[0038] Figure 11 is a structural diagram of a braking test system based on the Internet of Vehicles according to an embodiment of the present invention, wherein the braking test system 100 based on the Internet of Vehicles comprises: a test component 110, which is arranged on both sides of a test road, and is used to form different automatic braking test environments by changing its own operating state, so that the vehicle to be tested performs an automatic braking test under the automatic braking test environment; a test host computer 120, which is used to issue a test instruction to the vehicle to be tested to control the movement route and speed of the vehicle to be tested; a monitoring module 130, which is arranged on the vehicle to be tested, and is used to collect first motion state information of the vehicle to be tested before the test and second motion state information after the test, and transmit the first motion state information and the second motion state information to the cloud platform 160 through the communication module 150; an image acquisition module 140, which is arranged on one side or both sides of the test road, and is used to collect first position information of the vehicle to be tested before the test and second position information of the vehicle to be tested after the test The first position information and the second position information are transmitted to the cloud platform 160 through the communication module 150; the communication module 150 is used to realize data transmission between the monitoring module 130, the image acquisition module 140, the test controller 170, the test display 180 and the cloud platform 160; the cloud platform 160 is used to determine the test control information of the vehicle to be tested according to the first motion state information and the first position information, and transmit the test control information to the test controller 170 through the communication module 150, and determine the test result information of the vehicle to be tested according to the second motion state information and the second position information, and transmit the test result information to the test controller 170 and the test display 180 through the communication module 150; the test controller 170 is used to control the operating state of the test component 110 according to the test control information or the test result information; the test display 180 is used to display the test result information.

[0039] In a specific embodiment, the vehicle uses the AEB (Autonomous Emergency Braking) system to perform an automatic braking test. The AEB system measures the distance to the vehicle in front or an obstacle through sensing components (such as radar or camera), and then uses a data analysis module to compare the measured distance with the warning distance and the safety distance. If it is less than the warning distance, the system will automatically start to assist the driver in automatic braking, thereby reducing the probability of an accident.

[0040] In a specific embodiment, the test assembly 110 is positioned on either side of the test road and is configured to create different automatic braking test environments by varying its operating state, thereby enabling the vehicle under test to undergo an automatic braking test within these environments. Specifically, the test assembly 110 includes, for example, but is not limited to, elevating railings positioned on either side of the test road, and a simulated dummy that can move in different directions relative to the test road. By varying the elevating state of the railings, as well as the speed and direction of the simulated dummy's movement, various different automatic braking test environments can be created, enabling the vehicle under test to undergo an automatic braking test within these environments.

[0041] In a specific embodiment, the test host computer 120 issues test instructions to the test vehicle to control the test vehicle's movement route and speed. Specifically, the test host computer 120 uses a wireless communication connection (such as 5G communication) with the test vehicle to control the test vehicle's speed and initiate the test movement state. For example, the high-speed test vehicle is controlled to drive at 80 kph for the test, and the low-speed test vehicle is controlled to drive at 30 kph for the test, thereby controlling the high-speed and low-speed test vehicles to prevent false triggering of 3AEB.

[0042] In a specific embodiment, monitoring module 130 is disposed on the vehicle under test and is configured to collect first motion state information of the vehicle under test before the test and second motion state information of the vehicle under test after the test. Specifically, monitoring module 130 may collect deceleration information of the vehicle under test, thereby determining whether the vehicle under test performs effective emergency braking under different test conditions and whether the test passes, thereby facilitating reliable test results.

[0043] In a specific embodiment, the image acquisition module 140 is disposed on one or both sides of the test road and is used to collect first position information of the test vehicle before the test and second position information after the test. Specifically, the image acquisition module 140 includes, but is not limited to, a wide-angle visual sensor (e.g., a high-definition camera) that can be mounted above the test road poles, with a detection range of, for example, 500-1000 meters. The image acquisition module 140 can capture the position information of the test vehicle in real time over a wide angle range through continuous shooting or video streaming, thereby determining whether the test vehicle is in the target position for testing and the target position for test completion, thereby determining whether the test can be started and whether the test is complete, and facilitating monitoring of the test progress.

