摘要： A method (42) for preventing incorrect gear shifts in automatic transmissions (14) of motor vehicles comprising the following steps: determining a current output torque (Mis) of a source gear (GSOURCE); generating a history of output torques by storing the current output torque in the source gear (GSOURCE) for a time interval having a predetermined duration; determining an absolute value of a minimal output torque (Mmin) and an absolute value of a maximum output torque (Mmax) from the history (60) of output torques, comparing the two values and determining the greater absolute value; determining (S3) an absolute value of a target torque (MTARGET) of a target gear (GTARGET), if an instruction for a gear change exists; comparing (S4) the absolute value of the target torque (MTARGET) with the greater absolute value; and shifting (S5) the transmission (14) from the source gear (GSOURCE) to the target gear (GTARGET), if the absolute value of the target torque (MTARGET) is less than or equal to the greater absolute value (FIG. 2).

摘要： Method for shifting, in particular engaging and/or disengaging, gears in an automatic multi-stage gearbox of a motor vehicle, wherein the gearbox comprises a drive input shaft (18) connectable to an engine drive output shaft (16) by means of a friction clutch (12) which acts as a separating clutch (12), and a drive output shaft (20) couplable to a drive wheel or to drive wheels of the motor vehicle, wherein a shift process takes place, in particular only, as a function of rotational speeds (n) of the shafts, wherein each gear is assigned a synchronizing device (36), which acts as a shift clutch, in order to connect the drive input shaft (18) to the drive output shaft (20), comprising the following steps: setting the separating clutch (12) into a dragging position such that a low, preferably predefined, drag torque is transmitted from the engine drive output shaft (16) to the drive input shaft (18), which drag torque is sufficient to bring a rotational speed (nIS) of the drive input shaft (18) when the shift clutch (36) is open to a rotational speed (nM) of the engine drive output shaft (16); adjusting the rotational speed of the engine drive output shaft (16) to a predetermined value (I) which differs sufficiently from a rotational speed of a source gear or from rotational speed of a target gear; setting the shift clutch (36) of the source gear towards an open position in order to separate the drive input shaft (18) and drive output shaft (20) from one another; detecting the rotational speed (nIS) of the drive input shaft for a predetermined time period which follows at least a time (t1) when the shift clutch (36) of the source gear is in the open position; determining a change in the rotational speed (nIS) of the drive input shaft (18) during the predetermined time period; and determining whether the change which is determined in this way lies within predefined tolerances of an expected rotational speed change (FIG. 8).

摘要： An actuator arrangement for a clutch of a drive train for motor vehicles. The clutch is prestressed into an opened position and can be activated electromechanically. An electric motor can be coupled to the clutch in order to activate it. A control unit actuates the electric motor. The actuator arrangement has a safety device which is connected to the electric motor parallel to the control unit. The safety device is configured, in the case of a fault state, to supply electrical power to the electric motor independently of the control unit in order to open the clutch.

摘要： A method for controlling an automated step-by-step variable transmission which has a plurality of gear stages which set up a different transmission ratio in each case. The method comprises the steps: a) detecting whether a gear stage is to be engaged, b) detecting an input actual variable which is substantially proportional to an input rotational speed of the step-by-step variable transmission, and an output actual variable which is substantially proportional to an output rotational speed of the transmission, c) checking as to whether a difference between a ratio of the input and the output actual variables and the transmission ratio which would be set up by the gear stage is smaller for a predefined timespan than a predefined tolerance range, and d) determining a fault state if the difference does not lie within the tolerance range for the predefined timespan.
