VIRTUAL BRAKING SYSTEM FOR HYDROSTATICALLY DRIVEN VEHICLE

摘要

A hydrostatic vehicle drive system features a "virtual" braking system designed to emulate the braking response of a mechanically driven vehicle equipped with an automatic transmission and disk or drum brakes. A microprocessor controls output of the pumps used to power the hydraulic motors, and causes the power output to decrease independently and gradually according to a decelaration ramp, rather than instantaneously with changes i n fuel pedal position.
