Abstract: A data storage system for a motor vehicle has at least two control units (1) for controlling one or several vehicle components each, at least two memories (2) for storing data that characterize the route to be traveled on in future, and an interface (3) to a data source (4). Every control unit (1) inquires with the data source (4) a subset of the route data contained therein via the interface (3) and stores the route data transmitted in response in the memory (2) associated with the respective control unit (1).

Abstract: A method for controlling an automatic transmission in a drive train of a motor vehicle having a transmission controller selecting and shifting gears of the transmission includes determining a new gear by reference to gear shift characteristic curves and generating a gear shift instruction as soon as a working point of the drive train exceeds a gear shift characteristic curve. The transmission controller determines a new gear that is expected to be engaged shortly. If the new gear differs from the current gear, an initial phase of the gear shift is carried out and the gear shift is completed as soon as the gear shift instruction has been generated. The initial phase is carried out as soon as the working point drops below a predefined distance from the gear shift characteristic curve.
