function, which solves the problem that in the related art, when testing the function of a vehicle using different CAN protocols, the different CAN protocols need to be compared by converting CAN signals representing the same information under different CAN protocols with the same analog signals. In order to realize the conversion from CAN signals to analog signals subsequently, the terminal CAN store the corresponding relation between the CAN signals and the analog signals under different CAN protocols in advance.

For example, under a 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 a controller to open a vehicle door is A0001; under the third CAN protocol, the CAN signal for instructing the controller to open the door is 0001A. The three CAN signals belong to CAN signals representing the same information under different CAN protocols, and all the three CAN signals are converted with MN0001. At this time, when the door opening function of the vehicle using the first to third CAN protocols is tested, it is possible to convert into the analog signal MN0001.

Referring to fig. 2, a schematic diagram of an implementation environment provided by an embodiment of the present application is shown. The implementation environment may include: a terminal 21 and a server 22. The server 22 may generate an analog signal, and may also receive the 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 also autonomously generate an analog signal. The terminal 21 CAN convert the analog signal into a CAN signal under the CAN protocol used by the vehicle under test, and CAN convert the CAN signal sent by the vehicle under test into an analog signal, and the terminal 21 CAN send the CAN signal to the controller, and CAN also receive the CAN signal fed back by the controller.

In one possible implementation, the server 22 has the function of the terminal 21 described above, and is capable of performing conversion between CAN signals and analog signals.

Alternatively, the terminal 21 may be any electronic product that can perform man-machine interaction with a user through one or more modes of a keyboard, a touch pad, a touch screen, a remote controller, a voice interaction or handwriting device, such as a PC (Personal Computer ), a mobile phone, a smart phone, a PDA (Personal DIGITAL ASSISTANT, a Personal digital assistant), a wearable device, a PPC (Pocket PC), a tablet computer, a smart car machine, a car-mounted terminal, etc. The server 22 may be a server, a server cluster comprising 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 will be appreciated by those skilled in the art that the above described terminal 21 and server 22 are by way of example only, and that other terminals or servers, now known or hereafter developed, may be adapted for use with the present application and are intended to be within the scope of the present application and are incorporated herein 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 a vehicle function according to the embodiment of the present application may include the following steps 301 to 304.

Step 301, a first analog signal for testing a target function of a vehicle is acquired.

In an exemplary embodiment, the terminal is tied to the vehicle under test and the terminal is configured in the vehicle under test such that the terminal CAN send and receive CAN signals to and from a controller in the vehicle. In some embodiments, when remotely testing the function of the vehicle, a first analog signal for testing the target function of the vehicle is generated by a device other than the terminal, and then the first analog signal is transmitted to the terminal by the device generating the first analog signal. In some embodiments, the first analog signal is generated by the cloud. At this time, acquiring a first analog signal for testing a target function of the vehicle includes: and receiving the first analog signal sent by the cloud.

The embodiment of the application is not limited as to how the cloud generates the first analog signal. The cloud terminal is provided with an input box, and when the cloud terminal detects that the content for instructing the cloud terminal to generate the first analog signal is input in the input box, the first analog signal is correspondingly generated. Alternatively, 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 generates a corresponding first analog signal after detecting the text by the cloud. For another example, the input mode corresponding to the input box is text input, the vehicle function tester inputs a text for indicating to generate the first analog signal into the input box, the cloud detects the text, determines the intention of the text expression based on the intention recognition model, and then generates the corresponding first analog signal based on the intention of the text expression. The first analog signal can be generated by directly inputting text content by the vehicle function tester through adding the intention recognition model, so that the situation that the vehicle function tester needs to memorize the content of the first analog signal is avoided, and the efficiency is improved.

In an exemplary embodiment, when the input mode corresponding to the input box is voice input, voice is first converted into corresponding text content based on a voice recognition model, and then a corresponding first analog signal is generated based on the text. In this case, the method of generating the first analog signal based on the text converted from speech is identical to the method of generating the first analog signal when the text is directly input into the input box. The voice input mode is convenient for the vehicle function tester to input the first analog signal.

In some embodiments, the content input to the input box is the same text content as the first analog signal, at which time the first analog signal is generated based on the text content, comprising: matching the text content with each analog signal stored in the analog signal library of the cloud 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 for indicating generation of the first analog signal, at which time the generation of the first analog signal based on the text content includes: determining intent of the text expression based on the intent recognition model; and acquiring corresponding virtual signals from the virtual signal library based on the intention.

