Problems solved by technology

If the gear selector is in the inertial flight phase, however, it still tries to engage in the shifting gear, which may cause "scratching" between the parts due to possibly very high rotational speed differences and thus Possible damage to parts wear (Bauteilverschleiß) and driving comfort (Fahrkomfort) due to disturbing noise

Abstract

The invention relates to an operating method for an automatic transmission of a motor vehicle, in particular for an automatic shift transmission and / or a dual clutch transmission. Automatic transmissions can be operated cost-effectively, in particular with reduced component wear and / or with increased service life, and / or the driving comfort of the vehicle can be improved by virtue of the operating method When at least one driven wheel (aR) is detected by the lift of the lane during braking, then for the duration of the braking, there is a shifting process in an outstanding gear (G3) to the gearbox The engagement of the middle gear ( G3 ) is prevented and / or the start of the shifting process into the gear ( G3 ) of the transmission is prevented.

Description

Technical field [0001] The present invention relates to a running method of an automatic transmission (Automatischesgetriebe), especially automatic shift gearbox (Automatisches Schaltgetriebe), and / or DoppelkupplungsGetriebe, according to the present invention. Background technique [0002] Motor vehicle gearbox, such as automatic shift gearbox, and / or dual clutch gearboxes have at least one or more corresponding gear or a plurality of corresponding determinable gears for at least one determined gear or a plurality of respective determinants of the corresponding gearbox. Bit gear regulator (Gangsteller). Such a gear regulator can be designed, for example, in the form of a movable / shifted bonding sleeve (SchieBemuffe) and / or implemented. Here, the gear to be switched or the gear to be designed to be designed to be swapped in the gear is rotationally coupled to the axis of the gearbox and disengaged or decoupled from the shaft of the gearbox. Thus, a gear or gear stage has ...
