[0032] The vehicles of the embodiments of the present application include but are not limited to sedans, SUVs, off-road vehicles, pickup trucks or other power-driven non-track-borne vehicles, and have the conventional structure and functions of vehicles currently on the market, which will not be specifically introduced herein.

[0033] The intelligent driving controller of the embodiment of the present application has the conventional structure, functions and algorithms of the intelligent driving function controllers currently on the market, and will not be specifically introduced in this article.

[0034] Figure 1Shown is a schematic diagram of an embodiment of the intelligent driving safety testing system of the present application. The intelligent driving safety testing system is connected to various associated systems of the vehicle, such as the steering system, the braking system, etc.

[0035] Intelligent driving functions are being applied in more and more driving scenarios in vehicles. How to ensure the safety of passengers under intelligent driving is the focus of intelligent driving function technology. However, since the faults involved in intelligent driving functions are relatively complex and difficult to reproduce in the actual vehicle test environment, the intelligent driving function test through the simulation test platform is only suitable for the verification of functional scenarios, and cannot effectively verify the actual vehicle fault problems.

[0036] In order to solve the above technical problems, this specification provides an intelligent driving safety testing system that is operational and repeatable.

[0037] By simulating various faults that may occur when users use the intelligent driving function and monitoring the response and handling methods of the intelligent driving function to various faults, the safety of the intelligent driving function can be protected in a laboratory environment, allowing the faults to be verified in large quantities and repeatedly.

[0038] In some embodiments, Figure 1 As shown, the intelligent driving safety test system includes a fault injection device 100, an intelligent driving function operation device 200 and a fault monitoring device 300; the intelligent driving function operation device is the core control unit of the test system, which is respectively connected to the fault injection device and the fault monitoring device.

[0039] The fault injection device includes at least one fault to be injected and a fault injection implementation method of the fault to be injected, including software level and hardware level.

[0040] The faults to be injected in the fault injection device described in this article are all operable and repeatable, and can simulate or replicate various fault contents in the real vehicle environment, solving the problem that it is difficult to perform various fault safety tests on the real vehicle.

[0041] The main body of the intelligent driving function operation device is an intelligent driving simulation bench, which includes various software and hardware, and can realize closed-loop simulation operation of the intelligent driving function.

[0042] The intelligent driving function operation device described in this article includes an intelligent driving controller connected to a fault injection device and a fault monitoring device.

[0043] The fault monitoring device includes at least one monitoring method for the intelligent driving function to respond to various faults to be injected, and the monitoring method includes software level and hardware level.

[0044] At least one fault to be injected is provided through a fault injection device and injected into the intelligent driving controller of the intelligent driving function operation device. The algorithm integrated in the internal chip of the intelligent driving controller performs planning and decision-making, and outputs a safety test result. The safety test result is used to control the operation of the vehicle used for safety testing, forming a functional closed loop; and the fault monitoring device monitors the response of the intelligent driving controller to the fault to be injected, and transmits it to the user in an intuitive manner, thereby completing the safety test of the intelligent driving function.

[0045] The fault injection device includes different fault types, basically covering all faults involved in intelligent driving functions, and all have operable fault injection interfaces and implementation methods.

[0046] The faults to be injected include the main power supply and the short-circuit control faults of each controller. Such faults are connected to the intelligent driving function operation device through the power cord and its connectors for fault injection. It should be noted that the controller hardware involved in this test system has a unified power supply source; all controller hardware is located in the control cabinet of the intelligent driving function operation device, and the control cabinet is equipped with an operable disconnect and short-circuit interface. Therefore, the power disconnection and short-circuit control of all controller hardware can be easily achieved. The control block cabinet of the intelligent driving function operation device will be described in detail below.

[0047] The faults to be injected also include faults of the simulated fault signal injection control type, which are connected to the intelligent driving function operation device through various buses (including CAN, Lin, FlexRay, etc.) for fault injection. When the intelligent driving function associated system fails, a corresponding fault signal will be sent to the intelligent driving function test system to characterize its fault state. Therefore, the interface can simulate the sending of corresponding fault signals through CANOE devices or other bus devices to reproduce various fault states of the associated system.

