Description

Technical Field

[0001] This invention relates to the field of autonomous driving control, and more particularly to a method, apparatus, device, and storage medium for displaying vehicle faults. Background Technology

[0002] In recent years, with the rapid development of autonomous driving technology, related vehicles have achieved different levels of autonomous driving functions by relying on artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems. Since vehicles at different levels of autonomous driving may experience some autonomous driving-related malfunctions during the testing and operation phase, and some functions of the test vehicles still need debugging and verification, in order to ensure the safety of driving test personnel in their daily driving, it is necessary to promptly display, display, take over, and handle relevant prompts and processing information for test personnel to perform takeover operations. This reduces the safety risks caused by malfunctions in autonomous driving test vehicles and protects the safety of test personnel and test vehicles during the measurement and testing process.

[0003] Currently, testers determine whether a vehicle needs to be taken over by relying on safety officers to display warning lights on the instrument panel, combined with the surrounding environment. However, with an increasing number of faults requiring diagnosis and display, the available hardware space for warning lights on the instrument panel is decreasing. This method directly leads to some warning lights failing to display or requiring alternative methods for timely display. Combined with the time allotted for safety officers' self-assessment, this results in delays in prompting safety personnel to take over safely. In other words, existing autonomous vehicles offer poor timely warnings regarding relevant faults during testing. Summary of the Invention

[0028] This invention provides a method, apparatus, device, and storage medium for displaying vehicle faults. The method includes: acquiring driving control commands from a target vehicle and generating system interaction commands between the autonomous driving system and the vehicle communication system in the target vehicle; based on the results of the system interaction calls, performing responsiveness detection on the driving test functions to obtain detection results, and determining the fault level corresponding to the target vehicle based on the correlation between the detection results and the interaction of the driving test functions; generating a fault display command corresponding to the target vehicle according to a preset fault safety level based on the fault level, and generating fault display information corresponding to the target vehicle based on the fault display command. This application enables timely display of different system faults during the testing of autonomous vehicles.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein.

[0030] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the method for displaying vehicle faults in this invention includes:

[0031] 101. Obtain the driving control commands of the target vehicle, and based on the driving control commands, perform system interaction calls for the preset driving test functions of the target vehicle;

[0032] The embodiments of this application can acquire and process relevant data based on artificial intelligence technology. Artificial intelligence (AI) refers to the theories, methods, technologies, and application systems that use digital computers or machines controlled by digital computers to simulate, extend, and expand human intelligence, perceive the environment, acquire knowledge, and use that knowledge to obtain optimal results.

[0033] Foundational technologies for artificial intelligence generally include sensors, dedicated AI chips, cloud computing, distributed storage, big data processing, operating / interactive systems, and mechatronics. AI software technologies mainly encompass computer vision, robotics, biometrics, speech processing, natural language processing, and machine learning / deep learning.

[0034] In this embodiment, the driving control commands refer to the relevant control commands generated by the autonomous driving system during road testing to control the vehicle to perform autonomous driving. The system interaction call refers to the need for communication and assistance between the on-board control system and various communication systems in the target vehicle to complete the corresponding driving control and achieve the corresponding autonomous driving function. In addition, the interaction objects in this application include the first interaction object (i.e., the autonomous driving system) and the first interaction object (i.e., the communication system). Other systems can be added or deleted according to the needs of the interaction. The autonomous driving system (i.e., the first interaction object) refers to the autonomous driving control system, including the original control system (steering EPS, braking ESC, power ECU, body BMC) and the intelligent driving control system (MU computing unit, RU unit, CDB module and sensor kit). The communication system (i.e., the second interaction object) refers to the system used for communication and information exchange within or between vehicles. It mainly realizes data transmission and communication between various modules inside the vehicle and between the vehicle and external systems through internal networks, sensors and wireless communication technologies, such as internal communication systems, communication systems between the vehicle and the driver, communication systems between the vehicle and external systems, and inter-vehicle communication systems.

[0035] In practical applications, relevant driving control commands of the target vehicle are obtained, and then based on the driving control commands, system interaction commands are generated between the autonomous driving system (i.e., the first interaction object) and various subsystems in the vehicle communication system (i.e., the second interaction object) of the target vehicle.

[0036] 102. Based on the results of system interaction calls, the responsiveness of the driving test function is tested to obtain the test results. Based on the test results and the interaction correlation of the driving test function, the fault level corresponding to the target vehicle is determined.

[0037] In this embodiment, the responsiveness detection of the interactive function refers to the detection of the responsiveness of the interactive function between the systems by detecting whether the corresponding subsystems have completed the corresponding operation and by detecting the corresponding operation feedback instructions in order to complete the corresponding driving function. The interaction correlation refers to the interrelationship between the subsystems in completing the corresponding driving function.

