Description

Technical Field

[0001] This utility model relates to the field of truck rear-end targets that can be quickly retracted for vehicle testing, specifically a truck rear-end target that can be quickly retracted for vehicle testing. Background Technology

[0002] In modern automotive testing, especially during crash tests or driver assistance system testing, simulating various real-world road conditions is crucial. This typically involves using different types of vehicles as lead or follow vehicles, with trucks being particularly important in certain test scenarios due to their size and shape. However, existing target fixing methods are often complex and time-consuming, making it difficult to meet the needs of frequent changes and adjustments. Therefore, this invention provides a rapidly deployable truck rear target for automotive testing to solve the aforementioned problems.

[0003] Currently, existing rear-end targets on automotive test trucks cannot be reinstalled within a very short time after a collision during vehicle measurement, nor can they provide additional protection for the testing equipment. This increases the potential for collision damage and reduces safety during testing. Furthermore, existing rear-end targets on automotive test trucks are unsuitable for nighttime testing and fail to meet the requirements of intelligent driving systems for sensor recognition using lasers, millimeter-wave radars, and far-infrared vision.
