Description

Technical Field

[0001] This invention relates to the field of functional testing technology, and in particular to a CANoe-based method and apparatus for functional testing of domain controllers. Background Technology

[0002] During the development of domain controller functions, it is often necessary to perform functional tests on the developed domain controllers to ensure that each developed domain controller can operate according to the preset functions and that there is no interference between the functions.

[0003] Conventional domain controller functional testing methods include voltage testing. This involves inputting a preset operating voltage to the domain controller and using an oscilloscope to detect the output voltage at the corresponding target test point. The output voltage waveform displayed on the oscilloscope is then manually analyzed to determine if the domain controller is effectively operating its corresponding function. However, during functional testing, fluctuations in the domain controller's output voltage waveform are common, or the controller may fail to stably output the target voltage waveform for effective function operation. In such cases, relying solely on manual analysis is insufficient to accurately determine the domain controller's operational status. Consequently, it becomes impossible to promptly identify when the domain controller is failing to effectively operate its corresponding function, impacting the development efficiency of subsequent functions.

[0004] Therefore, it is particularly important to propose a technical solution to improve the accuracy of domain controller functional testing. Summary of the Invention

This enhances the efficiency and accuracy of determining whether the domain controller is operating normally, and also improves the efficiency of developing other functions of the domain controller. Detailed descriptions follow.

[0095] Example 1

[0096] Please see Figure 1 , Figure 1 This is a flowchart illustrating a CANoe-based domain controller functional testing method disclosed in an embodiment of the present invention. Wherein, Figure 1 The described CANoe-based domain controller functional testing method can be applied to domain controller functional testing systems, as well as to functional testing benches or systems for corresponding domain controller application scenarios. This invention does not limit its application. Figure 1 As shown, this CANoe-based domain controller functional testing method may include the following operations:

[0097] 101. According to the preset functional test strategy, control the low-voltage programmable power supply to output the corresponding target test voltage to the domain controller and CANoe device, so as to power the domain controller and CANoe device through the target test voltage. The preset functional test strategy is used to adjust the voltage value of the target test voltage.

[0098] In this embodiment of the invention, the target test voltage serves not only to power the domain controller and CANoe device, but also to adjust the target test voltage according to the aforementioned preset functional test strategy in a specified functional test scenario, and to determine the communication message interaction results between the domain controller and the CANoe device based on the adjusted target test voltage. It should be noted that all obtained communication message interaction results are not limited to those obtained by adjusting the target test voltage. For example, when the communication message interaction results include the duration of the first frame transmission, the results can still be obtained without adjusting the target test voltage.

[0099] CANoe (CAN open environment) refers to a bus development environment, including CANoe software and CANoe devices.

[0100] A domain controller is used to represent the integration of separate ECUs (Electronic Control Units) with the same function or similar application scenarios into a more powerful processor hardware platform. Generally speaking, a domain controller includes a domain processor, operating system, application software, and upper-level algorithms.

[0101] In this embodiment of the invention, the executing entity can be a mobile terminal, including but not limited to PC, mobile phone, tablet computer, vehicle terminal equipment, intelligent connected device, etc.

[0102] In embodiments of the present invention, such as Figure 6 As shown, optionally, the first terminal of the mobile terminal is electrically connected to the first terminal of the low-voltage programmable power supply, the second terminal of the low-voltage programmable power supply is electrically connected to the first terminal of the domain controller and the first terminal of the CANoe device, the second terminal of the domain controller is electrically connected to the second terminal of the CANoe device, and the third terminal of the CANoe device is electrically connected to the second terminal of the mobile terminal.

[0103] The mobile terminal is used to control a low-voltage programmable power supply to output a corresponding target test voltage to the domain controller and CANoe devices via the CAPL function in the CANoe software and the RS232 wiring harness. This target test voltage powers the domain controller and CANoe devices through their I / O ports. Furthermore, according to a preset functional test strategy, the mobile terminal adjusts the target test voltage output to the domain controller and CANoe devices via the CAPL function in the CANoe software and the RS232 wiring harness to determine the communication message interaction results between the domain controller and the CANoe devices. These communication message interaction results are fed back to the mobile terminal by the CANoe devices via the USB wiring harness.

