Title:
【発明の名称】自動車の操作方法
Document Type and Number:
Japanese Patent JP2752060
Kind Code:
B2
Abstract:
A control method is provided for the torque-establishing devices (28 to 32) of a motor vehicle multiple speed-ratio automatic transmission (l4) that is connected to the engine (l2) of the vehicle by way of a fluid coupling (24), particularly in so-called step-out situations, in which an upshift is commanded in response to a rapid decrease in the engine throttle position. When step-out situations likely to produce a sharp reversal in the polarity of torque carried by the transmission input shaft (42) are identified, an activated torque-establishing device is de-activated at a time determined in relation to the speed ratio across the fluid coupling, thereby avoiding transmission gear lash-related output torque disturbances due to the torque reversal.
