Verfahren zum Herunterschalten automatischer Getriebe mit zwei Zwischenschritten.
摘要
An improved control method for properly coordinating a double transition downshift. The state changes of the various clutches of the transmission are sequenced in relation to a dynamic measure of the transmission speed ratio so as to provide consistent high quality shifting. Adaptive pressure controls are employed in conjunction with the sequencing to compensate for variability. <IMAGE>