[0104] The domain controller is used to send a second message to the CANoe device via the CANL and CANH ports.

[0105] The CANoe device is used to send the first message to the domain controller via the CANL and CANH ports.

[0106] 102. After the low-voltage programmable power supply provides the target test voltage to the domain controller and CANoe device, determine the communication message exchange results between the domain controller and the CANoe device.

[0107] In this embodiment of the invention, the communication message interaction result may include the duration of the first frame message transmission, and further may include the communication stop voltage and the communication recovery voltage.

[0108] In this embodiment of the invention, as an optional implementation, determining the communication message interaction results between the domain controller and the CANoe device may include the following operations:

[0109] The CANoe device is controlled to send a first message to the domain controller, which triggers the domain controller to continuously send a second message to the CANoe device.

[0110] The communication message interaction result between the CANoe device and the domain controller is determined based on the time interval between the sending time of the first message and the sending time of the first second message.

[0111] The communication message interaction result includes at least the duration of the first frame message transmission, which is equal to the interval between the transmission time of the first message and the transmission time of the first second message.

[0112] In this optional embodiment, specifically, the CAPL function RS232send() in the CANoe software can be used to control the low-voltage programmable power supply to output a voltage of approximately 13V (with an error range of ±0.5V) to the domain controller. This domain controller includes, but is not limited to, one of the following: powertrain domain controller, chassis domain controller, intelligent cockpit domain controller, or autonomous driving domain controller. Specifically, it can include domain controllers such as BMS (Battery Management System), LMU (Location and HD-MAP Unit), and DMS (DriverMonitor System). The CANoe device is then started, and real-time message monitoring is performed through the Trace window. The CANoe device is controlled to simulate sending a wake-up message 453 to the domain controller until the first frame message 372 sent by the domain controller is detected on the Trace. The time of sending the first frame message 372 is then subtracted from the time of the first send of the wake-up message 453, i.e., the duration of the first frame message transmission.

[0113] In this optional embodiment, the first message is used to represent a message sent by the CANoe device to the domain controller, and the second message is used to represent a message sent by the domain controller to the CANoe device. The number of the first message and the number of the second message are greater than or equal to 1, and the types of the first message and the second message are greater than or equal to 1. For example, the first message is 453, and the second message is 372, 373, or 374.

[0114] In this optional embodiment, optionally, while the domain controller is continuously sending the second message to the CANoe device, the CANoe device is also periodically / non-periodically sending the first message to the domain controller.

[0115] As can be seen, implementing this optional embodiment can send a first message to the domain controller via the CANoe device, triggering the domain controller to continuously send a second message to the CANoe device, thereby determining the duration of the first frame message transmission between the CANoe device and the domain controller. This can improve the accuracy of determining the domain controller's communication efficiency, thereby improving the accuracy of the domain controller's functional testing. It is also beneficial to improve the accuracy of determining the real-time functional operating status of the domain controller, as well as the efficiency and accuracy of determining whether the domain controller is operating normally. In turn, it is beneficial to improve the development efficiency of other functions of the domain controller in the future.

[0116] In this optional embodiment, as an optional implementation, controlling the low-voltage programmable power supply to output the corresponding target test voltage to the domain controller and CANoe device according to the preset functional test strategy may include the following operations:

[0117] According to the preset functional test strategy, the low-voltage programmable power supply is controlled to output a target test voltage of the first voltage value to the domain controller and CANoe device.

[0118] Based on the preset voltage decrease step size and the first voltage value, the low-voltage programmable power supply is controlled to output a target test voltage with a second voltage value that matches the preset voltage decrease step size to the domain controller and CANoe device. The second voltage value is less than the first voltage value.