[0038] In practical applications, multiple interactive objects corresponding to the completion of the driving test function are identified, as well as the communication and interaction relationships between these objects. Based on the results of system interaction calls, functional detection instructions corresponding to each interactive object are generated according to the communication and interaction relationships. The functional detection instructions are then used to perform responsiveness detection on each interactive object to obtain the detection results. Based on the detection results, the driving status information of the target vehicle during detection and the interaction status information between each interactive object are determined. This allows for the combination of interaction fault states between subsystems based on the driving status information and interaction status information. Based on the results of the state combination, the fault levels between different interactive subsystems are generated.

[0039] 103. Based on the fault level, generate the fault display command corresponding to the target vehicle according to the preset fault safety level, and generate the fault display information corresponding to the target vehicle based on the fault display command.

[0040] In this embodiment, the fault safety level refers to the safety zone level set for different driving faults, so as to quickly take corresponding safety control measures; the display control module refers to the module that completes the corresponding display function (such as the central control screen, warning LEDs, mobile devices connected to the vehicle system, etc.).

[0041] In practical applications, if the fault level is the first fault level, the driving status information is determined to be in an autonomous driving state, and the first or second interactive object is determined to correspond to a single interactive fault object. Then, based on the interactive fault object, according to the preset fault safety level, the remote control mode and takeover operation command of the first interactive object are matched. Based on the remote control mode and takeover operation command, the first fault display command of the target vehicle is generated, and based on the fault display command, the corresponding fault display information of the target vehicle is generated.

[0042] If the fault level is the second fault level, the driving status information is determined to be the driving start state, and at least one interactive fault object between the first interactive object and / or the second interactive object is determined; then, based on the driving start state and the interactive fault object, the mode switching command and takeover operation command of the second interactive object are matched according to the preset fault safety level; thereby, based on the mode switching command and takeover operation command, the first fault display command of the target vehicle is generated, and based on the fault display command, the corresponding fault display information of the target vehicle is generated.

[0043] If the fault level is the third fault level, determine the test interaction object between the first interaction object and / or the second interaction object; then, based on the test interaction object and driving status information, match the target vehicle's autonomous driving mode and automatic operation command; thereby, based on the autonomous driving mode and automatic operation command, generate the target vehicle's third fault display command.

[0044] Furthermore, the fault display logic corresponding to the fault level of the target vehicle is determined, and based on the fault display logic, fault display objects corresponding to the fault display states are selected sequentially; thereby, fault display instructions are used to control the fault display objects to generate fault display information corresponding to the vehicle's detection state. The fault levels include a first fault level, a second fault level, and a third fault level, and the fault display instructions include a first fault display instruction, a second fault display instruction, and a third fault display instruction.

[0045] In this embodiment of the invention, driving control commands from the target vehicle are acquired, and based on these commands, system interaction calls for preset driving test functions are made to the target vehicle. Based on the results of these system interaction calls, the responsiveness of the driving test functions is tested to obtain the test results. Based on the correlation between the test results and the interaction of the driving test functions, the corresponding fault level of the target vehicle is determined. Based on the fault level, a fault display command corresponding to the target vehicle is generated according to a preset fault safety level, and based on the fault display command, fault display information corresponding to the target vehicle is generated. Compared to existing technologies, this application uses driving control commands to generate system interaction commands between the autonomous driving system and the vehicle communication system. Then, based on these system interaction commands, interaction function tests are performed on various subsystems to determine the corresponding fault level of the target vehicle. Based on the fault level, a corresponding display control module is selected, thereby controlling the display control module to generate fault display information for the corresponding faulty subsystem. This enables timely display of different system faults during the testing process of the autonomous vehicle.

[0046] Please see Figure 2 A second embodiment of the method for displaying vehicle faults in this invention includes:

[0047] 201. Obtain the driving control commands of the target vehicle, and based on the driving control commands, perform system interaction calls for the preset driving test functions of the target vehicle;

[0048] 202. Determine the multiple interactive objects corresponding to the completion of the driving test function, as well as the communication and interaction relationships between each interactive object;

[0049] In this embodiment, the communication interaction relationship refers to the corresponding communication connection relationship between various subsystems. For example, the steering EPS, braking ESC, power ECU, body BMC, and CDB module are connected via a CAN bus; the steering EPS, braking ESC, power ECU, and body BMC can also be connected via the electronic parking brake controller area network (EPB_CAN); the MU computing unit and RU unit are connected via the body electronic system controller area network (Body_CAN); and the CDB module and sensor kit are connected to each other via the power controller area network (Power_CAN). The interaction objects here include the autonomous driving system and the vehicle communication system, and the various subsystems contained within these two systems.

