[0029] As mentioned above, traditional driving training methods typically involve real vehicles, which presents numerous challenges. Firstly, using real vehicles for driving training is costly, including vehicle purchase, maintenance, fuel consumption, and insurance costs. Secondly, training in real vehicles can be dangerous, especially for beginners, as it can lead to traffic accidents, resulting in casualties and property damage.

Typical virtual driving simulators of the same type are relatively large, occupying significant space and creating inconveniences during installation and use. Furthermore, the high cost of these simulators limits their widespread adoption in some research institutions and businesses.

Furthermore, the portable vehicle driving simulation method provided in the second aspect of the present invention may be implemented based on the portable vehicle driving simulation device provided in the first aspect of the present invention.

[0032] Please refer to Figure 1 . Figure 1 A schematic structural diagram of a portable car driving simulation device provided according to some embodiments of the present invention is shown.

[0033] exist Figure 1In the illustrated embodiment, the portable car driving simulation device provided by the second aspect of the present invention includes a wheel support module 11, a road condition simulation module 12, a data acquisition module, a simulation computer 13, a display module 14 (e.g., a display screen), and a data analysis module. Here, the wheel support module 11 is used to support the vehicle 20 to be driven.

The display module 14 is used to display the road conditions and training screen data to the driver in real time. The data analysis module is used to evaluate the driver's skill score based on the road conditions and various parameters.

[0034] Please refer to further Figures 2 to 7 . Figure 2 A schematic structural diagram of a road condition simulation module provided according to some embodiments of the present invention is shown. Figure 3 A cross-sectional schematic diagram of a road condition simulation module provided according to some embodiments of the present invention is shown. Figure 4 A schematic diagram illustrating implementation of wheel rolling resistance according to some embodiments of the present invention is shown. Figure 5 A schematic diagram illustrating implementation of wheel steering resistance according to some embodiments of the present invention is shown. Figure 6 A schematic diagram of road condition vibration simulation provided according to some embodiments of the present invention is shown. Figure 7 A partially enlarged schematic diagram of a wheel steering resistance cam friction plate provided according to some embodiments of the present invention is shown.

[0035] exist Figure 2 In the illustrated embodiment, the road condition simulation module 12 consists of a wheel multifunctional device 121, a framework, and cable ducts 122. This module 12 simulates vehicle steering, wheel speed, and road vibration, providing the driver with a realistic driving experience. The wheel multifunctional device 121 simulates wheel rotation and steering. The framework and cable ducts 122 connect the various wheel multifunctional devices, forming a complete system framework and routing electrical wiring within it.

[0036] Further, in Figure 3In the illustrated embodiment, the wheel multi-function device 121 includes an axle 123, an axle bracket 124, a rotating shaft 125, a housing support structure 126, and a road condition vibrator 127. The axle 123 is located below the wheel and is used to drive the wheel to rotate along the horizontal axis a to simulate the rotation of the wheel during vehicle travel. The axle bracket 124 supports the axle 123 and the wheel. The rotating shaft 125 is located at the center of the axle bracket 124 and is used to drive the axle bracket 124 and the wheel to rotate along the vertical axis b to simulate the turning of the wheel during vehicle travel. The housing support structure 126 supports the axle 123, axle bracket 124, the rotating shaft 125, and the wheel. The road condition vibrator 127 is driven by an electric cylinder and, based on simulated road surface input signals, drives the housing support structure 126 to vibrate up and down in the direction c to simulate the heaving of the wheel during vehicle travel.

[0037] Specifically, in Figure 3 In the illustrated embodiment, axle 123 is mounted in a hole in axle bracket 124. Axle 123 of road condition simulation module 12 can rotate along this axis. The weight of the wheel exerts pressure on axle 123. When the wheel rotates, axle 123 and the wheel can roll relative to each other, thereby achieving wheel rotation. Furthermore, axle-rotating needle bearing 128 is mounted between axle bracket 124 and wheel lower bracket 129. The three are fixedly connected by a rotating shaft 125 and can rotate coaxially. This ensures that when the driver turns the steering wheel, the wheel rotates perpendicular to the ground.

