Synchronization point detection method for automatic gearbox uses monitored parameters of actuator for automatic gearbox

摘要

The method monitors at least one operating parameter of an actuator (17) for the automatic gearbox (14), e.g. the operating force per unit displacement of an electromagnetic actuator or the rise in the actuator operating force, for detecting the synchronization point. Also included are Independent claims for the following: (a) a control device for determining the synchronization point in an automatic gearbox; (b) a memory device for a program for detecting the synchronization point in an automatic gearbox; (c) a computer program product for detecting the synchronization point in an automatic gearbox; (d) an automobile drive train with an IC engine and an automatic gearbox