[0044] In a specific embodiment, the communication module 150 establishes and maintains communication links between various components, enabling data transmission between the monitoring module 130, the image acquisition module 140, the test controller 170, the test display 180, and the cloud platform 160. Specifically, it is understood that the communication module 150 is capable of not only transmitting data on the test vehicle (such as, but not limited to, the speed and position information of the test vehicle) and roadside data (such as, but not limited to, the status data of the test component 110) to the cloud platform 160, but also receiving command information sent from the cloud platform 160, thereby achieving two-way communication between different ports.

[0045] In a specific embodiment, the cloud platform 160 determines the test control information of the vehicle to be tested based on the first motion state information and the first position information, and transmits the test control information to the test controller 170 through the communication module 150, and determines the test result information of the vehicle to be tested based on the second motion state information and the second position information, and transmits the test result information to the test controller 170 and the test display 180 through the communication module 150. Specifically, after receiving the first motion state information and the first position information, the cloud platform 160 can use an advanced algorithm (such as a machine learning model or a rule engine) to analyze the first motion state information and the first position information to accurately determine whether the test start condition is met, thereby accurately obtaining the test control information of the vehicle to be tested; after receiving the second motion state information and the second position information, the cloud platform 160 can use an advanced algorithm (such as a machine learning model or a rule engine) to analyze the second motion state information and the second position information to accurately determine whether the test is passed, thereby accurately obtaining the test result information of the vehicle to be tested.

[0046] In a specific embodiment, the test controller 170 controls the operating state of the test component 110 based on the test control information or the test result information. Specifically, when the cloud platform 160 determines that the test start condition is met based on the first motion state information and the first position information and issues the test control information to the vehicle to be tested, the test controller 170 receives the test control information and controls the test component 110 to make corresponding operating state adjustments, thereby forming a corresponding test environment. When the cloud platform 160 determines that the test is completed based on the second motion state information and the second position information and issues the test result information to the vehicle to be tested, the test controller 170 receives the test control result and controls the test component 110 to make corresponding operating state adjustments, thereby restoring the corresponding test environment that has been formed to facilitate subsequent testing.

[0047] In a specific embodiment, the test result information is displayed on the test display 180. Specifically, the test display 180 is, for example, disposed above a pole in the test field, so that the test personnel can learn the test results in a timely manner.

[0048] Therefore, according to the braking test system 100 based on the Internet of Vehicles embodiment of the present invention, by combining the image testing component 110, the test host computer 120, the monitoring module 130, the image acquisition module 140, the communication module 150, the cloud platform 160, the test controller 170, the test display 180 and the Internet of Vehicles technology, the test control information of the vehicle to be tested can be determined according to the first motion state information and the first position information before the test, and the test result information of the vehicle to be tested can be determined according to the second motion state information and the second position information after the test. The test controller 170 controls the operating state of the test component 110 according to the test control information or the test result information to form different automatic braking test environments, and displays the test result information through the test display 180, so that the test personnel can understand the test results in a timely manner, thereby realizing the automated testing process of different scenarios and improving the utilization rate and test efficiency of the field test.

[0051] In a specific embodiment, the test vehicles include a first test vehicle traveling at a first preset speed and a second test vehicle traveling at a second preset speed, thereby satisfying automatic braking tests at different speeds, helping to increase test diversity. Furthermore, the first test vehicle and the second test vehicle can be tested simultaneously in different test areas, helping to improve test efficiency. Specifically, the first preset speed is set to 80 kph, for example, and the second preset speed is set to 30 kph, for example.

This creates different test environments and helps increase test diversity. Specifically, when testing is required, the guardrail in the corresponding test area can be raised and / or the corresponding obstacle can be controlled to move to create the corresponding test conditions. The obstacles are used to simulate different pedestrian movements on the road.

[0053] Specifically, according to an embodiment of the present invention, a braking test system 100 based on the Internet of Vehicles comprises a test road including a first straight test area, a second straight test area, a third straight test area, and a curved test area, which are sequentially connected.

Corresponding test control information and test result information are determined for different test areas, thereby improving the reliability and accuracy of the test. Specifically, the test result information includes test pass and test fail.

[0056] In a specific embodiment, the cloud platform 160 transmits the test control information and the test result information to the test host computer 120 via the communication module 150. The test host computer 120 determines the test instructions based on the test control information or the test result information to control the movement route and speed of the vehicle to be tested, thereby helping to improve the intelligence and efficiency of the test.

