摘要: A computer system (100) (e.g., an on-board vehicle system) creates or updates a mapping of transmission gears and respective driveline ratios during operation the vehicle. The obtains (210, 220) current engine speed calculates (230) ratio for based on speed. If (240) is engaged, (250) at least in part ratio. Performing update may include adding (350) new gear updating (340) existing mapping, removing (360) duplicate from mapping. Applications cruise control, predictive shifting, selecting specific purpose descending hill).
