Abstract
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 declaration ramp, rather instantaneously with changes in fuel pedal position.
