Abstract:
1. A method for controlling operational sequencing in an automatic transmission ( 102 ) of an auxiliary design, with at least one input drive shaft ( 110 ) and at least one output drive shaft ( 112 ), and including on the input and the output drive shafts ( 110 , 112 ) rotationally supported idler gears ( 130 , 132 ) and fixed gears which serve for formation of gear stages when meshed with one another in tooth engagement, with at least one sliding collar ( 126 ) which is axially slidable and fixed to a transmission shaft ( 128 ), adjacent at least one idler gear ( 130 , 132 ) and can be axially movable toward the idler gear ( 130 , 132 ) by an actuator apparatus ( 118 , 120 , 122 ) so that a toothing engagement of the sliding collar ( 126 ) with a come-along toothing of the idler gear ( 130 , 132 ) meshes, control of the actuator apparatus ( 118 , 120 , 122 ) for moving the sliding collar ( 126 ) is effected by a regulating component of a control center ( 136 ), control action being based on data from sensor information regarding an operational state of the transmission ( 102 ), and by which tooth-to-tooth positioning between toothing of the sliding collar ( 126 ) and the come-along toothing of the idler ( 130 , 132 ) is thereby released, so that the toothing of the sliding collar ( 126 ) and the come-along toothing of the idler ( 130 , 132 ) reference one another, the method comprising the steps of: providing the transmission ( providing the transmission ( controlling an activation motion of the actuator apparatus (
