AI Technical Summary

Technical Problem

The existing test dummies used for pedestrian collision testing of vehicle automatic emergency braking systems cannot be counterweighted, which makes the test significantly affected by different testing environments. In particular, they cannot drive stably in windy weather, which affects the testing efficiency.

Method used

A test dummy was designed, comprising a base, leg structure, and torso structure. It is equipped with a counterweight channel and a counterweight groove. The counterweight enters the counterweight channel through the counterweight inlet and moves to the groove, increasing the overall weight of the test dummy. It is equipped with a test slide rail and a drive motor. Combined with a weather sensor and controller, automatic counterweighting is achieved to ensure the stability of testing in different environments.

Benefits of technology

By using counterweights, the impact of environmental factors on the test was reduced, ensuring the stability and efficiency of pedestrian collision tests of the vehicle's automatic emergency braking system under different test environments, and improving the reliability of the test.

Abstract

This invention discloses a test dummy and a pedestrian collision testing system for vehicle automatic emergency braking systems. The test dummy for pedestrian collision testing of vehicle automatic emergency braking systems includes a dummy body. The dummy body includes a base, leg structures, and a torso structure. The leg structures are connected to the base along the height direction of the dummy body, and the torso structure is connected to the leg structures along the height direction. Each leg has a counterweight channel extending along the height direction. Counterweight block grooves are distributed at intervals along the height direction in the counterweight channels of each leg and the torso structure. The base has a counterweight block inlet that communicates with the counterweight channels, allowing the counterweight blocks to be aligned with the target counterweight block grooves. This test dummy can be calibrated using counterweight blocks, ensuring successful pedestrian collision testing of vehicle automatic emergency braking systems under different testing environments and improving testing efficiency.