[0119] In addition, determining the communication message exchange results between the CANoe device and the domain controller also includes:

[0120] Determine whether the domain controller has stopped sending the second message to the CANoe device. When it is determined that the domain controller has stopped sending the second message to the CANoe device, determine the first target time when the domain controller stops sending the second message to the CANoe device, and determine the third voltage value of the target test voltage corresponding to the first target time. Also, determine the communication message interaction result between the CANoe device and the domain controller based on the third voltage value.

[0121] The communication message exchange result also includes the communication stop voltage value, which is equal to the third voltage value.

[0122] In this optional embodiment, specifically, the low-voltage programmable power supply can be controlled to output a 9V voltage to the domain controller via the CAPL function RS232send() in the CANoe software, and gradually decrease the voltage in 0.1V steps until no second message is sent in the Trace window. The corresponding voltage value at this time is the communication stop voltage.

[0123] As can be seen, implementing this optional embodiment can adjust the voltage value of the target test voltage according to the preset functional test strategy to determine the first target time when the domain controller stops sending the second message to the CANoe device, and thus determine the communication stop voltage of the domain controller. This can improve the accuracy of determining the domain controller's communication voltage operating range, thereby improving the accuracy of the domain controller's functional test. It is also beneficial to improve the accuracy of determining the real-time functional operating status of the domain controller, and to improve the efficiency and accuracy of determining whether the domain controller is operating normally. This, in turn, is beneficial to improving the development efficiency of other functions of the domain controller in the future.

[0124] In this optional embodiment, as another optional implementation, after determining the communication message interaction result between the CANoe device and the domain controller based on the third voltage value, the method may further include the following operations:

[0125] After a preset time, based on the preset voltage increment step and the third voltage value, the low-voltage programmable power supply is controlled to output a target test voltage with a fourth voltage value that matches the preset voltage increment step and is greater than the third voltage value to the domain controller and CANoe device.

[0126] Determine whether the domain controller resends the second message to the CANoe device. When it is determined that the domain controller resends the second message to the CANoe device, determine the second target time when the domain controller resends the second message to the CANoe device, determine the fifth voltage value of the target test voltage corresponding to the second target time, and determine the communication message interaction result between the CANoe device and the domain controller based on the fifth voltage value.

[0127] The communication message interaction result also includes the communication recovery voltage value, which is equal to the fifth voltage value.

[0128] In this optional embodiment, the preset voltage increment step can optionally be 0.1V.

[0129] As can be seen, implementing this optional embodiment can further adjust the target test voltage value based on the determined domain controller communication stop voltage, in order to determine the second target time when the domain controller resends the second message to the CANoe device, and thus determine the domain controller's communication recovery voltage. This can further improve the accuracy of determining the domain controller's communication voltage operating range, thereby improving the accuracy of the domain controller's functional testing, which is beneficial to improving the accuracy of determining the domain controller's real-time functional operating status, and also beneficial to improving the efficiency and accuracy of determining whether the domain controller is operating normally. This, in turn, is beneficial to improving the development efficiency of subsequent domain controller functions.

This can improve the accuracy of the functional test of the domain controller and the accuracy of determining the real-time functional operating status of the domain controller. In this way, it can improve the efficiency and accuracy of determining whether the domain controller is operating normally, and is also conducive to improving the development efficiency of other functions of the domain controller in the future.

This invention does not limit its application. Figure 2 As shown, this CANoe-based domain controller functional testing method may include the following operations:

[0134] 201. According to the preset functional test strategy, control the low-voltage programmable power supply to output the corresponding target test voltage to the domain controller and CANoe device, so as to power the domain controller and CANoe device through the target test voltage. The preset functional test strategy is used to adjust the voltage value of the target test voltage.

[0135] 202. After the low-voltage programmable power supply provides the target test voltage to the domain controller and CANoe device, determine the communication message exchange results between the domain controller and the CANoe device.

[0136] For other descriptions of steps 201 and 202 in this embodiment of the invention, please refer to the detailed description in Embodiment 1. These descriptions will not be repeated here.

