    Title: Process for machine controlled fabrication of a support layer
    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a method for machine-controlled fabrication of a support layer in which a building site is processed with at least one clearing sheet, in which the actual conditions of the construction site to be processed are recorded and evaluated by means of nominal conditions and in which a correction motion is made. which is based on the data evaluation. Furthermore, the invention relates to a vehicle for machine-controlled production of a carrier layer, which vehicle comprises at least one lifting mechanism comprising a clearing blade, the drive of which is connected by means of control lines to a computer in the vehicle.
    Such methods are carried out with insulated appliances, the so-called leveling machines, for example, planing machines, bulldozers, graders (Kilver), erosion boards for rubber wheel loader or levellers that are dragged across the building site to be worked by tractors. In early procedures, it was up to the driver of the tractor to visually record the facts of the building site to be treated, to evaluate them by mental activity on the basis of scheduled nominal conditions, and to determine if and how a correction movement must be performed. For the driver of the tractor, this spectrum of tasks requires a high degree of skill and experience from the driver. In newer procedures, the driver is automatically relieved of generated process steps, so that the quality of a support layer produced by a method according to the invention is less dependent on values such as skills and experience. For such a relief of the driver, it is especially known to detect the actual conditions of the building site to be treated with sensors and to evaluate them on the basis of the nominal conditions determined. The sensory detection takes place, for example, by means of laser or GPS signals, which are processed in a computer in the vehicle. Such machining can range from just a graphical representation of the actual conditions in the cab of the tractor to automatically generated correction movements. However, it has been found problematic in the prior art that, when in contact with the building site, the clearing blade can only follow the corrective movements of the lifting mechanism with great inertia. Accordingly, they lead hydraulically generated
    GB 2018 70329 A1 correction movements of the lifting mechanism regularly for overriding, whereby the chassis of the clearing blade lifts the clearing blade from the ground whether the corrective movements are performed manually by a driver or automatically by means of a built-in computer. In particular, for a computer in the vehicle, it is not recognizable whether the lifting of the chassis can be traced back to a partial compression in the building site, a material accumulation in front of the clearing sheet or inertia in the building site.
    It is therefore an object of the invention to provide a method of the kind set forth in the preamble, thereby largely avoiding oversteer in the execution of the correction movements.
    This object is achieved by the features of claim 1. Advantageous embodiments of the invention are set forth in the subclaims.
    The method according to the invention is characterized in that a basic position is determined for the lifting mechanism of the clearing blade and that the correction movement starting from the basic position is possibly temporally and / or spatially limited. With such a restriction, a correction movement of the lifting mechanism is terminated even before an actual state has reached the specified nominal state. Thus, the correction motion acts as a kind of directional impulse or step. Only when the effect of such an impulse or step, taking into account the inertia of the gutter blade, is fully known from the preferably continuous detection of the actual states, a new correction motion is performed if necessary, whose temporal or spatial limitation may be of a different magnitude from the previous one. correction movement.
    Starting from the basic position means that the extent of each correction motion is thus measured from the basic position and that the restriction of each correction motion is independent of the level of a determined difference between an actual state and a nominal state. In contrast, only the direction of each correction motion is dependent on the difference, since it must counteract the difference. In this way, it is prevented by the optional temporal or spatial
    The limitation of the correction movement reliably means that with the method according to the invention, a lifting mechanism can be overridden.
    According to a first embodiment of the invention, the time-limited correction movement is initiated by manual contact activation and terminated again. In the case of manual contact activation, the restriction of the correction movement occurs prematurely, that is, even before reaching a defined threshold value, for example as a function of the activation duration, the activation pressure or the number of activation intervals.
    According to a further embodiment of the invention, the spatially constrained correction movement is automatically started by a computer controlled contact activation and automatically terminated again. In the case of the computer-controlled contact activation, the restriction of the correction motion is controlled by a computer program or a calculation algorithm.
    According to another embodiment of the invention, the spatially limited correction movement is initiated by manual contact activation and terminated automatically by computer controlled contact activation. In this semi-automatic controlled contact activation, the limitation of the correction movement takes place after reaching a certain threshold value.