[0048] The faults to be injected also include faults caused by poor wiring harness contact control, which are connected to the intelligent driving function operation device through wiring harness replacement or abnormal connection for fault injection. This method can replicate the faults caused by loose wiring harness, poor contact, interface wear and other problems related to the intelligent driving function caused by long-term use or other factors in the real car environment.

[0049] The faults to be injected also include chassis dynamics fault control faults, which are connected to the intelligent driving function operation device by inputting parameters for fault injection. Chassis domain dynamics control is implemented by dynamics simulation software, so chassis dynamics related faults can be created by modifying relevant parameters in the dynamics simulation software, such as modifying the motor parameters in the power steering system to simulate the failure of the power steering system.

[0050] The faults to be injected also include faults in dangerous boundary scene construction, which are injected by building scenes in simulation software and transmitting corresponding data to the intelligent driving function operation device. Specifically, some fault scenarios caused by extreme environments can be simulated, such as severe weather such as heavy rain, hail, and sandstorms, which can cause visual obstruction and other faults in the intelligent driving camera sensor.

[0051] The faults to be injected also include intelligent driving controller reliability replacement faults, which are injected by hardware replacement or environmental changes. The safety test system in this manual includes the intelligent driving controller hardware, and the controller hardware faults are verified by changing the placement environment of the controller hardware. For example, the controller hardware can be installed in a high temperature or high cold environment container to reproduce the faults in the corresponding environment; if the durability of the controller hardware needs to be verified, it can be directly replaced with old parts.

[0052] The faults to be injected also include other controller hardware reliability replacement faults, which are implemented by hardware replacement or environment change. Other controller hardware connected to the safety test system in this specification verifies the fault of the controller hardware itself by changing the placement environment of the controller hardware.

[0053] In this embodiment, compared with the existing simulation tests for basic functions of intelligent driving that aim to improve test efficiency and reduce test costs, the fault injection device of this specification can simulate more than seven types of faults, including power supply faults, hardware faults, bus faults, scenario faults, etc., basically covering all faults involved in intelligent driving functions. It is operational and repeatable, and solves the problem that it is difficult to conduct fault safety tests on real vehicles.

[0054] like Figure 2 As shown, the intelligent driving function operation device includes a control cabinet 20 connected to the fault injection device and the intelligent driving controller respectively. The control cabinet 20 is the most important component of the entire intelligent driving function operation device. It is used to connect the control cabinet and the intelligent driving controller hardware through various buses according to the fault to be injected, so as to complete various information interactions with the controller hardware and control the intelligent driving controller to perform safety tests on the vehicle.

[0055] In some embodiments, the control cabinet includes a real-time simulator, which is connected to the intelligent driving controller and is used to generate a whole vehicle simulation model. The whole vehicle simulation model provides a complete virtual environment for the controller hardware-in-the-loop test system, and the I / O signals and CAN signals corresponding to the intelligent driving controller are matched through hardware boards to achieve seamless connection between the whole vehicle simulation model and the input and output signals of the intelligent driving controller, thereby forming a closed-loop test environment. Specifically, the whole vehicle simulation model is connected to the intelligent driving controller, and the equipment in the control cabinet generates fault injection signals through simulation or real vehicle simulation, and these signals are input to the intelligent driving controller. After the intelligent driving controller performs calculations and decisions according to the internal algorithm, the instructions are sent back to the whole vehicle simulation model of the control cabinet through the bus to form a closed-loop test.

[0056] The control cabinet also includes a power supply control device 21, which is used to control the power supply and power switch of all controller hardware in the safety test system. As an example, the power supply control device includes a short-circuit test box, and the open circuit test box is configured with an operable open circuit interface and a short circuit interface, that is, a first fault injection interface, which is connected to the fault injection device through the first fault injection interface, and is used to inject the main power supply and each controller open circuit control type fault into the intelligent driving controller through the power cord and its connector, and control the intelligent driving controller to perform safety testing on the vehicle.

[0057] The control cabinet also includes a signal control device 22 for receiving and sending all bus signals in the safety test system. As an example, the signal control device includes a second fault injection interface, which is connected to the fault injection device, and is used to inject simulated fault signals into the control-type fault injection intelligent driving controller through various buses, and control the intelligent driving controller to perform safety tests on the vehicle. Exemplarily, the signal control device includes a signal conditioner, a power amplifier, a signal amplifier, a voltage-current converter, a signal collector, and the like.

