[0032] The following detailed description is merely exemplary in nature and is not intended to limit the disclosed technology or its application and use. Furthermore, it is not intended to be bound by any express or implied theory presented in the foregoing technical fields, background art, or the following detailed description.

[0033] In the following detailed description of the embodiments, numerous specific details are set forth in order to provide a more thorough understanding of the disclosed technology. However, it will be apparent to those skilled in the art that the disclosed technology can be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

[0034] Terms such as "comprising" and "including" indicate that, in addition to the units and steps that are directly and explicitly stated in the specification, the technical solution of the present invention does not exclude the presence of other units and steps that are not directly or explicitly stated. Terms such as "first" and "second" do not indicate the order of the units in terms of time, space, size, etc., but are merely used to distinguish the units.

[0035] It should be noted that, in the context of this invention, the term "shadow mode" refers to a situation where, during manual driving, the advanced driver assistance system and various sensors on the vehicle operate normally, but do not send commands to the vehicle actuators to actually control them.

[0036] In the following, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0037] Figure 1 This is a flowchart of a method for testing advanced driver assistance functions according to an embodiment of the present invention.

[0038] Optionally, advanced driver assistance (ADA) functions can be categorized into warning functions and control functions based on the maturity and validation level of the functional algorithms. It should be noted that the functional algorithm here represents a strategy mechanism that uses ADADA methods to describe a problem, which can be used to calculate vehicle control signals during ADADA function testing. For example, the functional algorithm may include an automatic emergency braking algorithm, which calculates brake cylinder pressure and controls vehicle speed based on that pressure; or an adaptive cruise control algorithm, which calculates vehicle acceleration and controls speed based on that acceleration. Optionally, the maturity of the functional algorithm can be determined based on accuracy and recall, where accuracy indicates the probability of false alarms and recall indicates the probability of missed alarms.

[0039] As examples, warning functions may include, but are not limited to, forward collision warning, rear collision warning, lane departure warning, blind spot collision warning, door opening warning, parking distance warning, and driver status monitoring. As examples, control functions may include, but are not limited to, automatic emergency braking, adaptive cruise control, cruise control, automatic parking, and pedestrian emergency braking.

[0040] like Figure 1 As shown, in step 101, the alert function is tested through the first test channel, and in response to the alert function passing the test in the first and second test modes, the alert function is released to the third test mode. In step 103, the control function is tested through the second test channel, and in response to the control function passing the test in the first test mode and entering the second test mode, the control function is pushed to the third test mode in the first test channel for simultaneous testing with the released alert function. Optionally, steps 101 and 103 can be executed in parallel. By simultaneously testing the released alert function and the control function that passed the test in the first test mode in the third test mode in the first test channel, the release time of the alert function can be shortened and the testing cost of the control function can be reduced.

[0041] Optionally, in step 101, releasing the alert function to the third test mode in response to the alert function passing the test in the first test mode and the second test mode may include: in the first test mode, determining that the alert function has passed the test in the first test mode in response to the accuracy rate of the alert function reaching a preset accuracy rate and the recall rate of the alert function reaching a preset recall rate; in the second test mode, determining that the alert function has passed the test in the second test mode in response to the accuracy rate of the alert function reaching a preset accuracy rate and the recall rate of the alert function reaching a preset recall rate; and releasing the alert function to the third test mode in response to determining that the alert function has passed the test in the first test mode and the second test mode.

[0042] By promptly releasing warning functions that pass the tests in the first and second test modes to the third test mode, and enabling the vehicle to respond to the warning function and execute the warning operation associated with it, the release time of the warning function can be shortened and the user's safety experience in extreme scenarios can be improved.

[0043] Optionally, one or more of software-in-the-loop testing and hardware-in-the-loop testing can be performed in the first test mode, real vehicle testing can be performed in the second test mode, and real vehicle operation can be performed in the third test mode. However, the testing methods performed in the first, second, and third test modes can be changed without departing from the spirit and scope of the invention.

