When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Also, it should be noted that, for simplicity of description, the method embodiments provided by the present disclosure are all described as a series of acts, but one skilled in the art should appreciate that the present disclosure is not limited by the order of acts described. Further, those skilled in the art will also appreciate that the embodiments described in the specification are all preferred embodiments and that the acts referred to are not necessarily required by the present disclosure.
Fig. 1 is a flow chart illustrating a method of transmitting test messages according to an exemplary embodiment, and referring to fig. 1, the method includes the steps of:
in step S11, a preset signal value rule is invoked for the acquired test content, so as to generate a test value of the test content and a text description corresponding to the test value.
Specifically, the test content corresponds to the alarm content, and the preconfigured signal value rule may be to establish a plurality of signal values corresponding to the CAN message for the CAN message of each test content. It is readily understood that the range of signal values preconfigured for different test contents is different. Illustratively, the pre-configured signal range for the test content "coolant temperature" may be 90-100; whereas the pre-configured signal value range for the test content "coolant liquid level" may be 0-20.
In the implementation, keywords of test contents input by a user can be obtained by configuring a front-end page, the keywords are further used as the test contents, a pre-configured signal value rule is called, and a test value corresponding to the test contents and a text description corresponding to the test value are generated. For example, the keyword "coolant temperature" input by the user on the front-end page is acquired, the corresponding test value "96" and the text description of the corresponding test value are generated as "coolant temperature", or the corresponding test value "20" and the text description of the corresponding test value "coolant liquid level" are generated.
In step S12, a test message address is determined according to the test value and the corresponding text description.
In one embodiment, referring to fig. 2, in step S12, the determining the address of the test message according to the test value and the corresponding text description includes the following steps.
In step S121, the test value is combined with the corresponding text description to obtain a test key value pair.
And determining mathematical symbols of the key value pairs according to the magnitude relation between the normal value and the test value, and respectively filling text description and the test value at two ends of the mathematical symbols to construct the key value pairs. According to the description of the embodiment, the temperature of the cooling liquid is described, according to the magnitude relation between the normal value of the cooling liquid temperature and the test value, the test value is determined to be 96 ℃ higher than the normal value of the cooling liquid temperature, the mathematical sign of the key value pair is determined to be 'greater than', and the two sides of the key value pair which are greater than are respectively filled with the cooling liquid temperature and the cooling liquid temperature 96, so that the key value pair is constructed to be greater than 96.
For another example, for the text description as the liquid level of the cooling liquid, according to the magnitude relation between the normal value of the liquid level of the cooling liquid and the test value, determining that the test value 20 is lower than the normal value of the liquid level, determining that the mathematical sign of the key value pair is ' less than ', filling ' liquid level of the cooling liquid ' and ' 20 ' at two sides of ' less than ', respectively, and constructing the key value pair that ' liquid level of the cooling liquid ' is less than 20 '.
On the basis of the above embodiment, the test value is plural; in step S121, the step of combining the test value with the corresponding text description to obtain a test key value pair includes the following steps.
According to the data structure of the preset key value pair, each text description is used as a keyword, and the keyword is filled in the keyword position of the data structure, wherein the keyword position is a space for storing keywords in the data structure.
Determining the type of the data structure calling the preset key value pair according to the magnitude relation between the normal value and the test value, for example, in the case that the test value of the cooling liquid temperature is 96, determining that the type of the data structure calling the preset key value pair is 'key 1 > value 1' because the test value 96 exceeds the normal value of the cooling liquid temperature; for another example, in the case where the test value of the coolant temperature is 75, since the test value 75 is a normal value of the coolant temperature, it is determined that the type of the data structure calling the preset key value pair is "ken2=valude2"; for another example, in the case where the test value of the coolant liquid level is 20, since the test value 20 is lower than the normal value of the coolant liquid level, it is determined that the type of the data structure calling the preset key value pair is "key3 < value 3".
Further, a data structure of the preset key value pair of the type is called, a calling function is written in advance, keywords are searched in the text description, and the text description is filled into the keyword position of the data structure under the condition that the searched keywords are matched with preset target keywords. For example, the keyword "coolant temperature" is filled into the keyword position "key1" of the data structure.
