摘要： A process is provided for operating a vehicle transmission with preferably electrohydraulically actuatable friction elements for shifting between different transmission steps, in a vehicle with at least one drive engine in which an actual value of at least one of the quantities characterizing the shift process is determined for each shift process, which actual value is compared with a theoretical value that can be established and stored. When the actual value deviates from the theoretical value, a regulated quantity for at least direct influencing is changed by a correction value that can be established. For each shift process, the time duration for the output of a gear shift signal up to the beginning of the synchronization process and/or the change of the drive rpm during this time period is determined as a first and/or second actual value of the quantity characterizing the process. When the time period up to the beginning of the synchronization process deviates from the pre-given theoretical time period or if the drive rpm change given in advance is not achieved after a shift process, the initial pressure value is changed by the correction value in order to introduce the necessary pressure force of the coupling components that can be coupled together in a force-interlocking manner.

摘要： The invention relates to a process for the control of the shifting process of a vehicle with electro-hydraulically actuatable friction elements for the shifting-over between different transmission stages in a vehicle with at least in addition a drive engine in which a current actual value is determined for at least one magnitude characterizing the shift process in each shifting process; the actual value is compared with an establishable and/or storable desired value; on deviation of the actual value from the desired value, the control pressure for the at least indirect influencing of the magnitude characterizing the switching process is adaptively changed by a determinable, calculatable or prescribable first correction value for the achieving of an optimal shifting behavior and the course of the altered magnitude is storable in each case as new characteristic curve of the desired values. The invention is characterized by the following features: in at least the shifting processes in which through a further adaption no satisfactory shifting courses can any longer be insured, at least one actual value--the drive turning rate--is determined for a magnitude characterizing the acceleration of the turning rate to be synchronized in force-flow direction in the drive line on the input side of the coupling at a time point after the beginning of the synchronizing process; the actual value either of the acceleration of the turning rate to be synchronized or of a magnitude at least indirectly characterizing the acceleration of the turning rate to be synchronized, or that of the turning rate to be synchronized, is compared with a desired value; on deviation of the actual value from the desired value the control pressure is altered by a second correction value until the desired value course of the turning rate to be synchronized is set in, and, moreover, the course of the control pressure characteristic curve is replicated at higher pressures.

摘要： The invention concerns a method for operation of a drive unit of a vehicle, including a drive machine and a transmission with at least two gears. A quantity that characterizes acceleration of the vehicle and a quantity that characterizes the power of the drive engine are continuously determined. A gear shift speed range and a second speed range bounded by a lowest and highest attainable speed in the target gear can be established for a gear shift process in the initial gear. The gear shift speed range is bounded at least by a lower gear shift speed and an upper gear shift speed and the second speed range is bounded by a lower target speed, as well as an additional speed. The gear shift process is initiated as a function of the determined acceleration. The lower target speed is achieved in a gear shift process in a first limiting stage (high acceleration at low input speeds or limited deceleration at low input speeds) during initiation of a gear shift at a number of gear shift speeds. The gear shift process between the first limiting state and the highest attainable speed in the target gear is initiated as a function of the determined quantities in the gear shift speed range in the initial gear.

摘要： A method for the control of shifting processes in a vehicle transmission from an initial gear to the next higher target gear includes the steps of continuously determining the vehicle acceleration (a) and the driven rpm (n.sub.2) behind the vehicle transmission. A shifting process is triggered when the acceleration value (a) and the essentially simultaneously recorded driven rpm value (n.sub.2) fall on a shifting point which lies on a shifting characteristic (n.sub.2 (a)) in an acceleration-driven rpm diagram, where the shifting characteristic (n.sub.2 (a)) has a stepped course with at least two break points (a.sub.-- max; a.sub.-- min) and the slope of the shifting characteristic for acceleration values a.sub.-- min
