[0054] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.
[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.
[0056] As described in the background section, before adopting communication management methods such as CANFD, signal simulation tests need to be performed on each electronic control unit in the vehicle. However, existing signal simulation test solutions all configure and send test signals through Canoe or third-party IDE tools, which have high learning costs, low ease of use, and low signal testing efficiency.
[0057] To address the aforementioned problems in the prior art, embodiments of this application provide a signal testing method, apparatus, device, storage medium, and computer program product. It should be noted that the embodiments provided in this application are not intended to limit the scope of this disclosure.
[0058] The signal testing method provided in the embodiments of this application will be described below.
[0059] Figure 1 A schematic flowchart of a signal testing method according to an embodiment of this application is shown. This signal testing method is applied to an electronic device, which may include a server or a user terminal, etc. During signal testing, the electronic device can connect to the vehicle under test. Figure 1 As shown, the signal testing method includes the following steps:
[0060] S110, Receive a first input, the first input is used to determine a first initial signal;
[0061] S120, based on the vehicle's DBC file, converts the first initial signal into a first standard signal;
[0062] S130, based on the message encapsulation rules corresponding to the target signal device in the vehicle, encapsulate the first standard signal into a target message;
[0063] S140, the target message is sent to the target signal device to perform signal testing on the target signal device.
[0064] The signal testing method of this application embodiment determines a first initial signal by receiving a first input, converts the first initial signal to a standard signal format according to the vehicle's DBC file, encapsulates the message according to the message encapsulation rules specified by the target signal device to be tested, and finally sends the generated message to the target signal device, thereby realizing signal transmission in the signal testing of the target signal device. The signal testing method provided by this application embodiment can perform a series of compatible conversions on the first initial signal, thus eliminating the need to switch between different external tools for testing different signal devices. This reduces the operational learning cost and enhances usability during signal testing, while also significantly improving the efficiency of signal simulation testing.
[0065] In S110, in a specific implementation, a first input is received, which is used to determine a first initial signal.
[0066] In this embodiment, a relevant display interface may be configured on the front end of the electronic device so that the user can perform operations such as clicking, touching, or inputting characters for the first input. Please refer to [link to relevant documentation]. Figure 2 , Figure 2This is a schematic diagram of the front-end display interface provided in one embodiment of this application.
[0067] like Figure 2 As shown, users can input the specific signal text of the first initial signal under the corresponding signal type through click, touch and other operations on the front-end display interface. This allows users to customize the input of the first input by operating the front-end display interface. The first input will specifically include the specific signal text of the first initial signal.
[0068] Alternatively, the front-end display interface may also provide a function for selecting historical signal configurations. Based on this, users can also select the desired first initial signal from historical signals by clicking on the historical signal configuration, thereby more conveniently realizing the above-mentioned first input. This application does not impose any specific restrictions on this.
[0069] In S120, in a specific implementation, the first initial signal can be converted into a first standard signal based on the vehicle's DBC file and according to the signal conversion rules specified in the vehicle's DBC file.
[0070] It should be noted that the DBC files differ for different vehicles in this application. DBC (Database Can) represents the CAN database file, and communication in the CAN bus network within a vehicle often relies on the description in this DBC file. The CAN communication information is specifically defined in the DBC file, enabling error-free collaborative and synchronous development of the node controllers throughout the CAN bus network.
[0071] In some possible implementations, in order to more reasonably achieve the signal format conversion of the aforementioned first initial signal, the vehicle-based DBC file converts the first initial signal into a first standard signal, which may specifically include:
[0072] Determine the signal type of the first initial signal;
[0073] Based on the conversion rules and DBC file corresponding to the signal type of the first initial signal, the first initial signal is converted into a first standard signal.
[0074] In this embodiment, considering the user's perspective, in order to facilitate the user's initial signal input, the first initial signal may often have different signal body formats, that is, different signal types, such as JSON text format, simple code format, or hexadecimal string format, etc.
[0075] Therefore, in order to achieve a more reasonable and efficient conversion of the signal format of the aforementioned first initial signal, different conversion rules can be set for initial signals of different signal types. Thus, after determining the first initial signal, the signal type of the first initial signal can be determined first, and then, based on the conversion rules corresponding to the signal type of the first initial signal and in conjunction with the vehicle's DBC file, the first initial signal can be converted into a first standard signal.
