METHOD OF AND DEVICE TO CONTROL TRANSMISSION OF VEHICLE Russian patent published in 2004 - IPC

FIELD: transport engineering. SUBSTANCE: proposed method of control of transmission of vehicle containing planetary gearing 2 shifted in and interlocked by signals from control link, clutch 10 and step gearbox 20 comes to conversion of speed signal of one of shafts of planetary gearing 2 into two stable states of control link, respectively, shift-in and interlock of gearing 2 and removing clutch release signal. First signal is formed when clutch 10 is released and is supplied to control link to change it into other stable state. Second signal is formed to preclude change of control link into initial stable state for time of action of first signal. First signal acts within preset time also after engagement of clutch. Proposed method provides forming of third signal preventing change over of control link into interlock state of gearing 2 when starting from half. EFFECT: improved traction and dynamic and performance characteristics of vehicle, improved reliability. 5 cl, 12 dwg
