The controller can also update the slope value to be retained and keep the tilt angle at the operator's last grade input. Alternatively, the controller may terminate processing of the operator's incline inputs and maintain the incline angle of the incline adjustment to be maintained. The input of the tilt to be maintained may include an activation control and a tilt selector. The angle of inclination and the slope value to be maintained can be set to the angle selected by the tilt selector. The tilt selector may include operator-settable and fixed tilt values. Operator-settable executive tilt commands and fixed non-executive tilt commands.

    AUTOMATIC ADJUSTING ANGLE ADJUSTMENT OF AN ELECTRO-HYDRAULICALLY-CONTROLLED RIPPER PACK
    FIELD OF THE INVENTION
    This subject invention relates generally to an automatic control system for a ripper used for construction machinery, and more particularly to automatic control of the incline of the ripper.
    BACKGROUND OF THE INVENTION
    Typically, a ripper mounted on construction machinery such as a tractor is dog-footed by the operator, who raises or lowers the ripper or varies the incline of the ripper based on experience, nature of the ground, vehicle speed and other working conditions. In a ripple carrier system with adjustable pitch, changing the height of the ribbed carrier can alter the incline of the ripper. This will change the ripping characteristics of the system while the ripper is still engaging in the backing material. It would be desirable to retain the incline of the ripper even as the working depth of the ripper changes.
    DESCRIPTION
    A system is disclosed which maintains the angle of inclination of a ripper within a range of the height of the ripper: this can be accomplished by measuring the length of the ripper's pitch and stroke cylinders and by automatically actuating the pitch cylinders to maintain the pitch angle as the length increases of the lift cylinder changes.
    There is disclosed an automatic system for maintaining the inclination of the ripper comprising a lift cylinder and a tilt cylinder of the ripper. The tilt retention feature of the Ripper includes operator inputs for lift and tilt, a tilt control operator, tilt and lift cylinder sensors, and an electro-hydraulic controller for the ripper. The incline input of the operator generates an incline signal of the operator for controlling the incline angle of the ripper, and the hoist input of the operator generates a lift signal of the operator for controlling the raising and lowering of the ripper. The tilt holding operator's control unit generates a signal to activate the holding of the tilt. The tilt cylinder sensor is connected to the tilt cylinder of the ripper and scans the position of the ripper's tilt cylinder and produces a LATCH, .....,
    Tilt cylinder position signal. The lift cylinder sensor is connected to the lift cylinder of the ripper and senses the position of the lift cylinder of the ripper and generates a lift cylinder position signal. The ripper's electrohydraulic controller processes the operator's lift and tilt signal, the lift and tilt cylinder position signal, and the pitch hold activation signal, and outputs and outputs the ripper tilt and lift cylinder commands indicative of the ripper's tilt angle Maintain adjustment of the Ripper's tendency to maintain. Once the tilt hold activation signal is generated, the ripper's electrohydraulic controller can process the operator lift and pitch signals that update the ripper's toe to maintain the incline signal set by the last operator set incline and the ripper's pitch angle maintained at the latest setting for the incline of the ripper. Alternatively, once the tilt maintaining activation signal is generated, the ripper maintaining the inclination of the ripper can be stopped, and the ripper's electrohydraulic controller can stop processing the operator's inclination signals and adjust the incline angle of the ripper Maintain Rippers at the set slope value.
    The slope maintenance controller may include an activation controller to generate the slope maintenance activation signal and a tilt selector to select a desired ripper angle of inclination. Once the activation control generates the tilt maintaining activation signal, the angle of inclination of the ripper and the ripper slope retention setting can be adjusted to the desired tilt angle selected on the tilt selector, and the ripper's electrohydraulic control can control processing terminate the tilt signals of the operator. The tilt selector of the ripper may include a number of pre-determined ripper angle adjustments and a selection control of selecting the desired ripper angle of inclination from the number of predefined ripper angles. The selector for determining the incline of the ripper may be a menu, a slider , a Multiposionierungshalter or other appropriate input device.
    The tilt selector can be adjusted by the operator and has a fixed tilt setting. If the activation controller generates the tilt hold enable signal and the tilt selector selects the operator adjustable tune-in setting, the Wen of the hot-keys can select
    Inclination can be adjusted to the current inclination angle of the ripper, and the attitude to be maintained inclination can be updated with each inclination signal of the operator to the tilt angle of the ripper set by the slope signal of the operator. Once the activation control generates the tilt-to-maintain activation signal and the tilt selector dials the fixed tilt setting, the ripper's incline angle and tilt-to-hold setting can be set to the fixed tilt value, and the ripper's electro-hydraulic control can stop processing the operator's tilt signals ,
    The tilt cylinder commands of the ripper may be output to a tilt slider valve of the ripper that controls the angle of inclination of the ripper; and the ripper's lift cylinder signal commands may be output to a ripper valve of the ripper that controls the lifting and lowering of the ripper. The electrohydraulic controller of the ripper may also include a position processor that determines a position of the ripper based on the position signal of the pitch cylinder and the lift cylinder and provides the ripper position for further processing by the electro-hydraulic controller of the ripper.
    There is disclosed a method for maintaining the incline of the ripper for the control of a tilt cylinder-connected ripper that controls the angle of incline of the ripper and a lift cylinder that raises and lowers the ripper. The method for holding the incline of the ripper involves activating an automatic function for holding the incline of the ripper; the setting of a value for the slope to be maintained; reading a position of the tilt cylinder from a tilt sensor sensor connected to the tilt cylinder of the ripper; the reading of a position of the lift cylinder from a stroke sensor connected to the lift cylinder of the ripper; the F.rhalt a lifting cylinder command of the ripper of a stroke control device of the operator; the generation of an automatic pitch cylinder command of the ripper for maintaining the tilt angle of the ripper on the attitude to be maintained inclination upon execution of the lift cylinder command dos rippers; the execution of the automatic tilt cylinder and lift cylinder command of the ripper; and the return to receive another command.