[0050] In practical applications, the communication and interaction relationships between various subsystems related to the autonomous driving system and the vehicle communication system and various system interaction commands are determined, as well as the communication and interaction relationships between the various subsystems corresponding to the completion of various system interaction commands (i.e., when corresponding to driving control functions).

[0051] 203. Based on the results of system interaction calls, generate corresponding function detection instructions between each interaction object according to the communication interaction relationship;

[0052] In this embodiment, based on the results of the current system interaction calls of the target vehicle, sub-detection instructions between subsystems required to complete the corresponding driving control function are generated according to the communication interaction relationship between each subsystem.

[0053] 204. Use functional testing instructions to perform responsiveness testing on each interactive object and obtain the test results;

[0054] In this embodiment, the various sub-detection instructions described above are used to perform system function detection of the corresponding driving control functions of each subsystem (i.e., various interactive objects), and the feedback instruction information of the system function detection is collected to generate detection results.

[0055] 205. Based on the detection results, determine the driving status information of the target vehicle during detection, and determine the interaction status information between each interactive object;

[0056] In this embodiment, the driving status information refers to the current driving status of the vehicle when the corresponding autonomous driving function is completed (such as whether it is completed, the degree of completion, etc.).

[0057] In practical applications, based on various feedback instruction information in the detection results, the driving status of the target vehicle during road test autonomous driving is determined, as well as the status information of whether the corresponding subsystems have completed the corresponding instruction interaction when each subsystem between the autonomous driving system and the vehicle communication system completes the corresponding driving control function.

[0058] 206. Combine the driving status information and interaction status information into corresponding interaction fault states, and generate fault levels between different interaction subsystems based on the results of the state combination.

[0059] In this embodiment, the driving status information and interaction status information are combined into different states of subsystem interaction faults. Based on the different combinations of the two states, the corresponding fault levels between different interaction subsystems are generated according to a preset combination level table.

[0060] 207. Determine the fault display logic corresponding to the fault level of the target vehicle, and select the fault display objects corresponding to the fault display status in sequence based on the fault display logic;

[0061] In this embodiment, based on the fault level, a fault display command corresponding to the target vehicle is generated according to a preset fault safety level. This determines the fault display logic for the target vehicle's corresponding fault level. For example, a solid red light, off yellow light, and off green light indicate a vehicle-side fault (including red button activation) and a system fault, preventing entry into automatic mode. The safety driver is reminded to manually drive, inspect the vehicle, or request an ambulance. A solid red light, off yellow light, and flashing green light indicate a vehicle-side fault (including red button activation) but a normal system, preventing entry into automatic mode. The safety driver is reminded to manually drive, inspect the vehicle, or request an ambulance. An off red light, solid yellow light, and flashing green light indicate that the automatic driving system and vehicle are in place and automatic mode can be activated. An off red light, solid yellow light, and solid green light indicate that automatic mode has been successfully entered. An off red light indicates that automatic mode has been successfully entered. The system may display various LED lights, such as flashing yellow lights and a solid green light, indicating a transition from automatic to remote control mode. A flashing red light, a non-lit yellow light, and a solid green light indicate a system malfunction during automatic driving but the system has not yet exited, prompting the safety operator to take over (simultaneously, the system is handling malfunctions, such as braking). A flashing red light, flashing yellow light, flashing green light, and a buzzer sound indicate a vehicle-side malfunction or communication interruption, requiring an emergency braking attempt to exit automatic mode and prompting the safety operator to take over. The LED lights must be matched with the corresponding display control module. The LED lighting state is controlled by the control module; changes in the displayed content generate control data commands that are transmitted to the control module's drive circuit, dynamically illuminating the LEDs. The display based on the LED lighting pattern is only used to explain the invention and is not intended to limit the invention. Based on the fault display logic, the corresponding display control module, such as a digital display screen, LED light display, or buzzer, is selected sequentially according to the fault display state. Furthermore, commands based on the automatic driving control system can be executed within the device to display digital lights and flashing, LED lights and flashing, and a buzzer warning.

[0062] 208. Using fault display commands, control the fault display object to generate fault display information corresponding to the vehicle detection status.

[0063] In this embodiment, the aforementioned fault display command is used to control the corresponding display control module to generate fault display information for the corresponding vehicle detection status, so as to prompt the test personnel to take corresponding actions in a timely manner and control the test vehicle to perform automatic adjustment control for the corresponding fault.

[0064] In this embodiment of the invention, driving control commands are used to generate system interaction commands between the autonomous driving system and the vehicle communication system. Based on these commands, interaction functions of various subsystems are detected to determine the fault level of the target vehicle. Then, based on the fault level, a corresponding display control module is selected, which generates fault display information for the corresponding faulty subsystem. This enables timely display of different system faults during the testing process of the autonomous vehicle.