[0044] In one embodiment, software-in-the-loop testing can be performed in a first test mode. In software-in-the-loop testing, the consistency between the automatically generated code and the algorithmic model used for code generation is verified. For example, the consistency between the automatically generated code and the algorithmic model used for code generation can be verified by providing the same input to both and comparing their outputs.

[0045] In another embodiment, hardware-in-the-loop testing can be performed in the first test mode. Hardware-in-the-loop testing tests the controller system, which includes hardware, underlying software, and application-layer software. For example, by connecting the controller under test to an industrial computer and running a model of the controlled object on the industrial computer, it can be verified whether the controller under test meets the design requirements.

[0046] In yet another embodiment, both software-in-the-loop testing and hardware-in-the-loop testing can be performed in the first test mode.

[0047] Optionally, during the process of pushing control functions to the third test mode in the first test channel for simultaneous testing with released warning functions, the released warning functions are run, causing the vehicle to respond to the warning functions and execute warning operations associated with them; and the control functions are tested in shadow mode. It should be noted that testing control functions in shadow mode means running the control functions but causing the vehicle not to respond to them and execute control operations associated with them. Optionally, during the shadow mode testing of control functions, the accuracy and recall rate of the control functions are monitored in the background. If the accuracy or recall rate of the control functions does not reach a preset accuracy or recall rate, scenarios of false alarms (accuracy not reaching the preset accuracy) or missed alarms (recall rate not reaching the preset recall rate) are identified. Then, through big data retrieval, the scenarios of false alarms or missed alarms are extracted and relevant sensor data is analyzed to optimize the internal algorithm and further improve the current accuracy or recall rate to the preset accuracy or recall rate.

[0048] Optionally, for alert functions, control functions can be pushed to the third test mode in the first test channel for simultaneous testing with the released alert functions. In response to the control function's accuracy reaching a preset accuracy rate and its recall reaching a preset recall rate, the control function is determined to have passed the shadow mode test.

[0049] Optionally, in step 101, the alert functions that passed the tests in the first and second test modes can be released to the third test mode via over-the-air download, thereby improving the release efficiency of the alert functions and saving the release cost. For example, the alert functions that passed the tests in the first and second test modes can be sent to the third test mode via a mobile communication over-the-air interface (e.g., via SMS, browser, etc.).

[0050] Optionally, in step 103, in the second test mode of the second test channel, the control function is determined to pass the test in the second test mode in response to the control function's accuracy reaching a preset accuracy and the control function's recall reaching a preset recall; and the control function is determined to pass the verification in response to the control function passing the shadow mode test and passing the test in the second test mode.

[0051] It is understandable that the preset accuracy and preset recall rates for alert functions can be set to be less than or equal to the preset accuracy and preset recall rates for control functions.

[0052] Optionally, different test parameters can be determined for warning functions and control functions to model the test process. These test parameters may include, but are not limited to, test duration, test scenario parameters, mileage, and fault tolerance. For example, test scenario parameters may include, but are not limited to, weather parameters (e.g., sunny, cloudy, rainy, snowy), time of day parameters (e.g., early morning, daytime, evening, night), and driving environment parameters (e.g., road geometry, road facility limitations, traffic participants, etc.).

[0053] Optionally, the fault tolerance rate for alert-type function testing can be set to be greater than that for control-type function testing, the test duration for alert-type functions can be set to be less than that for control-type functions, and the test mileage for alert-type functions can be set to be less than that for control-type functions. By determining different test parameters for alert-type and control-type functions, the release time of alert-type functions can be shortened, thereby improving testing efficiency.

[0054] The method for testing advanced driver assistance (ADA) functions according to one aspect of the present invention can classify ADADA functions into warning functions and control functions based on the maturity and verification level of the functional algorithms during the testing and verification process. It utilizes dual test channels to test both warning and control functions in parallel, thereby improving the development, deployment, and testing / verification process. By testing control functions simultaneously with the actual operation of warning functions, the release time of warning functions is shortened and the testing cost of control functions is reduced. This improves functional testing efficiency while ensuring that function release complies with design specifications and safety, and enhances the user experience of ADADA functions in actual use.