[0076] In some possible implementations, to further achieve signal format conversion of the first initial signal, if the signal type of the first initial signal supports combined signals, the first initial signal is converted into a first standard signal based on the conversion rules and DBC file corresponding to the signal type of the first initial signal. This may include:
[0077] Detect whether the first initial signal is a combined signal;
[0078] In the case where the first initial signal is a combined signal, the first initial signal is converted and split into multiple first standard signals based on the conversion rules and DBC file corresponding to the signal type of the first initial signal.
[0079] In this embodiment, if the first initial signal is determined to be a combined signal, it is converted and split during the subsequent conversion process of the first initial signal, thereby converting and decomposing the combined signal into multiple single standard signals.
[0080] In S130, in specific implementation, the first standard signal is encapsulated into a target message based on the message encapsulation rules corresponding to the target signal device in the vehicle.
[0081] It should be noted that in this embodiment, the vehicle includes multiple electronic control units (ECUs), and the target signal device can be any electronic control unit (ECU) in the vehicle that needs to be tested for signals. This application does not impose any specific restrictions on this.
[0082] In practice, message encapsulation rules for each electronic control unit (ECU) can be predefined according to their communication requirements and message specifications. Then, after obtaining the first standard signal, the first standard signal is encapsulated according to the message encapsulation rules corresponding to the target signal device to generate the target message.
[0083] It should be noted that, considering the diversity of existing message encapsulation methods and the complexity of the actual message encapsulation process, this application will not elaborate on how to implement message encapsulation in detail.
[0084] In S140, in specific implementation, the target message is sent to the target signal device to perform signal testing on the target signal device.
[0085] In some possible implementations, more specifically, the above-described sending of the target message to the target signal device may include: invoking a communication interface that matches the target signal device to send the target message to the target signal device.
[0086] In this application, the aforementioned communication interface can be a bus interface implemented based on a CAN / CANFD bus network. Specifically, after generating the target message, the target message is efficiently and accurately transmitted to the target signal device in the vehicle by calling the communication interface that matches the target signal device.
[0087] In some possible implementations, considering the repeatability of the test signal during signal testing, and in order to improve the user's convenient input of the initial signal during signal testing and further enhance the efficiency of signal testing, after receiving the first input, the signal testing method may further include:
[0088] Store the first initial signal into the historical signal set;
[0089] After sending the first message to the target signal device, the signal testing method may further include:
[0090] In response to the second input, the first initial signal from the historical signal set is displayed;
[0091] Invoke the first initial signal.
[0092] In practice, after receiving the first input and determining the first initial signal based on the first input, the first initial signal is saved to the historical signal set. Thus, when the user needs to perform a signal test again, by clicking or touching the historical signal set as a second input, the historical signal set, which includes the previously stored first initial signal, is displayed on the front of the electronic device.
[0093] Thus, when the first initial signal of the historical signal set is displayed on the front-end display interface of the device, the user can quickly select and call the first initial signal by clicking, double-clicking or other operations, without having to edit and input the specific signal content of the first initial signal again, which effectively improves the efficiency of signal testing and the ease of operation.
[0094] In some possible implementations, to facilitate recording of the signal testing process for subsequent statistical analysis of signal test results, the signal testing method may further include the following after sending the target message to the target signal device:
[0095] The feedback information sent by the target signal device corresponds to the first initial signal;
[0096] Based on the feedback information and the first initial signal, the first log record is generated.
[0097] In practice, after the target message is sent to the target signal device in the vehicle, the vehicle host and the target signal device in the vehicle will perform corresponding signal processing based on the received target message. After the message is received and the signal is processed according to the message, the target signal device in the vehicle will output corresponding feedback information.
[0098] In this way, after receiving the feedback information corresponding to the first initial signal sent by the target signal device of the vehicle, the feedback information is saved, and the feedback information and the aforementioned first initial signal are combined to generate a log record, namely the first log record, so as to be traced and analyzed in subsequent log records generated according to different signal test stages.
[0099] In some possible implementations, the inventors of this application, considering ease of use for users, have customized the initial signal under the first signal type and set corresponding conversion rules according to the customized first signal type. Specifically, the initial signal under the aforementioned first signal type may include a message identifier, a signal name, and a signal value;
[0100] When the signal type of the first initial signal is a first signal type, converting the first initial signal into a first standard signal based on the conversion rules and DBC file corresponding to the signal type of the first initial signal may include:
[0101] Check if the message identifier and signal name of the first initial signal exist in the DBC file;
[0102] If the message identifier and signal name of the first initial signal exist in the DBC file, the signal value in the first initial signal is converted into a hexadecimal string based on the DBC file to obtain the first standard signal.
