Принадлежит:

Systems and methods for implementing a machine control system in a construction machine having an implement with an extender. The machine control system may include an acceleration sensor mounted to the implement and a processor configured to perform various operations. The operations may include determining that the extender is not moving and in response operating under a first control scheme. Operating under the first control scheme may include receiving acceleration data from the acceleration sensor, generating an estimated slope of the implement based on the acceleration data, and modifying a slope of the implement based on the first estimated slope by causing movement of at least one tow arm. The operations may also include determining that the extender is moving and in response operating under a second control scheme. Operating under the second control scheme may include maintaining the slope of the implement substantially constant. 1. A construction machine comprising:a tractor;a hopper coupled to the tractor;an implement coupled to the tractor via at least one tow arm, the implement having an extender;an acceleration sensor mounted to the implement; determining that the extender is not moving;', receiving acceleration data from the acceleration sensor;', 'generating a first estimated slope of the implement based on the acceleration data; and', 'modifying a slope of the implement based on the first estimated slope by causing movement of the at least one tow arm;, 'in response to determining that the extender is not moving, operating under a first control scheme, wherein operating under the first control scheme includes, 'determining that the extender is moving; and', 'maintaining the slope of the implement substantially constant.', 'in response to determining that the extender is moving, operating under a second control scheme, wherein operating under the second control scheme includes], 'one or more processors configured to perform operations comprising2. ...

A control apparatus for a soil compacting apparatus such as a vibratory plate has a movable operating element for specifying a running direction of the soil compacting apparatus by way of an operator, and having a hydraulic master device, with a master cylinder, in which a master piston can be moved to and fro in a linear manner, in order to generate a hydraulic signal. A hydraulic connector serves for coupling hydraulic components of the soil compacting apparatus and for transmitting the hydraulic signal from the master device. A transmission device is provided for converting the movement of the operating element into a linear movement of the master piston, it being possible for the operating element to be moved between a first position (V) and a second position (R). The first position corresponds to a maximum forward movement of the soil compacting apparatus, and the second position corresponds to a maximum reverse movement of the soil compacting apparatus. A latching device is provided for releasably holding the operating element in a predefined position, for example the first position. 1. A control apparatus for a soil compacting apparatus , comprising:an operator-controlled movable operating element for specifying a running direction of the soil compacting apparatus;a hydraulic master device having a master cylinder in which a master piston can be moved to and fro in a linear manner in order to generate a hydraulic signal;a hydraulic connector for coupling hydraulic components of the soil compacting apparatus to one another and for transmitting the hydraulic signal from the master device; anda transmission device for converting the movement of the operating element into a linear movement of the master piston, wherein the operating element is movable between a first position (V) and a second position (R), the first position corresponding to a maximum forward movement of the soil compacting apparatus, and the second position corresponding to a maximum reverse ...