[0137] 203. Determine whether there are target interaction results in the communication message interaction results that do not meet the preset functional conditions.

[0138] In this embodiment of the invention, as an optional implementation, the above-mentioned determination of whether there is a target interaction result in the communication message interaction result that does not meet the preset functional conditions may include the following operations:

[0139] Determine whether the transmission duration of the first frame message meets the preset duration condition. If it is determined that the transmission duration of the first frame message does not meet the preset duration condition, then it is determined that the target interaction result exists in the communication message interaction result.

[0140] If it is determined that the duration of the first frame message meets the preset duration condition, then it is determined that there is no target interaction result in the communication message interaction result.

[0141] Optionally, determining whether the transmission duration of the first frame meets the preset duration condition may include:

[0142] Determine whether the target duration value corresponding to the first frame message transmission duration exceeds the range of the first frame message transmission duration. If the target duration value exceeds the range of the first frame message transmission duration, it is determined that the first frame message transmission duration does not meet the preset duration condition. If the target duration value does not exceed the range of the first frame message transmission duration, it is determined that the first frame message transmission duration meets the preset duration condition.

[0143] Furthermore, when it is determined that the target duration value exceeds the range of the first frame message transmission duration, the type of the target duration value exceeding the range of the first frame message transmission duration can be determined. This type is used to indicate that the target duration value exceeds the upper limit and / or lower limit of the range of the first frame message transmission duration.

[0144] As can be seen, implementing this optional embodiment can determine whether there are target interaction results that do not meet the preset functional conditions in the communication message interaction results after obtaining the communication message interaction results by judging whether the sending duration of the first frame message meets the preset duration condition. This facilitates the determination of the cause of the target interaction result in subsequent testing, and thus proposes functional testing optimization schemes and functional debugging optimization schemes for the domain controller. This is beneficial to improving the accuracy of functional testing of the domain controller and the accuracy of determining the real-time functional operating status of the domain controller.

[0145] Furthermore, the aforementioned functional anomaly factors that determine whether the target interaction result does not meet the preset functional conditions may include the following operations:

[0146] To determine whether the communication message exchange link meets the abnormal communication connection conditions, the communication message exchange link includes software configuration links and hardware configuration links, such as... Figure 6 As shown, the hardware configuration link includes CANoe devices, low-voltage programmable power supplies, and domain controllers.

[0147] When it is determined that the communication message interaction link meets the abnormal communication connection conditions, the first verification information of the target connection node corresponding to each target object in the communication message interaction link and the target connection node corresponding to each target object are set, and the control CANoe device is re-triggered to send the first message to the domain controller, so as to trigger the domain controller to continuously send the second message to the CANoe device, and obtain at least one second verification information.

[0148] Determine whether there is at least one target verification message among all the second verification messages. If it is determined that there is at least one target verification message among all the second verification messages, then the target object corresponding to each target verification message is identified as a communication anomaly object. The target verification message does not match any of the first verification messages.

[0149] All communication anomalies are identified as functional anomalies where the target interaction result does not meet the preset functional conditions.

[0150] As can be seen, implementing this optional embodiment can determine the functional anomaly factor that the target interaction result does not meet the preset functional conditions by judging whether the communication message interaction link meets the abnormal communication connection conditions. This can improve the accuracy of determining the functional anomaly factor, thereby determining the cause of the target interaction result, and proposing functional test optimization schemes and functional debugging optimization schemes for the domain controller. This is beneficial to improving the accuracy of functional test of the domain controller and the accuracy of determining the real-time functional operation status of the domain controller, so that the domain controller can run the corresponding functions more completely and stably.

[0151] In this optional embodiment, the above-mentioned setting of the target connection node corresponding to each target object in the communication message interaction link and the first verification information of the target connection node corresponding to each target object may include the following operations:

[0152] An electrical detection device is installed at the connection node where each target object is electrically connected to the others in the hardware configuration link.

[0153] The first detection information is determined based on the real-time detection information from the electrical detection device.