[0058] In one embodiment of the present invention, when determining the test control information of the vehicle to be tested based on the first motion state information and the first position information, and determining the test result information of the vehicle to be tested based on the second motion state information and the second position information, the cloud platform 160 is used to: when it is determined that the first vehicle to be tested is located at the first target position on the starting side of the first straight test area according to the first position information, determine the test control information of the first straight test area, and transmit the test control information of the first straight test area to the test controller 170 and the test host computer 120 through the communication module 150; and, when it is determined that the first vehicle to be tested is located at the second target position on the ending side of the first straight test area according to the second position information, and when it is determined that the deceleration of the first vehicle to be tested through the first straight test area is the first preset deceleration according to the second motion state information, determine the test result information of the first straight test area as passed; otherwise, determine the test result information of the first straight test area as failed, and transmit the test control information of the first straight test area to the test controller 170 and the test host computer 120 through the communication module 150. The test result information is transmitted to the test host computer 120, the test controller 170 and the test display 180; the test controller 170 is used to control the height of the first high-speed guardrail to rise to the first target height according to the test control information of the first straight test area; and, according to the test result information of the first straight test area, control the height of the first high-speed guardrail to fall to the initial height; the test host computer 120 is used to determine a first start test instruction according to the test control information of the first straight test area to control the first vehicle to be tested to depart from the first straight test area at a first preset speed; and, when it is determined that the test passes according to the test result information of the first straight test area, determine a first end test instruction to control the first vehicle to be tested to travel to the third target position located on the starting side of the second straight test area; or, when it is determined that the test fails according to the test result information of the first straight test area, determine an end test instruction to control the first vehicle to be tested to leave the test road; the test display 180 is used to display the test result information of the first straight test area.

The test host computer 120 determines a first start test instruction based on the test control information for the first straight test zone to control the first vehicle to be tested to depart from the first straight test zone at a first preset speed to perform an automatic braking test in the first straight test zone. Specifically, the first target height is, for example, 1.5 meters, and the first preset speed is, for example, 80 kph.

[0060] In a specific embodiment, since the first straight test zone is a straight road and only the first highway guardrail height is provided on the roadside of the first straight test zone, no braking conditions are required, the AEB system should not be triggered, and the vehicle should not brake. When the first vehicle under test is determined to be at the second target position at the end of the first straight test zone based on the second position information, and the deceleration of the first vehicle under test through the first straight test zone is determined to be a first preset deceleration based on the second motion state information, it indicates that the first vehicle under test has passed the automatic braking test of the first straight test zone.

[0061] In a specific embodiment, since the first straight test section is a straight road and only the first highway guardrail height is provided on the roadside of the first straight test section, no braking conditions are required, the AEB system should not be triggered, and the vehicle should not brake. If the first vehicle under test is determined not to be at the second target position at the end of the first straight test section based on the second position information, or if the deceleration of the first vehicle under test through the first straight test section is determined not to be the first preset deceleration based on the second motion state information, the first vehicle under test has failed the automatic braking test in the first straight test section. The cloud platform 160 determines test result information for the first straight test section.

The test display 180 displays the test result information for the first straight test section. Specifically, the first preset deceleration is 0.

[0062] Specifically, according to the braking test system 100 based on the Internet of Vehicles embodiment of the present invention, when conducting an automatic braking test on the first vehicle to be tested in the first straight test area, when the automatic braking test conditions of the first straight test area are met, the corresponding test component 110 is controlled to form a corresponding form, forming a corresponding test environment. When the automatic braking test in the first straight test area is completed, if it is judged that the test has passed, it automatically enters the second straight test area. If it is judged that the test has not passed, the first vehicle to be tested is controlled to leave the test road to end the test, thereby realizing the automated testing process of the first vehicle to be tested in the first straight test area, and improving the utilization rate and test efficiency of the site test.

