Generalized Adaptation of an Electric-Hydraulic hybrid drive system

James Long Steve Edgeman , Xin Wang
KersTech Vehicle Systems is in the process of creating a hybrid drive system combining a flat format hydraulic motor with an electric motor for energy recapture of vehicle momentum. The initial drive system is targeted at a specific vehicle application. A main component of the drive system being developed is a controller and the associated algorithm. The controller algorithm is a new adaptation of an optimally robust algorithm for model uncertainties and resilience against control feedback gain… Read More

ODOT Understanding Pedestrian Injuries and Social Equity

Nathan McNeil
Portland State University partnered with the project PI Josh Roll of the Oregon Department of Transportation on a two-phase research project examining pedestrian injury and social equity. Past research and planning has highlighted the existence of pedestrian injury disparities throughout the US and some local agencies have performed cursory analysis in Oregon. However, no statewide analysis of pedestrian injuries in Oregon has been completed to see how these injury outcomes differ by race and… Read More
