In order to accurately evaluate and verify the function and reliability of low-speed parking of automobile active safety systems, tests in various complex scenarios are required. Roadblock targets are important elements in the test, and their design and performance directly affect the accuracy and reliability of the test results.

[0003] At present, common roadblock targets have certain limitations in shape, material and structure, and cannot meet the testing requirements of the vehicle active safety system in the low-speed parking state. For example, the shapes of some roadblock targets are not regular enough, the materials of the roadblock targets are not strong and durable enough, the structural design of the roadblock targets is unreasonable, and the installation and disassembly are inconvenient, which increases the cost and time of the test. When the test vehicle collides with the target object, the target object moves or falls over, causing additional damage to the test vehicle, resulting in lower safety and accuracy of the test.
