Patent number: 11718298Abstract: The enclosed disclosure relates to hybrid vehicles and systems with an engine, a drivetrain with a clutch and a transmission, an electric machine, and a controller. The controller receives lookahead information within a lookahead window and present state information of the hybrid vehicle. The controller determines a predicted coasting opportunity exceeding a predetermined threshold within the lookahead window and determines a cruise control reference speed, a power split between the engine and the electric machine, and a timing of enabling engine-off coasting during the coasting opportunity. The controller deactivates the engine and disengages the clutch at a start of the coasting opportunity when the engine-off coasting is enabled.Type: GrantFiled: October 21, 2020Date of Patent: August 8, 2023Assignee: Cummins Inc.Inventors: Rohinish Gupta, Jonathan A. Dickson, Kenneth M. Follen, Apurva Arvind Chunodkar, Arun Prakash Thunga Gopal, Manik Narula

Publication number: 20220363238Abstract: Methods and systems for a powertrain power management in a vehicle with an electric motor, and an engine are disclosed. The methods and systems involve a powertrain that is operatively coupled to the engine and the electric motor, and an optimizer module operatively coupled to the powertrain. The optimizer module receives an operator information to travel a route from a remote management module, receives current route information for the route from a mapping application in response to the operator information, measures current vehicle status information for the hybrid vehicle, and decides a power management strategy for the vehicle based on the current route information and the current vehicle status information.Type: ApplicationFiled: November 6, 2019Publication date: November 17, 2022Inventors: Ke Li, Kenneth M. Follen, Anant Puri, John P. Kresse, III, Apurva Arvind Chunodkar

Patent number: 11396300Abstract: Disclosed are various techniques to optimize load delivery management of multiple vehicles along route. The optimization can involve evaluating vehicle-in-front information along with look ahead data to determine a recommended speed target and/or idle stop times and durations. The optimization can also involve determining bottleneck conditions from one or more vehicles and/or one or more infrastructure conditions and providing one or more recommended actions in response thereto.Type: GrantFiled: June 5, 2019Date of Patent: July 26, 2022Assignee: Cummins Inc.Inventors: Archit N. Koti, Jairo Andres Sandoval Leon, Vivek Anand Sujan, Patrick J. Shook, Apurva Arvind Chunodkar, Kenneth M. Follen

Patent number: 11046309Abstract: One embodiment is a method of operating an electronic control system (ECS) to control an engine to propel a vehicle. The method comprises receiving a throttle command, determining an operation to increase engine cycle efficiency by reducing engine torque below a magnitude corresponding to the throttle command and below a torque curve limit over a first vehicle operation segment and permitting an increase in engine torque above the torque curve limit over a second vehicle operation segment, controlling the engine to output torque below the magnitude corresponding to the throttle command and below the torque curve limit over the first vehicle operation segment, and controlling the engine to output torque above the torque curve limit over the second vehicle operation segment in response to a second received throttle command and constrained by an extended limit on operation of the engine above the torque curve limit.Type: GrantFiled: October 24, 2017Date of Patent: June 29, 2021Assignee: Cummins Inc.Inventors: Apurva Arvind Chunodkar, Kenneth M. Follen, Mugdha S. Sane, Srinivas Chakravarthy Bathula, Arun Prakash Thunga Gopal, Vivek A. Sujan
