Torque converter bypass clutch assembly determines desired clutch slip by multiplying actual slip by a factor less than unity

摘要: The assembly comprises an electronically operated valve means responsive to electronic processor performing repeated control loops. During each loop in a clutch slipping mode desired bypass slip is determined by multiplying the actual factor less than unity such that decreases until it equals target evaluated for particular set of operating conditions. After has reached hardlock established whereby torque flow through converter completely bypassed.
