Abstract:
1. A control system for a work machine having at least one hydraulic actuator, comprising: an input device adapted to generate a movement signal to control the movement of the at least one hydraulic actuator; a first sensor operatively engaged with the at least one hydraulic actuator and adapted to a sense a parameter indicative of a magnitude of a force exerted by the hydraulic actuator; a first controller disposed on the work machine and adapted to control the motion of the at least one hydraulic actuator, the first controller having a first receiver adapted to receive the movement signal and a first transmitter adapted to transmit a force signal including an indication of the force exerted by the hydraulic actuator; a second controller operatively connected to the input device, the second controller having a second transmitter adapted to transmit the movement signal and a second receiver adapted to receive the force signal; a second sensor adapted to sense a parameter indicative of a magnitude of a velocity of the hydraulic actuator and wherein the first transmitter transmits a velocity signal to the second receiver; and a force generator operatively engaged with the input device and adapted to exert a feedback force on the input device, the magnitude of the feedback force being related to the magnitude of the force exerted by the hydraulic actuator.
