Abstract:
The present disclosure provides a method for an intelligent quick bed-in of an automatic transmission comprising the steps of operating the vehicle according to a predetermined protocol so that the powertrain controller can learn about powertrain variations and adapt operation of the transmission; obtaining feedback information regarding operator performance of the method and vehicle performance during the method; determining whether the bed-in method was successful by the level of run-up or tie-up, by whether the powertrain controller was allowed to adapt, or by the level of powertrain controller adaptation; and completing the bedding-in process. The method being capable of reducing the time required for a bedding-in process, while improving the reliability of the bedding-in process.
