[0054] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the test equipment of the vehicle domain controller, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0057] The embodiment of the present invention provides a method for testing a vehicle domain controller, referring to Figure 2 , Figure 2 This is a flow chart of a first embodiment of a method for testing a vehicle domain controller according to the present invention.

[0058] In this embodiment, the vehicle domain controller testing method includes the following steps:

[0059] Step S10: Construct a virtual model of the target vehicle according to a preset test environment.

[0060] It should be understood that the execution subject of the method of this embodiment can be a test device of a vehicle domain controller with data processing, network communication and program running functions, such as a computer, or other devices or equipment that can achieve the same or similar functions. The above-mentioned vehicle domain controller test device (hereinafter referred to as the control test device) is used as an example for illustration.

[0061] It should be noted that the preset test environment can be a pre-configured test environment for control testing. The control test equipment can pre-configure the preset test environment for different operating conditions based on information such as test conditions, test requirements, and test environment parameters, thereby enabling control testing under different operating conditions and environments. The aforementioned virtual model can be a simulation model of each functional module in the target vehicle. For example, the virtual model may include the target vehicle's IO interface model, virtual controller model, signal interaction model, etc.

[0062] It should be understood that this embodiment obtains the test requirements of the target vehicle, determines the test conditions based on the test requirements, obtains the corresponding test environment parameters, builds a preset test environment based on the test conditions and test environment parameters, obtains the vehicle parameters of the target vehicle, and builds a virtual model of each functional module in the target vehicle based on the vehicle parameters under the preset test environment, thereby completing the construction of the test environment and test object for the control test, effectively improving the efficiency and accuracy of subsequent tests.

[0063] Step S20: Generate a control strategy according to the test requirements of the domain controller to be tested of the target vehicle.

[0064] It should be noted that the domain controller under test can be the domain controller in the target vehicle that requires control behavior testing, such as a chassis domain controller or a powertrain domain controller. The aforementioned control strategy can be a strategy for controlling the test equipment to simulate control behavior by controlling a virtual model through the domain controller under test of the target vehicle. For example, the control strategy can include signal interaction control, signal conversion control, and control request transmission.

[0065] It should be understood that this embodiment controls the test equipment to pass the test requirements of the domain controller to be tested of the target vehicle, determines the control behavior to be tested of the domain controller to be tested according to the test requirements, and generates a control strategy according to the control behavior to be tested.

[0066] For example, the control test equipment obtains the test requirements of the domain controller to be tested, and determines the control behavior to be tested according to the test requirements, including: simulating the state changes of the intelligent driving trigger switch and the emergency stop switch of the real vehicle, simulating the operation of the accelerator pedal and other driver operations, and generates a control strategy based on the control behavior to be tested, which is to control the IO interface model of the target vehicle through the domain controller to be tested to simulate the state changes of the intelligent driving trigger switch and the emergency stop switch of the real vehicle; and to control the virtual controller model through the domain controller to be tested to simulate the operation of the accelerator pedal and other driver operations.

[0067] Step S30: controlling the virtual model through the domain controller to be tested according to the control strategy.

[0068] It should be understood that the control test equipment in this embodiment determines the module model corresponding to each control behavior to be tested according to the control strategy, and controls each module model through the domain controller to be tested according to the control strategy.

[0069] Furthermore, in order to effectively control the virtual model, the above step S30 may include:

[0070] generating a control request through the domain controller to be tested according to the control policy;

[0071] Performing signal conversion on the control request by the domain controller to be tested to obtain a target signal;

[0072] The virtual model is controlled by the domain controller to be tested according to the target signal.

[0073] In the specific implementation, the control test equipment performs vehicle intelligent driving trigger and emergency stop control logic judgment on the hard-wired input signals such as the intelligent driving trigger switch and emergency stop switch output signals of the IO interface model through the domain controller to be tested according to the control strategy; performs throttle pedal signal acquisition and signal conversion on the hard-wired input signals such as the accelerator pedal of the IO interface model simulation output signal through the domain controller to be tested according to the control strategy; sends the brake pedal opening to the virtual controller model electronic brake system controller EBS through the domain controller to be tested according to the control strategy for brake pedal signal conversion; sends the intelligent driving mode status, wire-controlled throttle request, wire-controlled brake request, and wire-controlled gear request CAN signals to the virtual controller model automatic driving controller ADU through the domain controller to convert the vehicle wire-controlled request signal according to the control strategy; calculates the relevant status of the intelligent driving control of the whole vehicle through the domain controller to be tested based on internal signal acquisition and signal conversion, and converts the intelligent driving control according to the intelligent driving The trigger switch collects signals and sends the intelligent driving trigger status and other signals to the ADU through CAN, and converts the opening according to the collected voltage of the accelerator pedal, and sends the accelerator pedal opening to the ADU through CAN for manual takeover; the domain controller to be tested sends the wire-controlled gear request CAN signal to the transmission controller TCU for gear control according to the ADU; the domain controller to be tested collects the accelerator pedal voltage (normal driving) and the ADU wire-controlled throttle / torque request (intelligent driving driving), and converts it into the accelerator pedal voltage after comprehensively judging the current intelligent driving mode status, and gives it to the vehicle controller VCU for drive control; the domain controller to be tested forwards the ADU wire-controlled braking request (intelligent driving braking) to the EBS for brake pedal signal conversion, and sends the brake pedal opening (normal driving / intelligent driving braking) sent by EBS, and converts it into the brake pedal voltage after comprehensively judging the current intelligent driving mode status, and gives it to the vehicle controller VCU for braking control.

