    Automatic work lamp activation and deactivation
    Field of the invention
    This disclosure relates to a system and method for automatically activating and deactivating a work lamp on a vehicle.
    Background of the invention
    Work lights are often used on a construction or other work equipment to illuminate the work area when editing with a tool.
    Summary of the invention
    The invention relates to the lighting for a work vehicle. In particular, the lighting may be turned on for at least a portion of a tool and the work area in its vicinity when such illumination is desired and automatically turned off when such lighting is no longer desired. Circumstances under which illumination may be desired may include, but are not limited to, a need to observe the working range of the tool when the natural or ambient lighting conditions are insufficient for such observations. Conditions under which the lighting may no longer be desirable may be a desire to avoid light reflections to a cab of the vehicle when the tool is in a transport position. Such reflections can affect the view, though
    Ambient lighting conditions, e.g. Night conditions, insufficient lighting.

    FIG. 2 shows the vehicle from FIG. 1 with the working tool in a transport position; FIG.
    FIG. 3 shows the vehicle from FIG. 1 with the working tool in a transport position; FIG.
    Fig. 4 illustrates a block diagram of an embodiment of the invention; and FIG. 5 illustrates a flowchart of an embodiment of the invention. Description of the preferred embodiment
    Fig. 1 illustrates an exemplary work vehicle, i. a dozer 10 having a cab 20, a frame 30 to which the cab 20 is attached, a chassis 40 attached to and supporting the frame 30, a push bar 50 pivotally mounted to the chassis 40 via a push bar axle 51, a setting cylinder 60 which is pivotally mounted on a setting cylinder axis 61 on the push bar 50, a shield 70 which is pivotally mounted on a first shield axis 71 on the push bar 50 and a second shield axis 72 on the adjusting cylinder 60 and a lifting cylinder assembly 100 pivotally about a Lifting cylinder axis 121 is mounted on the frame 30 and a third shield axis 73 on the plate 70.
    As shown in FIG. 1, the lift cylinder assembly 100 may include: a work lamp 110; a hydraulic lift cylinder 120 having a hydraulic lift cylinder shell 120a and a hydraulic lift cylinder rod 120b; and the hydraulic lifting cylinder axle 121 to which the hydraulic lifting cylinder bank 120a may be pivotally mounted. The hydraulic lifting cylinder 120 may include a commercially available position sensor 120c for detecting a position of the hydraulic lifting cylinder 120 and communicating a signal indicative of a length of the hydraulic lifting cylinder 120 when it, the hydraulic lifting cylinder 120, is expanding or contracting. The work lamp 110 may be fixedly attached to the hydraulic lift cylinder bank 120a.
    As previously indicated, FIG. 1 shows the planer 10 with the work implement or shield 70 and work lamp 110 in a working position. As illustrated, when the shield 70 is in the working position, the work lamp 110 may illuminate a portion of the shield 70 as well as a portion of the material on which the shield 70 operates. The material may be soil or any other material that moves the planter 10, e.g. Stones, trash, etc., be.
    Fig. 2 shows the bulldozer 10 with the working tool or the shield 70 in a transport position and the work lamp 110, which emits light. The transport position may include any calculated or measured position of the shield 70 that exceeds a predetermined height, i. a height that is sufficiently above the ground level. In this particular embodiment, the predetermined height may be one (1) feet above the floor of the vehicle B. As illustrated, when the shield 70 is in the transport position, the work lamp 110 may continue to illuminate a portion of the shield 70 but not continue to illuminate a relevant portion of the material. As illustrated, in this particular scenario with continued supply of the work lamp 110, the operator is likely to experience unwanted light reflections from the shield 70 to the cab 20; especially under poor ambient lighting conditions, e.g. natural lighting conditions during night work. 3 illustrates the leveler 10 with the shield 70 in the transport position with the work lamp 110 switched off.
    4 is an exemplary illustration of a control system for the work lamp 110 that uses the invention. As illustrated, the control system may include: push beam angle sensors 52; Lifting position sensors 120c; an electro-hydraulic controller section 130; a vehicle controller section 140; a work lamp control mode selector 150 which may have an automatic control mode and a manual control mode; and a conventional control input device for the work lamp by an operator, such as an operator. a toggle switch 160 which the operator can place in an on state or an off state. The electro-hydraulic controller section 130 may include: an angle processor 131; an angle-to-planter blade position look-up table 132; a lift cylinder length processor 133; a lift cylinder length-to-planter blade position look-up table 134, The vehicle control portion 140 may include: a static storage section 141 including lamp control information from the work lamp control mode selector 150; and a lamp controller 142. The angle look-up table 134 may have some overlap with the lift cylinder length-to-bulldozer position lookup table 132, but if the lift cylinder position sensors 120c are operative, i. Send signals, the lamp controller 142 may respond to information from the lift cylinder length-to-position table 132 and may not respond to information from the push beam angle sensors 52.
    The automatic control mode for the exemplary
    Work lamp control mode selector 150 may provide automatic work lamp operation when the work lamp switch 160 is in an on state. Such an automatic control mode may cause the work lamp 110 to be automatically turned on when the dozer blade 70 is below a predetermined height, or when the dozer blade 70 is at a height equal to or greater than the predetermined height, and turn off conventional vehicle headlights (not shown) are. The automatic control mode may cause the work lamp 110 to be automatically turned off when the dozer blade 70 is at a height greater than the predetermined shield height and the vehicle headlights (not shown) are turned on. The work lamp control mode selector 150 supplies the control modes to be described by sending necessary control information to the vehicle control section 140. In this exemplary embodiment, the work lamp control mode selector 150, which may include predetermined control information for each control mode, sends predetermined work lamp control information to the static memory section 141
    Selecting a control mode via a switch, a monitor menu with a switching mechanism, a touch screen monitor menu, or other conventional arrangement, the static memory section 141 may then provide this information to the lamp controller 142. The lamp controller 142 may then Control the work lamp 110 by using the information provided by the static storage section 141 and the work lamp switch 160.
    The manual control mode for the exemplary work lamp control mode selector 150 may provide manual control of the work lamp, i. when the work lamp switch 160 is in an on state, the work lamp 110 may be on, and when the work lamp switch is in an off state, the work lamp may be turned off.
    FIG. 5 is an exemplary flowchart showing how the exemplary embodiment of FIG. 4 may operate. As shown, the process begins as soon as the ignition is turned on in step 310. Once the ignition is on, the vehicle controller 140 may determine in step 315 whether the automatic mode is selected, i. whether the work lamp mode selector 150 is set to automatic mode. If the automatic mode is selected, the vehicle controller 140 determines in step 320, via the lamp controller 142, whether the work lamp switch 160 is in the on state. If the work lamp switch 160 has been determined to be in the on state in step 320, the height of the sign 70 may be checked in step 330. If the shield 70 is not below a predetermined position in step 330, the headlight of the vehicle 10 may be checked to determine in step 340 whether the headlight is on. If the headlamp is not on in step 340, the work lamp 110 may remain on in step 350 and the vehicle controller 140 may return to step 320. If the headlamp is on in step 340, the work lamp 110 may be turned off in step 360. If the sign 70 is below the predetermined position in step 330, the work lamp 110 may be turned on in step 370, regardless of other conditions, and the vehicle controller 140 may return to step 320. If it is determined that the work lamp switch 160 is in the off state, the work lamp 110 is turned off.
    Having described the preferred embodiment, it will be apparent that various modifications can be made without departing from the scope of the invention as defined in the appended claims.
