[0050] Figure 1 A schematic diagram of the structure of a driving simulation device according to an embodiment of the present invention is shown. As shown in the figure, a driving simulation device 100 suitable for accident assessment mainly includes a base 101, a first support frame 102, a second support frame 103, a driver's seat 104, a steering wheel mechanism 107, a gear shifting mechanism 108, and a display device.
[0051] The first support frame 102 and the second support frame 103 are respectively arranged on both sides of the base 101 along its length.
[0052] The driver's seat 104 is located between the first support frame 102 and the second support frame 103.
[0053] The brake pedal 105 and accelerator pedal 106 are spaced apart on the base 101 and located between the first support frame 102 and the driver's seat 104. This arrangement simulates the setup in a real vehicle, allowing the operator sitting in the driver's seat 104 to operate the brake pedal 105 or accelerator pedal 106 with their feet, thereby simulating the acceleration and deceleration control of the vehicle.
[0054] The steering wheel mechanism 107 is mounted on the first support frame 102 and located above the brake pedal 105 and the accelerator pedal 106. This design allows the operator to easily operate the pedals while holding the steering wheel, ensuring the continuity and convenience of driving operation.
[0055] The gear shifting mechanism 108 is mounted on the base 101 and located on the right side of the driver's seat 104, making it convenient for the operator to shift gears with their right hand during driving, thus making the shifting action smoother and more natural.
[0056] The display device includes a first display screen 109 and a second display screen 110, which are respectively disposed on the top of the first support frame 102 and the second support frame 103.
[0057] The operator is seated in the driver's seat 104 and simulates driving using the brake pedal 105, accelerator pedal 106, steering wheel mechanism 107, and gear shift mechanism 108. The first display screen 109 simulates the operator's view during driving. Through high-definition display and realistic visuals, the operator can perceive various details in the driving scenario, such as road conditions and the surrounding environment, enhancing the realism of the simulated driving. The second display screen 110 displays the actual view of the autonomous vehicle during driving, providing real-time information about the road ahead, traffic signs, other vehicles, and pedestrians perceived by the vehicle in autonomous driving mode. This provides an intuitive perspective for subsequent testing and evaluation of the autonomous vehicle's ability to cope with random traffic flow.
[0058] In some examples, the first display screen 109 and the second display screen 110 are curved screens. The curvature of the curved screen better matches the natural visual curve of the human eye, allowing operators to enjoy a wider and more immersive visual experience when viewing the simulated driving view on the first display screen 109, and for other staff to view the simulated driving view on the second display screen 110, reducing blind spots and the possibility of image distortion. Furthermore, the curved screen design enhances the three-dimensionality and depth of the image, making it more vivid. During simulated driving, it helps operators more accurately judge distances and spatial positions, improving the accuracy and reaction speed of driving operations.
[0059] In some examples, the first display screen 109 and the second display screen 110 are arranged in parallel and at the same height. This parallel arrangement makes the overall structure more harmonious. Setting them at the same height aims to provide operators and other staff with the best visual experience while seated.
[0060] In some examples, the driver's seat 104 is ergonomically designed and can move back and forth along the length of the base 101. The driver's seat 104 is designed with ergonomics in mind, its shape conforming to the curves of the human body, providing good support for the driver's back and hips, effectively reducing fatigue during long drives. Simultaneously, the driver's seat 104 can move back and forth along the length of the base 101. This design allows operators to adjust according to their own body size and driving habits, finding the most comfortable driving position, ensuring convenient and comfortable operation during driving, and improving driving comfort.
[0061] In some examples, the driving simulation device 100 also includes a sensor array. The sensor array includes a brake opening sensor 112 mounted on the brake pedal 105 for accurately detecting the depth of the brake pedal 105. An acceleration opening sensor 113 mounted on the accelerator pedal 106 is used to accurately sense the magnitude of acceleration. A steering angle sensor 114 mounted on the steering wheel mechanism 107 is used to monitor the steering wheel rotation angle in real time. A gear position sensor 115 mounted on the gear shift mechanism 108 acquires gear position information. The sensor information acquired by the sensor array can realistically reflect the simulated driving process of the operator.
[0062] In some examples, the driving simulator 100 also includes a simulation device 111. The simulation device 111 is mounted on a first support frame 102 (not shown). Figure 2 A schematic diagram of the simulation device and sensor group according to an embodiment of the present invention is shown. As shown, the simulation device 111 is electrically connected to the sensor group. The sensor group includes the aforementioned brake opening sensor 112, acceleration opening sensor 113, steering angle sensor 114, and gear position sensor 115. Furthermore, the simulation device 111 is connected to a first display screen 109 and a second display screen 110. Preferably, the simulation device 111 receives sensing signals from the sensor group, such as the opening of the brake pedal 105, the movement of the accelerator pedal 106, the steering wheel angle, and the gear position changes of the shift mechanism 108. The simulation device 111 performs complex calculations and processing based on these signals to simulate the image seen from the operator's actual perspective during driving and sends it to the first display screen 109 for display. This allows the operator to intuitively experience the driving scenario, providing an immersive simulated driving experience.
[0063] In some examples, the simulation device 111 simulates the actual viewpoint of the autonomous vehicle during driving and sends it to the second display screen 110 for display. It should be noted that during the simulation of real driving behavior in a simulated traffic environment, the operator randomly performs dangerous and challenging actions to interfere with the normal driving of the vehicle under test (autonomous vehicle), testing the autonomous driving algorithm of the vehicle under test and detecting its ability to handle challenging behaviors. During the test, the challenging actions performed by the operator include, but are not limited to, rapid entry and exit, sudden braking, and sudden acceleration.
[0064] In some examples, simulation device 111 is configured to simulate a traffic environment. This simulated traffic environment includes highways, urban roads, and rural roads. It also includes environmental parameter settings, such as weather and light intensity. For example, in terms of weather, various weather conditions such as sunny, rainy, and snowy days can be simulated. Light intensity can also be adjusted, such as setting different lighting effects for different times of day, like morning, noon, and evening. The simulated traffic environment can be configured with at least two vehicles: one as the test vehicle, controlled by an external autonomous driving algorithm, and the other as an active challenge test vehicle, flexibly controlled by an operator.
[0065] In some examples, the simulation device 111 also includes a data storage module. This module stores sensor information acquired by the sensor array, speed, acceleration, and position information of the simulated vehicle operated by the operator, and driving data of the autonomous vehicle. Driving data includes whether a collision occurred, driving speed, acceleration, position information, and steering angle information. Collision information provides a basis for subsequent accident analysis and safety performance assessment. Driving data reflects the dynamic changes of the vehicle during operation. Position information clarifies the vehicle's specific coordinates in the simulated environment, while steering angle information reflects the adjustments made to the vehicle's driving direction.
[0066] In some examples, the simulation device 111 also includes a data analysis and processing module and a scene visualization and playback module. The data analysis and processing module can analyze and process the data stored in the data storage module, reconstruct the emergency response scenario of the tested vehicle from a third-party perspective, and visualize it through the scene visualization and playback module. Simultaneously, using the driving data of the tested vehicle and a testing and evaluation scheme, the performance of the autonomous driving algorithm can be evaluated.
[0067] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
