[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] The invention provides a vehicle testing device for automatic driving of a vehicle.

[0051] Please refer to Figure 1 to Figure 2 In a first embodiment of the present invention, a vehicle testing device for automatic driving of a vehicle comprises:

[0052] Install the cross frame 1;

[0053] A moving mechanism 2, wherein the moving mechanism 2 is installed on the mounting cross frame 1;

[0054] The roadblock mechanism 3 includes a connecting frame 31, a release assembly 32 and a dropped object 33. The connecting frame 31 is fixedly mounted on the moving end of the moving mechanism 2. The moving mechanism 2 is used to drive the connecting frame 31 to move horizontally along the top of the mounting cross frame 1. The release assembly 32 includes a second motor 321, a release rope 322 and a mounting cover 323. The second motor 321 is fixedly mounted on the connecting frame 31. The mounting cover 323 is arranged around the shaft end of the second motor 321 and is fixedly mounted on the connecting frame 31. A release port is provided at the bottom of the mounting cover 323. One end of the release rope 322 passes through the release port and is wound and fixed with the shaft end of the second motor 321. The other end of the release rope 322 is fixedly connected to the dropped object 33.

[0055] The bottom of the mounting cross frame 1 is provided with a counterweight (not shown in the figure) for pressing the mounting cross frame 1 to maintain its stability during use.

[0056] In a preferred embodiment of the present invention, the connecting frame 31 is equipped with a distance measuring device, which integrates a distance sensor and a visual sensor. The output end of the distance measuring device is connected to the control end of the second motor 321 by signal.

[0057] Used to identify the autonomous driving vehicle and determine whether the autonomous driving vehicle has reached the preset detection distance;

[0058] If yes, the second motor 321 is started, and the second motor 321 releases the dropped object 33 through the release rope 322. The dropped object 33 automatically falls to the ground under the action of gravity and is located on the driving path of the autonomous driving vehicle, so that the autonomous driving vehicle drives to the preset detection distance;

[0059] If not, the second motor 321 is in a braking state, and the dropped object 33 remains in a retracted state and cannot move downward.

[0060] Before obstacle detection, the moving mechanism 2 conveniently drives the roadblock mechanism 3 to switch the release position, which can be applicable to obstacle detection of autonomous driving vehicles on different roads;

[0061] After the detection is completed, the second motor 321 can also recover the dropped object 33 through the release rope 322, so as to automatically retract the dropped object 33 after the obstacle detection, and provide support for the next test;

[0062] Finally, a set of the roadblock mechanism 3 can realize the station switching between different roads and the obstacle detection of the autonomous driving vehicle; at the same time, after completing an obstacle drop detection, the dropped object 33 can be automatically retrieved.

[0063] Please refer to Figure 2 and Figure 3 The falling object 33 includes a fixed frame 331, two elastic covers 332 and two movable plates 333. The top of the fixed frame 331 is fixedly arranged at the other end of the release rope 322. The elastic cover 332 is fixedly connected to the fixed frame 331 and the movable plate 333. The two elastic covers 332 are symmetrically connected to the two ends of the fixed frame 331.

[0064] A cavity 330 is formed between the fixing frame 331 , the two elastic covers 332 , and the two movable plates 333 . The cavity 330 is filled with buffer gas.

[0065] In this embodiment, the elastic cover 332 is an elastic plastic structure, which provides support for the subsequent elastic contraction or elastic extension of the dropped object 33.

[0066] By filling with buffer gas, the dropped object 33 will not be damaged even if it is pressed or hit during the detection and use, which facilitates the recovery and use of the dropped object 33 and reduces vehicle damage and obstacle consumption caused by collision with the vehicle during obstacle detection.

[0067] Furthermore, the dropped object 33 also includes an air filling nozzle 334 , which is mounted on the fixing frame 331 , and an output end of the air filling nozzle 334 is connected to the cavity 330 .

[0068] In this embodiment, the inflation nozzle 334 is connected to an external inflation device for inflation; the inflation nozzle 334 can also be deflated by pressing the valve core.

[0069] When the cavity 330 is inflated, the volume of the dropped object 33 increases;

[0070] When the cavity 330 is deflated, the volume of the dropped object 33 is reduced.

[0071] The inflation nozzle 334 facilitates inflation or deflation within the cavity 330 . Without replacing the dropped object 33 , the volume of the dropped object 33 can be controlled according to actual detection requirements, thereby increasing the actual detection volume of the dropped object 33 during obstacle detection, thereby determining the reliability of the autonomous driving vehicle in identifying obstacles of different volumes.

[0072] The use of falling object testing equipment can provide scientific and objective testing methods and data support for the formulation of autonomous driving industry standards. By conducting unified falling object tests on different autonomous driving systems, a set of standardized testing processes and evaluation indicators can be established to ensure that the autonomous driving technologies of different manufacturers reach a certain level in terms of safety and reliability.

[0073] In actual application scenarios, there are not only dropped objects, but also the phenomenon of edge roads being occupied. Therefore, the need for edge road occupation detection is equally important.

[0074] Please refer to Figure 1 and Figure 4 The automobile testing equipment for automatic driving of an automobile further comprises a first rotating member 4 and a blocking mechanism 5, wherein the first rotating member 4 is mounted on the mounting cross frame 1;

[0075] The blocking mechanism 5 includes a rotating shaft 51, an obstacle plate 53 and a second rotating member 54. The rotating shaft 51 is rotatably mounted on the rotating end of the first rotating member 4, and the second rotating member 54 is mounted on the rotating end of the first rotating member 4. The obstacle plate 53 is mounted on the rotating shaft 51. The second rotating member 54 is used to drive the rotating shaft 51 to rotate and adjust, so as to unfold the obstacle plate 53. The first rotating member 4 is used to drive the obstacle plate 53 to rotate and adjust after unfolding, so as to switch the working position of the obstacle plate 53.

[0076] The second rotating member 54 facilitates the flipping of the barrier plate 53 so that it can be unfolded when in use and folded up when not in use; when folded up, it can reduce the space occupied by the road and ensure normal smooth driving on the road; and the use and adjustment of the barrier plate 53 are more free.

[0077] The deployment principle of the barrier plate 53 is as follows:

[0078] When the barrier plate 53 needs to be used, the second rotating member 54 is started, the second rotating member 54 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the barrier plate 53 to switch from a horizontal storage state to a vertical use state;

[0079] The storage principle of the barrier plate 53 is as follows:

[0080] When the barrier plate 53 is not needed, the second rotating member 54 is started, the second rotating member 54 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the barrier plate 53 to switch from the vertical use state to the horizontal storage state.

[0081] In this embodiment, the first rotating member 4 is installed at the middle position of the top wall of the mounting cross frame 1 .

[0082] The first rotating member 4 facilitates the control of the barrier plate 53 to adjust the use position to adapt to the switching between different lanes; it is used for lane blocking between different lanes to simulate the actual application scenario that there are vehicles occupying the lane next to the falling object lane and it is impossible to change lanes to avoid them, and simulates different obstacle detection scenarios to meet the needs of the actual driving environment.

[0083] In this embodiment, the blocking mechanism 5 further includes a damping member 52, and the barrier plate 53 is rotatably mounted on the rotating shaft 51 through the damping member 52. The damping member 52 is used to maintain the stability of the barrier plate 53 in use; when the autonomous driving vehicle avoids and collides with the barrier plate 53, the barrier plate 53 can adaptively rotate on the rotating shaft 51 through the damping member 52, thereby avoiding collision damage to the barrier plate 53 and extending the service life of the barrier plate 53.

[0084] In an optional implementation of the present embodiment, the moving mechanism 2 can be any one of a telescopic cylinder, an electric telescopic lever, and a hydraulic telescopic lever, which is used to directly drive the connecting frame 31 to move horizontally along the top of the mounting cross frame 1, thereby facilitating the switching of the roadblock mechanism 3 for testing between different roads.

[0085] Please refer to Figure 1 and Figure 4 In another optional implementation of the present embodiment, the moving mechanism 2 includes a first motor 21, a screw rod 22 and a slide 23, the fixed end of the first motor 21 is fixed on the mounting cross frame 1, one end of the screw rod 22 is fixedly connected to the shaft end of the first motor 21, the other end of the screw rod 22 passes through the slide 23 and is threadedly connected, and the slide 23 is slidably installed on the top of the mounting cross frame 1; the connecting frame 31 is fixed on the slide 23.

[0086] In this embodiment, the first motor 21 provides a power source for the rotation adjustment of the screw rod 22 .

[0087] Movement and adjustment principle: when it is necessary to switch the work position of the roadblock mechanism 3, start the first motor 21, the first motor 21 drives the screw rod 22 to rotate, and when the screw rod 22 rotates, it drives the slide 23 to move horizontally along the top of the mounting cross frame 1. When the slide 23 moves, it drives the roadblock mechanism 3 to move and adjust as a whole, providing a power source for the work position switching of the roadblock mechanism 3.

[0088] Please refer to Figure 4 and Figure 5 The first rotating member 4 includes a rotating cover 41, a support plate 42, a telescopic member 43, a first gear 44 and a first rack 45. The rotating cover 41 passes through the mounting cross frame 1 and is rotatably connected. The support plate 42 is fixed on the inner wall of the rotating cover 41. The fixed end of the telescopic member 43 is fixed on the support plate 42. The telescopic end of the telescopic member 43 is fixedly connected to the first gear 44. The top of the first rack 45 is fixed on the slide seat 23.

[0089] The first gear 44 corresponds to the first rack 45 up and down. When the first gear 44 is separated from the first rack 45, the roadblock mechanism 3 is controlled separately; when the first gear 44 is engaged with the first rack 45, the roadblock mechanism 3 is controlled synchronously.

[0090] In this embodiment, the telescopic member 43 can only drive the first gear 44 to telescope and adjust, and relative rotation cannot occur between the two. Therefore, when the first gear 44 rotates, the first gear 44 can synchronously drive the support plate 42 and the rotating cover 41 to rotate through the telescopic member 43, so as to drive the obstacle plate 53 to rotate and adjust.

[0091] In this embodiment, the roadblock mechanism 3 includes two usage states:

[0092] In the separate control state, the first gear 44 is separated from the first rack 45, and the roadblock mechanism 3 is switched to separate control state, which is used for the test scenario of the marginal road without occupying the road;

[0093] In the synchronous control state, the first gear 44 is meshed with the first rack 45, and the state switching of the roadblock mechanism 3 is synchronously controlled with the adjustment of the barrier plate 53, which is used for the test scenario where the edge road is occupied.

[0094] When it is necessary to control the roadblock mechanism 3 to switch the working position separately, the telescopic member 43 is started, and the telescopic member 43 drives the first gear 44 to move downward and retract, and the first gear 44 is separated from the first rack 45. After the moving mechanism 2 is started, it can drive the roadblock mechanism 3 to move and adjust separately, so as to switch the working position of the roadblock mechanism 3;

[0095] When it is necessary to synchronously control the roadblock mechanism 3 and the blocking mechanism 5, the telescopic member 43 is started, and the telescopic member 43 drives the first gear 44 to move upward, and the first gear 44 is engaged with the first rack 45. After the above-mentioned moving mechanism 2 is started, it can drive the roadblock mechanism 3 to move horizontally and adjust the work position. During the movement and adjustment of the roadblock mechanism 3, the first rack 45 synchronously drives the first gear 44 to rotate. When the first gear 44 rotates, the rotating cover 41 is driven to rotate and adjust through the telescopic member 43 and the support plate 42. When the rotating cover 41 rotates, the unfolded obstacle plate 53 is driven to rotate adaptively. When the dropped object 33 is detected, a simulation scene of the edge road being occupied is provided to simulate a real application scene;

[0096] Finally, when the device is in a single control state, the roadblock mechanism 3 is convenient for controlling the switching of workstations individually to simulate a simulated scene in which the edge road is unobstructed or occupied; when the device is in a synchronous control state, the roadblock mechanism 3 can synchronously drive the automatic switching of the barrier plate 53 while switching the workstation to simulate a virtual scene in which the edge road is blocked or occupied.

[0097] In an optional implementation of the present embodiment, the second rotating member 54 is a separate driving motor, the fixed end of the driving motor is fixed on the rotating cover 41, the shaft end of the driving motor passes through the rotating cover 41 and is rotatably connected, and the rotating shaft 51 is fixed on the shaft end of the driving motor; it is convenient for the driving motor to directly drive the rotating shaft 51 for rotation adjustment.

[0098] Please refer to Figure 4 and Figure 6 In another optional implementation manner of the present embodiment, the second rotating member 54 includes a second rack 541 and a second gear 542, the top of the second rack 541 is fixedly connected to the first gear 44, the rotating shaft 51 passes through the rotating cover 41 and is rotatably connected, the second gear 542 is fixed on the rotating shaft 51, and the second gear 542 is located in the rotating cover 41 and meshes with the second rack 541.

[0099] When the roadblock mechanism 3 switches from the individual control state to the synchronous control state, the first gear 44 also synchronously drives the second rack 541 to move upward, and the second rack 541 drives the second gear 542 to rotate while moving upward. When the second gear 542 rotates, it synchronously drives the rotating shaft 51, the damping member 52 and the barrier plate 53 to rotate and unfold, thereby providing support for the road occupation test at the edge of the road.

[0100] During the process of the roadblock mechanism 3 switching from the synchronous control state to the individual control state, the first gear 44 also synchronously drives the second rack 541 to move downward, and the second rack 541 moves downward while driving the second gear 542 to rotate. When the second gear 542 rotates, it synchronously drives the rotating shaft 51, the damping member 52 and the obstacle plate 53 to rotate and be stored, thereby providing support for the road edge non-occupancy test.

[0101] In a preferred embodiment of the present invention, a warning light group (not shown) is integrated on the barrier plate 53 to facilitate simulating the taillights of a car during the test of the barrier plate 53 occupying the road, and to simulate the obstacle detection of the automatic driving of the car at night.

[0102] Please refer again Figure 5The automobile test equipment for automatic driving of automobiles further comprises a damping mechanism 6, which comprises an elastic telescopic member 61 and a damping plate 62, wherein the fixed end of the elastic telescopic member 61 is fixedly arranged on the top of the mounting cross frame 1, and the damping plate 62 is fixedly arranged on the telescopic end of the elastic telescopic member 61, and the surface of the damping plate 62 is attached to the surface of the rotating cover 41. The rotating cover 41 does not need to be rotated and adjusted to a friction brake.

[0103] When the roadblock mechanism 3 is in a single control state, the rotating cover 41 and the barrier plate 53 can be stably maintained in the switched state without automatic rotation.

[0104] The working principle of the automobile testing equipment for automatic driving of automobiles provided in this embodiment is as follows:

[0105] When the road does not require lane detection:

[0106] First, the telescopic member 43 is activated, and the telescopic member 43 drives the first gear 44 to move downward, and the first gear 44 is separated from the first rack 45 when moving downward;

[0107] Before the moving mechanism 2 controls the movement and adjustment of the dropped object 33, the dropped object 33 is located in the middle of the top wall of the mounting cross frame 1; during adjustment, the first motor 21 is started, the first motor 21 drives the screw rod 22 to rotate, the screw rod 22 drives the slide 23 to move, and when the slide 23 moves, it drives the roadblock mechanism 3 to move as a whole, so that the roadblock mechanism 3 moves to the middle of the road for use;

[0108] When the autonomous driving vehicle drives automatically along the passage road to the detection range of the distance measuring device, the second motor 321 is automatically started, and the second motor 321 drives the release rope 322 and the dropped object 33 to automatically fall, so that the dropped object 33 falls on the passage road of the autonomous driving vehicle, providing support for the detection of the autonomous driving vehicle when the passage road is not occupied;

[0109] When the road needs to be checked:

[0110] It may be defined that, in the initial state, the roadblock mechanism 3 is located in the middle of the top wall of the mounting cross frame 1, and the middle of the first rack 45 is aligned with the first gear 44 in the vertical direction;

[0111] Please refer to Figure 4 and Figure 7, first start the telescopic member 43, the telescopic member 43 drives the first gear 44 to move upward, and the first gear 44 engages with the first rack 45 when moving upward; when the first gear 44 moves upward, it also drives the second rack 541 to move upward, and when the second rack 541 moves upward, it drives the second gear 542 to rotate, and when the second gear 542 rotates, it drives the rotating shaft 51 to rotate, and when the rotating shaft 51 rotates, it drives the barrier plate 53 to rotate and unfold through the damping member 52, so that the barrier plate 53 switches from the storage state to the unfolded state;

[0112] Please refer to Figures 8 to 10 Before the moving mechanism 2 controls the movement and adjustment of the dropped object 33, the dropped object 33 is located in the middle of the top wall of the mounting cross frame 1; during adjustment, the first motor 21 is started, the first motor 21 drives the screw rod 22 to rotate, the screw rod 22 drives the slide 23 to move, and when the slide 23 moves, it drives the roadblock mechanism 3 to move as a whole, so that the roadblock mechanism 3 moves to the middle of the road for use;

[0113] Please refer again Fig. 9 and Fig.10 When the slide 23 moves right, the slide 23 also drives the first rack 45 to move right. When the first rack 45 moves right, it drives the first gear 44 in the meshing state to rotate counterclockwise. The first gear 44 drives the rotating cover 41 to rotate counterclockwise synchronously through the telescopic member 43 and the support plate 42. The rotating cover 41 drives the rotating shaft 51, the damping member 52 and the obstacle plate 53 in the expanded state to flip counterclockwise by 90°. The obstacle plate 53 blocks an edge road, providing an obstacle detection application scenario for an occupied edge road for an autonomous driving vehicle.

[0114] Similarly, please refer to Fig.11 and Fig.12 When the slide 23 moves left, the slide 23 also drives the first rack 45 to move left. When the first rack 45 moves left, it drives the first gear 44 in meshing state to rotate clockwise. The first gear 44 drives the rotating cover 41 to rotate clockwise synchronously through the telescopic member 43 and the support plate 42. The rotating cover 41 drives the rotating shaft 51, the damping member 52 and the obstacle plate 53 in the expanded state to rotate 90° clockwise. The obstacle plate 53 blocks another edge road, providing an obstacle detection application scenario of edge road occupancy during different road detections for autonomous driving vehicles.

[0115] Finally, in the process of switching the roadblock mechanism 3 from the individual control state to the synchronous control state, the barrier plate 53 is automatically deployed simultaneously;

[0116] During the process of switching the use position of the roadblock mechanism 3, the automatic rotation of the barrier plate 53 is synchronously realized, so that the barrier plate 53 can be adaptively rotated to the corresponding traffic road according to the use requirements, providing support for the detection of occupied lanes on edge roads for autonomous driving vehicles.