In another exemplary embodiment, the input box provided by the cloud terminal corresponds to a plurality of test options, each test option corresponds to a first analog signal, and when the cloud terminal detects that any one test option is selected, the first analog signal corresponding to the any one test option is generated. Optionally, the selecting modes corresponding to the test options include: at least one of voice selection and click selection. The voice selection is to detect the voice content of the serial number corresponding to any one test option in the cloud, and determine that any one test option is selected. And the clicking selection is that the cloud detects that the display content corresponding to any one test option is clicked, and the any one test option is determined to be 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 first analog signal for testing the target function of the vehicle is correspondingly obtained. Optionally, the identity of the terminal is the VIN (Vehicle Identification Number ) of the terminal.

In some embodiments, the first analog signal is directly generated 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, that is, 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 indicating 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.

Step 302, converting the first analog signal into a first CAN signal under a CAN protocol used by the vehicle.

In an exemplary embodiment, the terminal is capable of converting CAN signals representing the same information under different CAN protocols into the same analog signal based on the correspondence of the CAN signals and the analog signal. For example, the vehicle uses a CAN protocol of a first vehicle factory, a CAN signal for opening a vehicle door is 0001, and after receiving the CAN signal, the terminal outputs an analog signal as MN0001 based on a correspondence between the CAN signal and the analog signal; or the CAN protocol used by the vehicle is a CAN protocol of a second vehicle factory, the CAN signal used for opening the vehicle door is A0001, and after the terminal receives the CAN signal, the analog signal output based on the corresponding relation between the CAN signal and the analog signal is MN0001; or the vehicle uses a CAN protocol of a third vehicle factory, the CAN signal used for opening the vehicle door is 0001A, and after the terminal receives the CAN signal, the analog signals output based on the corresponding relation between the CAN signal and the analog signals are all MN0001.

In an exemplary embodiment, the terminal is further capable of converting the analog signal into a CAN signal identifiable by the vehicle under test based on a correspondence of the CAN signal and the analog signal. Still further to the above example, when the protocol used by the vehicle to be tested is the protocol corresponding to the second vehicle factory and the door opening test is performed on the vehicle, the first analog signal received by the terminal is MN0001, and then the MN0001 is converted into the CAN signal that CAN be identified by the tested vehicle: A0001.

The embodiment of the application is not limited with respect to the coding mode of the analog signals, and CAN convert all CAN signals corresponding to the CAN protocols of each vehicle factory into only corresponding analog signals. 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 generalized 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, respectively CAN11-CAN17, and the second CAN protocol corresponds to 5 CAN signals, respectively CAN21-CAN25, wherein CAN11 is identical to CAN21 in terms of information and CAN12 is identical to CAN22 in terms of information. Thus, 10 CAN signals representing different messages CAN be generalized from the first CAN protocol and the second CAN protocol. 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 CAN signals representing different information is 900, the minimum number of bits required for encoding the analog signal is 3, i.e., 000-999, so as to ensure that the CAN signals representing different information correspond to the analog signals one by one.

For example, according to the CAN signals corresponding to the CAN protocols used by the respective factories, the number of CAN signals representing different information is summarized to be 2000, and the encoding mode of the analog signals is MN0001-MN2000.

In some embodiments, the function of the terminal to mutually convert the analog signal and the CAN signal is implemented based on an 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. Wherein, the correspondence of analog signal and CAN signal is stored in the terminal. For example, CAN signals representing information about the opening of a vehicle door are: CAN signal 0001 under CAN protocol used by the first plant; CAN signal a0001 under CAN protocol used by the second factory; CAN signal 0001A under CAN protocol used by the third driver. These three CAN signals all correspond to analog signal MN0001. The conversion application may use the correspondence to convert MN0001 to 0001, either a0001, or 0001A. And the conversion application may 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 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 is correspondingly configured, 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 mutually converting the analog signal and the CAN signal is implemented based on the conversion application, the configuring the terminal includes: the conversion application is configured to convert the analog signal to a CAN signal under a CAN protocol. At this time, after detecting the configuration result, the terminal determines that the CAN protocol corresponding to the CAN signal converted from the analog signal is 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 after receiving the analog signals, the terminal converts the received analog signals into CAN signals corresponding to the CAN protocol.

In another exemplary embodiment, after the terminal receives at least one CAN signal sent by the vehicle, the terminal matches the received at least one CAN signal with CAN signals under each CAN protocol, and determines a CAN protocol successfully matched with the received at least one CAN signal as a 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 signal under the target CAN protocol.

Step 303, a first CAN signal is sent to a controller corresponding to a target function in the vehicle, where the first CAN signal is used to instruct the controller to perform a 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 identified by a controller in the vehicle, that is, the CAN signal that CAN be identified 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 the in-vehicle air conditioner is started, after the in-vehicle air conditioner starting key is pressed, the terminal detects a signal generated by pressing the air conditioner starting key, then the signal is converted into a CAN signal which CAN be recognized by the vehicle, and the CAN signal for starting the air conditioner is sent to a corresponding controller so as to instruct the controller to perform the action of starting the air conditioner.

