And in the following embodiments, each embodiment is described with its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0031] For the method steps described in the embodiments of the present utility model, the execution order can be the order described in the specific embodiments, or can be adjusted according to actual needs on the premise of being able to solve the technical problems. The execution order of each step is not listed one by one here.

[0032] Referring to Figure 1 , a data acquisition system includes an acquisition trigger button 1, a data acquisition host 2, and a data acquisition terminal.

[0033] The acquisition trigger button 1 is used to generate a trigger signal based on user operations. The acquisition trigger button 1 can be a physical button set in the vehicle cockpit. When the driver encounters an abnormality in the intelligent driving function, pressing this button can generate a trigger signal. This button can be designed in a form that is easy to operate and locate, such as being installed on the steering wheel or next to the driver's seat. When the driver or tester presses the button, the system will recognize this operation and generate a corresponding trigger signal, thereby starting the data acquisition process and recording relevant data such as vehicle cameras, perception, path planning and control, and positioning for subsequent analysis and processing.

[0034] The data acquisition host 2 is electrically connected to the acquisition trigger button 1 and generates a data acquisition signal in response to the trigger signal. The data acquisition host 2 can be an embedded system, such as a single-board computer or an embedded development board based on the ARM architecture; an intelligent edge device can also be selected, which has strong processing capabilities and intelligent algorithm support; a cloud server is also an option for large-scale data processing and storage; in addition, for specific application scenarios, a customized hardware platform can also be selected to meet specific requirements. It should be noted that the processing logic of generating a data acquisition signal in response to a trigger signal is a common practice in the prior art. This process is usually implemented in the control logic of the data acquisition system. When the system receives an indication from the trigger signal, it will perform corresponding operations to generate a data acquisition signal to start the data acquisition process. This process can include starting the data acquisition device, setting acquisition parameters, recording the acquisition time, etc. Therefore, this operation of generating a data acquisition signal in response to a trigger signal is common in the prior art and is widely used in various data acquisition systems.

[0035] The data acquisition terminal is data-connected to the data acquisition host 2 and performs data acquisition in response to the data acquisition signal. Specifically, the data acquisition terminal can be an in-vehicle device that is connected to the data acquisition host 2 through a data connection. When it receives the data acquisition signal from the data acquisition host 2, it starts to perform data acquisition. For example, this in-vehicle device can include an external camera 5, and when it receives a signal, the camera starts recording the vehicle's driving situation or other specific scenarios. At the same time, the data acquisition terminal can also include other sensors for collecting various state information of the vehicle, such as vehicle speed, steering angle, acceleration, etc. In this way, the data acquisition terminal can respond to the data acquisition signal and start collecting the required data.

[0036] By collecting the trigger button 1, the data acquisition host 2, and the data acquisition terminal, the automatic acquisition of vehicle - end data can be achieved. First, a trigger button 1 is set inside the vehicle. When the driver encounters an abnormality in the intelligent driving function or needs to collect data, pressing this button can generate a trigger signal. This trigger signal is transmitted to the data acquisition host 2, triggering the host to generate a data acquisition signal. The data acquisition signal is transmitted to the data acquisition terminal to initiate the data acquisition process. The data acquisition terminal can include devices such as an external camera 5 and sensors, which are used to collect various vehicle - end data. For example, the camera can record videos inside or outside the vehicle, and the sensors can collect the vehicle's status information. In this way, through the coordinated action of the trigger button 1, the data acquisition host 2, and the data acquisition terminal, the automatic acquisition of vehicle - end data is realized, improving the efficiency and accuracy of data acquisition.

[0037] Further, as a specific embodiment of the present utility model, the data acquisition terminal includes an external camera 5, and the external camera 5 responds to the data acquisition signal to perform vehicle - end display screen recording.

[0038] Specifically, the external camera 5 is installed inside the vehicle and is connected to the data acquisition host 2 through a data connection. When the external camera 5 receives the data acquisition signal from the data acquisition host 2, it is triggered to record. By recording the video displayed on the vehicle - end display screen with the external camera 5, the display problems of the instrument large - screen can be more clearly checked when using the collected data for subsequent fault analysis.

[0039] Furthermore, as a specific embodiment of the present utility model, the external camera 5 at least includes a first camera, a second camera, and a third camera;

[0040] The first camera is used to record the vehicle - end display screen;

[0041] The second camera is used to record the driver's operations;

[0042] The third camera is used for the road scene outside the vehicle.

[0043] Specifically, multiple external cameras 5 can be set up and installed inside or outside the vehicle respectively, and are connected to the data acquisition host 2 through data connection. When the external camera 5 receives a data acquisition signal, it starts recording videos inside and / or outside the vehicle. For example, the first camera can be installed at the position of the rearview mirror for recording the vehicle-end display screen. The second camera can be installed above the driver's seat inside the vehicle to record the driver's operations; at the same time, a third camera can also be installed outside the vehicle to record the roads, traffic conditions and pedestrian behaviors around the vehicle. In this way, by responding to the data acquisition signal for video recording, the automatic acquisition of the situation inside and / or outside the vehicle is realized, providing important support for subsequent data analysis and driving behavior evaluation.