[0154] The electrical detection device includes, but is not limited to, sensitive ammeters and voltmeters.

[0155] Furthermore, re-triggering the CANoe device to send the first message to the domain controller, thereby triggering the domain controller to continuously send the second message to the CANoe device, and obtaining at least one second authentication message may include the following operations:

[0156] The CANoe device is retried to send a first message to the domain controller, which in turn triggers the domain controller to continuously send a second message to the CANoe device in order to obtain the second detection information from the electrical detection device.

[0157] In this optional embodiment, optionally, setting the target connection node corresponding to each target object in the communication message interaction link and the first verification information of the target connection node corresponding to each target object may further include:

[0158] Set output log information at each target object in the software configuration chain.

[0159] The target objects mentioned above include, but are not limited to, classes, functions, containers, etc.

[0160] As can be seen, this optional embodiment can provide specific methods for judging whether the communication message interaction link meets the abnormal communication connection conditions from both hardware configuration link and software configuration link aspects. This can improve the accuracy of determining whether the communication message interaction link meets the abnormal communication connection conditions, thereby improving the accuracy of identifying communication abnormal objects, and thus improving the accuracy of identifying functional abnormal factors. This is beneficial to improving the accuracy of functional testing of the domain controller and the accuracy of determining the real-time functional operating status of the domain controller.

[0161] 204. When it is determined that the target interaction result exists in the communication message interaction result, the functional abnormality factor that the target interaction result does not meet the preset functional conditions is determined.

[0162] 205. Based on the functional anomaly factors, determine the functional optimization reference strategy for the domain controller.

[0163] 206. Based on the functional anomaly factor and functional optimization reference strategy, determine the functional test results corresponding to the domain controller.

[0164] 207. When it is determined that the target interaction result does not exist in the communication message interaction result, the communication message interaction result is determined as the functional test result corresponding to the domain controller.

[0165] As can be seen, the real-time embodiments of the present invention can, after obtaining the communication message interaction results, further determine whether there are target interaction results in the communication message interaction results that do not meet the preset functional conditions, thereby determining whether there are target interaction results that do not meet the preset functional conditions in the communication message interaction results. This facilitates the determination of the cause of the occurrence of the target interaction results in the subsequent testing process, and proposes functional testing optimization schemes and functional debugging optimization schemes for the domain controller. This is beneficial to improving the accuracy of functional testing of the domain controller and improving the accuracy of determining the real-time functional operating status of the domain controller.

[0166] In this embodiment of the invention, as an optional implementation, after determining the communication message interaction results between the domain controller and the CANoe device, the method may further include the following operations:

[0167] The communication voltage range is determined based on the communication stop voltage and the communication resume voltage.

[0168] Determine whether the communication voltage range matches the preset voltage range. If the communication voltage range matches the preset voltage range, then the communication message interaction result is determined as the functional test result of the domain controller.

[0169] When it is determined that the communication voltage range does not match the preset voltage range, the communication voltage configuration function is determined based on the communication voltage range, and it is determined whether the communication voltage configuration function matches the preset voltage configuration function to obtain the judgment result. Based on the judgment result, the communication voltage configuration function and the preset voltage configuration function, the functional optimization reference strategy of the domain controller is determined, and the corresponding functional test result of the domain controller is determined based on the functional optimization reference strategy.

[0170] As can be seen, implementing this optional embodiment can determine the communication voltage range by using the communication stop voltage and communication recovery voltage, and then determine the corresponding functional test results of the domain controller by using the communication voltage range. Furthermore, when the communication voltage range does not match the preset voltage range, the functional optimization reference strategy of the domain controller can be determined by the communication voltage range, which is beneficial to improving the accuracy of the functional test of the domain controller and improving the accuracy of determining the real-time functional operating status of the domain controller.

