  • Solenoid transmission hydraulic model method
    Patent number: 9518679
    Abstract: A method is disclosed for determining off-temperature accuracy information of a solenoid fluid control valve. The method comprises performing a current sweep at a first temperature, and for at least one command pressure, determining an error in a control pressure based on the current sweep. The error may be determined at the first temperature. A metric may then calculated based on the current sweep, and a pressure error offset may be determined for a second temperature based on the metric. The pressure error offset may describe a difference between the error in control pressure at the first temperature and an expected error in control pressure at the second temperature.
