ABSTRACT:
The invention relates to apparatus for guiding a vehicle as it moves, of the kind comprising a detector (12) sensing deviation of the heading of the vehicle relative to a pre-determined direction and producing an electrical deviation signal, a hydraulic piston and cylinder device (16) steering the vehicle wheels (2) and control means (15) responsive to the deviation signal.
The technical problem is to provide apparatus of this kind whose operation is progressive and avoids systematic hunting.
In accordance with the invention, the detector produces a deviation signal which is proportional to the deviation of the vehicle heading from the pre-set direction, and the servo-valve provides progressive control as a function of the deviation signal.