[0044] Furthermore, as a specific embodiment of the present invention, the data acquisition terminal further includes an intelligent driving data collector 3, and the intelligent driving data collector 3 responds to the data acquisition signal to collect on-vehicle intelligent driving data.

[0045] In specific implementation, the data acquisition terminal may include an intelligent driving data collector 3. When the intelligent driving data collector 3 receives a data acquisition signal, it starts collecting on-vehicle intelligent driving data. The intelligent driving data collector 3 is used to record relevant intelligent driving data such as vehicle cameras, perception, path planning and control, positioning, and maps. The intelligent driving data collector 3 can directly utilize existing devices on the vehicle such as sensors, camera systems, radars, navigation systems, and vehicle control units to implement the function of collecting intelligent driving data without the need to install new devices additionally. These devices can provide data such as the dynamic information of the vehicle, the perception of the surrounding environment, the vehicle position and status, providing necessary data support for the research and development and testing of the intelligent driving system. By responding to the data acquisition signal for intelligent driving data collection, the automatic acquisition of on-vehicle intelligent driving data is realized, providing important support for the research and development and testing of the intelligent driving system.

[0046] Furthermore, as a specific embodiment of the present invention, the data acquisition terminal further includes an intelligent cabin data collector 4, and the intelligent cabin data collector 4 responds to the data acquisition signal to collect on-vehicle cabin data.

[0047] Specifically, after the driver triggers the dotting through the physical button, the intelligent cabin data collector 4 automatically records the pcap data of the vehicle-end large screen. The pcap data is a kind of log data for the intelligent cabin software, which is used for problem cause positioning when analyzing intelligent cabin-related problems. In addition, the recorded relevant log data is not limited to the pcap data related to the intelligent cabin, but can also be the log data of other associated components related to intelligent driving.

[0048] Further, as a specific embodiment of the present utility model, the data acquisition terminal further includes a microphone 6, and the microphone 6 responds to the data acquisition signal and performs sound recording within a preset duration.

[0049] The microphone 6 in the data acquisition terminal can respond to the data acquisition signal, activate the sound recording function, and record the sound information inside the vehicle. When receiving the data acquisition signal, the microphone 6 starts to record the sound within a preset duration, including the driver's voice description, the sound of the vehicle interior environment, etc. By recording the sound information, the description of the driver when encountering problems, the noise situation inside the vehicle, etc. can be recorded, providing an important basis for subsequent data analysis and problem diagnosis.

[0050] Further, as a specific embodiment of the present utility model, the data acquisition terminal further includes a speech recognizer, and the speech recognizer is data-connected to the microphone 6 and is used to convert the recorded sound into corresponding text information.

[0051] Specifically, the speech recognizer in the data acquisition terminal is connected to the microphone 6 and is used to convert the recorded sound into corresponding text information. Once the microphone 6 starts to record sound and obtains the voice information within a preset duration, the speech recognizer will process the recorded sound and convert it into recognizable text information. In this way, the problems described by the driver, the sound of the vehicle interior environment, etc. can all be automatically converted into text, providing convenience for subsequent data analysis, problem diagnosis, and recording.

[0052] Exemplarily, after the driver triggers the dotting through a physical button, the recording is automatically started for a certain duration. The driver can describe relevant problem phenomena or index data in a fixed format, and the system converts it into text through speech recognition for storage and processing. The system will also save the driver's voice, corresponding to the recorded problems.

[0053] Further, as a specific embodiment of the present utility model, the data acquisition terminal further includes an external locator 8, and the external locator 8 is used to directly collect the position information of the vehicle during testing.

[0054] Specifically, by directly installing the external locator 8 on the vehicle, the position information of the vehicle during testing can be directly obtained, thereby improving the convenience of obtaining the vehicle position information. At the same time, the position information obtained through the external locator 8 can also be used to verify and compare with the positioning information in the intelligent driving data, improving the accuracy of the vehicle position information.

[0055] Further, as a specific embodiment of the present utility model, the acquisition trigger button 1 is configured as a dotting button externally connected to the vehicle end, and the trigger signal is a dotting signal.

[0056] Specifically, the acquisition trigger button 1 is configured as a dotting button externally connected to the vehicle end, and the trigger signal it emits is called a dotting signal. When the driver presses this button, the trigger signal is the dotting signal, indicating that the data acquisition system starts to acquire data. This setting enables the driver to easily trigger the data acquisition process by pressing the button when discovering abnormal intelligent driving functions or other situations that need to be recorded, thus conveniently and quickly obtaining relevant data.

