Pressure and flow control system for automatic transmission of hybrid powertrain of vehicle, has control valve which receives pilot signal from pilot valve and outputs control signal to control hydraulically-controlled component

摘要

The control system (500) has hydraulically-controlled component (510) arranged in an automatic transmission, and a pilot valve (512) which produces pilot signal. The pilot valve comprises micro-electromechanical system (MEMS) micro valve element (516). A control valve (514) in fluid connection with the pilot valve, receives the pilot signal and outputs control signal for controlling the hydraulically-controlled component.
