Method and apparatus for controlling an automated gearshift

2007 
The invention relates to a method and a device for controlling an automatic multi-step shift transmission with one or two clutch-regulating valves (6, 8), via the clutch actuating cylinder for adjusting release couplings (K1, K2) are driven by means of a transmission control device. arranged in the fluid supply line (4) for the clutch control valves (6, 8) is a shutoff valve (12), by means of which at set neutral position of the gearbox, the fluid supply line (4) is blocked. Thus, a transition from the neutral position of the gearbox can, starting already preliminarily be inserted so that shorter switching times can be achieved and an inrush when shifting gears from the neutral position can be at least largely avoided in a starting gear or in reverse gear , Upon the occurrence of a system failure, it is ensured that in the neutral position of the transmission, a pressure buildup in the clutch actuating cylinders can not take place.
