Abstract

This report provides an overview of the AEBS Soft Target project delivered to Daimler Trucks North Amer- ica as part of the 2016-2017 Mechanical Engineering Senior Design class at California Polytechnic State University, San Luis Obispo. The purpose was to build a soft target to test Advanced Emergency Braking Systems, or AEBS, on Daimler 0 s large trucks. Though this design is for Daimler specifically, there may be other interested parties such as highway safety groups and rival auto manufacturers. Currently, there are no suitable alternative products that satisfy every requirement for Daimler to validate their systems. They require a target that must not damage their trucks, visible to their sensor systems, mountable to a moving frame, can be reset quickly, and is a cheaper long term testing solution than their current setup.

The team was able to build a target that had improved car profile and appearance compared to preexisting targets while producing the target for a very low cost. The truss, bumpers, and tarp proved durable in Cal Poly’s testing environment. However, the base connections are a weak point of the design and failed when run over in testing. Fortunately these pieces are extremely quick and inexpensive to replace. Further full scale testing would better validate these results for truck impact.
