Patent number: 10960884Abstract: A system, method, and apparatus include a controller structured to predict a change in speed of a vehicle in advance of upcoming terrain and inhibit a coasting event if the speed exceeds a limit. In one form a velocity of the vehicle is predicted using a physics based model of the vehicle within a look ahead window in front of a vehicle. Such a look ahead window can be distance or time based. In another, speed of a vehicle is monitored during a coasting event and is compared against a threshold to determine whether to remain coasting or re-engage an engine to a driveline. The threshold is a function of road grade, and permits a larger deviation from set speed at low grade than at high grade. The function can be based on road grade and vehicle weight.Type: GrantFiled: June 11, 2020Date of Patent: March 30, 2021Assignee: Cummins Inc.Inventors: Oruganti Prashanth Sharma, Kenneth M. Follen, Tejas Shrikant Kinjawadekar, Vivek Anand Sujan, Daniel Reed Dempsey, Apurva Chunodkar, Nathanael G. Long, Jairo Andres Sandoval Leon

Patent number: 10935127Abstract: A control system, apparatus, and method integrates vehicle speed management and predicted gear shifting of a vehicle by determining current and future engine power requirements from the current and forward-looking route conditions to improve performance, drivability, and/or fuel economy of the vehicle over what is achievable through conventional gear state selection via static calibration tables and conventional shifting strategies. The selection of the vehicle reference speed is responsive to a gear selection to provide increased fuel economy, decreased trip time or combinations thereof.Type: GrantFiled: July 22, 2019Date of Patent: March 2, 2021Assignee: Cummins Inc.Inventors: Apurva A. Chunodkar, Zachary A. Knutson, Kenneth M. Follen, Vivek A. Sujan
