[0028] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0030] It should be noted that the acquisition, storage, use and processing of data in the embodiments of the present application are in compliance with the relevant provisions of national laws and regulations.

[0031] The Electronic Control Unit (ECU) is used to represent the vehicle-mounted module that controls the vehicle by collecting and exchanging data with various sensors and buses. It is used to judge and control the vehicle status. ECU can be divided into different types according to the difference in the functions it implements, such as Body Control Module (BCM) and Battery Management System (BMS).

[0032] Controller Area Network (CAN) is a fieldbus based on the ISO (International Organization for Standardization) internationally standardized serial communication protocol. In the automotive application field, it is used to achieve real-time and reliable data communication between various nodes or modules, thereby achieving information sharing between multiple vehicle modules.

[0033] Controller Area Network Bus Development Environment (CAN open environment, CANoe) is used to represent the development environment designed for automotive bus development.

[0034] Programmable power supply (PPS) is used to indicate that program control is used to achieve soft start, stop, voltage and current control, thereby avoiding impact and damage to the instrument.

[0035] CAPL (Communication Access Programming Language) is used to represent a high-level scripting language dedicated to writing CAN bus communication applications, that is, the CAPL scripting language can be used for CAN bus applications developed using CANoe software. The execution of program blocks in CAPL is controlled by events. CAPL programs are developed and compiled in a dedicated editor to access all objects (messages, signals, environment variables) and system variables contained in the database.

[0036] With the development of science and technology, the automotive industry is also developing rapidly. The equipment in the car is becoming more and more intelligent, and there are more and more types of vehicle-mounted modules, such as GPS (Global Positioning System) positioning module, communication module, display module, audio module and driving recorder module. In order to cope with the complex vehicle-mounted environment, it is necessary to test the communication performance of the vehicle-mounted module to determine whether it will fail during long-term operation, so as to reduce safety hazards.

[0037] In the related art, the test of the vehicle-mounted module is usually carried out in a stable power supply environment (for example, a voltage-stabilized environment). However, in the actual vehicle-mounted environment, the power supply state to the vehicle-mounted module will change with the change of factors such as the physical environment, that is, there is instability. Therefore, the test results in the related art cannot be used as a reliable reference for reducing the potential risks of the vehicle-mounted module.

[0038] In order to solve the problems of the related art, the embodiments of the present application provide a communication performance testing method, device and system.

[0039] The communication performance testing method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] Figure 1 FIG. 1 is a flow chart of a communication performance testing method 100 according to an embodiment of the present application. Figure 1 As shown, the communication performance testing method 100 may specifically include the following steps:

[0041] S101, obtaining the communicable voltage range and test requirement information of the vehicle-mounted module;

[0042] S102, determining a voltage control method that matches the test requirement information according to the communicable voltage range;

[0043] S103, controlling the power supply state of the programmable power supply to the vehicle-mounted module according to the voltage regulation method;

[0044] S104: Control the vehicle-mounted module to perform service processing in the power supply state, and obtain a test result of the communication state of the vehicle-mounted module in the power supply state.

[0045] Therefore, the voltage control method is determined based on the communicative voltage range of the on-board module and the test requirement information to control the power supply state of the programmable power supply to the on-board module. The changes in the power supply state of the on-board module in the on-board environment are taken into consideration, and the dynamic change environment of the on-board voltage is realized, that is, the actual on-board environment can be simulated more objectively; thereby, the communication performance test of the on-board module in the power supply state is realized, which effectively ensures the reliability of the test, and provides a strong basis for solving the potential hidden dangers of the on-board module.

[0046] The specific implementation methods of the above steps are introduced below.

[0047] It should be noted that the vehicle-mounted module in the embodiment of the present application may include a communication module, a control module, etc., such as an ECU, which is a vehicle-mounted module that controls the car by collecting and exchanging data with various sensors and buses. In addition, the specific type of ECU may include an engine control ECU, a seat adjustment ECU, an air conditioning control ECU, etc., which is not specifically limited in this embodiment.

[0048] In some embodiments, before step S101, connections are established with the program-controlled power supply and the CANoe hardware respectively. Specifically, the connection with the program-controlled power supply can be realized through a DB9 interface, and the DB9 interfaces can be connected through a serial signal line, and the serial signal line can use the RS232 standard to transmit data signals, thereby realizing communication based on the RS232 serial communication protocol, or using a Python script.