[0103] For specific implementation details, please refer to [link / reference]. Figure 3 , Figure 3 This is one of the schematic diagrams illustrating the signal conversion process of the first initial signal provided in an embodiment of this application. For example... Figure 3 As shown, the first signal type is Form Signal. The initial signal under Form Signal is defined as a simple single-line single-signal body format, following: Msg ID[Msg Name].Signal Name = Signal Value#Notes.
[0104] In this field, either Msg ID or Msg Name can be used as the message identifier. Msg ID is the message ID, and Msg Name is the message name. Signal Name is the individual signal name. Signal Value is the signal value, which can be a single hexadecimal character or a value copied from the signal value description column in the vehicle's DBC file. Notes are annotations and are optional.
[0105] For example, when the first initial signal is of the Form Signal type, the first initial signal can specifically be: 0x1C1.WCML_WCMSetSt = 0x1#Left charging display. When specifically performing signal conversion for this first initial signal, such as... Figure 3 As shown, the Msg ID in the first initial signal is first matched according to the vehicle's DBC file. If there is no message identifier matching the Msg ID in the vehicle's DBC file, the conversion fails and the conversion process ends.
[0106] If a message identifier matching the Msg ID exists in the vehicle's DCB file, the matching of the Signal Name in the first initial signal continues according to the vehicle's DBC file. If no matching signal name exists in the vehicle's DCB file, the matching fails and the conversion process ends. If a matching signal name exists in the vehicle's DCB file, the Signal Value in the first initial signal is converted into a fixed-length hexadecimal string according to the relevant rules in the vehicle's DBC file, thus completing the conversion from the first initial signal to the first standard signal.
[0107] In some possible implementations, this application also provides an initial signal of a second signal type and a signal format conversion means under the second signal type. Specifically, the initial signal under the second signal type adopts a JSON text format, and the initial signal under the second signal type may include a message identifier and N signal names, where N is a positive integer. The second signal type supports combined signals.
[0108] When the signal type of the first initial signal is the second signal type, converting the first initial signal into a first standard signal based on the conversion rules and DBC file corresponding to the signal type of the first initial signal may include:
[0109] Detect whether the message identifier of the first initial signal exists in the DBC file;
[0110] If the message identifier of the first initial signal exists in the DBC file, the values corresponding to the N signal names in the first initial signal are converted into hexadecimal strings based on the DBC file to obtain the first standard signals corresponding to the N signal names respectively.
[0111] For specific implementation details, please refer to [link / reference]. Figure 4 , Figure 4 This is a second schematic diagram of the signal conversion process of the first initial signal provided in an embodiment of this application. The second signal type is a Body Signal. Figure 4 In this context, either the `msg_id` or `msg_name` field can be used as a message identifier. `Signal Name` is the signal name; multiple signal names are allowed in the initial signal of this second signal type. `Value` is the value corresponding to the signal name, which can be a single hexadecimal character or a value copied from the signal value description column of the vehicle's DBC file.
[0112] When specifically performing signal conversion of the first initial signal of this second signal type, such as Figure 3 As shown, the msg_id or msg_name field in the first initial signal is first matched against the vehicle's DBC file. If there is no message identifier in the vehicle's DBC file that matches the msg_id or msg_name field, the conversion fails and the conversion process ends.
[0113] If the vehicle's DCB file contains a message identifier that matches the msg_id or msg_name field in the first initial signal, then according to the relevant rules in the vehicle's DBC file, the Value corresponding to each SignalName in the first initial signal is converted into a fixed-length hexadecimal string, ultimately resulting in multiple first standard signals corresponding to different signal names in the first initial signal.
[0114] In some other possible implementations, the inventors of this application have also defined an initial signal for a third signal type, DataSignal, which can be found in [reference needed]. Figure 5 , Figure 5 This is the third schematic diagram of the signal conversion process of the first initial signal provided in one embodiment of this application. Figure 5 As shown, when the first initial signal is of the third signal type, the initial signal under this third signal type is the original signal body, which includes the message identifier MsgID and a hexadecimal string. It directly selects the signal from the DBC file published by the vehicle and sends the signal by giving the original hexadecimal bit characters.
[0115] To facilitate understanding of the signal testing method provided in the above embodiments, the following describes the method using a complete overall embodiment. Figure 6 This is a schematic diagram of the overall process of a signal testing method provided in an embodiment of this application.
