ABSTRACT:
An automatic steering device is presented for controlling the direction of travel of an asphalt finisher during a paving operation. The device is provided with a laser generator (18) which projects a laser beam of a slit shape on a series of objects along the roadside which is selected to served as a reference line (A). An image recording device (17), a CCD camera, is disposed on the vehicle member (2), which records the projected laser light illuminating the objects and outputs a generated image (Ba) to a master controller (22). The master controller (22) determines the current deviation of the vehicle member (2) from the reference line (A) by the changes in the position of the generated image (Ba), and operates the automatic control device so as to steer the vehicle member (2) in the correct direction to permit the asphalt finisher to follow the reference line (A).
