Patent number: 10948074Abstract: A method of shifting an automated transmission in a vehicle comprises tracking vehicle parameters and determining a current gear selection. An upshift threshold can be determined for the current gear selection. Future gradient conditions are determined in a lookahead distance and are processed to determine a first percentage of future conditions that are above a selected gradient threshold. The first percentage of future conditions is compared to a selected first percentage limit to determine that the first percentage of future conditions is within the first percentage limit. The upshift threshold for the current gear selection is adjusted to change the vehicle parameter at which the vehicle transmission shifts from the current gear selection to the adjacent gear. The automated transmission is computer-controlled to shift to the adjacent gear according to the adjusted upshift threshold. A downshift threshold can also be adjusted.Type: GrantFiled: April 7, 2017Date of Patent: March 16, 2021Assignee: Eaton Cummins Automated Transmission Technologies, LLCInventors: Charles Adam Ganske, Himanshu Singh, Jerome J Palazzolo

Patent number: 10689001Abstract: A method of controlling a dual clutch transmission power on up shift including an on-coming clutch and an off-going clutch. The method includes implementing a prep phase comprised of decreasing torque on the off-going clutch, monitoring the off-going clutch speed to determine a slip point, and adding a bump torque to the off-going clutch when the off-going clutch reaches the slip point. The method implements a torque phase transferring torque from the off-going clutch to the on-coming clutch by increasing torque on the on-coming clutch towards an engine torque, decreasing torque on the off-going clutch, and simultaneously keeping the combination of torques greater than the slip point.Type: GrantFiled: August 31, 2018Date of Patent: June 23, 2020Assignee: Eaton Cummins Automated Transmission Technologies LLCInventors: Jeffrey S.