[0063] In one embodiment of the present invention, when determining the test control information of the vehicle to be tested based on the first motion state information and the first position information, and determining the test result information of the vehicle to be tested based on the second motion state information and the second position information, the cloud platform 160 is used to: when it is determined that the first vehicle to be tested is located at the third target position on the starting side of the second straight test area according to the first position information, determine the second straight test area test control information, and transmit the second straight test area test control information to the test controller 170 and the test host computer 120 through the communication module 150; and, when it is determined that the first vehicle to be tested is located at the fourth target position on the ending side of the second straight test area according to the second position information, and when it is determined that the deceleration of the first vehicle to be tested through the second straight test area is the second preset deceleration according to the second motion state information, determine the second straight test area test result information as passed; otherwise, determine the second straight test area test result information as failed, and transmit the second straight test area test result information to the test host computer 120 and the test controller 170 through the communication module 150. and a test display 180; the test controller 170 is used to control the height of the second high-speed guardrail to be raised to the first target height according to the test control information of the second straight test area, and control the first test obstacle to move along the length direction of the second straight test area at a first preset moving speed; and, according to the test result information of the second straight test area, control the height of the second high-speed guardrail to be lowered to the initial height, and control the first test obstacle to return to the initial position; the test host computer 120 is used to determine a second start test instruction according to the test control information of the second straight test area to control the first vehicle to be tested to depart from the second straight test area at the first preset speed; and, when it is determined that the test passes according to the test result information of the second straight test area, determine a second end test instruction to control the first vehicle to be tested to travel to the fifth target position located on the starting side of the third straight test area; or, when it is determined that the test fails according to the test result information of the second straight test area, determine an end test instruction to control the first vehicle to be tested to leave the test road; the test display 180 is used to display the test result information of the second straight test area.

[0064] In a specific embodiment, when the first position information determines that the first vehicle to be tested is at the third target position on the starting side of the second straight test zone, it indicates that the automatic braking test conditions for the second straight test zone are met. The cloud platform 160 then determines the second straight test zone test control information. The test controller 170 controls the second highway guardrail to be raised to the first target height based on the second straight test zone test control information, and controls the first test obstacle to move along the length of the second straight test zone at a first preset speed, simulating pedestrian movement on the road and forming a test environment for the second straight test zone. The test host computer 120 then determines a second start test instruction based on the second straight test zone test control information, controlling the first vehicle to be tested to depart from the second straight test zone at the first preset speed to perform the automatic braking test in the second straight test zone. Specifically, the first target height is, for example, 1.5 meters, the first preset speed is, for example, 80 kph, and the first preset moving speed is, for example, 5 kph.

[0065] In a specific embodiment, since the second straight test area is a straight road, not only is a second high-speed guardrail set on the roadside of the second straight test area, but the first test obstacle is also controlled to move at a first preset moving speed along the length direction of the second straight test area to simulate pedestrians moving on the road. Therefore, there is a condition requiring braking, the AEB system should be triggered, and the vehicle should brake. When it is determined according to the second position information that the first vehicle to be tested is at the fourth target position on the end side of the second straight test area, and it is determined according to the second motion state information that the deceleration of the first vehicle to be tested passing through the second straight test area is the second preset deceleration, it is indicated that the first vehicle to be tested Through the automatic braking test in the second straight test zone, cloud platform 160 determines the test result information for the second straight test zone. Test controller 170 controls the second highway guardrail to be lowered to its initial height based on the test result information, facilitating subsequent testing. Test host computer 120 determines a second end-of-test instruction based on the test result information for the second straight test zone, controlling the first vehicle to be tested to travel to the fifth target position located at the starting side of the third straight test zone, thereby automatically entering the test in the third straight test zone. This helps improve testing efficiency. Test display 180 displays the test result information for the second straight test zone. Specifically, the second preset deceleration is 0.1g or less.

[0066] In a specific embodiment, since the second straight test area is a straight road, not only is a second high-speed guardrail set on the roadside of the second straight test area, but the first test obstacle is also controlled to move at a first preset moving speed along the length direction of the second straight test area to simulate pedestrians moving on the road. Therefore, there is a condition requiring braking, the AEB system should be triggered, and the vehicle should brake. When it is determined based on the second position information that the first vehicle to be tested is not located at the fourth target position on the end side of the second straight test area, or when it is determined based on the second motion state information that the deceleration of the first vehicle to be tested passing through the second straight test area is not the second preset speed, the vehicle to be tested is automatically braked. When the deceleration is set, it indicates that the first vehicle under test has failed the automatic braking test in the second straight test zone. Cloud platform 160 determines the test result information for the second straight test zone. Test controller 170 controls the second highway guardrail to be lowered to its initial height based on the test result information to facilitate subsequent testing. Test host computer 120 determines an end-of-test instruction based on the test result information for the second straight test zone, controlling the first vehicle under test to exit the test road, thereby terminating the test and improving test efficiency. Test display 180 displays the test result information for the second straight test zone. Specifically, the second preset deceleration is 0.1g or less.

