SYSTEM AND METHOD FOR CONTROLLING A TRANSMISSION

摘要

A system for operating a vehicle equipped with an automatic transmission and a vehicle road speed limiter (RSL) which is programmable to limit the maximum vehicle speed for a given transmission gear includes at least on controller. The at least one controller is operable, when the speed limiter (RSL) is active, to determine if the vehicle is operating in a shuttle shifting range based on the current status of preselected operating parameters. When the vehicle is operating in a shuttle shifting range, the at least one controller is operable to control transmission operation to prevent shifting under conditions where shifting would otherwise normally occur.

1. A method of operating a vehicle equipped with an automatic transmission and a vehicle road speed limiter (RSL) which is programmable to limit the maximum vehicle speed, the method comprising:
determining, when RSL is active, whether or not the vehicle is operating in a shuttle shifting range based on the current status of preselected operating parameters; and if the vehicle is operating in a shuttle shifting range, controlling transmission operation to prevent shifting under conditions where shifting would otherwise normally occur.
