US 11,726,005 B2 · Pressure controlled auto braking for dynamic vehicle test (DVT)

Abstract

In accordance with exemplary embodiments, methods and systems are provided for automatically controlling braking of a vehicle during testing. In an exemplary embodiments, a testing assembly is provided that includes a roll test machine and a tester system. The roll test machine includes a flat surface, a plurality of rollers, and one or more optical controllers. The plurality of rollers are configured to engage a vehicle on the flat surface for testing of the vehicle. The one or more optical encoders are configured to generate wheel speed and brake force data for the vehicle during testing of the vehicle. The tester system includes a processor configured to at least facilitate generating instructions for brake pressure to be applied via a braking system of the vehicle during the testing of the vehicle.