[0067] Specifically, according to the vehicle networking-based braking test system 100 of an embodiment of the present invention, when conducting an automatic braking test on a first vehicle to be tested in a second straight-line test area, when the automatic braking test conditions of the second straight-line test area are met, the corresponding test component 110 is controlled to form a corresponding shape, forming a corresponding test environment. After the automatic braking test in the second straight-line test area is completed, if the test is judged to have passed, the vehicle automatically enters the third straight-line test area.

[0092] Specifically, according to the vehicle networking-based braking test system 100 of an embodiment of the present invention, when conducting an automatic braking test on the second vehicle to be tested in the third straight test area, when the automatic braking test conditions of the third straight test area are met, the corresponding test component 110 is controlled to form a corresponding form, forming a corresponding test environment. After the automatic braking test in the third straight test area is completed, if it is determined that the test has passed, the vehicle automatically enters the curve test area. If it is determined that the test has failed, the vehicle to be tested is controlled to leave the test road to end the test, thereby realizing an automated testing process for the second vehicle to be tested in the third straight test area and improving the utilization rate and efficiency of the field test.

[0093] In one embodiment of the present invention, when determining the test control information of the vehicle to be tested based on the first motion state information and the first position information, and determining the test result information of the vehicle to be tested based on the second motion state information and the second position information, the cloud platform 160 is used to: when it is determined that the second vehicle to be tested is located at the seventh target position on the starting side of the curve test area according to the first position information, determine the curve test area test control information, and transmit the curve test area test control information to the test controller 170 and the test host computer 120 through the communication module 150; and, when it is determined that the second vehicle to be tested is located at the eighth target position on the ending side of the curve test area according to the second position information, and when it is determined that the deceleration of the second vehicle to be tested through the curve test area is the eighth preset deceleration according to the second motion state information, determine the curve test area test result information as passing If the test result information of the curve test area is passed, otherwise it is determined that the test result information of the curve test area is failed, and the test result information of the curve test area is transmitted to the test host computer 120, the test controller 170 and the test display 180 through the communication module 150; the test controller 170 is used to control the fourth low-speed guardrail height to be raised to the second target height according to the curve test area test control information; and, according to the curve test area test result information, control the fourth low-speed guardrail height to be lowered to the initial height; the test host computer 120 is used to determine the fourth start test instruction according to the curve test area test control information to control the second vehicle to be tested to depart from the curve test area at a second preset speed; and, according to the curve test area test result, determine the end test instruction to control the second vehicle to be tested to leave the test road; the test display 180 is used to display the curve test area test result information.

[0094] In a specific embodiment, when the second vehicle to be tested is determined to be at the seventh target position on the starting side of the curve test zone based on the first position information, it indicates that the automatic braking test conditions for the curve test zone are met. The cloud platform 160 determines the curve test zone test control information. The test controller 170 controls the height of the fourth low-speed guardrail to be raised to the second target height based on the curve test zone test control information, thereby forming a test environment for the curve test zone. The test host computer 120 determines the fourth start test instruction based on the curve test zone test control information to control the second vehicle to be tested to depart from the curve straight test zone at a second preset speed to perform the automatic braking test in the curve test zone. Specifically, the second target height is, for example, 1 meter, and the second preset speed is, for example, 30 kph.

[0095] In a specific embodiment, since the curve test zone is a curve, braking conditions exist, triggering the AEB system and requiring the vehicle to brake. When the second position information determines that the second vehicle under test is at the eighth target position at the end of the curve test zone, and the second motion state information determines that the second vehicle under test's deceleration while passing through the curve test zone is at an eighth preset deceleration, this indicates that the second vehicle under test has undergone an automatic braking test while passing through the curve test zone. The cloud platform 160 determines test result information for the curve test zone. The test controller 170 controls the fourth low-speed guardrail to lower to its initial height based on the curve test zone test result information to facilitate subsequent testing. The test host computer 120 determines an end-of-test instruction based on the curve test zone test result information, controlling the second vehicle under test to exit the test road, thereby concluding the test. The test display 180 displays the curve test zone test result information. Specifically, the eighth preset deceleration is 0.2g or less.

