The invention relates to a process for carrying out an automated clutch actuation of a motor vehicle with a drive engine and a transmission, connected to said drive engine by way of a clutch, in which process the clutch exhibits both an opened and a closed operating position, whereby to introduce unpowered operating phases the clutch is transferred by means of automation into the opened operating position and to introduce powered operating phases it is transferred by means of automation into the closed operating position. To design such a process more reliably and comfortably, the variables, from which a dangerous situation in time or its termination can be concluded with a certain probability, are measured, according to the invention, so that the clutch can be moved into an operating position (opened or closed), which makes it possible to carry out faster the subsequent request of the driver&#x2014;such as an acceleration request or a braking request.

Method for carrying out an automated clutch actuation during non-driven operational phases

In a device for controlling the speed of an internal combustion engine driving a utility unit with a speed control circuit for the internal combustion engine and with a load control circuit for the utility unit, the device includes sensors and an evaluation unit for detecting and evaluating the state of the system as a whole, and an arrangement for an intervention in the speed control circuit and/or the load control circuit depending on critical relevant system states in order to achieve a reduction in the system complexity and thus a better control of the dynamics of the system as a whole.

In a process for automatic adjustment of handling of a motor vehicle having an internal-combustion engine, operating and condition quantities are determined and compared with reference values. If the operating and condition quantities deviate from the reference values, adjusting signals are generated for adjusting vehicle and engine components. In order to recognize predetermined driving situations, and to make corresponding adjustments for influencing the vehicle handling, starting and ending of predetermined driving modes (acceleration operation, deceleration operation and constant drive operation) are detected by logically evaluating diverse operating and condition quantities. The conditions for detecting the start of a driving condition differ from the conditions for the end of the same driving condition. When one of the conditions for the start or the end of an acceleration operation, of a deceleration operation or of a constant driving operation exists, adjusting signals are generated for automatically adjusting of vehicle and engine components.

Process and system for the automated influencing of the vehicle handling of a motor vehicle having an internal combustion engine

A method for controlling a heating and/or air-conditioning apparatus is provided, wherein, through an intervention unit, a user can perform interventions which lead to different settings of the heating and/or air-conditioning apparatus. Various parameters are read into a control unit and are processed. According to the method, climatic situations are defined by the parameters; upon a user intervention a particular climate situation is detected; the climatic situation is associated with the particular user intervention; and in a prevailing climatic situation the settings of the climate control system pertaining to the associated user intervention are carried out.