And taking the test value corresponding to each text description as a data value, filling the data bit corresponding to the keyword, and obtaining a plurality of key value pairs, wherein the data bit is a space for storing the data value in the data structure.
The test value 96 is filled into the data bit "value 1" corresponding to the keyword "coolant temperature" by calling a function, and a measured key value pair is obtained. And similarly, filling other test values into data bits corresponding to the keywords to obtain a plurality of key value pairs.
In step S122, based on the pre-configured message matrix, the test message address of the test key value pair is matched from the message matrix.
The pre-configured message matrix establishes a corresponding relation between the text description represented by the key value pair and the test message address, and a corresponding relation between the test value and the test message address. The unique test message address of the key value pair can be determined through the corresponding relation of every two.
By adopting the technical scheme, based on the pre-configured message matrix, the corresponding test message address is matched with the key value pair, so that the message matrix can be expanded, the expandability and convenience of testing are improved, and the testing cost is reduced.
In step S13, based on the pre-configured frame format, a test message under the frame format is generated according to the test message address, and the test message is sent to the CAN bus.
Alternatively, the frame format may be a standard frame and an extended frame.
Specifically, the data position of the test message address in the test message is determined according to the text description in the test content. And filling the test message address into the data position to generate the test message under the frame format.
And sending the test message to the CAN bus by driving the CANoe and calling the corresponding gateway. So that a controller connected to the CAN bus, for example, a car networking controller (T-Box), an in-car central control system, CAN acquire test messages from the CAN bus.
According to the technical scheme, the text description and the test value are generated according to the preset signal value rule aiming at the test content, so that the signal value is prevented from being filled in aiming at each text description, and the test convenience is improved. The test cost is reduced.
For the same alarm content, different signal values usually exist, so that in the process of generating the test message, a plurality of different test values can be generated to simulate different signal values of the vehicle for the same alarm content.
On the basis of the above embodiment, the plurality of test signal values and the plurality of test values are generated according to the test content and the preset number by adopting a random algorithm, or the given value is used as a starting value, and the test values are obtained by performing operation with a preset step length in each operation until the number of the test values reaches the preset number.
Specifically, the preset step length is used for representing the difference value between the plurality of test values, for example, the preset step length is used for taking any value as an initial value, and the value corresponding to the step length is subtracted or added circularly to obtain a plurality of test values which change continuously until the number of the test values reaches the preset number.
In one embodiment, the test value is rejected if the test value is not within a preset test threshold range. Taking the temperature of the cooling liquid as an example for explanation, the temperature of the cooling liquid is only 0-100 ℃ in a water cooling mode, so that whether the test value corresponding to the temperature of the cooling liquid is in the range of 0-100 or not is determined according to a plurality of test values obtained by adopting a random algorithm, and test values which are not in the range of 0-100 are removed, so that an effective test value is obtained.
And stopping generating the test value when the test value exceeds the preset test threshold value. For example, with the cooling liquid temperature 92 degrees celsius as an initial value and the preset cooling liquid step size 2 as an increasing step size, the cooling liquid temperature test value is circularly increased until the test value is equal to 100, and the test values are 92, 94, 96, 98 and 100 respectively.
It will be appreciated that the preset step size may be different for different test contents, for example, the preset step size may be 10 for vehicle speed and 2 for coolant temperature. Also, for increasing the test value and decreasing the test value, different steps may be employed, for example, the preset step may be 2 for an increase in the coolant temperature and 10 for a decrease in the coolant temperature.
Referring to fig. 3, the method further includes: and obtaining a plurality of test message addresses aiming at the same test content according to a plurality of test key value pairs corresponding to the same test content.
Taking the above-mentioned coolant temperature as an example, the coolant temperature is taken as a test content, and the test values are 92, 94, 96, 98 and 100, respectively, and the generated key value pairs are: the temperature of the cooling liquid is higher than 92 ℃, the temperature of the cooling liquid is higher than 94 ℃, the temperature of the cooling liquid is higher than 96 ℃, the temperature of the cooling liquid is higher than 98 ℃, and the temperature of the cooling liquid is higher than 100 ℃. And further obtaining a plurality of test message addresses aiming at the temperature of the cooling liquid.