[0055] Figure 2 This is a system block diagram for testing advanced driver assistance functions according to an embodiment of the present invention. Optionally, advanced driver assistance functions can be divided into warning functions and control functions based on the maturity and verification level of the functional algorithms.

[0056] like Figure 2 As shown, the system 200 for testing advanced driver assistance functions includes a first test unit 201 and a second test unit 203. The first test unit 201 is configured to test warning functions through a first test channel and release the warning functions to a third test mode in response to the warning functions passing the test in the first test mode and the second test mode. The second test unit 203 is configured to test the control functions through a second test channel and, in response to the control functions passing the test in the first test mode and entering the second test mode, push the control functions to the third test mode in the first test channel for simultaneous testing with the released warning functions.

[0057] Optionally, the first test unit 201 can be configured to: in a first test mode, determine that the warning function passes the test in the first test mode in response to the accuracy of the warning function reaching a preset accuracy and the recall of the warning function reaching a preset recall; in a second test mode, determine that the warning function passes the test in the second test mode in response to the accuracy of the warning function reaching a preset accuracy and the recall of the warning function reaching a preset recall; and release the warning function to a third test mode in response to the determination that the warning function passes the test in the first test mode and the second test mode.

[0058] By promptly releasing warning functions that pass the tests in the first and second test modes to the third test mode, the vehicle responds to the warning function and executes the warning operation associated with it. This shortens the release time of warning functions and improves the user's safety experience in extreme scenarios.

[0059] Optionally, the first test unit 201 and the second test unit 203 can be configured to perform one or more of software-in-the-loop testing and hardware-in-the-loop testing in the first test mode, perform real-vehicle testing in the second test mode, and perform real-vehicle operation in the third test mode. However, the testing methods performed by the first test unit 201 and the second test unit 203 in the first test mode, the second test mode, and the third test mode can be changed without departing from the spirit and scope of the invention.

[0060] In one embodiment, the first test unit 201 and the second test unit 203 can perform software-in-the-loop testing in a first test mode. In software-in-the-loop testing, the consistency between automatically generated code and the algorithmic model used for code generation is verified. For example, the consistency between the automatically generated code and the algorithmic model used for code generation can be verified by providing the same input to both and comparing their outputs.

[0061] In another embodiment, the first test unit 201 and the second test unit 203 can perform hardware-in-the-loop testing in the first test mode. Hardware-in-the-loop testing tests the controller system, which includes hardware, underlying software, and application-layer software. For example, by connecting the controller under test to an industrial computer and running a model of the controlled object on the industrial computer, it can be verified whether the controller under test meets the design requirements.

[0062] In yet another embodiment, the first test unit 201 and the second test unit 203 can perform both software-in-the-loop testing and hardware-in-the-loop testing in the first test mode.

[0063] Optionally, the first test unit 201 can be configured to, in the third test mode of the first test channel,: run the released warning function to cause the vehicle to respond to the warning function and execute the warning operation associated with the warning function; and test the control function in shadow mode. It should be noted that testing the control function in shadow mode means running the control function but causing the vehicle not to respond to the control function and execute the control operation associated with the control function. Optionally, during the shadow mode testing of the control function, the accuracy and recall rate of the control function are monitored in the background. If the accuracy or recall rate of the control function does not reach the preset accuracy or recall rate, a scenario of false alarm (accuracy not reaching the preset accuracy) or missed alarm (recall rate not reaching the preset recall rate) is identified. Then, the scenarios of false alarm or missed alarm are extracted through big data retrieval and related sensor data is analyzed to optimize the internal algorithm to further improve the current accuracy or recall rate to the preset accuracy or recall rate for the warning function.

[0064] Optionally, the first test unit 201 can be configured to: in the third test mode of the first test channel, determine that the control function has passed the shadow mode test in response to the control function's accuracy reaching a preset accuracy and the control function's recall reaching a preset recall; and send a signal to the second test unit 203 indicating that the control function has passed the shadow mode test.