[0065] Please see Figure 3 A third embodiment of the method for displaying vehicle faults in this invention includes:

[0066] 301. Obtain the driving control commands of the target vehicle, and based on the driving control commands, perform system interaction calls for the preset driving test functions of the target vehicle;

[0067] 302. Based on the results of system interaction calls, the responsiveness of the interactive function of the driving test function is tested to obtain the test results. Based on the test results and the interaction correlation of the driving test function, the fault level corresponding to the target vehicle is determined.

[0068] 303. If the fault level is the first fault level, determine that the driving status information is in the automatic driving state, and determine that the first interaction object or the second interaction object corresponds to a single interaction fault object.

[0069] In this embodiment, if the fault level is the first fault level, the driving status information is determined to be in an autonomous driving state, and the first or second interaction object is determined to correspond to a single interaction fault object.

[0070] 304. Based on the interactive fault object, match the remote control mode and takeover operation instructions of the first interactive object according to the preset fault safety level;

[0071] In this embodiment, based on the sub-fault system, the remote control mode and takeover operation command corresponding to the autonomous driving system are matched according to the preset fault safety level.

[0072] 305. Based on the remote control mode and takeover operation command, generate the first fault display command for the target vehicle;

[0073] In this embodiment, based on the aforementioned remote control mode and takeover operation command, a first fault display command for the target vehicle is generated. For example, if the autonomous driving system of the autonomous vehicle malfunctions, a fault display command is generated based on the fault level of the autonomous driving read command. The fault display command generates a control command to make the display device flash (transitioning from autonomous driving mode to remote control mode, reminding the safety operator to prepare for manual takeover). Alternatively, if the vehicle communication of the autonomous vehicle is interrupted, a fault display command is generated based on the fault level of the autonomous driving read command. The fault display command generates a control command to make the display device flash, and simultaneously generates a warning command to trigger a buzzer alarm.

[0074] 306. If the fault level is the second fault level, determine that the driving status information is the driving start state, and determine at least one interactive fault object between the first interactive object and / or the second interactive object.

[0075] In this embodiment, if the fault level is the second fault level, the driving status information of the current target vehicle is determined to be the driving start state, and at least one interactive fault object between the first interactive object and / or the second interactive object is determined.

[0076] 307. Based on the driving start status and the interactive fault object, match the mode switching command and takeover operation command of the second interactive object according to the preset fault safety level;

[0077] In this embodiment, based on the driving start state and the interactive fault object, the mode switching command and takeover operation command of the second interactive object are matched according to the preset fault safety level.

[0078] 308. Based on the mode switching command and the takeover operation command, generate a second fault display command for the target vehicle;

[0079] In this embodiment, a second fault display instruction for the target vehicle is generated based on the aforementioned mode switching instruction and takeover operation instruction. For example, if a vehicle communication failure occurs while the vehicle is running (including emergency stop button press and device malfunction), but the autonomous driving system is functioning normally, a fault display instruction is generated based on the fault level determined by the autonomous driving read instruction. This fault display instruction generates a control instruction to illuminate the display device. Entering autonomous driving mode is not supported. Additionally, auxiliary operation information is generated to remind the safety driver to manually drive, indicating a vehicle malfunction requiring inspection or assistance with an ambulance. Alternatively, if multiple communication failures occur between the autonomous driving system and the vehicle while the vehicle is running (including emergency stop button press and device malfunction), a fault display instruction is generated based on the fault level determined by the autonomous driving read instruction. This fault display instruction generates a control instruction to illuminate the display device. Entering autonomous driving mode is not supported. Additionally, auxiliary operation information is generated to remind the safety driver to manually drive, indicating a vehicle malfunction requiring inspection or assistance with an ambulance.

[0080] 309. If the fault level is the third fault level, determine the test interaction object between the first interaction object and / or the second interaction object;

[0081] In this embodiment, if the fault level is the third fault level (where the third fault level here is the normal driving state), the test interaction object between the first interaction object and / or the second interaction object is determined.

[0082] 310. Based on the test interaction object and driving status information, match the target vehicle's autonomous driving mode and automatic operation commands;

[0083] In this embodiment, based on the test interaction object and driving status information, the autonomous driving mode and automatic operation instructions for the target vehicle to continue autonomous driving control during the road test are matched.

[0084] 311. Based on the automatic driving mode and automatic operation instructions, generate a third fault display instruction for the target vehicle;

[0085] In this embodiment, a third fault display instruction for the target vehicle is generated based on the aforementioned autonomous driving mode and automatic operation instructions. If the vehicle is running and both the autonomous driving system and the vehicle system are functioning normally, a display instruction is generated based on the autonomous driving read instruction level.