[0074] Step S40: determining the target control state of the virtual model according to the control strategy, and obtaining the current control state of the virtual model after control.

[0075] It should be noted that the current control state can be the current state of the virtual model after being controlled by the domain controller under test. For example, the domain controller under test simulates emergency braking of a vehicle, obtains the current braking state of the virtual model, and checks whether the current braking state is consistent with the expected state. The target control state can be the expected state corresponding to the control behavior in the control strategy.

[0076] Step S50: Compare the current control state with the target control state, and determine the test result of the domain controller to be tested according to the comparison result.

[0077] It should be understood that in order to accurately determine whether the control behavior of the domain controller under test is consistent with expectations, the control test equipment of this embodiment determines the target control state of the virtual model according to the control strategy and obtains the current control state of the virtual model after control. For example, it determines whether the DCU control drive logic, such as intelligent driving triggering, emergency stop switch request and message output, is consistent, determines whether the DCU signal interaction and signal conversion are correct, and sends signals to relevant devices to realize intelligent driving related function control.

[0078] Furthermore, in order to effectively optimize the test, after the above step S50, the following steps may be included:

[0079] Adjusting the preset test environment according to the test results;

[0080] Rebuilding the virtual model of the target vehicle according to the adjusted preset test environment;

[0081] The control strategy is modified according to the test result, and the process returns to the step of controlling the virtual model through the domain controller to be tested according to the control strategy.

[0082] It should be understood that during the test process, the control test equipment can promptly correct the test parameters and return the test data and test conclusions in a timely manner according to the test results, so as to optimize the control strategy. It can also build automated test cases and sequences under different working conditions based on test conditions, test environment parameters and other information, generate automated test reports, etc., so as to carry out large-scale and repeated working condition tests.

[0083] This embodiment constructs a virtual model of the target vehicle according to a preset test environment, generates a control strategy according to the test requirements of the domain controller to be tested of the target vehicle, controls the virtual model through the domain controller to be tested according to the control strategy, determines the target control state of the virtual model according to the control strategy, obtains the current control state of the virtual model after control, compares the current control state with the target control state, and determines the test result of the domain controller to be tested according to the comparison result; Since this embodiment constructs the virtual model of the target vehicle according to the preset test environment, thereby constructing a virtual test environment, according to the test requirements of the domain controller to be tested of the target vehicle A control strategy is generated, and the virtual model is controlled by the domain controller to be tested according to the control strategy, thereby simulating the control behavior of the domain controller to be tested of the target vehicle, determining the target control state of the virtual model according to the control strategy, and obtaining the current control state of the virtual model after control, comparing the current control state with the target control state, and determining the test result of the domain controller to be tested according to the comparison result, thereby completing the control test of the domain controller to be tested. Since this embodiment controls the virtual model by controlling the domain controller to be tested, it not only ensures the accuracy of the control test, but also effectively reduces the test cost and test difficulty.

[0084] refer to Figure 3 , Figure 3 This is a flow chart of a second embodiment of a method for testing a vehicle domain controller according to the present invention.

[0085] Based on the above first embodiment, in this embodiment, step S20 includes:

[0086] Step S21: determining a target domain to be tested in the target vehicle.

[0087] It should be noted that the target domain can be a functional domain in the target vehicle that needs to be tested, wherein each functional domain in the target vehicle corresponds to a different domain controller, and each functional domain contains multiple functional modules. For example, the functional domain can be a chassis functional domain, an assisted driving functional domain, a powertrain functional domain, a body functional domain, and a cockpit functional domain. In order to effectively control the multiple functional modules contained in the target vehicle, each functional module is classified and controlled according to the classification results, so that the multiple functional modules in the vehicle can work in an orderly and coordinated manner. For example, the control test equipment determines that the cockpit function of the target vehicle needs to be tested based on the test requirements, so the cockpit functional domain is used as the target domain to be tested.

[0088] Step S22: Determine the domain controller to be tested of the target vehicle according to the target domain.

[0089] It should be understood that, in this embodiment, the control test equipment determines the domain controller corresponding to the target domain according to the function of the target domain, and uses the domain controller as the domain controller to be tested of the target vehicle.

