METHOD FOR CONTROLLING A TRANSMISSION COUPLED TO AN ENGINE THAT MAY BE AUTOMATICALLY STOPPED

摘要

Methods and systems for controlling a transmission coupled to an engine during an engine start are presented. In one example, a method adjusts a transmission tie-up force in response to an indication of transmission slip. The method may improve vehicle launch for stop/start vehicles.

1. A method for controlling a transmission coupled to an engine during an engine start, comprising:
applying a first pressure to a clutch tying a transmission input shaft to a transmission case during a first engine start; and applying a second pressure to the clutch tying the transmission input shaft to the transmission case during a second engine start, where the clutch tying the transmission input shaft to the transmission case is a gear clutch, and where the first pressure is different than the second pressure, and further comprising where an amount of the first pressure is adjusted to provide the second pressure.
