    • A system for calibrating an input electrical signal to an individual pressure control device includes the steps of providing a target pressure-to-current (P/I) threshold, providing a lower estimated P/I threshold, and providing an estimated P/I curve that passes between the target P/I threshold and the lower estimated P/I threshold. Next, the method determines a lower actual P/I threshold at a pressure equal to the pressure at the lower estimated P/I threshold. A maximum offset current is calculated from the difference between the currents at the lower actual P/I threshold and the lower estimated P/I threshold. Finally, the system calculates a calibrated P/I curve. The calibrated P/I curve includes the target P/I threshold and the lower actual P/I threshold. The slope of the calibrated P/I curve is calculated as a proportional value of the maximum offset current.
    • 用于将输入电信号校准到各个压力控制装置的系统包括以下步骤:提供目标压力 - 电流(P / I)阈值,提供较低的估计的P / I阈值,以及提供估计的P / I曲线 其在目标P / I阈值和较低的估计P / I阈值之间通过。 接下来,该方法在等于较低估计P / I阈值处的压力的压力下确定较低的实际P / I阈值。 最大偏移电流根据较低的实际P / I阈值和较低的估计P / I阈值之间的电流差来计算。 最后,系统计算校准的P / I曲线。 校准的P / I曲线包括目标P / I阈值和较低的实际P / I阈值。 校准的P / I曲线的斜率被计算为最大偏移电流的比例值。

    • Determining performance of an internal combustion engine coupled to a pump of a torque converter may include determining a rotational speed of the pump, determining a rotational speed of a turbine fluidly coupled to the pump, determining an engine output torque value, corresponding to torque applied by the engine to the pump of the torque converter, as a function of the rotational speed of the pump and the rotational speed of the turbine, and storing the engine output torque value in a memory unit. Alternatively or additionally, engine horsepower may be determined as a function of the engine torque and/or a fuel efficiency of the engine may be determined as a function of the horsepower and fueling rate of the engine. The engine output torque value, horsepower value and/or fuel efficiency may be stored in a memory unit and/or displayed on a display unit.
