Abstract: In an automatic transmission for a motor vehicle which is controlled by an electronic transmission control device which continuously exchanges signals with a digital engine electronic system of an internal combustion engine, to reduce the thermal load on the automatic transmission in emergency operating mode, a transmission-independent program module (M1) of the digital engine electronics system presets an admissible maximum engine torque for the emergency operating mode (M_mot_max_not).

Abstract: Within the scope of the process for variator slip treatment in continuously variable automatic transmissions of a motor vehicle, upon detection of variator slip, a characteristic field (1) of slip meter is locally incremented according to ratio value (iv) and to engine torque (M_mot) and simultaneously an evaluated slip meter (2) of an evaluation module (3), likewise according to ratio value (iv) and to engine torque (M_mot), is increased, wherein via the evaluation module (3), the variator slip is assessed according to duration and intensity. Besides, a characteristic field (4) of slip status meter connected with the evaluated slip meter (2) is incremented together with the evaluated slip meter (2), a signal being passed on to an error memory (5) so that, with the entry of the error, slip, evaluated slip and slip status meter are entered in the error memory (5) as environmental conditions.

Abstract: The method for increasing the driving comfort of motor vehicles, specially during load reversal operations, by control of the dynamics of the driver's desired torque consists in that to a first microprocessor (1) signals are fed relative to the accelerator pedal position and rotational speed of the internal combustion engine, after which the output signal originating from the first microprocessor (1), together with a manually adjustable torque request signal, are fed to a second microprocessor (2), the output signal of which passes through a filter (5) as driver's desired torque, wherein the filtering time produces a damping of load reversal and jolt between driver's wish and internal engine speed ratio.

Abstract: In a process for controlling the torque of an internal combustion engine, an automatic gear system driven by the internal combustion engine includes a gear control device (1) and the internal combustion engine has a control device which, based on speed, load and, where appropriate, temperature signals, controls an ignition angle of an ignition system and/or an injection pulse width of a fuel injection system. The gear control device (1), for its part, controls on the basis of speed and load requirement signals the gear changes of the automatic gear.
