TH94418B - Electronic camshaft motor control for piston pumps - Google Patents

Abstract

Two sets of piston pump systems (Or rather) were provided in such a way that the two pumps (12) were driven. The system does not have a mechanical camshaft, but has a software algorithm that does Such camshaft-like functions in a regulator (20), such an algorithm learns and generates The curves show a specific velocity that is mimicked from a mechanical camshaft. For practical purposes, the curves showing the velocity of the transmission gear are also called cam curves. Software that acts as a hypothetical camshaft. The algorithm uses crank angle estimation, learning curve generation, curve smoothing, and timing advance calculations.
