Abstract:
A control system for controlling the ground speed of a work machine wherein the work machine includes a brake control system for controlling such ground speed, said control system comprising:a first sensor for determining the angle of inclination of the terrain upon which the work machine is operating;a second sensor for determining the ground speed of the work machine; andan electronic controller coupled with said first and second sensors for receiving signals therefrom, said controller being operable to receive a signal from said first sensor indicative of the angle of inclination of the work machine, and a signal from said second sensor indicative of the ground speed of the work machine;said controller being further coupled to the brake control system of the work machine for controlling the operation thereof, said controller being capable of outputting signals to the brake control system to retard the ground speed of the work machine; andmemory means coupled to said controller and having stored therein maximum ground speed limits for the work machine based upon the angle of inclination of the terrain upon which such machine is operating;said controller outputting a signal to the brake control system of the work machine to retard the ground speed of the work machine when said controller receives a signal from said first sensor indicative of the particular angle of inclination of the terrain upon which the work machine is operating, when said controller determines the maximum ground speed of the work machine based upon the signal received from said first sensor, and when said controller receives a signal from said second sensor indicative of the ground speed of the work machine being equal to a predetermined ground speed.
