Methods and systems for end of line full vehicle automatic transmission quick bed-in procedure

摘要

Featured is are methods and systems for bedding-in an automatic transmission of a vehicle prior to delivery of the vehicle to an end customer. Such a bedding-in method is performed so as to reduce the occurrence of shifting problems or concerns occurring during the initial stages of ownership of the vehicle. More particularly, such a bedding-in method includes providing an automatic transmission having a controller that is configured to measure and learn about powertrain variation(s) and configured to adapt one or more operational parameters associated with shifting of the automatic transmission. Such a method also includes operating the vehicle according to a predetermined protocol before the vehicle reaches an end customer. Such a protocol being established so the transmission controller can learn about powertrain variations and adapt operation of the transmission to minimize effects on shifting of the transmission.

1. A method for begging-in an automatic transmission of a vehicle prior to delivery of the vehicle to an end customer, said bedding-in method comprising the steps of:
providing an automatic transmission having a controller that is configured to measure and learn about transmission variations while the engine is running and configured to adapt one or more operational parameters associated with shifting of the automatic transmission responsive to the measured and learned transmission variations; and operating the vehicle according to a predetermined protocol before the vehicle reaches an end customer, the protocol being established so that the transmission controller learns about powertrain variations and adapts operation of the transmission to minimize effects on shifting of the transmission, wherein said operating the vehicle includes static operating where the vehicle or wheels of the vehicle are not in motion and where the predetermined protocol is performed while said vehicle is statically operated, wherein during said static operation of the motor vehicle, the automatic transmission is shifted between a neutral transmission position to a drive transmission position a plurality of times and there is at least 3 seconds between each shift.
