Patent DE-4217270-A1 (DE)
Inventor: BECKER GERNOT DIPL ING
IPC: F16H61/06
Filed: 1992-05-25
Abstract: The invention relates to a process for the adaptive correction of the gear-changing quality of an automatic gearbox which is connected to an engine and in which friction components in the form of clutches or brake bands can be engaged via pressurised or hydraulically actuated adjusters to effect gear changes, the pressure in the line exerted by the adjusters is detected by means of an electronic device and corrected depending on various operating parameters. Here, for each specific gear change, besides the resulting transmission ratio (R) as a function of the time from the triggering to the end of the gear changing process, the first derivation (dR/dt) is also found and in the electronic device (1) an allocation of values of the transmission ratio (R) to the corresponding values of the first derivation (dR/dt) is produced in the form of a characteristic, whereby this measured characteristic is compared with reference characteristics in the device (1) including a range of tolerance, and in the event of inequality, a correction factor (KF) is found which leads at the next identical gear change to an incremental increase or decremental decrease in a correction value (Kx) by the correction factor (KF), thus producing a correction in the line pressure or the oil flow rate by means of the adjusters (8, 9) effecting the pressure or oil flow, controlled by the electronic device (1), in accordance with the correction value (Kx).
