The work vehicle 10 of the illustrated embodiment also includes an operator station 18 configured to include, position, or otherwise position an operator 20 to operate the work vehicle 10. In the illustrated embodiment, the operator 20 uses one or more vehicle control units 26 to control the work vehicle 10, the work tool 12, and / or any other aspect of the work vehicle 10 from an operator position 22 located in or at the operator station 18. The vehicle control units 26 include, but are not limited to, a steering wheel, a joystick, and / or another interface or engagement device. In the illustrated embodiment, the operator station 18 includes columns 24 supporting one or more portions of the operator station 18.
[0015] An object indication system 30 is included in one or more embodiments of this disclosure. The system 30 is configured to indicate to the operator 20 of the work vehicle 10 the relative position of an object 32 located at a distance 34 from the work vehicle 10. In embodiments, the relative position of the object 32 refers to the position of the object 32 relative to the work vehicle 10. In additional embodiments of this disclosure, the relative position of the object 32 refers to the position of the object 32 relative to one or more sensors, other objects, individuals, base stations, or other locations.
[0016] Figure 1 The system 30 of the illustrated embodiment includes a plurality of sensors 36 located at or configured to be located at a plurality of sensor positions 38 on the work vehicle 10. The sensors 36 sense or are configured to sense the object 32. The sensors 36 of the illustrated embodiment include ultrasonic sensors, but the sensors 36 include one or more infrared, laser, or radar-based object sensing devices or systems, or any other object sensing devices or systems in additional embodiments of this disclosure. The sensor positions 38 of the sensors 36 in the illustrated embodiment are located at the operator station 18 and / or as shown in the figure. Figure 1 The rear end 28 shown in the diagram is located on or at the operator station 18 and / or as shown in the diagram. Figure 1 The sensor location 38 is shown at the rear end 28 in the diagram, but in other embodiments, the sensor location 38 may be located elsewhere, including on or at the front end 14, the working tool 12, and / or any other part of the working vehicle 10. Figure 1 As illustrated, the sensor 36 is distributed at sensor position 38 relative to the position of the operator 20. The sensor 36 is oriented away from the operator station 18, the operator 20, and / or the work vehicle 10, and is configured to sense the object 32. The object 32 in one or more embodiments includes any one or more fixed or movable objects, obstacles, boundaries, or other physical anomalies surrounding the area of the work vehicle 10. In a non-limiting example, the object 32 includes another vehicle approaching the work vehicle 10, which the work vehicle 10 and / or the system 30 can sense and indicate to the operator 20 so that the operator 20 can control the work vehicle 10 away from the object 32. In an additional embodiment not illustrated, there are multiple objects 32 located at different positions relative to the work vehicle 10, which the work vehicle 10 and / or the system 30 simultaneously and / or separately sense and indicate to the operator 20. As depicted in the embodiments herein, the term "object" as included in any embodiment refers to any one or more objects sensed by the work vehicle 10 or the system 30.
[0017] One or more embodiments of the work vehicle 10 and / or the system 30 include a controller 46. In one embodiment, the controller 46 receives or is configured to receive one or more sensor signals from the sensors 36. The controller 46 and / or the sensors 36 associate each signal transmitted by each sensor 36 with the sensor position 38 of the sensor 36. In one embodiment, the sensor signal includes a signal distance value representing a distance 34 between the sensor 36 and the object 32. Thus, in at least one embodiment, the controller 46 receives or otherwise determines a signal position value and a signal distance value, the signal position value being based on the sensor position 38 of the signal transmitting sensor 36, and the signal distance value being based on the distance 34 between the sensor 36 and the object 32 sensed by the signal transmitting sensor 36. Figure 1As illustrated, the main signal transmitting sensor 50 senses the distance 34 between itself and the object 32 and transmits its signal distance value to the controller 46. In an additional embodiment, a secondary sensor 52, located adjacent to or close to the main sensor 50, can also sense the object 32 and provide discrete distance values associated with a corresponding sensor position 38 of the secondary sensor 52. The controller 46 receives or otherwise determines a signal position value having the signal distance values received from the main sensor 50 and the secondary sensor 52.