[0038] exist Figure 4 In the illustrated embodiment, to simulate the effects of wheel rolling resistance, the road condition simulation module 12 installs an axle rolling resistance friction plate 131 on the wheel axle 123. This friction plate can rotate along the axle rolling resistance rotating pin 130. A wheel rolling resistance pressure controller 132 is fixedly connected to the axle rolling resistance friction plate 131 and can extend or retract axially, thereby driving the axle rolling resistance friction plate 131 downward or rebound. The magnitude of rolling resistance is simulated by the magnitude of friction, thereby achieving the wheel rolling resistance effect.

[0039] exist Figure 5 In the illustrated embodiment, to simulate wheel steering resistance, the road condition simulation module 12 mounts a wheel steering resistance cam friction plate 133 and a wheel steering resistance controller 134 on the axle lower bracket 129. 133 and 124 are in surface contact. The wheel steering resistance controller 134 controls the rotation angle of the wheel steering resistance cam friction plate 133. Due to the cam's arc shape, the friction plate applies varying pressures to the axle bracket 124. As the rotation angle changes, the rotational friction between the axle bracket 124 and the axle lower bracket 129 is controlled, thereby simulating wheel steering resistance.

[0040] exist Figure 6 and Figure 7 In the illustrated embodiment, the road condition simulation module 12 includes three road condition vibrators 127 , each having a telescopic column, which simulates the road condition vibration of each wheel by controlling the telescopic amount and frequency.

[0041] In addition, Figure 1 In the illustrated embodiment, the road condition simulation module 12 is connected to a vehicle support device 11, which includes a front wheel steering support device and a rear wheel roller support device. Here, the front wheel steering support device is used to support the wheel to rotate left and right in the horizontal direction to simulate the steering wheel operation during driving. The rear wheel roller support device is used to ensure the stability of the wheel in the vertical direction and to support the rolling of the wheel. In this way, the vehicle support device 11 provided in the first aspect of the present invention can achieve all-round support for the vehicle wheels and simulation of the driving process based on the structural design of the front wheel steering support device and the rear wheel roller support device.

[0042] In addition, Figure 1 In the illustrated embodiment, the road condition simulation module 12 is connected to a data acquisition module, which includes multiple sensors. Here, the first sensor is located on the wheel to detect the wheel axle speed. The second sensor is located on the steering wheel attachment to detect the steering wheel's axis of rotation. The third sensor is located on the accelerator pedal to detect the accelerator pedal position after the driver presses the accelerator.

[0043] In addition, Figure 1 In the embodiment shown, the road condition simulation module 12 is connected to a display module 14, which is composed of a plurality of flexible screen modules. Here, the display module 14 has a preset curvature to enhance the visual effect of the display module 14 and widen the viewing angle.

[0044] Specifically, the display module 14 uses high-resolution display technology to ensure clear and smooth images, providing the driver with intuitive and realistic road conditions. Here, the above-mentioned road conditions include straight roads, curves, slopes, and bumpy roads.

[0045] In some optional embodiments, the portable car driving simulator provided by the first aspect of the present invention also includes an advertising module. This module serves as an additional functional component, providing additional advertising space. This module's display can be customized with customized advertising content, enhancing the device's practicality and commercial value. When used in a showroom, the advertising module can attract more customers and boost vehicle sales.

[0046] Furthermore, in some non-limiting embodiments, the portable vehicle driving simulation device provided in the first aspect of the present invention includes a memory and a controller. The memory includes, but is not limited to, the computer-readable storage medium provided in the third aspect, which stores computer instructions. The controller is connected to the memory and configured to execute the computer instructions stored in the memory to implement the portable vehicle driving simulation method provided in the first aspect of the present invention.

[0047] The following describes the aforementioned operating principles in conjunction with several examples of portable car driving simulation methods. Those skilled in the art will appreciate that these examples of driving simulation methods are merely non-limiting implementations of the present invention, intended to clearly demonstrate the main concepts of the present invention and provide specific solutions for easy implementation by the public. They do not limit the full functionality or operation of the portable car driving simulation device. Similarly, the driving simulation device is merely a non-limiting implementation of the present invention and does not restrict the execution of the various steps in the driving simulation method or the order in which they are performed.

[0048] Please refer to Figure 8 . Figure 8 A schematic flow chart of a portable car driving simulation method provided according to some embodiments of the present invention is shown.

[0049] like Figure 8 As shown, the technician may first support the vehicle 20 to be driven via the wheel support module 11 in the portable vehicle driving simulation device provided by the second aspect of the present invention.