    In order to reliably prevent any override in both a manual and an automatic contact actuation, the lifting mechanism is automatically retracted to its basic position after the completion of a correction motion. The retraction can be started either immediately at the end of the contact activation or with a time delay. Thus, repeated contact activation does not result in a correction movement of increased magnitude, but only leads to a repetition of the correction movement. Based on the data evaluation, it is also possible, as a starting point, that the lifting mechanism is not returned to the basic position after the completion of a correction movement, but that an additional correction movement is performed if its restriction is different from that of the previous correction movement.

    In order to produce a support layer that is largely independent of the driver's skills and abilities, it is proposed to detect the actual conditions of the building site to be treated using sensors and to evaluate them in a computer-controlled manner on the basis of the prescribed nominal values. conditions. Thus, it is within the scope of the invention that the actual conditions of the building site to be treated are visually defective and manually evaluated, especially by intellectual activity on the basis of the nominal conditions prescribed. The sensory detection is preferably carried out via at least two inductive sensors arranged as a side-by-side transducer.
    If the support layer to be produced is provided to produce a surface for traffic bounded by a curb, it is proposed to set the nominal modes by a reference value gauge running at the curb. In the following, the actual states of the building site to be processed are assessed on the basis of the data provided by the reference value meter and, on the basis of this data evaluation, a correction motion is performed if necessary.
    According to a further embodiment of the invention, the correctional movement consists of at least two individual movements produced in the lifting mechanism.
    The individual movements are preferably done by swinging movements generated by lifting cylinders, over which the clearing blade is height-adjustably suspended in the chassis of an insulated apparatus. In order to form a transverse direction of the movement gradient, the cylinders can also be controlled individually.
    With regard to the vehicle, the invention is characterized in that the lifting mechanism has a preset basic position and that with the computer in the vehicle around the basic position a temporal and / or spatial restriction is created for the lifting room's own space of movement. Thus, the basic position is a defined starting position in which the lifting mechanism can be moved back at any time and which is the reference point for each temporal and / or spatial constraint. The vehicle according to the invention is either designed as an insulated device or as one
    DK 2018 70329 A1 towing device in which the insulated device is connected to a towing vehicle. Thus, the computer in the vehicle is either an integral part of the tractor, otherwise it is an integral part of the insulated apparatus with a control unit which can be arranged in the cab of the tractor, enabling a practical remote control of the computer in the vehicle from the cab. While with the time limit some kind of electronic time relay is formed, the spatial boundary acts as a kind of electronic position switch or limit switch. In any case, the restriction represents a forced reduction of the mechanically possible range of motion in a preset basic position, thus largely avoiding overstepping of the lifting mechanism.
    According to a first embodiment of the vehicle according to the invention, this has at least two clearing blades between which the wheels are placed on the chassis. Especially for machining a brain area of a building site by means of maneuvering, the lifting mechanism is controlled with the correction movement of the clearing blade located in the direction of travel in front of the wheels. The clearing blade behind the wheels in the direction of travel is driven from the basic position to a raised rest position.
    An embodiment of the invention, from which further inventive features are shown, is shown in the drawing. It shows:
    FIG. 1: a perspective view of an application example with an isolated apparatus for carrying out the method according to the invention; and
    FIG. Figure 2 is a perspective view of the application example of Figure 1, but viewed from a 90 ° perspective.
    FIG. 1 and 2 show an insulated apparatus 1, on which a single-axle chassis 2 is mounted a height-adjustable clearing blade 3 via a lifting mechanism 4. The chassis 2 has a drawbar 5, through which the insulated apparatus 1 is coupled to a tractor
    6. For machine controlled fabrication of a support layer 7, the insulated apparatus 1 with the tractor 6 is pulled over a building site 8 to be machined. In addition, the insulated apparatus 1 has two side-by-side data transfer devices 9, 10
    DK 2018 70329 A1 page on its clearing sheet 3 in the direction of travel, through which the actual conditions of the building site 8 to be treated are defective. To evaluate the actual states on the basis of predetermined nominal states, a navigation device 11 is located on the building site 8 to be machined. Based on the data light, a correction motion is performed on the clearing blade 3, which is either temporarily and / or spatially constrained from a basic position defined for the clearing blade 3.
    All features mentioned in the foregoing description and claims may be combined in any selection with features of the independent claim. The description of the invention is therefore not limited to the described or combinations of features according to the claims, but all meaningful combinations within the scope of the invention must be considered as described.
