Adapting method for a valve steady-state characteristic operates for a valve triggered in a motor vehicle's gearbox hydraulic circuit

摘要

Reproducible pressure triggering in gearshift elements (46,47) ensures constantly good gearshift quality in automatic gearboxes. Pressure switches (44,45) monitor pressure to detect when a pressure threshold is reached. A valve ready-state characteristic gives a very accurate picture of actual proportions between a triggering signal and pressure being adjusted. An independent claim is also included for a device for triggering a motor vehicle's gearbox with a hydraulic circuit, a control device and valves triggered by the control device.