[0171] In this optional embodiment, as an optional implementation, when it is determined that the communication voltage range does not match the preset voltage range, the method may further include the following operations:

[0172] Identify the anomaly type where the communication stop voltage range does not match the preset voltage range. This anomaly type indicates that the upper limit of the communication stop voltage range does not match the upper limit of the preset voltage range and / or the lower limit of the communication stop voltage range does not match the lower limit of the preset voltage range.

[0173] When the upper limit of the communication stop voltage range is determined to be inconsistent with the upper limit of the preset voltage range, it is determined whether the target voltage value corresponding to the upper limit of the communication stop voltage range exceeds the safe operating threshold. If the target voltage value exceeds the safe operating threshold, the domain controller protection mechanism is triggered. If the target voltage value does not exceed the safe operating threshold, the operation of determining the communication voltage configuration function based on the communication voltage range is triggered.

[0174] The domain controller protection mechanisms include, but are not limited to, communication isolation, power isolation, SoC frequency reduction, and physical explosion protection.

[0175] Specifically, triggering domain controller protection mechanisms may include:

[0176] Generate a first isolation control parameter to disconnect all external interfaces of the domain controller; or generate a second isolation control parameter to put all powered modules of the domain controller into standby mode.

[0177] As can be seen, this optional real-time embodiment can further determine whether the target voltage value corresponding to the upper limit of the communication stop voltage range exceeds the safe operating threshold when the upper limit of the communication stop voltage range is determined to be inconsistent with the upper limit of the preset voltage range. When the target voltage value exceeds the safe operating threshold, the domain controller protection mechanism is triggered to prevent abnormal communication voltage of the domain controller, which could cause varying degrees of damage to the domain controller or even endanger the life and health of test personnel. This can further improve the test safety and operational stability of the domain controller, based on improving the accuracy of functional testing and the accuracy of determining the real-time functional operating status of the domain controller.

[0178] Example 3

[0179] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a domain controller functional testing device based on CANoe, as disclosed in an embodiment of the present invention. Figure 3 The CANoe-based domain controller functional testing device described herein can be applied to domain controller functional testing systems, as well as to functional testing benches or systems for corresponding domain controller application scenarios. This invention does not limit its application. Figure 3 As shown, the CANoe-based domain controller functional testing device may include:

[0180] The control module 301 is used to control the low-voltage programmable power supply to output the corresponding target test voltage to the domain controller and CANoe device according to the preset functional test strategy, so as to power the domain controller and CANoe device through the target test voltage. The preset functional test strategy is used to adjust the voltage value of the target test voltage.

[0181] The determination module 302 is used to determine the communication message interaction results between the domain controller and the CANoe device after the low-voltage programmable power supply provides the target test voltage to the domain controller and the CANoe device.

[0182] The determination module 302 is also used to determine the functional test results corresponding to the domain controller based on the communication message interaction results.

[0183] As can be seen, implementing the embodiments of the present invention can adjust the target test voltage output by the low-voltage programmable power supply to the domain controller and CANoe device according to the preset functional test strategy, and determine the communication message interaction results between the domain controller and the CANoe device based on the adjusted target test voltage, thereby determining the corresponding functional test results of the domain controller. This can improve the accuracy of the functional test of the domain controller and the accuracy of determining the real-time functional operating status of the domain controller. In this way, it can improve the efficiency and accuracy of determining whether the domain controller is operating normally, and is also conducive to improving the development efficiency of other functions of the domain controller in the future.

[0184] In this embodiment of the invention, as an optional implementation, the specific method by which the determining module 301 determines the communication message interaction results between the domain controller and the CANoe device includes:

[0185] The CANoe device is controlled to send a first message to the domain controller, which triggers the domain controller to continuously send a second message to the CANoe device.

[0186] The communication message interaction result between the CANoe device and the domain controller is determined based on the time interval between the sending time of the first message and the sending time of the first second message.

[0187] The communication message interaction result includes at least the duration of the first frame message transmission, which is equal to the interval between the transmission time of the first message and the transmission time of the first second message.