[0096] In a specific embodiment, since the curve test zone is a curve, braking conditions exist, triggering the AEB system and requiring the vehicle to brake. If the second position information determines that the second vehicle under test is not located at the eighth target position at the end of the curve test zone, or if the second motion state information determines that the second vehicle under test's deceleration through the curve test zone is not the eighth preset deceleration, the second vehicle under test has failed the automatic braking test in the curve test zone. The cloud platform 160 determines curve test zone test result information, and the test controller 170 controls the fourth low-speed guardrail to lower to its initial height based on the curve test zone test result information to facilitate subsequent testing. The test host computer 120 determines an end-of-test instruction based on the curve test result information, directing the second vehicle under test to exit the test road, thereby concluding the test. The test display 180 displays the curve test zone test result information. Specifically, the eighth preset deceleration is 0.2g or less.

[0097] Specifically, according to the braking test system 100 based on the Internet of Vehicles embodiment of the present invention, when conducting an automatic braking test on the second vehicle to be tested in a curve test area, when the automatic braking test conditions of the curve test area are met, the corresponding test component 110 is controlled to form a corresponding form and a corresponding test environment. When the automatic braking test in the curve test area is completed, the second vehicle to be tested is controlled to leave the test road to end the test, thereby realizing an automated testing process for the second vehicle to be tested in the curve test area and improving the utilization rate and test efficiency of the site test.

[0114] In this specific embodiment, the RSU5 is tested, and the deceleration a of the XBR signal fed back by the vehicle AEB system 7 sent by the vehicle-mounted OBU6 is transmitted to the cloud platform 4 for the cloud platform 4 to judge the test instruction.

[0115] In this specific embodiment, the onboard OBU 6 receives the deceleration a information of the XBR signal fed back by the AEB system 7 of the test vehicle and transmits it to the test RSU 5 .

[0116] In this specific embodiment, the AEB system 7 is arranged at the front end of the test vehicle's front guardrail, and is used for single-lane guardrail and dummy AEB false triggering tests, and sends the vehicle's XBR deceleration a information to the on-board OBU 6, and transmits it to the cloud platform 4 for test passing judgment.

It can be raised out of the ground for testing under the action of the drive motor 9, and can also be lowered back to the ground under the action of the drive motor 9.

[0124] In this specific embodiment, the high / low speed curve guardrail 15 can be raised out of the ground for testing under the action of the drive motor 9, and can also be lowered back to the ground under the action of the drive motor 9.

[0125] In this specific embodiment, the test display screen 16 is arranged above the pole of the AEB test field, receives the test result feedback sent by the cloud platform 4, and displays it on the display screen.

[0126] In this specific embodiment, the test area 17 is divided into four areas from low to high according to the difficulty of the AEB test: the first test area, with a length of 500m, is used for the AEB function test of high- and low-speed single-sided guardrails; the second test area, with a length of 500m, is used for the AEB function test of high- and low-speed single-sided guardrails and pedestrians traveling longitudinally; the third test area, with a length of 500m, is used for the AEB function test of high- and low-speed single-sided guardrails and pedestrians traveling horizontally; the fourth test area, the curve test area, has an inner curve radius of 250m and an outer curve radius of 500m, and is used for the AEB function test of high- and low-speed single-sided curve guardrails.

[0127] In combination with the above, it can be seen that the braking test system based on the Internet of Vehicles of this specific embodiment can simultaneously conduct false triggering tests of single-side guardrails and pedestrians in high and low speed scenarios in one test area. The speed difference between high and low vehicle speeds is used to control the lifting and lowering of high and low speed test devices at different times, so that high and low speed vehicles can be tested simultaneously without affecting each other. Four test areas are set according to the difficulty of AEB false triggering. Using cloud platform technology, the vehicle test pass status is judged according to the information collected by the roadside camera and the deceleration information sent by the vehicle-side XBR, and the test device control instructions of the test area are issued according to the pass status, and the test results are displayed on the test display screen, realizing the automated test process of high and low speed scenarios, improving the site test utilization rate and test efficiency, and realizing the AEB false triggering test process integrated with vehicle, road and cloud.
