Abstract: A two (or more) piston pump system (10) is provided with both pumps (12) being crank (14) driven. The system does not have a mechanical camshaft, but a software algorithm, which acts like one in controller (20). The algorithm will LEARN and create a unique speed profile, which will mimic the mechanical camshaft. For practical purposes the speed profile of output gear is called Cam profile with software acting as an imaginary camshaft. The algorithm utilizes Crank Angle Estimation, Learn Curve Generation, Smoothing and Advance Timing Calculation.

Abstract translation: 两个（或多个）活塞泵系统（10）设置有驱动曲柄（14）的两个泵（12）。 该系统没有机械凸轮轴，而是一个软件算法，它像控制器（20）中一样。 该算法将学习并创建一个独特的速度曲线，这将模拟机械凸轮轴。 出于实际目的，输出齿轮的速度曲线称为凸轮轮廓，软件用作假想凸轮轴。 该算法利用曲柄角估计，学习曲线生成，平滑和提前计时。