[0188] As can be seen, implementing this optional embodiment can send a first message to the domain controller via the CANoe device, triggering the domain controller to continuously send a second message to the CANoe device, thereby determining the duration of the first frame message transmission between the CANoe device and the domain controller. This can improve the accuracy of determining the domain controller's communication efficiency, thereby improving the accuracy of the domain controller's functional testing. It is also beneficial to improve the accuracy of determining the real-time functional operating status of the domain controller, as well as the efficiency and accuracy of determining whether the domain controller is operating normally. In turn, it is beneficial to improve the development efficiency of other functions of the domain controller in the future.

[0189] In this optional embodiment, as an optional implementation method, the control module 301 controls the low-voltage programmable power supply to output the corresponding target test voltage to the domain controller and CANoe device according to the preset functional test strategy in the following specific ways:

[0190] According to the preset functional test strategy, the low-voltage programmable power supply is controlled to output a target test voltage of the first voltage value to the domain controller and CANoe device.

[0191] Based on the preset voltage decrease step size and the first voltage value, the low-voltage programmable power supply is controlled to output a target test voltage with a second voltage value that matches the preset voltage decrease step size to the domain controller and CANoe device. The second voltage value is less than the first voltage value.

[0192] Furthermore, the specific method by which module 302 determines the communication message interaction results between the CANoe device and the domain controller also includes:

[0193] Determine whether the domain controller has stopped sending the second message to the CANoe device. When it is determined that the domain controller has stopped sending the second message to the CANoe device, determine the first target time when the domain controller stops sending the second message to the CANoe device, determine the third voltage value of the target test voltage corresponding to the first target time, and determine the communication message interaction result between the CANoe device and the domain controller based on the third voltage value.

[0194] The communication message exchange result also includes the communication stop voltage value, which is equal to the third voltage value.

[0195] As can be seen, implementing this optional embodiment can adjust the voltage value of the target test voltage according to the preset functional test strategy to determine the first target time when the domain controller stops sending the second message to the CANoe device, and thus determine the communication stop voltage of the domain controller. This can improve the accuracy of determining the domain controller's communication voltage operating range, thereby improving the accuracy of the domain controller's functional test. It is also beneficial to improve the accuracy of determining the real-time functional operating status of the domain controller, and to improve the efficiency and accuracy of determining whether the domain controller is operating normally. This, in turn, is beneficial to improving the development efficiency of other functions of the domain controller in the future.

[0196] In this optional embodiment, as another optional implementation, the control module 301 is further configured to, after a preset time period following the determination module 302 determining the communication message interaction result between the CANoe device and the domain controller based on the third voltage value, control the low-voltage programmable power supply to output a target test voltage of a fourth voltage value that matches the preset voltage increment step size to the domain controller and the CANoe device, wherein the fourth voltage value is greater than the third voltage value.

[0197] And, such as Figure 4 As shown, the device may further include:

[0198] The judgment module 303 is used to determine whether the domain controller should resend the second message to the CANoe device.

[0199] The determining module 302 is further configured to, when the judging module 303 determines that the domain controller resends the second message to the CANoe device, determine the second target time when the domain controller resends the second message to the CANoe device, determine the fifth voltage value of the target test voltage corresponding to the second target time, and determine the communication message interaction result between the CANoe device and the domain controller based on the fifth voltage value.

[0200] The communication message interaction result also includes the communication recovery voltage value, which is equal to the fifth voltage value.

[0201] As can be seen, implementing this optional embodiment can further adjust the target test voltage value based on the determined domain controller communication stop voltage, in order to determine the second target time when the domain controller resends the second message to the CANoe device, and thus determine the domain controller's communication recovery voltage. This can further improve the accuracy of determining the domain controller's communication voltage operating range, thereby improving the accuracy of the domain controller's functional testing, which is beneficial to improving the accuracy of determining the domain controller's real-time functional operating status, and also beneficial to improving the efficiency and accuracy of determining whether the domain controller is operating normally. This, in turn, is beneficial to improving the development efficiency of subsequent domain controller functions.

