Abstract:
1. A method for controlling a shifting process from an initial gear into a target gear in a transmission with an active interlock shifting mechanism, the active interlock shifting mechanism including at least one shifting finger cooperating with a selector fork; and a disengaging geometry with a disengaging finger and a disengaging cam, the method comprising: determining whether a time critical shifting process or a non time critical shifting process occurs; and bringing the selector fork of the target gear into a safe shifting position through a shifting method compensating for errors not yet detected by the transmission in the shifting mechanism before the target gear is shifted when the non time critical shifting process is to be performed, wherein the non time critical shifting process is determined when at least one of the target gear is the neutral position or the initial or the target gear is a reverse gear, wherein when the target gear is in a neutral position, the shifting method includes using the disengaging cam to bring the selector fork into the neutral position, using the disengaging finger to bring the selector fork into the neutral position, and using the shifting finger to bring the selector fork into the neutral position.
