Abstract

A driving control device and a control method therefor suitable for industrial vehicles, particularly for construction vehicles such as a hydraulic power shovel, which makes it possible for a driver to drive a vehicle in a desired direction easily without any illusion. To accomplish this object, the method of the invention comprises tilting a driving lever in a desired driving direction, detecting the angle of the operation direction by a lever angle detector, detecting a relative angle of rotation between an upper swivelling member and a lower driving device by a car body swing encoder, sending these signals to a controller, judging the swinging direction of the lower driving device through the calculation by the controller, sending then the output signal to a driving operation valve to swing the lower driving device without travelling, stopping it when the lower driving device becomes parallel to the operation direction of the driving lever, and moving straight the lower driving device in the operation direction of the driving lever. The angle of the operation direction of the driving lever and its tilt angle may also be detected by the lever angle detector and then the lower driving device may be swung without travelling at a speed proportional to the tilt angle of the operation lever or may be moved straight. Furthermore, the lower driving device may be swung without travelling and driven by detecting the angle between an upper swing body and the direction of north of terrestrial magnetism by a gyrocompass.