[0049] In addition, in some embodiments, the vehicle-mounted module is connected to CANoe hardware, and specifically, the vehicle-mounted module and the CANoe hardware can be connected by a connecting line, which is equivalent to interconnecting the programmable power supply, the vehicle-mounted module, and the CANoe hardware, so that communication can be established.

[0050] It should be understood that CANoe hardware is equivalent to a simulated vehicle module (e.g., a simulated ECU), which can be used to receive messages sent by the vehicle module under test, send messages by simulating other real vehicle modules, and monitor and check data messages, etc. Specifically, CANoe hardware can include VN1640, VN1630, or VN1670, etc.

[0051] In some embodiments, in step S101, the communicable voltage range of the vehicle-mounted module can be determined based on the simulation test database established by the simulation experiment or the historical test data in the actual vehicle-mounted environment. Taking the vehicle-mounted module to be tested as an ECU as an example, the target simulation test database or target historical test data matching the ECU is searched and determined, so as to analyze these test data to obtain the corresponding communicable voltage range, for example, 8 to 18V.

[0052] In some embodiments, the test requirement information may include simulated scenarios or simulated conditions of the vehicle environment, such as simulated long-term high load, simulated random voltage jumps, simulated power-on or simulated power-off, etc.

[0053] In some embodiments, in step S102, the voltage control method may include any of the following: voltage gradient adjustment, voltage transient, power on or power off. It can be understood that voltage gradient adjustment is to linearly control the voltage value, voltage transient is to jump the voltage value within an instant, and power on or off is to control the power state to control the voltage value.

[0054] In this way, the corresponding voltage control method can be determined according to the test requirement information. For example, if the test requirement information is to simulate random voltage jumps, the voltage control method is a voltage transient in which the voltage value jumps within an instant; and then the specific voltage control method is further determined according to the obtained communicable voltage range of the vehicle-mounted module.

[0055] In some embodiments, the voltage upper limit corresponding to the communication range and the preset percentage may be multiplied to determine the first voltage, and the voltage lower limit corresponding to the communication range and the preset percentage may be multiplied to determine the second voltage; then, according to the test requirement information, the voltage control method may be determined to be voltage gradient adjustment or voltage transient within the target voltage interval span. The target voltage interval span is the voltage interval span between the first voltage and the second voltage.

[0056] It should be noted that the preset percentage may be less than, equal to or greater than 100%, and this embodiment does not limit this.

[0057] In specific implementation, the product of the target voltage interval span and the preset accuracy can be determined as the target step length, so that the voltage gradient can be adjusted according to the target step length within the target voltage interval span. For example, the communicable voltage range of the vehicle-mounted module is 8 to 18V, the preset percentage is 100%, the preset accuracy is 0.01, then the first voltage is 18V, the second voltage is 8V, and the target step length is 0.1V. That is, the voltage control method is to adjust the voltage gradient by 0.1V between 8 and 18V.

[0058] In specific implementation, the voltage value can be regulated to an undervoltage or overvoltage state according to the target step length, and then regulated to a regulated voltage state. Specifically, the voltage can be gradually increased to a first voltage according to the target step length, and the first voltage can be gradually decreased to a regulated voltage according to the target step length; or, the voltage can be gradually decreased to a second voltage according to the target step length, and the second voltage can be gradually increased to a regulated voltage according to the target step length. For the regulated voltage, taking the communication voltage range of 8 to 18V as an example, the regulated voltage can be 12V.

[0059] In specific implementation, voltage transient regulation can be achieved by instantaneously increasing the voltage to a first voltage and instantaneously decreasing the first voltage to a regulated voltage; or, instantaneously decreasing the voltage to a second voltage and instantaneously increasing the second voltage to a regulated voltage.

[0060] In a specific implementation, the voltage can be instantaneously reduced to a third voltage, the value of which is 0. It can be understood that the voltage value instantaneously becomes zero in the control mode based on power off.

[0061] In addition, in the related art, the power supply state of the vehicle-mounted module is usually controlled by manually adjusting the program power supply, but the manual control has a large error and a large control gradient, which results in damage to the test environment and low accuracy of the test results. Therefore, this embodiment controls the power supply state of the program-controlled power supply to the vehicle-mounted module according to the voltage control method.