[0116] like Figure 6 As shown, in the overall embodiment, signal testing is achieved through interaction between a PC (personal computer) and the vehicle. The user can perform relevant input operations on the CAN panel displayed on the front-end interface. The user can directly customize the first initial signal on the front-end CAN panel of the PC and store this first initial signal in the corresponding memory using data storage services. Alternatively, the user can retrieve historically configured signals from the data storage service and select a historical signal as the first initial signal; this embodiment does not impose specific limitations.
[0117] Based on the previous examples, the initial signal supports three signal types: Form Signal, BodySignal, and Data Signal. After obtaining the first initial signal based on the front-end command, the background program service on the PC can perform corresponding signal compatibility conversion processing on the first initial signal.
[0118] Specifically, the signal type of the first initial signal is first determined, and the first initial signal is converted into a first standard signal according to the conversion rules corresponding to the signal type of the first initial signal and the vehicle's DBC file.
[0119] It should be noted that, if the signal type of the first initial signal is determined to be the second signal type, Body Signal, since the second signal type supports combined messages, it is possible to further determine whether the first initial signal is a combined signal (combined message). If it is not a combined message, it is processed and converted as a normal single message to obtain the first standard signal. If it is a combined message, it is converted into multiple single signals to obtain multiple first standard signals.
[0120] After obtaining the first standard signal, it is input to the signal compatibility processing module on the PC. In this module, the input first standard signal is encapsulated according to the message encapsulation rules that match the signal device under test to obtain the target message.
[0121] After generating the target message, the target message is efficiently and accurately transmitted to the signaling equipment in the vehicle by calling the communication interface service that matches the target signaling equipment.
[0122] After receiving the target message, the signal equipment and the vehicle host in the vehicle will perform signal coordination and response based on the target message. The signal equipment in the vehicle will then send the corresponding feedback information (response result) to the PC and store it in the corresponding memory based on the data storage service so that the signal test results can be analyzed later.
[0123] In this overall embodiment, compared to the existing signal simulation test schemes that configure and send test signals through Canoe or third-party IDE tools, this embodiment can determine the initial signal through custom configuration or by calling historical signal configurations. By performing signal format conversion and message encapsulation on the initial signal, the initial signal is automatically converted into a message that can be received by various signal devices in the vehicle, eliminating the need for complex operations and switching of the IDEs for each signal device in the vehicle.
[0124] Furthermore, in this embodiment, the initial signal can support multiple configurations, and conversion rules matching different signal types can be set to maximize the user experience and convenience during signal testing, greatly improving signal testing efficiency, simplifying the operation difficulty for testers, and reducing the learning cost of operation during signal testing.
[0125] Based on the signal testing method provided in the above embodiments, this application also provides a signal testing device corresponding to the above signal testing method, which will be described below. Figure 7 A detailed introduction to the signal testing device is provided.
[0126] Figure 7 A schematic diagram of the structure of a signal testing device provided in an embodiment of this application is shown. Figure 7 The signal testing apparatus 700 shown includes:
[0127] The first receiving module 710 is used to receive a first input, which is used to determine a first initial signal;
[0128] The first conversion module 720 is used to convert the first initial signal into a first standard signal based on the vehicle's DBC file;
[0129] The first encapsulation module 730 is used to encapsulate the first standard signal into a target message based on the message encapsulation rules corresponding to the target signal device in the vehicle;
[0130] The first sending module 740 is used to send the target message to the target signal device to perform signal testing on the target signal device.
[0131] The signal testing device of this application embodiment, by setting corresponding functional modules, can receive a first input to determine a first initial signal, convert the first initial signal to a standard signal format according to the vehicle's DBC file, encapsulate the message according to the message encapsulation rules specified by the target signal device to be tested, and finally send the generated message to the target signal device, thereby realizing signal transmission in the signal testing of the target signal device. The signal testing device provided in this application embodiment can perform a series of compatible conversion processes on the first initial signal, thus eliminating the need to switch between different external tools for testing different signal devices. This reduces the operational learning cost in the signal testing process, enhances ease of use, and significantly improves the efficiency of signal simulation testing.
[0132] In some possible implementations, considering the repeatability of the test signal during signal testing, and in order to improve the user's convenient input of the initial signal during signal testing and further enhance the efficiency of signal testing, the signal testing device may further include, after receiving the first input:
[0133] The first storage module can be used to store the first initial signal into a historical signal set;

[0137] In some possible implementations, to facilitate recording of the signal testing process for subsequent statistical analysis of signal test results, the signal testing device may further include:
