[0048] 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.

[0049] The present invention provides an automatic driving safety testing system for an intelligent networked vehicle.

[0050] Please refer to Figures 1 to 4 , In one embodiment of the present invention, the autonomous driving safety test system of the intelligent networked car comprises: a test car 1, a rain simulation device 2, a moving obstacle 3 and a detection device 4;

[0051] The rainwater simulation device 2 includes a rain box 21, a water supply device 22, a mounting frame 23 and a perforated plate 24. The rain box 21 is mounted on the roof of the test vehicle 1 through the mounting frame 23 and is suspended at the front side of the vehicle. The perforated plate 24 is arranged at the bottom of the rain box 21. The output end of the water supply device 22 is connected to the water inlet pipe 211 of the rain box 21. The water supply device 22 is used to input test water into the rain box 21.

[0052] The detection device 4 is used to control the movement of the moving obstacle 3;

[0053] When the detection device 4 detects the moving test vehicle 1, the detection device 4 controls the moving obstacle 3 to move in a direction perpendicular to the moving direction of the test vehicle 1;

[0054] During testing, if Figure 2The mobile obstacle 3 is set on one side of the test track and faces the test intersection. The detection device 4 is set on one side of the test track and is at a preset distance from the mobile obstacle 3. During the test, the test vehicle 1 travels along the test track at a preset speed. When the detection device 4 detects the test vehicle 1, the mobile obstacle 3 is controlled to travel along the test intersection to detect whether the test vehicle 1 can stop safely without hitting the mobile obstacle 3. After passing safely, the distance between the detection device 4 and the mobile obstacle 3 can be adjusted to detect the final safe distance of the test vehicle 1 at the current speed, that is, it will not collide with the mobile obstacle 3 within the safe distance.

[0055] Then, the rain simulation device 2 is used to simulate rainy weather, and the above test steps are repeated to detect the safe distance of the test vehicle 1 in rainy weather, so that the safe driving performance of the test vehicle 1 in the simulated rainy weather can be detected.

[0056] During the test, the preset speed of the vehicle can be changed for testing, such as 60km / h, 55km / h, 50km / h, etc., and the preset distance can be tested in a decreasing manner, such as 100m, 90m, etc.

[0057] The rainwater simulation device 2 is used to simulate the impact of rainy weather on the test vehicle 1, and other tests can also be carried out, such as setting cones, manhole covers, pits, triangle signs, etc. on a road to test whether the test vehicle 1 can identify them and pass safely. Various traffic warning signs, traffic lights, etc. can also be set to test whether they can be identified.

[0058] At the same time, a signal interference source may be set on the test road to detect the impact on the safe passage of the test vehicle 1 when the communication signal is interfered.

[0059] In this embodiment, the water supply device 22 includes a water tank, a water pump and multiple water pipes. The input end of the water pump is connected to the water tank through a delivery pipe, and the output end of the water pump is connected to the water inlet pipe 211 of the rain box 21 through a water delivery pipe. The water tank can be set inside or on the top of the test vehicle 1.

[0060] When the rainwater simulation device 2 is in use, the water pump works to input the water in the water tank into the interior of the rain outlet box 21 through the water pipe, and the water flows out through the orifice plate 24 at the bottom of the rain outlet box 21 to form rainwater and fall on the front of the test vehicle 1.

[0061] Please refer again Figure 1 In this embodiment, the mobile obstacle 3 includes a driving trolley 31 , a connecting rod 32 and a bionic component 33 . The connecting rod 32 is installed on the driving trolley 31 , and the bionic component 33 is installed on the connecting rod 32 .

[0062] When in use, the driving vehicle 31 drives the bionic component 33 through the test intersection through the connecting rod 32, thereby simulating pedestrians or pedestrians riding bicycles.

[0063] The bionic part 33 is a sign in the shape of a human, a person riding an electric vehicle, or a person riding a bicycle.

[0064] The bionic part 33 and the connecting rod 32 can be detachably installed. A hole can be opened on the bionic part 33 and it can be tied to the connecting rod 32 by ropes or wires, or holes can be opened on both the bionic part 33 and the connecting rod 32 and they can be installed by bolts and nuts.

[0065] In other embodiments, a mounting seat or the like may be provided on the top of the driving trolley 31 to mount and fix the bionic component 33 , such as a clamping seat to clamp and fix the bionic component 33 .

[0066] Please refer again Figure 1 The detection device 4 includes a moving frame 41 and a detection unit 42. The detection unit 42 is arranged on the moving frame 41, so as to facilitate the movement of the entire detection device 4. The detection unit 42 includes a detection sensor, a communication module and a controller.

[0067] The detection sensor, controller, communication module and driving vehicle 31 are connected in sequence by signals. When the detection sensor detects the test vehicle 1, the detection sensor transmits the signal to the controller, and the controller controls the driving vehicle 31 to move through the test intersection through the communication module.

[0068] The detection sensor can be a photoelectric switch, a laser sensor, etc.

[0069] See also Figure 3 As a preferred embodiment of this embodiment, the autonomous driving safety test system for the smart networked car further includes a rainfall regulating device 5, which is used to adjust the amount of rain output by the rain simulation device 2.

[0070] By providing the rainfall regulating device 5 and cooperating with the water supply device 22 , the amount of rain discharged by the rainwater simulation device 2 can be adjusted to detect the impact of different rainfall amounts on the test vehicle 1 .

[0071] During adjustment, the power of the water pump in the water supply device 22 is adjusted accordingly, thereby adjusting the water pressure entering the rain outlet box 21, and cooperating with the rainfall regulating device 5 to adjust the rainfall amount.

[0072] See also Figure 3 and Figure 4As an optional method of this embodiment, the rain regulating device 5 includes a driven shaft 51, a driving shaft 52, a motor 53, an adjusting belt 54 and a transmission member 55. The driven shaft 51 and the driving shaft 52 are rotatably mounted on both sides of the rain outlet box 21 respectively. One end of the adjusting belt 54 is wound around and mounted on the driven shaft 51, and the other end passes through the rain outlet box 21 through the strip opening 212 and is connected to the driving shaft 52. The motor 53 is installed on the rain outlet box 21 through a fixing frame 531. The output end of the motor 53 is connected to the driving shaft 52. The driven shaft 51 and the driving shaft 52 are connected to each other through a transmission member 55. A plurality of hole surfaces are opened on the adjusting belt 54, and the apertures of the plurality of hole surfaces decrease sequentially.

[0073] In this embodiment, the hole surface is a surface formed by a plurality of holes on the adjusting belt 54, and the hole diameter of the hole surface on the adjusting belt 54 on the driven shaft 51 side is larger than the hole diameter of the hole surface on the adjusting belt 54 on the driving shaft 52 side. The area of ​​each hole surface corresponds to the area of ​​the bottom of the inner cavity of the rain box 21.

[0074] During the test, the hole surface with the smallest aperture is first used to align with the orifice plate 24. At this time, the rainfall is the smallest. When the rainfall is increased, the motor 53 drives the driving shaft 52 to rotate clockwise. The driving shaft 52 drives the driven shaft 51 to rotate through the transmission member 55. The driven shaft 51 releases the adjusting belt 54 while the driving shaft 52 winds the adjusting belt 54, so that the hole surface with a larger diameter moves into the rain box 21 and is aligned with the orifice plate 24. The power of the water pump is adjusted to achieve the function of increasing the rainfall.

[0075] The subsequent adjustments can be made in the same way to realize the function of increasing the rainfall in sequence. The motor 53 rotates in the opposite direction, the driving shaft 52 performs the tape unwinding operation, and the driven shaft 51 performs the tape winding operation, so that the rainfall can be reduced in sequence.

[0076] In this embodiment, the diameter of the holes on the orifice plate 24 is the same as the diameter of the hole surface with the largest diameter. The adjustment belt 54 is arranged to fit the orifice plate 24 , and the orifice plate 24 can support the adjustment belt 54 .

[0077] The adjustment belt 54 may be a rubber belt, a leather belt or the like.

[0078] See also Figure 3 In this embodiment, the driven shaft 51 is rotatably mounted on the mounting frame 23 , a mounting plate 521 is symmetrically mounted on one side of the rain outlet box 21 away from the mounting frame 23 , and the driving shaft 52 is rotatably mounted on the mounting plate 521 .

[0079] The transmission member 55 can be a synchronous wheel and a synchronous belt, a belt and a pulley, a sprocket and a chain, a gear and a toothed belt, etc.

[0080] As another optional method of this embodiment, the rainfall regulating device 5 includes an adjusting plate and a horizontal moving device. The adjusting plate is provided with holes with different apertures. The adjusting plate passes through the rain outlet box 21, and the bottom is attached to the orifice plate 24. The horizontal moving device is installed on the rain outlet box 21 through a bracket. The horizontal moving device is used to drive the adjusting plate to move so that the holes of different diameters on the adjusting plate are aligned with the orifice plate 24 to achieve rainfall regulation.

[0081] See also Figure 4 As an optional method of this embodiment, the rainfall regulating device 5 also includes two guide rollers 56, and the two guide rollers 56 are rotatably arranged on both sides of the rain outlet box 21. The two guide rollers 56 are used to limit the two sides of the adjusting belt 54 so that the adjusting belt 54 fits the orifice plate 24.

[0082] By setting the guide rollers 56 to limit the two sides of the adjusting belt 54, the adjusting belt 54 can be set in close contact with the orifice plate 24 to avoid the upper side of the adjusting belt 54 abutting against the upper side walls of the strip openings 212 on both sides of the rain outlet box 21 when adjusting the orifice surface, causing greater wear.

[0083] See also Figure 4 and Figure 6 As a preferred embodiment of the present invention, the automatic driving safety test system for the intelligent networked vehicle further comprises a clamping assembly 7, wherein the clamping assembly 7 comprises a push cylinder 71 and a circular pressure plate 72, wherein the push cylinder 71 is mounted on the top of the rain outlet box 21, and the circular pressure plate 72 is arranged inside the rain outlet box 21, and the two sides of the circular pressure plate 72 correspond to the strip-shaped opening 212 passing through the two sides of the rain outlet box 21, and are correspondingly sleeved on the two side walls of the rain outlet box 21, and the strip-shaped opening 212 and the circular pressure plate 72 are clearance-matched.

[0084] By setting the clamping assembly 7, the adjusting belt 54 can be pressed against the orifice plate 24 through the circular pressure plate 72 to ensure that rainwater does not flow out through the gap between the adjusting belt 54 and the orifice plate 24; when adjusting the orifice surfaces of different diameters, the push cylinder 71 lifts the circular pressure plate 72 to separate the circular pressure plate 72 from the adjusting belt 54. Since the two sides of the adjusting belt 54 are limited by the guide rollers 56, the part of the adjusting belt 54 located in the strip opening 212 will not contact the circular pressure plate 72. Therefore, when adjusting the orifice surfaces of different diameters, the upper side of the adjusting belt 54 will not interact with the circular pressure plate 72 when moving, that is, no friction will be generated, making it easier to adjust the position of the adjusting belt 54 and extend the service life of the adjusting belt 54.

[0085] The push cylinder 71 can be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, etc., and the number of the push cylinders 71 is preferably two, which are installed on both sides of the top of the rain outlet box 21, and the output end thereof passes through the rain outlet box 21 and is connected to the circular pressure plate 72.

[0086] See also Figure 4 and Figure 6 A pair of sleeve plates 73 are installed on both sides of the circular pressure plate 72, and each pair of sleeve plates 73 includes two sleeve plates 73, and the two sleeve plates 73 are located on both sides of the strip opening 212 of the rain outlet box 21, so that the two sides of the circular pressure plate 72 are correspondingly sleeved on the two side walls of the rain outlet box 21, and the opposite sides of the pair of sleeve plates 73 are provided with sealing strips, which fit the side walls of the rain outlet box 21 to ensure sealing and prevent water in the rain outlet box 21 from flowing into the strip opening 212 and being discharged through the gap between the sleeve plates 73 and the side walls of the rain outlet box 21.

[0087] See also Figure 1 , Figure 3 and Figure 7 As a preferred embodiment of the present invention, the automatic driving safety test system for the intelligent networked vehicle further comprises a synchronization device 6, wherein the synchronization device 6 comprises a mounting box 61, a driving device 62, a clamping plate 63 and a trigger switch 64, wherein the mounting box 61 is mounted on the rain simulation device 2 and is arranged adjacent to the driving shaft 52, wherein the clamping plate 63 is slidably arranged inside the mounting box 61, wherein the trigger switch 64 is installed through one end of the mounting box 61, wherein the detection end of the trigger switch 64 faces the other end of the mounting box 61, and wherein the driving device 62 is used to lift the clamping plate 63;

[0088] The mobile obstacle 3 further includes a driving plate 34 , and the driving plate 34 is installed on the top end of the connecting rod 32 .

[0089] In this embodiment, when the mobile obstacle 3 and the test vehicle 1 are located in the same plane, the driving plate 34 is flush with the opening height of the installation box 61 and is higher than the clamping plate 63, and the center line of the driving plate 34 is flush with the height of the trigger switch 64; wherein the connecting rod 32 is preferably of a liftable and adjustable type, and when the road has a slope, it can be adjusted according to the slope.

[0090] By setting the installation box 61 on the front side of the rainwater simulation device 2, after gradually reducing the distance between the detection device 4 and the mobile obstacle 3, when the test vehicle 1 collides with the obstacle, since the rainwater simulation device 2 extends forward on the front side of the test vehicle 1, the installation box 61 will first act on the driving plate 34, and the driving plate 34 will be inserted into the interior of the installation box 61. When the driving plate 34 is inserted, the trigger switch 64 detects the driving plate 34, and the trigger switch 64 controls the driving device 62 to lift the clamping plate 63, and the clamping plate 63 clamps the driving plate 34. Therefore, when the test vehicle 1 collides with the mobile obstacle 3, the driving plate 34 can drive the entire mobile obstacle 3 to move together without colliding with it, thereby avoiding the mobile obstacle 3 being damaged by the test vehicle 1, and the mobile obstacle 3 can be used continuously.

[0091] Preferably, when the clamping plate 63 is lifted up and clamped, the clamping plate 63 simultaneously drives the driving trolley 31 to be lifted up and separated from the ground through the connecting rod 32, so that the mobile obstacle 3 can better move with the test vehicle 1.

[0092] Among them, multiple sliding rods are installed inside the installation box 61 and away from the opening side, and the clamping plate 63 is mounted on the sliding rod to form a sliding assembly, or multiple sliding grooves are opened on the inner wall of the installation box 61, and sliding blocks are correspondingly arranged on the clamping plate 63, and the sliding blocks slide into the sliding grooves to form a sliding assembly.

[0093] Among them, the installation box 61 is installed on the installation plate 521, and the length of the installation box 61 is greater than the width of the test vehicle 1, so that the mobile obstacle 3 is within the impact range of the test vehicle 1, which can ensure that the driving plate 34 in the mobile obstacle 3 can be clamped and assembled with the synchronization device 6.

[0094] Rubber blocks are provided at the bottom of the clamping plate 63 and the top of the inner wall of the installation box 61 to ensure stability during support. An elastic rubber block 612 is provided on the inner wall of the installation box 61 and away from the opening side. When the driving plate 34 interacts with the inner wall of the installation box 61, the elastic rubber block 612 can buffer the impact force of the driving plate 34.

[0095] The trigger switch 64 can be a photoelectric switch or a laser sensor, etc.

[0096] As an optional method of this embodiment, the driving device 62 is an electric push rod or a hydraulic cylinder or a pneumatic cylinder. The driving device 62 is installed on the top of the installation box 61, and the output end of the driving device 62 passes through the installation box 61 and is connected to the clamping plate 63.

[0097] As another optional mode of this embodiment, the driving device 62 includes a rotating member 621 and a connecting assembly, and the connecting assembly is transmission-connected between the rotating member 621 and the clamping plate 63 .

[0098] By setting the driving force of the driving device 62 to the rotating member 621, the output shaft of the rotating member 621 rotates a certain angle to drive the clamping plate 63 to lift the clamping driving plate 34 through the connecting component, so that the clamping driving plate 34 can be achieved more quickly.

[0100] like Figure 8 and Fig. 9 When the rotating member 621 drives the rotating plate 622 to rotate counterclockwise, the rotating plate 622 drives the driving shaft 623 to slide along the connecting frame 624 and drives the connecting frame 624 to move upward, and the connecting frame 624 drives the clamping plate 63 to lift the clamping driving plate 34.

[0101] In another embodiment, the connecting component is a telescopic rod, one end of which is fixedly connected to the output end of the rotating member 621 , and the other end of the telescopic rod passes through the rectangular hole 611 and is rotatably connected to the clamping plate 63 .

[0102] The elastic rubber block 612 is not provided at the position of the installation box 61 corresponding to the rectangular hole 611 .

The automatic driving safety testing system for the smart networked car also includes a connecting member 8, and the connecting member 8 includes a connecting frame 81, a positioning shaft 82 and an arc-shaped slider 83. One end of the connecting member 8 is connected to the circular pressure plate 72, and one end of the positioning shaft 82 is slidably installed on the other end of the connecting frame 81 through the arc-shaped slider 83. The other end of the positioning shaft 82 passes through the rotating member 621 and is inserted into the positioning hole 522.

[0104] When the rainfall amount is not adjusted, the positioning shaft 82 is inserted into the positioning hole 522. When the driving plate 34 is inserted into the interior of the installation box 61, the trigger switch 64 detects the driving plate 34 and controls the motor 53 to rotate counterclockwise at a preset angle. The motor 53 drives the rotating member 621 to rotate at a preset angle through the active shaft 52. The rotating member 621 drives the clamping plate 63 to clamp the driving plate 34 through the connecting assembly. Since the motor 53 only needs to drive the active shaft 52 to rotate at a preset angle, the adjustment amount of the adjusting belt 54 by the active shaft 52 and the driven shaft 51 is extremely small, and the adjustment of the adjusting belt 54 itself during this period does not affect the test of the test vehicle 1.

[0105] During the test, when adjusting the rainfall, the push cylinder 71 first lifts up the circular pressure plate 72 to prevent the upper side of the adjustment belt 54 from being rubbed during adjustment. When the push cylinder 71 is lifted up, the circular pressure plate 72 also drives the connecting frame 81 to follow up and the connecting frame 81 drives the positioning shaft 82 to move out of the positioning hole 522, so that when the subsequent motor 53 drives the active shaft 52 to adjust the adjustment belt 54, it will not drive the rotating part 621 to rotate with it; each time the adjustment belt 54 is adjusted, the positioning hole 522 faces the positioning shaft 82.

[0106] Therefore, the motor 53 and the driving shaft 52 can be used to adjust the position of the adjustment belt 54 to adjust the amount of rainfall, and can also drive the rotating member 621 to lift the clamping plate 63 to clamp the driving plate 34.

[0107] Among them, in this embodiment, two driving devices 62 are provided, and the two driving devices 62 are correspondingly provided on both sides of the installation box 61, and two rotating members 621 are respectively installed at both ends of the active shaft 52, so that the clamping plate 63 can be lifted from both sides of the clamping plate 63 to improve the stability of the lifted clamping plate 63, and two connecting members 8 are correspondingly provided.

[0108] The positioning shaft 82 is slidably connected to the connecting frame 81 through the arc-shaped slider 83, so that when the driving shaft 52 drives the rotating member 621 to rotate a preset angle through the positioning shaft 82, the positioning shaft 82 can move relative to the connecting frame 81;

[0109] The cross section of the arc-shaped slider 83 is set to be T-shaped, and the end of the connecting frame 81 is provided with an arc-shaped sliding groove of a corresponding shape, so that when the connecting frame 81 is raised or lowered, the positioning shaft 82 can be driven to follow the lifting or lowering.

[0110] As another optional mode of this embodiment, the rotating member 621 is configured as a rotating motor, which is mounted on the mounting box 61 via an assembly frame, and the rotating plate 622 or the telescopic rod is correspondingly mounted at the output end of the rotating motor.

[0111] In the present invention, the motor 53, the push cylinder 71, the water pump and the driving trolley 31 are preferably remotely controlled, and the control method includes setting a control handle for control, or downloading an APP for control through a terminal device such as a mobile phone, etc. After the remote control authorization, the trigger switch 64 can be used to control the start of the motor 53, and the detection device 4 can control the movement of the driving trolley 31.

[0112] The present invention also provides a method for testing the safety of automatic driving of an intelligent networked vehicle.

[0113] A method for testing the safety of autonomous driving of a smart networked car, using the system for testing the safety of autonomous driving of a smart networked car, comprises the following steps: S1, placing the moving obstacle 3 at a test intersection, placing the detection device 4 at one side of the test road, and at a preset distance from the moving obstacle 3;

[0114] S2, the test vehicle 1 travels along the test track at a preset speed. When the detection device 4 detects the test vehicle 1, the mobile obstacle 3 travels along the test intersection to detect whether the test vehicle 1 can safely pass through the test intersection;

[0115] S3, adjusting the distance between the detection device 4 and the moving obstacle 3, and then repeating the test operation of S2;

[0116] S4. Use the rain simulation device 2 to simulate rainy weather, and then repeat the test steps S1 to S3 to detect whether the test vehicle 1 can safely pass the test intersection.

[0117] When the rainwater simulation device 2 is used, the water pump inputs the water in the water tank into the rain outlet box 21 through the water pipe, and the water flows out through the hole surface of the regulating belt 54 and the orifice plate 24 in the rain outlet box 21 to form rainwater falling on the front of the test vehicle 1;

[0118] During the test, the rainfall can be increased in sequence to test the effect of different rainfall on the test vehicle 1. When adjusting, first align the hole surface with the smallest aperture with the orifice plate 24. At this time, the rainfall is the smallest. When increasing the rainfall, the motor 53 drives the driving shaft 52 to rotate clockwise. The driving shaft 52 drives the driven shaft 51 to rotate through the transmission member 55. The driven shaft 51 releases the adjustment belt 54 while the driving shaft 52 winds the adjustment belt 54, so that the hole surface with a larger diameter moves into the rain box 21 and is aligned with the orifice plate 24. The power of the water pump is adjusted to achieve the function of increasing the rainfall.

[0119] The subsequent adjustments can be made in the same way to realize the function of increasing the rainfall in sequence. The motor 53 rotates in the opposite direction, the driving shaft 52 performs the tape unwinding operation, and the driven shaft 51 performs the tape winding operation, so that the rainfall can be reduced in sequence.

[0120] At the same time, by setting the installation box 61 on the front side of the rainwater simulation device 2, after gradually reducing the distance between the detection device 4 and the mobile obstacle 3, when the test vehicle 1 collides with the obstacle, since the rainwater simulation device 2 extends forward on the front side of the test vehicle 1, the installation box 61 will first act on the driving plate 34, and the driving plate 34 will be inserted into the interior of the installation box 61. When the driving plate 34 is inserted, the trigger switch 64 detects the driving plate 34, and the trigger switch 64 controls the driving device 62 to lift the clamping plate 63, and the clamping plate 63 clamps the driving plate 34. Therefore, when the test vehicle 1 collides with the mobile obstacle 3, the driving plate 34 can drive the entire mobile obstacle 3 to move together without colliding with it, thereby avoiding the mobile obstacle 3 being damaged by the test vehicle 1, and the mobile obstacle 3 can be used continuously.

[0121] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