[0018] like Figure 1 and Figure 2 As shown, the system 30 in some illustrated embodiments further includes a plurality of indicators 40 positioned or configured to be positioned at a plurality of indicator positions 42 corresponding in direction to the sensor position 38. In a non-limiting example, the indicators 40 of embodiments of this disclosure provide visual, audible, and / or tactile or physical indications to one or more work vehicle controls 26, such as through vibration or motion feedback. The indicators 40 are activated based on sensing of the object 32, or are configured to be activated based on sensing of the object 32. In the illustrated embodiment, the indicators 40 are distributed at the indicator positions 42 located in, on, or otherwise at the operator station 18. In the embodiment, the indicator positions 42 correspond to the sensor position 38 to indicate the relative position of the object 32 to the operator 20. In other words, each of the indicator positions 42 is aligned with, positioned adjacent to, and / or corresponds to one or more of the sensor positions 38, such that the operator 20 associates the indication from the indicator 40 with the aligned, adjacent, or otherwise corresponding or associated sensor 36. Therefore, the operator 20 can receive indications of the position of the object 32 and / or the distance 34 of the object 32, for example, from the work vehicle 10.
[0019] In embodiments of this disclosure, each of the plurality of sensors 36 is configured to sense a distance 34 of the object from a corresponding sensor position 38 of the plurality of sensor positions 38. Each of the plurality of indicators 40 is configured to activate based on the distance 34 of the object 32 from the corresponding sensor position 38.
[0020] In embodiments of this disclosure, different numbers of indicators 40 are activated based on a distance 34 of the object 32 sensed from a corresponding sensor position 38. In a non-limiting example, a larger number of indicators 40 are activated when one of the sensors 36 senses that the object 32 has moved or has otherwise been positioned closer to the sensor 36. In a particular embodiment, a first number of the plurality of indicators 40 are configured to be activated based on a first distance of the object 32 from a corresponding sensor position. In a non-limiting example, three adjacent indicators 40 are activated based on the object 32 being within ten meters of the sensor 36, the sensor 36 having a sensor position 38 corresponding to the position of the indicator 40 located at the center of the three adjacent indicators 40. A second number of the plurality of indicators 40 are configured to be activated based on a second distance of the object 32 from a corresponding sensor position. In the non-limiting example, five adjacent indicators 40, or two additional indicators 40 at each end, are activated based on the object 32 being within five meters of the sensor 36. The sensor 36 has a sensor position 38 corresponding to the position of the indicator 40 located at the center of the five adjacent indicators 40. In a similar embodiment, as the position of the object 32 changes relative to each sensor position 38, other sensors 36 or groups of sensors 36 can be activated and / or deactivated to indicate the relative position and / or distance of the object 32 from the work vehicle 10. In a non-limiting example, an illustrative embodiment of the indicator 40 may include a series of lights aligned on a rope light or similar configuration. Various embodiments of the indicator 40 described herein may be implemented on a light strip; or via a similar configuration; or via a visual or auditory indicator 40 (referred to as a non-limiting example) installed on, in, or at the operator station 18 (such as adjacent to or around the operator 20), or on one or more pillars 24, at or adjacent to one or more bases of windows in the operator station 18, and / or at or adjacent to the edge of the roof of the operator station 18.
[0021] In various embodiments of this disclosure, the output of each of the plurality of indicators 40 is varied based on, or configured to vary based on, the distance 34 of the object 32 from the corresponding sensor position 38. In some embodiments, the plurality of indicators 40 visually indicate based on sensing the presence or position of the object 32, or are configured to visually indicate. In a non-limiting example, one or more of the indicators 40 are lamps that illuminate respectively to visually indicate the presence or position of the object 32. In another non-limiting example, the output, as the light intensity from each lamp, is modulated or varied based on the distance 34 of the object 32 from the corresponding sensor position 38.