The CAN signal is likewise sent to the corresponding controller when testing the function of the vehicle. For example, the first CAN signal is a signal for opening a sunroof, and the terminal transmits the first CAN signal to a controller for controlling the sunroof opening to test the sunroof opening function of the vehicle.

Step 304, the receiving controller converts the second CAN signal into a second analog signal based on the second CAN signal fed back after the first CAN signal performs the corresponding action, where the second analog signal is used to determine a result of testing the target function.

In general, a controller in a vehicle generates a CAN signal for feeding back a result of the execution of the action after the execution of the action, and the controller transmits the CAN signal to a terminal bound to the vehicle through a CAN bus in the vehicle. In the embodiment of the application, after the controller corresponding to the tested vehicle function receives the first CAN signal, corresponding action is performed based on the first CAN signal, a second CAN signal is generated after the action indicated by the first CAN signal is performed, and the second CAN signal is sent to the terminal through the CAN bus in the vehicle. And after receiving the 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 the second analog signal includes: and converting the second CAN signal 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 a vehicle, in a CAN protocol of a first vehicle factory, a second CAN signal fed back by a controller after the controller successfully opens a door is 10001, and a second CAN signal fed back by the controller after the controller does not successfully open the door is 00001; in the CAN protocol of a second vehicle factory, the second CAN signal fed back by the controller after the vehicle door is successfully opened is A10001, and the second CAN signal fed back by the controller after the vehicle door is not successfully opened is A00001; in the CAN protocol of the third vehicle factory, the second CAN signal fed back by the controller after the vehicle door is successfully opened is 10001A, and the second CAN signal fed back by the controller after the vehicle door is not successfully opened is 00001A. And when the terminal receives the second CAN signals fed back after any one of the three automobile doors is successfully opened, the second analog signals output according to the corresponding relation between the analog signals and the CAN signals are all MN10001, and when the terminal receives the second CAN signals fed back after any one of the three automobile doors is not successfully opened, the second analog signals output according to the corresponding relation between the analog signals and the CAN signals are all MN00001.

In some embodiments, in order for a vehicle function tester that tests a function of a vehicle to obtain a 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, further comprising: and sending a 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.

Because one analog signal corresponds to a CAN signal representing the same information under different CAN protocols, each analog signal represents one information. Still further to the above example, the second analog signal MN10001 corresponds to a second CAN signal representing information of successful opening of the door under a different CAN protocol, and thus, the information represented by the second analog signal MN10001 is that the door is successfully opened. The second analog signal MN00001 corresponds to a second CAN signal representing information of unsuccessful opening of the door under a different CAN protocol, and thus, the information represented by the second analog signal MN00001 is unsuccessful opening of the door. Therefore, when the second analog signal received by the cloud is MN10001, the vehicle function tester can determine that the opening function of the door of the tested vehicle is normal according to the MN 10001; when the second analog signal received by the cloud is MN00001, the vehicle function tester can determine that the opening function of the door of the tested vehicle is abnormal according to the MN 00001.

In some embodiments, a target application program, for example, a vehicle setting application program, which needs to provide corresponding services according to the current state of the vehicle is installed in the terminal, and in order to facilitate the user to set the vehicle, the vehicle setting application program typically displays the current state of the vehicle through a display device of the terminal.

Such target applications, which need to provide corresponding services according to the current state of the vehicle, generally update the identification of the vehicle state according to 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 program updates the determination of the sunroof from closed to open according to the CAN signal generated after the sunroof is opened.

However, since the CAN protocols used by the vehicles produced by different factories are different, if the same target application program is to be used in the terminal corresponding to the vehicle using the different CAN protocols, multiple versions need to be developed correspondingly, so that the target application programs of different versions CAN identify the CAN signals under the different CAN protocols, and the development cost required 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 further, the identification of the vehicle state CAN be updated based on the analog signal, thereby avoiding the need of developing multiple versions adapting to different CAN protocols of the target application program.

Thus, in an exemplary embodiment, after converting the second CAN signal to the second analog signal, further comprising: the second analog signal is sent 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; the target application program provides corresponding services based on the current state of the vehicle, and integrates the function of identifying the analog signals.

In an exemplary embodiment, a test method for implementing a vehicle function by interaction between a cloud terminal and a terminal is described as an example based on the test method for a vehicle function shown in fig. 3. As shown in FIG. 4, the process of testing vehicle functionality includes, but is not limited to, the following steps 401-408.

401: The cloud generates a first analog signal;

402: the cloud sends a first analog signal to the terminal;

403: the terminal converts the first analog signal into a first CAN signal;

404: the terminal sends a first CAN signal to the controller;

405: the controller executes corresponding actions according to the first CAN signal and then generates a second CAN signal;

406: the controller feeds back a second CAN signal to the terminal;
