Abstract
In a civil machine comprising a working tool provided on a vehicle with a travelling mechanism and a drive therefor, an automatic control system comprises a stroke detector for detecting the amount of stroke of a lifting cylinder operating to move the working tool up and down, an inclination angle detector for detecting the inclination angle of the vehicle, an arithmetic unit for obtaining data representative of the height of the working tool from the detection signals of the two detectors, and a control for operating the lifting cylinder by using the data to control the position of the working tool with high accuracy.
