Publication number: 20200399937Abstract: A latching mechanism releasably engages a striker. The latching mechanism includes a housing secured to the vehicle body, and defining a striker channel through which the striker is selectively movable along a striker path. The latching mechanism includes a release lever pivotally connected to the housing and configured to rotate in a first direction in response to a tensile force. A detent is pivotally connected to the housing and to the release lever, and is movable with lost motion relative to the release lever. A fork bolt is adjustably connected to the housing and movable between a fully latched position, where the fork bolt fixes the striker relative to the housing, and a secondary position, where the striker is movable relative to the housing. Moving the fork bolt from the secondary position to the fully latched position causes the lost motion between the detent and the release lever.Type: ApplicationFiled: June 18, 2019Publication date: December 24, 2020Applicants: GM GLOBAL TECHNOLOGY OPERATIONS LLC, PyeongHwa Automotive Co., Ltd.Inventors: James N.

Publication number: 20200391721Abstract: Presented are model predictive control (MPC) systems, methods, and devices for regulating operation of hybrid powertrains. A method of controlling a hybrid powertrain includes a controller determining path plan data, including a vehicle origin, destination, and predicted path. Based on this path plan data, the controller estimates vehicle velocities for multiple rolling road segments of the predicted path and, based on the estimated velocities, determines an estimated power request—transmission input torque and/or vehicle axle torque—for each road segment. The controller calculates a minimum cost function such that total fuel consumption to generate the engine power output is minimized. Minimizing the cost function is subject to battery pack current limits and state of charge (SOC) terminal costs at the ends of the rolling road segments. Command signals are sent to the engine and motor to output engine and motor torque based on the calculated minimum cost function.Type: ApplicationFiled: June 14, 2019Publication date: December 17, 2020Applicants: GM GLOBAL TECHNOLOGY OPERATIONS LLC, Ohio State Innovation FoundationInventors: Yue-Yun Wang, Yuxing Liu, Marcello Canova
