Apparatus for controlling a drive system for an industrial truck |
摘要 |
An apparatus for controlling a drive system for an industrial truck having an internal combustion engine and a hydrostatic transmission wherein the hydrostatic transmission has a pump the delivery volume of which is variable and at least one hydraulic engine acting on at least one wheel of the industrial truck, comprising a first controller for the speed of the industrial truck in which a desired speed value compares to a actual value arriving from a speed transducer, further in which a speed controller determines a corresponding desired motive force and in which the signal for the motive force and the actual speed is provided to a characteristics stage in which at least one characteristic is stored which assigns approximately optimal rpm values to power values of the internal combustion engine and presets a corresponding desired-value signal for the number of revolutions of the internal combustion engine, and a second controller underlying the first controller having a desired-value and actual-value comparator in which an actual value of the pump arriving from a pressure transducer is compared to desired-pressure value, further in which a pressure controller produces a variation signal for the delivery volume in the pump, wherein a desired-value transducer for the pressure determines the desired value from the desired motive force and parameters of the drive system.
