Patent number: 11421779Abstract: A vehicle transmission can perform predictive shifting. Road grade and vehicle path data can be employed to identify a future change in road grade such as a hill. A change in speed relative to a vehicle cruise speed can be estimated or predicted in view of the change in road grade and a current gear. If the change of speed is determined to be outside a performance bound, shift recommendation can be determined to maintain vehicle cruise speed within the performance bound. A controller can alter default gear selection of the transmission in response to receipt of the shift recommendation.Type: GrantFiled: July 28, 2020Date of Patent: August 23, 2022Assignee: EATON CUMMINS AUTOMATED TRANSMISSION TECHNOLOGIES, LLCInventors: Sujay Kawale, Eric R.