[0058] The control cabinet also includes a harness interface device 23, which is used to provide a connection for the main harness in the safety test system through a connector. As an example, the harness interface device includes a third fault injection interface, which is connected to the fault injection device, and is used to inject a fault of poor harness contact control into the intelligent driving controller by replacing the harness or abnormal connection, and control the intelligent driving controller to perform safety testing on the vehicle.

[0059] The control cabinet is the most important component of the entire intelligent driving control device. In addition to providing an integrated environment for software and hardware, it can also perform unified scheduling and control of all integrated devices through control software.

[0060] The intelligent driving function operation device also includes a workstation cabinet 24, which is connected to the control cabinet via Ethernet. The workstation cabinet is mainly responsible for the integration of the workstation and the information processing and transmission of various software.

[0061] The workstation cabinet includes an electronic device that integrates at least one simulation software. The electronic device is connected to the workstation cabinet via Ethernet and is used to build a whole vehicle simulation model that interacts with the intelligent driving controller for information, and controls the operation of the vehicle based on the safety test results output by the whole vehicle simulation model and the intelligent driving controller.

[0062] In some embodiments, the workstation cabinet includes a dynamics software terminal 25. The terminal described herein represents a personal computer with a processor, a network interface, a memory, etc., and a dynamics software (exemplarily, the dynamics software uses mature commercial software, such as carsim, carmaker, etc.) is running inside the terminal, which is used to build a vehicle dynamics simulation model according to the dynamics software. As an example, the dynamics software terminal includes a fourth fault injection interface, which is connected to the fault injection device, and is used to inject the chassis dynamics fault control class fault into the intelligent driving controller by modifying the relevant parameters in the dynamics simulation software, and control the intelligent driving controller to perform safety testing on the vehicle.

[0063] The workstation cabinet also includes a scenario simulation software terminal 26. The terminal described herein represents a personal computer with a processor, a network interface, a memory, etc., and a scenario simulation software is running inside it (exemplarily, the scenario simulation software uses mature commercial software, such as VTD, PreScan, etc., which is used to provide scene images and convert them into video streams to the intelligent driving controller), which is used to build a dangerous boundary scenario simulation model according to the scenario simulation software. As an example, the scenario simulation software terminal includes a fifth fault injection interface, which is connected to the fault injection device, and is used to transmit the data of the dangerous boundary scene built in the simulation software to the intelligent driving controller to inject a fault of the dangerous boundary scene construction class, and control the intelligent driving controller to perform a safety test on the vehicle.

[0064] The workstation cabinet also includes an automated test software terminal 27. The terminal described herein represents a personal computer with a processor, a network interface, a memory, etc., and an automated test software is running inside it (exemplarily, the automated test software uses mature commercial software, such as ECUTest, etc.), which is used to run automated test cases according to the automated test software. As an example, the automated test software terminal includes a sixth fault injection interface, which is connected to the fault injection device, and is used to control the intelligent driving controller to perform automated safety testing on the vehicle by importing the automated test case into the automated test software.

[0065] The workstation described in this article and various software in the terminal are connected via Ethernet.

[0066] The intelligent driving function operation device also includes the intelligent driving controller 28, which is used for fault injection testing of the safety of the intelligent driving function, wherein the intelligent driving controller may also include multiple controller hardware as a system. As an example, the intelligent driving controller includes a seventh fault injection interface, which is connected to the fault injection device, and is used to inject a fault of the reliability replacement class of the intelligent driving controller into the intelligent driving controller according to the method of hardware replacement or environmental change, and control the intelligent driving controller to perform safety testing on the vehicle.

[0067] The intelligent driving function operation device also includes other controller hardware 29, that is, controller hardware connected to the intelligent driving controller that does not require simulation. Among them, other controller hardware is connected to the intelligent driving controller using the original connection method. As an example, the intelligent driving controller includes an eighth fault injection interface, which is connected to the fault injection device, and is used to inject the reliability replacement class fault of the intelligent driving controller into the intelligent driving controller according to the method of hardware replacement or environmental change, and control the intelligent driving controller to perform safety testing on the vehicle.

[0068] In this embodiment, an intelligent driving function operation device that can realize functional closed-loop operation is provided. In addition to realizing the simulated operation of the intelligent driving function, the device also provides various fault injection interface methods, solving the technical problem that fault injection requires the intelligent driving function to respond in a closed loop.