[0062] In some embodiments, in step S103, a control instruction indicating a voltage control method can be generated according to the determined voltage control method, and the control instruction can be sent to the programmable power supply to control the power supply state of the programmable power supply to the vehicle-mounted module, that is, the programmable power supply adjusts the power supply state to the vehicle-mounted module according to the control instruction.

[0063] In specific implementation, the target interface (eg, DB9 interface) encapsulated in the library corresponding to the programmable power supply can be called, so as to send control instructions to the programmable power supply through the target interface to control the power supply state of the programmable power supply to the vehicle-mounted module.

[0064] In some embodiments, in step S104, since a connection is established with the CANoe hardware in advance and thus with the vehicle-mounted module, the vehicle-mounted module can be controlled to perform business processing under a power supply state corresponding to the voltage control method.

[0065] In some embodiments, the data messages received and sent by the vehicle-mounted module can be monitored and checked to determine the stability of the message transmission, thereby testing the communication performance of the vehicle-mounted module, that is, testing the reliability of the vehicle-mounted module, and determining the stability result as the final test result. Specifically, it can include whether the message has a signal, whether an error frame occurs, whether the message signal cycle is stable, and the time from no signal to recovery to normal. It can be understood that in the undervoltage or overvoltage state, since the vehicle-mounted module cannot work, there is no message signal.

[0066] In addition, in some embodiments, a message signal ID may also be included to confirm the priority according to the ID and determine the signal to be filtered, screened or cached, so as to analyze the test results.

[0067] In addition, in some embodiments, a CAPL control script can be established based on the CANoe bus development environment to control the power supply state of the programmable power supply to the vehicle-mounted module and control the vehicle-mounted module to perform business processing under the power supply state based on the control script. In other words, the control script uses a dual-thread control mechanism, one thread is used to control the power supply state (power state and voltage), and the other thread is used to monitor and control the vehicle-mounted module to complete the corresponding business action.

[0068] Furthermore, it should be noted that the two threads do not interfere with each other and are executed synchronously. That is, the first thread controls the power supply state of the programmable power supply to the vehicle-mounted module according to the voltage regulation method; the second thread controls the vehicle-mounted module to perform business processing in the power supply state, and obtains the test result of the communication state of the vehicle-mounted module in the power supply state; wherein the first thread and the second thread are executed synchronously. In this way, the efficiency of the test can be effectively guaranteed.

[0069] Furthermore, in some embodiments, after step S104, the messages that are easily lost can be analyzed and determined based on the test results, thereby determining the specific CAN channel or LIN channel that is greatly affected by the voltage, and further analyzing the differences between the channels for subsequent optimization and fault tolerance adjustments. In other words, based on the test results, it can be determined whether the vehicle-mounted module will fail during a long period of operation, thereby reducing safety hazards.

[0070] In some embodiments, after step S104, a communication log can be further generated according to the test result. Specifically, the communication log corresponding to the test result can be generated by pre-configured CANoe software. In addition, the communication log can include the reception of the message and the change of the load, for example, the packet loss rate, the number of received message frames, the number of error frames and the load rate of the bus. In this way, when a fault occurs later, it can be located and reproduced by calling the matching communication log.

[0071] refer to Figure 2 , this application also provides another implementation method of communication performance testing.

[0072] like Figure 2 As shown, another implementation method 200 of the communication performance test provided in the present application includes the following steps: in step S201, the hardware environment is set up, that is, communication can be established by interconnecting with the programmable power supply, the vehicle-mounted module, and the CANoe hardware; in step S202, the programmable power supply is started; in step S203, the operating status of the programmable power supply is judged. If the programmable power supply operates normally, the programmable power supply can supply power to the vehicle-mounted module. If the programmable power supply cannot operate normally, return to step S202, that is, restart the programmable power supply; in step S204, the vehicle-mounted module operates based on the power supply of the programmable power supply; in step S205, the power supply status of the programmable power supply to the vehicle-mounted module is controlled according to the voltage control method, so as to obtain the test result of the communication status of the vehicle-mounted module in the power supply state.

[0073] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims.