    NACHGEREK
    At least one of the ribbing cylinders (230), (240) is equipped with a sensor for the position of the tilting cylinder (234). The tilt cylinder position sensor (234) senses the position of the piston (232) in the tilt cylinder (230) and sends a sensor output to the EH controller of the ripper (202). The EH control of the ripper (202) may utilize the output of the position of the tilt cylinder (234) to determine the incline and position of the ripper relative to the tractor's primary geometry.
    The Ripper's EH controller (202) processes the operator and sensor inputs and sends control signals to the poppet valve (250) and the tilt poppet valve (260). The spool valve (250) includes a first motion trigger (252) and a second motion trigger (254) to bring the spool valve (250) to a desired position. The spool valve (250) also includes an input side (bottom) connected to a flow source P., for example, a pump, and an output side (top), which is connected to the Hubzylindcm (210), (220). The first motion trigger (252) may be used to move the poppet valve (250) to retract the lift cylinders (210), (220). The second motion trigger (254) may be used to move the pinch valve (250) to extend the lift cylinders (210), (220). The tilt slide valve (260) includes a first motion trigger (262) and a second motion trigger (264) to bring the tilt slide valve (260) to a desired position. The tilt slide valve (260) also includes an inlet track (top) connected to a flow source P, for example, a pump, and an output side (below) connected to the tilt cylinders (230), (240). The first movement trigger (262) may be used to move the tilt slide valve (260) about the tilt cylinders (230). (240) retract.

    Tilt cylinders (234) are processed by a cylinder position processor (304) which also uses the geometric relations table (306) to determine position and pitch data of the ripper. The position and slope data computed by the position processor 304 are sent to an operator command processor 302 and to a position boundary processor 310.
    The operator's command input processor (302) processes the position and tilt data of the ripper provided by the position processor (304) along with inputs from the operator lift, tilt and tilt hold control (204), (206), (208) and the geometric table Relationships (306) to initiate commands for lift and tilt cylinders and to maintain tilt. The lift and tilt cylinder commands, as well as the signals for the tilt to be maintained, are sent to the position limit processor (310).
    The position limit processor (310) processes the inputs of the operator command processor (302) and the position processor (304) and uses the table of geometric relationships (306) to specify commands to lift and tilt cylinders and send them to an output conditioning processor (312). If the option for the ripper to be attached is active, the
    Position limiting processor (310) must revise the input commands from the task command processor (302) before sending them to the output conditioning process (312), in an exemplary embodiment. The operator-adjustable, automatically-held incline allows the operator to set the rib inclination to a desired grade, and the system will maintain this inclination when issuing ripper-stroke commands using the elevator control unit (204). In this embodiment, when the operator with the inclination control (206) changes the inclination angle of the ripper, the system executes the inclination command and sets the new inclination angle as the inclination angle to be taught. For example, the operator could first read the angle of the ripper at 12 degrees and suspend this tilt. while raising or lowering the rib, then use the inclination (206) to change the rib angle to 15 degrees and maintain this new slope when raising and lowering the rib. NAC HG Er ";
    In another exemplary embodiment, the automatic hold function of tilting is fixed, the operator can locate the ribbing to a desired tilt position, the system maintaining this tilt angle when issuing ripper commands with the lift or tilt controls (204), (206). In this embodiment, when the inclination control (206) is operated to change the incline angle of the ripper, the system does not execute the incline command and maintains the incline angle of the ripper at the previous inclination angle. For example, the operator could set the incline angle to be maintained at 12 degrees because it is optimal for ripping a particular material and maintaining this inclination during ripper raising and lowering, and when the tilt control 206 is inadvertently actuated the system ignores the tilt control and maintains the tilt angle of 12 degrees. Of course, with the tilt hold control (208), the operator may disable the fixed tilt hold option or set a new tilt angle rather than the 12 degree tilt, with the system maintaining the new tilt angle.
    The two tilt retention functions described above may be combined in a single system. For example, the ripple hold-in selector (208) may include a selector switch, button, menu, etc., where the operator may set the tilt auto-hold mode: an operator adjustable mode for maintaining rippling angle on ripper lift commands. and changing the incline in ripple command, and a fixed mode to maintain the ridge rotation angle for both ripper-up and tilt commands.
    The output conditioning processor (312) sends commands received from the position limiting processor (310) to the poppet valve (250) and tilt poppet valve (260). The output conditioning processor (312) sends commands for lifting to the motion triggers (252). (254) to position the spool valve (250) and the lift cylinders (210). (220) to control. The output conditioning processor (3 12) sends request strobes to the motion triggers (262). (264) to position the tilt slide valve (260) and the tilt cylinders (230). (240) to control. nachgere;

    At block 422, the system checks if the ripple hold option is still activated. If the ripple hold option is not yet activated, then the idle cylinder command is executed at step (406) and control is returned to block (402) and waits until the ripple hold option is re-activated. If the ripple hold option is still activated, control is directed to block (424).
