| 摘要 |
A dynamic pressure control system, such as a transmission pressure control system, is provided wherein one or more of electrical current command signals provided to a pressure control solenoid valve, such as a fast response variable force solenoid pressure control valve, are progressively trimmed in a manner to improve overall system pressure control performance by improving the overall commanded current response. The invention permits use of fast response pressure control solenoid valves and obtainment of in a manner to minimize overshoot and improve steady state accuracy, so as to thereby improve precision pressure control.