[0050] Afterwards, the technician can simulate the driving process of the vehicle 20 based on the pre-acquired road conditions through the road simulation module 12. Here, the road conditions include straight roads, curves, slopes, and bumpy roads.

[0051] Specifically, the controller of the driving simulation device can calculate the road vibration force, current rolling resistance, and steering resistance based on the vehicle's wheel speed, the driver's steering input, and the vehicle's road conditions. The controller can then transmit the calculated vibration force to the road vibrator 127 to simulate the vehicle's up and down vibration.

[0052] In addition, the controller can also transmit the calculated rolling resistance to the axle rolling resistance pressure controller 132 to simulate the rolling resistance of the vehicle's current road conditions. The mechanical structure realizes wheel rolling through the axle 123 and can also control the rolling resistance.

[0053] In addition, the controller can also calculate the steering resistance wheel steering resistance controller 134 to simulate the steering resistance of the vehicle's current road conditions. The mechanical structure realizes wheel steering through the rotating shaft 125 and can control the steering resistance at the same time.

[0054] Afterwards, the technician can use the data acquisition module to collect multiple parameters of the vehicle 20 during driving. Here, the parameters include at least the wheel axle speed, the steering wheel shaft deflection angle, and the accelerator pedal position.

[0055] Afterward, technicians can use the simulation computer 13 to generate training images of the driver during driving based on multiple parameters and road conditions, ensuring the efficient and stable operation of the portable vehicle driving simulator provided by the first aspect of the present invention. Specifically, the simulation computer 13 has powerful computing capabilities and abundant interface resources, capable of simultaneously processing data from multiple components such as the data acquisition module and display module 14, and generating real-time images of road conditions and driving feedback.

[0056] Afterwards, the technician can display the road conditions and training screen data to the driver in real time via the display module 14 .

[0057] Afterwards, technicians can use the data analysis module to evaluate the driver's skill score based on road conditions and various parameters.

[0058] Furthermore, the aforementioned driver skills include basic driving skills. Specifically, technicians can determine the driver's control accuracy based on the vehicle's steering wheel correction frequency. In response to the driver's steering wheel correction frequency being less than 0.2 Hz, the driver's control accuracy is determined to be excellent.

[0059] In addition, in some embodiments, technicians can also determine the driver's power coordination based on the vehicle's throttle and brake response time difference. In response to the driver's throttle and brake response time difference being less than 300ms, the driver's power coordination is determined to be excellent.

[0060] In addition, in some embodiments, the technician may also determine the driver's vehicle speed stability based on the vehicle's speed fluctuation rate under standard operating conditions. In response to the driver's speed fluctuation rate under standard operating conditions being less than or equal to 5%, the driver's vehicle speed stability is determined to be excellent.

[0061] Furthermore, the aforementioned driver skills also include the ability to handle complex road conditions. Specifically, technicians can determine the driver's obstacle avoidance capabilities based on the vehicle's advance recognition distance and braking timing.

[0062] Furthermore, in some embodiments, technicians can also determine the driver's lane keeping ability based on the heading angle deviation index when the vehicle is traveling on a curve.

[0063] In addition, in some embodiments, technicians can also determine the driver's emergency response capability based on the vehicle's decision-making time window in an emergency situation. If the driver's decision-making time window in an emergency situation is less than 1.5 seconds, the driver's emergency response capability is determined to meet the standard.

[0064] Furthermore, in some preferred embodiments, in the process of evaluating the driver's skill score, technicians can also first perform spatiotemporal alignment and fusion of various parameters such as the vehicle steering angle, throttle opening, steering wheel angle, lane offset, distance, etc., and use a feature weight dynamic allocation model based on the attention mechanism to evaluate the driver's skill score, thereby solving the limitations of the single-dimensional evaluation of traditional evaluation technology.

[0065] In summary, the above-mentioned road condition simulation module, portable vehicle simulation driving device, portable vehicle simulation driving method and computer-readable storage medium provided by the present invention can all be used to perform simulated driving training on the driver when the vehicle is stationary by setting the coordination between the wheel axle, wheel axle bracket, rotating shaft, shell support structure and road condition vibrator, thereby improving the accuracy and comprehensiveness of the driving training evaluation results.
