To continue to develop and ultimately pilot test RTDBA technology on commercial motor vehicles (CMVs) and transfer brake performance data using CMV telematics technology.
Brake pressure, deceleration, and stopping distance for various weights of CMVs have been gathered with various levels of full or degraded brake performance. The U.S. Department of Energy (DOE) and Oak Ridge National Laboratory (ORNL) have utilized the data to develop a set of algorithms that should be able to determine the braking performance capability of a CMV by looking at real-time brake pressure and deceleration of a CMV. This information can be made available to the vehicle’s J1939 vehicle bus and could be transmitted electronically. Electronically collected brake performance data would offer important information from each CMV, potentially reducing or eliminating the need for a physical roadside inspection, and assist in informing drivers and fleets as to whether the CMV is suitable for safe truck platooning.
In this effort, researchers will pilot test the RTDBA technology on a small set of CMVs to validate the brake performance algorithm and prototype the electronic transfer of actual vehicle brake performance data.
