26	Method for controlling a motor vehicle's automatic gearbox reduces an engine's torque with an automatic gearbox driven by an internal combustion engine affected by an accelerator pedal	DE19951107	1999-10-23	DE19951107A1	2001-05-23	HENNEKEN MARKUS; HERBSTER KAI-UWE; JAUCH FRIEDEMANN; MAUZ THOMAS; SCHULER FRANZ-JOSEF
A signal (HDK) in proportion to an accelerator pedal's position passes to an electronic gearbox control (EGS) storing gearshift programs (SKL,SKLred) with gearshift mapping. Reduction in engine torque is accounted for in a gearshift program selection routine, so that in a quasi-stationary condition and during an approximately full load operation an engine torque reduction factor (kMOMred) acts as an effective variable for selecting the gearshift program.

By a controller which controls a speed-change control valve for switching a hydraulic pressure to be supplied to each of cylinder chambers of each of pulleys of a continuously variable vehicular transmission, the speed reduction ratio is controlled such that the engine revolution speed becomes a target revolution speed which is set depending on the running conditions of a vehicle. When an accumulated time of high-speed operation at which Ne becomes higher than a predetermined first set revolution speed exceeds a first set time, an upper limit value of Ne or the target revolution speed is corrected to decrease. Further, when the duration time of a low-speed revolution below a predetermined second set revolution speed which is smaller than the first set revolution speed exceeds a second set time, the upper limit value of Ne is corrected to increase or the correction to decrease the target revolution speed is stopped.

The drive-train control (1) is used in a road vehicle. It may be connected to the engine (4) and an automatic transmission (8). It employs an engine control (2) for adjusting the engine torque output and an electronic transmission control (6) controlling the gear changing, which are coupled together via a data interface (16). The electronic control systems separately regulate the engine and the automatic transmission. An interface is used for transmission of a condition signal (AS) indicating the operating condition of the engine to the transmission control, so that a rapid variation in the engine speed is matched by a corresponding gear change.

40	Method and device for actuating an automatic gear system	DE4329978	1993-09-04	DE4329978A1	1995-03-09	ZHANG HONG DR
The present invention is based here on a system for actuating an automatic gear system (13) of a motor vehicle which is equipped with a drive unit (11) which is subject to consumption of operating media. The gear tranmission ratios are set here in such a way that the drive unit is operated at its operating range which is optimum for consumption. The setting of the gear transmission ratio takes place here as a function of at least one first signal (n ab) which represents the gear output r.p.m. and/or the engine r.p.m. and/or the gear input r.p.m. Furthermore the setting of the gear transmission ratio is dependent on a second signal (mo ab) which represents a desired value for the torque output by the gear system. The setting of the gear transmission ratio takes place here by means of a comparison of the first signal and/or the second signal by means of at least one threshold value (mo ab stst). According to the invention there is provision for the at least one threshold value to be at least dependent on parameters which influence the maximum torque to be output to the gear system by the drive unit.