[0202] In this embodiment of the invention, as another optional implementation, the specific method by which the determining module 302 determines the functional test result corresponding to the domain controller based on the communication message interaction result includes:

[0203] Determine whether there is a target interaction result in the communication message interaction result that does not meet the preset functional conditions.

[0207] As can be seen, the real-time embodiments of the present invention can, after obtaining the communication message interaction results, further determine whether there are target interaction results in the communication message interaction results that do not meet the preset functional conditions, thereby determining whether there are target interaction results that do not meet the preset functional conditions in the communication message interaction results. This facilitates the determination of the cause of the occurrence of the target interaction results in the subsequent testing process, and proposes functional testing optimization schemes and functional debugging optimization schemes for the domain controller. This is beneficial to improving the accuracy of functional testing of the domain controller and improving the accuracy of determining the real-time functional operating status of the domain controller.

[0208] In this optional embodiment, as an optional implementation method, the specific way in which the determining module 302 determines whether there is a target interaction result in the communication message interaction result that does not meet the preset functional conditions includes:

[0209] Determine whether the transmission duration of the first frame message meets the preset duration condition. If it is determined that the transmission duration of the first frame message does not meet the preset duration condition, then it is determined that the target interaction result exists in the communication message interaction result.

[0210] If it is determined that the duration of the first frame message meets the preset duration condition, then it is determined that there is no target interaction result in the communication message interaction result.

[0211] Furthermore, the specific methods by which module 302 determines the functional anomaly factors that do not meet the preset functional conditions for the target interaction result include:

[0212] Determine whether the communication message exchange link meets the abnormal communication connection conditions. The communication message exchange link includes the software configuration link and the hardware configuration link. The hardware configuration link includes the CANoe device, the low-voltage programmable power supply, and the domain controller.

[0213] When it is determined that the communication message interaction link meets the abnormal communication connection conditions, the first verification information of the target connection node corresponding to each target object in the communication message interaction link and the target connection node corresponding to each target object are set, and the control CANoe device is re-triggered to send the first message to the domain controller, so as to trigger the domain controller to continuously send the second message to the CANoe device and obtain at least one second verification information.

[0214] Determine whether at least one target verification message exists among all the second verification messages. If at least one target verification message exists among all the second verification messages, then the target object corresponding to each target verification message is identified as a communication anomaly object. The target verification message does not match any of the first verification messages.

[0215] All communication anomalies are identified as functional anomalies where the target interaction result does not meet the preset functional conditions.

[0216] As can be seen, implementing this optional embodiment can determine the functional anomaly factor that the target interaction result does not meet the preset functional conditions by judging whether the communication message interaction link meets the abnormal communication connection conditions. This can improve the accuracy of determining the functional anomaly factor, thereby determining the cause of the target interaction result, and proposing functional test optimization schemes and functional debugging optimization schemes for the domain controller. This is beneficial to improving the accuracy of functional test of the domain controller and the accuracy of determining the real-time functional operation status of the domain controller, so that the domain controller can run the corresponding functions more completely and stably.

[0220] When it is determined that the communication voltage range does not match the preset voltage range, the communication voltage configuration function is determined based on the communication voltage range, and it is determined whether the communication voltage configuration function matches the preset voltage configuration function to obtain the judgment result. Based on the judgment result, the communication voltage configuration function and the preset voltage configuration function, the functional optimization reference strategy of the domain controller is determined, and the corresponding functional test result of the domain controller is determined based on the functional optimization reference strategy.

[0221] As can be seen, implementing this optional embodiment can determine the communication voltage range by using the communication stop voltage and communication recovery voltage, and then determine the corresponding functional test results of the domain controller by using the communication voltage range. Furthermore, when the communication voltage range does not match the preset voltage range, the functional optimization reference strategy of the domain controller can be determined by the communication voltage range, which is beneficial to improving the accuracy of the functional test of the domain controller and improving the accuracy of determining the real-time functional operating status of the domain controller.
