System for calibration of electrohydraulic pump start current based on engine's output torque signal

Abstract

A system for calibrating an electrohydraulic pump for a vehicle having a propel system that includes an engine connected to the electrohydraulic pump. A micro-controller having software and an input device is connected to a plurality of sensors mounted about the vehicle. The software uses a plurality of parameters to convert internal analog drive signals into analog output signals to control the electrohydraulic pump and motion of the machine where the parameters include a forward start current value and a reverse start current value.