[0069] At present, the simulation realization of intelligent driving functions only considers the functional closed loop, but does not consider the open interface. The intelligent driving function operation device provided in this specification provides multiple fault injection interfaces and multiple fault monitoring interfaces. While realizing the functional closed loop, it can also interact with external devices. As an example, the intelligent driving controller includes at least one fault monitoring interface.

[0070] The fault monitoring device includes monitoring methods for different fault responses, which are intuitive and operational, and some of them can be automated, solving the technical problems of monitoring fault responses of intelligent driving functions.

[0071] In some embodiments, the fault monitoring device includes a central control display, which is connected to the first fault monitoring interface of the intelligent driving controller by a hardware harness, and is used to control the central control display to monitor the intelligent driving controller's response to the fault to be injected according to the safety test result output through the first fault monitoring interface. That is, through the central control display monitoring method, an external central control display is used to monitor the intelligent driving's response to the fault injection, such as an alarm text reminder, an alarm image reminder, etc.

[0072] The fault monitoring device also includes an instrument display, which is connected to the second fault monitoring interface of the intelligent driving controller by a hardware harness, and is used to control the instrument display to monitor the intelligent driving controller's response to the fault to be injected according to the safety test result output through the second fault monitoring interface. That is, through the instrument display monitoring method, an external instrument display is used to monitor the intelligent driving's response to the fault injection, such as alarm text reminder, alarm image reminder, etc.

[0073] The fault monitoring device also includes a head-up display, which is connected to the third fault monitoring interface of the intelligent driving controller by a hardware harness, and is used to control the head-up display to monitor the intelligent driving controller's response to the fault to be injected according to the safety test result output through the third fault monitoring interface. That is, through the head-up display monitoring method, an external head-up display is used to monitor the response of the intelligent driving to the fault injection, such as an alarm text reminder, an alarm image reminder, etc.

[0074] The fault monitoring device also includes a steering wheel, which is connected to the fourth fault monitoring interface of the intelligent driving controller by a hardware harness, and is used to control the steering wheel to monitor the response of the intelligent driving controller to the fault to be injected according to the safety test result output through the fourth fault monitoring interface. That is, by means of steering wheel vibration monitoring, an external steering wheel is used to monitor the response of the intelligent driving to the fault injection, such as steering wheel vibration reminder, etc.

[0075] The fault monitoring device also includes an alarm, which is connected to the fifth fault monitoring interface of the intelligent driving controller by a hardware harness, and is used to control the steering wheel to monitor the intelligent driving controller's response to the fault to be injected according to the safety test result output through the fifth fault monitoring interface. That is, by means of alarm vibration monitoring, an external alarm is used to monitor the response of the intelligent driving to the fault injection, such as an alarm sound reminder, etc.

[0076] The fault monitoring device also includes a scene simulation software monitoring method in the scene simulation software terminal, which is connected to the sixth fault monitoring interface of the intelligent driving controller and displayed through the scene simulation software. That is, for the response of intelligent driving to the fault, by observing the simulated vehicle performance in the scene simulation software, it is judged whether its response method is reasonable. For example, for the fault scenario where the intelligent driving function cannot be used normally in bad weather, it can be observed whether the vehicle in the scene software can smoothly exit the function and park safely, etc.

[0077] The fault monitoring device also includes an automated test software monitoring method in the automated test software terminal, which is connected to the seventh fault monitoring interface of the intelligent driving controller and displayed through the scene simulation software. That is, the response of the intelligent driving to the fault can be realized by logical verification of the relevant signals, and a test case is formed for automated verification, that is, the condition for the occurrence of the fault is used as the execution step of the case, and the fault response feedback information of the intelligent driving is used as the judgment condition for whether the case passes or not, so that the intelligent driving fault response can be automatically monitored.

[0078] In this embodiment, compared with the current observation of simulation test results, which is mainly presented through scenario simulation software and use case test results, the response of intelligent driving to faults in this application is more directly conveyed to the driver, such as literary prompts, alarm sound prompts, steering wheel vibration prompts, etc. The fault monitoring device provided by this application includes at least seven fault monitoring methods, which basically cover all forms of display of intelligent driving responses to faults, and are all intuitive and operable.