[0065] Optionally, the second test unit 203 can be configured to: in the second test mode of the second test channel, determine that the control function passes the test in the second test mode in response to the control function's accuracy reaching a preset accuracy and the control function's recall reaching a preset recall; receive a signal from the first test unit 201 indicating that the control function passes the shadow mode test; and determine that the control function passes the verification in response to the control function passing the shadow mode test and passing the test in the second test mode.

[0066] Optionally, the first test unit 201 can use an over-the-air download method to release the alert functions that have passed the tests in the first and second test modes to the third test mode, thereby improving the release efficiency of the alert functions and saving the release cost. For example, the first test unit 201 can send the alert functions that have passed the tests in the first and second test modes to the third test mode via a mobile communication over-the-air interface (e.g., via SMS, browser, etc.).

[0067] It is understandable that the preset accuracy and preset recall rates for alert functions can be set to be less than or equal to the preset accuracy and preset recall rates for control functions.

[0068] Optionally, the first test unit 201 and the second test unit 203 can determine different test parameters for warning functions and control functions, respectively, to model the test process. These test parameters may include, but are not limited to, test duration, test scenario parameters, mileage, and fault tolerance. For example, test scenario parameters may include, but are not limited to, weather parameters (e.g., sunny, cloudy, rainy, snowy), time of day parameters (e.g., early morning, daytime, evening, night), and driving environment parameters (e.g., road geometry, road infrastructure limitations, traffic participants, etc.).

[0069] Optionally, the fault tolerance rate for alert-type function testing can be set to be greater than that for control-type function testing, the test duration for alert-type functions can be set to be less than that for control-type functions, and the test mileage for alert-type functions can be set to be less than that for control-type functions. By determining different test parameters for alert-type and control-type functions, the release time of alert-type functions can be shortened, thereby improving testing efficiency.

[0070] The system for testing advanced driver assistance (ADA) functions according to one aspect of the present invention can classify ADADA functions into warning functions and control functions based on the maturity and verification level of the functional algorithms during the testing and verification process. It utilizes dual test channels to test both warning and control functions in parallel, thereby improving the development, deployment, and testing / verification process. By testing control functions simultaneously with the actual operation of warning functions, the release time of warning functions and the testing cost of control functions are shortened. This improves functional testing efficiency while ensuring that function release complies with design specifications and safety, and enhances the user experience of ADADA functions in actual use.

[0071] Figure 3 This is a flowchart of a method for testing advanced driver assistance functions according to an embodiment of the present invention.

[0072] Optionally, advanced driver assistance functions can be categorized into warning functions and control functions based on the maturity and validation level of their algorithms. For example, warning functions may include, but are not limited to, forward collision warning, rear collision warning, lane departure warning, blind spot collision warning, door opening warning, parking distance warning, and driver status monitoring. For example, control functions may include, but are not limited to, automatic emergency braking, adaptive cruise control, cruise control, automatic parking, and pedestrian emergency braking.

[0073] like Figure 3As shown, steps 301, 303, and 305 illustrate the process of testing alert-type functions through the first test channel, while steps 301' and 303' illustrate the process of testing control-type functions through the second test channel. Optionally, steps 301, 303, and 305 can be executed in parallel with steps 301' and 303'.

[0074] In step 301, the alert function is tested in the first test mode, and in response to the alert function's accuracy reaching a preset accuracy rate and its recall rate reaching a preset recall rate, it is determined that the alert function has passed the test in the first test mode, and then proceeds to step 303.

[0075] In step 303, the alert function is tested in the second test mode, and in response to the alert function's accuracy reaching a preset accuracy rate and its recall rate reaching a preset recall rate, it is determined that the alert function has passed the test in the second test mode, and then proceeds to step 305.

[0076] Optionally, in step 303, the alert functions that passed the tests in the first and second test modes can be released to the third test mode via over-the-air download, thereby improving the release efficiency of the alert functions and saving the release cost. For example, the alert functions that passed the tests in the first and second test modes can be sent to the third test mode via a mobile communication over-the-air interface (e.g., via SMS, browser, etc.).

