[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, the following are described:

[0023] With the rapid development of autonomous driving technology, the professional competence and emergency response level of the in-vehicle safety operator, as the last line of defense for ensuring the safe operation of the autonomous driving system, are of paramount importance. In order to train in-vehicle safety operators efficiently and accurately, an autonomous driving operation behavior collection device has emerged. This device comprehensively records the operation behavior of in-vehicle safety operators in different training scenarios through multi-sensor fusion, providing scientific basis and targeted guidance for training, which is of great significance for improving the safety and reliability of autonomous driving.

[0024] The data acquisition device can capture various operational behaviors of the safety driver in the vehicle in autonomous driving mode in real time and with high accuracy. Whether operating the autonomous driving system or performing manual takeover operations such as braking and steering, it can record them in detail. During the recording process, it can obtain not only the timestamps of the operations but also detailed data of the operations.

[0025] The massive amounts of data collected will be efficiently stored by the device. The original operational data and environmental data will be compressed and stored in a local large-capacity storage device (such as a 1TB SSD). At the same time, they will be uploaded to the cloud server in real time through communication modules such as WiFi, 4G / 5G, to achieve dual backup and long-term preservation of data.

[0026] Data collection devices play a crucial role in the skills training of safety drivers in autonomous vehicles. These devices can comprehensively collect operational behavior data of safety drivers in different training scenarios. Instructors use this data to evaluate the accuracy and standardization of the safety drivers' operation of the autonomous driving system, as well as the timeliness of their takeover, and determine whether they have the ability to safely drive autonomous vehicles.

[0027] Please refer to Figures 1-5The autonomous driving operation behavior collection device based on in-vehicle safety operator training includes a first mounting base 1, a protective pad 2, and a control component 3. A counting plate 4 is movably connected to the middle of the first mounting base 1, and a sleeve 5 is inserted into the middle of the counting plate 4. The sleeve 5 is annularly fitted onto the outer surface of the steering wheel shaft. Several anti-slip pads 12 are fixedly connected to the inner wall of the sleeve 5 by heat fusion. The anti-slip pads 12 are made of rough rubber material to increase frictional resistance, thereby ensuring that the counting plate 4 rotates synchronously with the steering wheel shaft. A second double-sided adhesive 16 is fixedly attached to the bottom end of the first mounting base 1 by bonding. The second double-sided adhesive 16 is used to stick to the vehicle body. A through groove 13 allows the steering wheel shaft to be inserted and rotated. As this is existing technology, it will not be described in detail here. The surface of the counting plate 4 has several holes and slots 6, symmetrically distributed for counting. A first slot 8 is formed in the middle of the first mounting base 1. An infrared sensor 9 is fixedly installed at the bottom of the first slot 8 to emit and receive laser signals for counting, recording data such as the time, angle, and speed at which the safety officer inside the vehicle turns the steering wheel during training. A through slot 13 is formed in the middle of the first slot 8. A second terminal 10 is inserted into the side wall of the first mounting base 1. A pressure sensor 14 is fixedly installed in the middle of the side wall of the pad 2. A first terminal 7 is coupled to the top of the pressure sensor 14. A first double-sided adhesive 15 is pasted on the side wall of the pad 2 near the pressure sensor 14. The first double-sided adhesive 15 is ring-shaped and sleeved on the outer surface of the pressure sensor 14. The first double-sided adhesive 15 is adhered to the surface of the vehicle brake pedal, improving the installation stability of the pressure sensor 14. The control component 3 includes a second mounting base 301. Several connectors 302 are inserted into the side wall of the second mounting base 301 for signal transmission. A panel 303 is snapped onto the front of the second mounting base 301. A display screen 306 is embedded in the surface of the panel 303 to display the operation instructions of the safety officer during the training process, so that the safety officer can read them in real time during the training process for convenient and timely correction. A speaker 314 is fixed on the side wall of the panel 303 near the display screen 306 to issue voice information such as operation instructions. The top of the second mounting base 301 is fixed with a connecting base 304, and a camera 305 is rotatably connected to the middle of the connecting base 304. When the safety officer in the vehicle takes over the vehicle by turning the steering wheel, the steering wheel rotation can drive the counting plate 4 to rotate synchronously. The infrared sensor 9 measures the time, angle, and speed of the steering wheel rotation of the safety officer in the vehicle in real time. When the safety officer in the vehicle takes over the vehicle by pressing the brake pedal, the pressure sensor 14 collects the time and force of the brake pedal pressing of the safety officer in the vehicle in real time. The collected information is transmitted through the connector 302 and stored in the memory 309 in real time, thereby improving the timeliness of data collection and further improving the efficiency and quality of safety officer training.

[0028] Please refer to Figures 2-3The external dimensions of the sleeve 5 are adapted to the internal dimensions of the first slot 8. A second slot 11 is provided on the inner side wall of the first slot 8 for the counting plate 4 to rotate. The output end of the infrared sensor 9 and the slot 6 are located in the same vertical direction, which improves the convenience of installing and positioning the slot 6 and the infrared sensor 9.

[0029] Please refer to Figure 5 A circuit board 307 is fixed on the inner wall of the second mounting base 301 to simplify the circuit. A control chip 308 is fixed on the surface of the circuit board 307 for logic operations and control signal output. An input / output module 310 is fixed on the surface of the second mounting base 301. The input / output module 310 is coupled to the connector 302 in sequence to input and output signals. The connector 302 is coupled to the first terminal 7 and the second terminal 10 respectively. A memory 309 is inserted into the surface of the circuit board 307. A power module 311 is fixed on the surface of the circuit board 307 near the memory 309. The second mounting base 301 is located near the power module. A power connector 312 is inserted into the side wall of module 311. The power connector 312 is coupled to the power module 311 for external power supply. A servo motor 313 is fixed on the side wall of connector 304. The output end of servo motor 313 is fixed on the side wall of camera 305, which improves the convenience of camera 305 angle adjustment. Display screen 306, servo motor 313 and speaker 314 are coupled to input / output module 310 respectively. Two sets of mounting ears 315 are fixed at the bottom of second mounting base 301. The surface of mounting ears 315 is provided with threaded holes to improve the stability of second mounting base 301 installation.

[0030] When using this autonomous driving operation behavior collection device, the operator first fixes the second mounting base 301 to the center console inside the safety officer training vehicle with bolts. Then, the first mounting base 1 and the counting plate 4 are sequentially placed on the outer surface of the vehicle's steering wheel shaft, so that the infrared sensor 9 is facing the slot 6. The protective pad 2 is then attached to the surface of the brake pedal using the first double-sided adhesive 15. The center console, steering wheel shaft, and brake pedal are all existing technologies and will not be described in detail here. When the safety officer inside the vehicle turns the steering wheel, it can drive the counting plate 4 to rotate synchronously. The infrared sensor 9 measures the time, angle, and speed of the safety officer turning the steering wheel in real time. When the safety officer inside the vehicle presses the brake pedal, the pressure sensor 14 collects the time and force of the safety officer pressing the brake pedal in real time. The collected information is transmitted through the connector 302 and stored in the memory 309 in real time, thereby improving the timeliness of data collection and further improving the efficiency and quality of in-vehicle safety officer training.

[0031] Considering the positioning accuracy of the counting plate 4 and the infrared sensor 9, the stability of the sleeve 5 on the outer surface of the steering wheel shaft is improved by setting the anti-slip pad 12. The installation and positioning accuracy of the counting plate 4 and the infrared sensor 9 is improved by opening the second slot 11 for the counting plate 4 to rotate, thereby improving the data acquisition accuracy.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