[0090] Step S23: Determine the test requirements of the domain controller to be tested according to the target domain.

[0091] It should be noted that the test requirement may be a test requirement for testing the functionality of the domain controller to be tested. For example, the test requirement may be a test for whether the domain controller to be tested can perform signal interaction and signal conversion normally.

[0092] Step S24: Generate a control strategy according to the test requirements.

[0093] It should be understood that this embodiment controls the test equipment to pass the test requirements of the domain controller to be tested of the target vehicle, determines the control behavior to be tested of the domain controller to be tested according to the test requirements, and generates a control strategy according to the control behavior to be tested.

[0094] For example, the control test equipment obtains the test requirements of the domain controller to be tested, and determines the control behavior to be tested according to the test requirements, including: simulating the state changes of the intelligent driving trigger switch and the emergency stop switch of the real vehicle, simulating the operation of the accelerator pedal and other driver operations, and generates a control strategy based on the control behavior to be tested, which is to control the IO interface model of the target vehicle through the domain controller to be tested to simulate the state changes of the intelligent driving trigger switch and the emergency stop switch of the real vehicle; and to control the virtual controller model through the domain controller to be tested to simulate the operation of the accelerator pedal and other driver operations.

[0095] Furthermore, in order to effectively generate the control strategy, the above step S24 may include:

[0096] Step S241: determining the function to be tested of the target domain according to the test requirement;

[0097] Step S242: determining the control behavior to be tested of the domain controller to be tested according to the function to be tested;

[0098] Step S243: generating a control strategy according to the control behavior to be tested.

[0099] It should be noted that the function to be tested can be the function required to be tested by each functional module in the target domain. For example, the test requirement can be the requirement to test the execution of an action, by setting the intelligent driving trigger switch through the controller of the domain to be tested; or it can be a test of autonomous driving drive, by setting the ADU through the controller of the domain to be tested to send a wire-controlled gear position request. The above-mentioned control behavior to be tested can be the response behavior corresponding to the function to be tested. For example, to simulate the logic judgment of the vehicle's emergency stop mechanism, the control behavior to be tested can be outputting the emergency stop switch signal light to the IO interface model.

[0100] Furthermore, in order to improve the testing efficiency, the above step S242 may include:

[0101] Step S2421: calling a pre-built control behavior library according to the target domain;

[0102] Step S2422: matching each control behavior in the control behavior library according to the function to be tested;

[0103] Step S2423: using the control behavior matched in the control behavior library as the control behavior to be tested of the domain controller to be tested.

[0104] It should be noted that the control behavior library can be a pre-built custom action library, and by constructing the control behavior in advance, it is possible to directly call the relevant data information of the control behavior during the test process.

[0105] It should be understood that in order to effectively improve test efficiency, the control test equipment of this embodiment can establish a custom action library of major actions based on the needs of setting up automated test sequences, which can be directly called by setting up automated test sequences for other functions. For example, based on this functional test, an action library can be established to set request signals such as setting intelligent driving triggers and setting entry into manual mode. An action library can also be established to check the status of intelligent driving mode and the status of manual takeover, etc.

[0106] Furthermore, in order to perform the control test in an orderly manner during the test process, the above step S243 may include:

[0107] Step S2431: determining the test weight of each control behavior to be tested according to the test requirements;

[0108] Step S2432: sorting the control behaviors to be tested according to the test weights;

[0109] Step S2433: generating a test sequence according to the sorting result and the control behavior to be tested;

[0110] Step S2434: Generate a control strategy according to the test sequence.

[0111] It should be noted that the test weight may be the importance of each control behavior to be tested. For example, the weight of the braking control behavior is greater than the weight of the cockpit function control behavior.

[0112] In the specific implementation, the control test equipment controls the virtual model through the domain controller to be tested, sets the test initialization, sets the execution action, then determines whether the test results are consistent with expectations, then sets the test reset, and finally generates a test report.

[0113] This embodiment determines the target domain to be tested in the target vehicle, determines the domain controller to be tested of the target vehicle based on the target domain, determines the test requirements of the domain controller to be tested based on the target domain, and generates a control strategy based on the test requirements. Since this embodiment locates the target domain to be tested in the target vehicle, thereby locating the domain controller to be tested, and then determines the test requirements of the domain controller to be tested based on the functional information of the target domain, the control strategy of the domain controller to be tested is accurately generated, thereby effectively improving the test efficiency.

[0114] In addition, an embodiment of the present invention further provides a storage medium storing a test program for a vehicle domain controller. When the test program for the vehicle domain controller is executed by a processor, the steps of the vehicle domain controller test method described above are implemented.

[0115] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here.

Since this embodiment controls the virtual model by controlling the domain controller to be tested, it not only ensures the accuracy of the control test, but also effectively reduces the test cost and test difficulty.