[0077] In step 305, the warning function is tested in the third test mode, such that running the warning function causes the vehicle to respond to the warning function and perform a warning operation associated with the warning function.

[0078] Optionally, one or more of software-in-the-loop testing and hardware-in-the-loop testing can be performed in the first test mode, real vehicle testing can be performed in the second test mode, and real vehicle operation can be performed in the third test mode. However, the testing methods performed in the first, second, and third test modes can be changed without departing from the spirit and scope of the invention.

[0079] In step 301', the control function is tested in the first test mode, and in response to the control function's accuracy reaching a preset accuracy and the alert function's recall reaching a preset recall, it is determined that the control function has passed the test in the first test mode, and then proceeds to step 303'.

[0080] In step 303', the control functions are tested in the second test mode, and at the same time, the control functions are pushed to the third test mode in the first test channel to be tested simultaneously with the released warning functions.

[0081] In step 305, during the testing of control functions in the third test mode, the control functions are tested in shadow mode. It should be noted that testing control functions in shadow mode means running the control function but causing the vehicle not to respond to the control function in order to perform control operations associated with it. Optionally, during the shadow mode testing of control functions, the accuracy and recall rate of the control functions are monitored in the background. If the accuracy or recall rate of the control functions does not reach a preset accuracy or recall rate, it is determined that there are false alarms (accuracy not reaching the preset accuracy) or missed alarms (recall rate not reaching the preset recall rate). Then, through big data retrieval, the false alarm or missed alarm scenarios are extracted and relevant sensor data is analyzed to optimize the internal algorithm to further improve the current accuracy or recall rate to the preset accuracy or recall rate, thus alerting the relevant function.

[0082] Optionally, in step 303', in response to the control function's accuracy reaching a preset accuracy and the control function's recall reaching a preset recall, it is determined that the control function has passed the test in the second test mode.

[0083] Optionally, in step 305, the control function is determined to have passed the shadow mode test in response to the control function's accuracy reaching a preset accuracy and its recall reaching a preset recall.

[0084] Optionally, the above method further includes determining that the control class function has passed verification in response to the control class function passing the shadow mode test and passing the test in the second test mode.

[0085] For example, Figure 3 The method shown for testing advanced driver assistance functions can be applied to cone recognition and response functions, where cone recognition is a warning function and cone response is a control function.

[0086] For example, the cone recognition function can be tested through the first test channel using steps 301, 303, and 305. After the test is passed, the cone recognition function can be released and deployed to the user's vehicle in advance. This allows the vehicle to respond to the cone recognition function and perform corresponding warning operations, such as notifying the user of the presence of cones in front of the vehicle through a warning signal, thereby improving the user's safety experience in scenarios where there are cones in front of the vehicle.

[0087] For example, the cone response function can be tested via a second test channel using steps 301' and 303'. In step 301', the cone response function is tested in a first test mode, and proceeds to step 303' after the cone response function passes the test in the first test mode. In step 303', the cone response function is tested in a second test mode, and simultaneously pushed to a third test mode in the first test channel for testing concurrently with the released cone recognition function. In step 305, during the cone response function test in the third test mode, the cone response function is tested in a shadow mode, where the cone response function is activated but the vehicle does not respond to the cone response function to perform corresponding control operations. Simultaneously, during the cone response function test in shadow mode, the performance metrics of the background monitoring algorithm are analyzed, and the warning signals generated by the cone recognition function are analyzed using big data and post-hoc information to aid in internal algorithm optimization and iteration. Furthermore, the response function to the cones is verified by passing the shadow mode test and the second test mode test. At this point, the response function to the cones can be applied to actual vehicle control so that the vehicle responds to the response function to the cones to perform corresponding response operations, such as early braking.

[0088] The above methods are used to test the cone recognition and response functions. While the cone recognition function is actually running, the cone response function can be tested simultaneously, shortening the release time of the cone recognition function and reducing the testing cost of the cone response function. Therefore, this testing method improves the user experience while enabling rapid iteration and secure deployment of the cone recognition and response functions.