In step S13, based on a pre-configured frame format, a test message in the frame format is generated according to the test message address, and the test message is sent to a CAN bus, which includes the following steps.
In step S131, based on a pre-configured frame format, a plurality of test messages for the same test content in the frame format are generated for a plurality of test message addresses corresponding to the same test content, where one test message address corresponds to one test message.
Along the description of the above embodiments, for a plurality of test message addresses of the coolant temperature, a test message corresponding to the coolant temperature greater than 92 degrees celsius, a test message corresponding to the coolant temperature greater than 94 degrees celsius, a test message corresponding to the coolant temperature greater than 96 degrees celsius, a test message corresponding to the coolant temperature greater than 98 degrees celsius, and a test message corresponding to the coolant temperature greater than 100 degrees celsius are generated based on a pre-configured frame format, respectively.
In step S132, the plurality of test messages corresponding to the same test content are sequentially sent to the CAN bus according to a preset sending rule.
Optionally, the sending sequence of the test message may be determined according to the timestamp generated by the test message, and then the test message is sent sequentially according to the sending sequence. For example, the earlier the time of generation of the timestamp characterization, the earlier the transmission order, and the earlier the transmission order. The priority can also be determined according to the magnitude of the test value, for example, the higher the alarm degree represented by the larger the test value is, the higher the transmission priority is, and the transmission sequence of the test message is further determined according to the priority. For example, the higher the priority, the earlier the transmission. Therefore, the test message can be sent first with high alarm priority.
Taking the above-mentioned plurality of test values of the coolant temperature as an example, the alarm degree of the coolant temperature being greater than 92 ℃ is smaller than the alarm degree of the coolant temperature being greater than 94 ℃, so that the transmission priority of the test message corresponding to the coolant temperature being greater than 94 ℃ is higher than the transmission priority of the coolant temperature being greater than 92 ℃.
By adopting the scheme, a plurality of test values can be generated in a random mode or a step size mode aiming at the same test content, so that a plurality of test messages are generated, and the test messages are sent at one time, so that the generation of the plurality of test messages can be automatically completed, and the convenience of testing is improved.
For the same test content, it is generally necessary to send the test message again after the normal state is restored. Thus, on the basis of the above embodiment, the plurality of test values includes one normal test value and a plurality of abnormal test values;
in specific implementation, according to a normal value range preset by test content, any test value in the normal value range is used as a normal test value, and all test values which are not in the normal value range are used as abnormal test values.
The normal value ranges preset for the test contents are different.
In step S132, according to a preset sending rule, the plurality of test messages corresponding to the same test content are sequentially sent to the CAN bus, including:
selecting any message from the test messages corresponding to the abnormal test values as an abnormal test message, and sending the abnormal test message to the CAN bus.
In the description of the embodiment described as the cooling liquid temperature, the target abnormal test message is selected from the test messages corresponding to the cooling liquid temperature being greater than 92 ℃, the cooling liquid temperature being greater than 94 ℃, the cooling liquid temperature being greater than 96 ℃, the cooling liquid temperature being greater than 98 ℃, and the cooling liquid temperature being greater than 100 ℃.
In one embodiment, the abnormal test message is selected according to the transmission priority of the test message.
And under the condition that the abnormal test message is successfully sent, sending a test message corresponding to the normal test value to the CAN bus.
The normal test message may be used to place the abnormal test message in an invalid state.
Optionally, under the condition that the message that the abnormal test message is displayed on the user equipment is received, determining that the abnormal test message is successfully transmitted, and transmitting the normal test message to the CAN bus, so that the information of alarm release is displayed on the user equipment.
And under the condition that the test messages corresponding to the normal test values are successfully sent, sending the next abnormal test message to the CAN bus until all the test messages corresponding to the abnormal test values are sent to the CAN bus.