[0057] Further, as a specific embodiment of the present invention, the dotting button includes a problem dotting button and an index dotting button; the problem dotting button is used to generate a problem acquisition trigger signal, and the problem acquisition trigger signal is used to trigger the acquisition operation of intelligent driving problem data during the intelligent driving test process; the index dotting button is used to generate an index acquisition trigger signal, and the index acquisition trigger signal is used to trigger the acquisition operation of preset index data during the intelligent driving test process.

[0058] Specifically, when the user presses the problem dotting button of the trigger button, the system starts to record the intelligent driving problem data during the intelligent driving test process, such as problems of running a red light, collision risk problems, etc., records the intelligent driving related data, and records the driver's voice description to assist in problem judgment; when the user presses the index dotting button, the system starts to record the KPI index data during the intelligent driving test process, such as the number of straight / left / right turns at intersections, the number of on / off ramps, the number of navigation lane changes, the number of overtaking lane changes, etc.

[0059] Further, as another specific embodiment of the present invention, the acquisition trigger button 1 is configured as a high beam lever, a time interval paddle and / or a turn signal lever, and the trigger signal is a high beam lever signal, a time interval paddle signal and / or a turn signal.

[0060] In some other embodiments, the acquisition trigger button 1 can be configured as a high beam lever, a time interval paddle, a turn signal lever or other control devices such as other in-vehicle interaction devices on the vehicle, and the trigger signals respectively correspond to the high beam lever signal, the time interval paddle signal and / or the turn signal or other interaction device signals. When the driver operates these control devices, the system will detect the corresponding signals and trigger the data acquisition process based on these. For example, when the driver operates the high beam lever, the time interval paddle or the turn signal lever, the system will receive the corresponding signals, thereby starting data acquisition and recording the relevant intelligent driving data for subsequent analysis and processing. This setting enables the driver to trigger data acquisition through daily driving operations, improving the convenience and practicality of data acquisition.

[0061] For example, when the high beam lever signal is triggered, the driver can turn the high beam lever on the vehicle side to flash the high beam, and the system triggers the recording of vehicle-side data by monitoring the CAN signal of the high beam on the vehicle side. When the interval paddle signal is triggered, the driver can turn the interval paddle, and the system triggers the recording of vehicle-side data by monitoring the change of the paddle CAN signal. When the turn signal combination signal is triggered, the driver can turn the turn signal to the left and then turn the turn signal to the right within a certain period of time, or turn the turn signal to the right and then turn the turn signal to the left within a certain period of time, to trigger the recording of vehicle-side data.

[0062] Furthermore, as a specific embodiment of the present utility model, the system further includes a data storage device 7, and the data storage device 7 is used to store the collected data.

[0063] Specifically, after the driver triggers the marking through the physical button, the data collection system stores all relevant collected data in a folder in the specified directory in the specified format, which is convenient for subsequent data processing and problem tracing.

[0064] Furthermore, as a specific embodiment of the present invention, the system further includes a data analysis module 9, and the data analysis module 9 is used to perform statistics on the collected data and output them in a visual manner.

[0065] Specifically, the data analysis module 9 generates the coverage trajectory and test mileage of the intelligent driving test vehicle in real time based on the collected data; at the same time, the data analysis module 9 can also perform real-time statistics on the collected data, and calculate the KPI data such as the left-turn / right-turn / straight-through pass rate at the intersection, the success rate of on-ramp and off-ramp, the success rate of navigation lane change, the success rate of overtaking lane change, and the frequency of different types of intelligent driving problems per 100 kilometers by filtering the intelligent driving software version information, time period, etc.; in addition, the data analysis module 9 can generate a comparison chart of different versions of KPI data by comparing historical collected data, so that testers can intuitively judge the optimization items and return items of different intelligent driving versions. It should be pointed out that the generation of the above-mentioned coverage trajectory and test mileage, the statistics of each success rate in the KPI data, and the comparison algorithm of historical data are all existing technologies in this field and will not be repeated here.

[0066] The data acquisition system described in the utility model, when the driver finds that the intelligent driving function performs abnormally, triggers the tapping through physical buttons to automatically record the vehicle camera, perception, regulation and control, positioning, map, pcap, log and other related intelligent driving data, and records the data of multiple cameras connected to the vehicle at the same time; starts recording synchronously, and the recording duration is adjustable. The driver describes the problem phenomenon and the relevant indicator data in the intelligent driving process in a fixed voice format; the relevant data is synchronously stored in the specified directory folder.

[0067] The embodiment of the utility model also discloses a vehicle.

[0068] The vehicle is configured with the data acquisition system described in any one of the above embodiments. The vehicle is equipped with a data acquisition system having an automated data acquisition function, such as a collection trigger button 1, an external camera 5, an intelligent cabin data collector 4, a microphone 6, a voice recognizer, etc. Such a configuration enables the vehicle to automatically collect information such as intelligent driving data, in-vehicle cockpit data, and driver voice descriptions during driving, providing important support and a data basis for the development and testing of intelligent driving technologies.