The next abnormal test message is an abnormal test message which is not sent in the test messages of the abnormal test values.
And under the condition that the normal test message is successfully sent, for example, under the condition that the message displayed by the user equipment is received, determining that the normal test message is successfully sent, and selecting the next abnormal test message from the abnormal test message which is not sent.
Similarly, after the next abnormal test message is successfully sent, the normal test message is continuously sent until the abnormal test message is completely sent, so that the abnormal test message can be sent in a traversing way.
In general, the message ID of the CAN message may include the message IDs of a plurality of alarm contents, so that the test message may carry a test message of a plurality of test contents in the test message, so as to simulate the situation that a plurality of alarm contents are reported at the same time.
On the basis of the above embodiment, the number of test contents is plural, one test content corresponds to one test message address, and in step S13, the generating, based on a pre-configured frame format, a test message in the frame format according to the test message address includes:
And determining a target frame structure of a test message address corresponding to each test content in a data frame of the frame format based on a pre-configured frame format, wherein the data frame of the frame format comprises a plurality of frame structures for carrying the test message addresses.
Specifically, the pre-configured frame format may pre-configure the message addresses corresponding to the corresponding alarm content in different frame structures of the data frame, so as to carry the test message addresses corresponding to the different alarm content in the frame structures.
Illustratively, the frame structure of the 3 rd to 5 th data bits in the data frame of the frame format is a vehicle speed alarm, and the frame structure of the 6 th to 8 th data bits in the data frame of the frame format is a cooling liquid temperature alarm. Aiming at the vehicle speed alarm test in the test content, determining that the target frame structure of the data frame of the frame format of the vehicle speed test message address corresponding to the vehicle speed is the frame structure of the 3 rd to 5 th data bits, and aiming at the cooling liquid temperature alarm test in the test content, determining that the target frame structure of the data frame of the frame format of the data frame of the cooling liquid temperature test message address corresponding to the cooling liquid temperature is the frame structure of the 6 th to 8 th data bits.
And filling each test message address into the frame format according to the target frame structure, and generating the test message under the frame format.
According to the embodiment, the frame structure with the 3 rd to 5 th data bits is used as a target frame structure, the vehicle speed test message address is added into the frame format, the frame structure with the 6 th to 8 th data bits is used as a target frame structure, the cooling liquid temperature test message address is added into the frame format, and the test message comprising the vehicle speed alarm and the cooling liquid temperature alarm under the frame format is generated. It can be seen that the test message includes both a vehicle speed test message address and a coolant temperature test message address.
By adopting the technical scheme, the test message address corresponding to the plurality of test contents can be included in the same test message, the test message can be sent to the plurality of test contents at the same time, and the test efficiency of the test message is improved.
It should be noted that, if the test values corresponding to the test contents are randomly generated, or the test values continuously changed, although the key value pair corresponding to each signal value can be traversed, the data size of the test message is larger, and more test values in the test message with larger data size may not be generated in the real state, so that more invalid test data exists.
On the basis of the above embodiment, in step S11, the step of calling a pre-configured signal value rule for the acquired test content to generate a text description and a test value corresponding to the test content includes:
And acquiring current test environment information. Specifically, the test environment is used for representing the current environment temperature, environment humidity and vehicle state, so that the test content is alarm content generated by simulating the actual vehicle under different environment conditions.
And calling a preset signal value rule aiming at the acquired test content to generate a text description and a test value corresponding to the test environment information.
For the test content, the test value of the test content is only performed for the alarm content meeting the current test environment, but not for the alarm content not meeting the current test environment.
For example, in the case where the ambient temperature is 40 degrees celsius or more, the test value is performed only for the coolant temperature being higher than the high temperature alarm threshold value, and the test value is not performed for the coolant temperature being lower than the low temperature alarm threshold value.
Thus, the test content is alarm content which can actually appear under different environmental conditions of the simulated vehicle, and further the process of generating an alarm message by the simulated alarm content is simulated. Invalid test data in the test message can be reduced, so that the data volume is reduced, and the accuracy of test message generation is improved.