[0022] In some embodiments, the plurality of indicators 40 provide audible indication or are configured to provide audible indication based on sensing the presence or location of the object 32. In a non-limiting example, one or more of the indicators 40 are transducers or loudspeakers that are respectively actuated to generate pulses, vibrations, or sound waves to audibly indicate the presence or location of the object 32. In another non-limiting example, the output transducer, as the volume or actuation intensity from each transducer or loudspeaker, is modulated or altered based on the distance 34 of the object 32 from the corresponding sensor position 38.
[0023] like Figure 3As illustrated in the figure, in an embodiment of this disclosure, the system 30 includes an interface member 60 coupled to or configured to be coupled to the operator 20 of the work vehicle 10. The interface member 60 includes one or more indicators 40 as described in one or more embodiments herein, the one or more indicators 40 being positioned or configured to be positioned in, on, or at the interface member 60 to indicate to the operator 20 of the work vehicle 10 the position of the object 32 relative to the operator 20. In the illustrated embodiment, the interface member 60 includes glasses 62, headphones 64, jaw interaction device 66, headwear, another device, and / or any combination thereof, these interface members 60 being mounted on, to, or at the operator 20, or mounted adjacent to the operator 20, to include, mount, support, or otherwise provide one or more of the indicators 40 for visual or auditory indication according to any embodiment described herein. Additionally, in the illustrated embodiment, the interface component 60 may include augmented reality and / or interactive features or functions to provide engagement with the operator 20 and / or one or more auditory or visual cues. In a non-limiting example, the right and left lenses of the interface component 60 may include one or more lights or other visual indicators that are activated and / or modulated based on the presence and / or position of the object 32 on the right or left side of the operator 20 and / or the work vehicle 10. Similarly, in another non-limiting example, the right and left earpieces of the interface component 60 may include one or more speakers 70, transducers, or other auditory indicators, each of which is activated and / or modulated based on the presence and / or position of the object 32 on the right or left side of the operator 20 and / or the work vehicle 10. Any indicator 40 (e.g., an indicator 40 installed in or on the operator station 18 and in or on the interface member 60, as described in the various embodiments of this disclosure) or indication function can be used interchangeably and / or in conjunction with other indicators 40 or indication functions.
[0024] In another embodiment, the system 30 and / or the work vehicle 10 includes a dynamic adapter that modulates or alters, or is configured to modulate or alter, indications made by the indicators 40 and / or other operations of the system 30 and / or the work vehicle 10, based on previous or historical inputs from observed, sensed behavior of the operator 20, or other inputs from behavior of the operator 20 following a previous indication event. In embodiments of this disclosure, the system 30 and / or the work vehicle 10 includes one or more operator sensors, instruments, and / or one or more control input devices, one or more data storage devices, and / or one or more controllers to receive inputs of the operator 20's behavior or other data related to the operator 20, and based on the inputs, to send outputs to separate controllers or one or more of the indicators 40. In a non-limiting example used for illustration, the output from the dynamic adapter is based on an input that indicates that the operator 20 has not responded adequately to previous instructions from one or more indicators 40 due to insufficient or lack of changes to the vehicle controls of the work vehicle 10. Data input to the dynamic adapter may be stored, processed, and / or used by the dynamic adapter and / or another controller in the form of a model, or stored, processed, and / or used using algorithms for the operation of the dynamic adapter, the larger system 30, and / or any other operation of the work vehicle 10 or any other system.
[0025] Now refer to this disclosure Figure 3 This disclosure also provides a method 100 for instructing the operator 20 of the work vehicle 10 on the relative position of an object 32 located at a distance 34 from the work vehicle 10. The method 100 includes, at step 110, sensing the object 32 by one or more sensors 36 positioned at one or more of the plurality of sensor locations 38 on the work vehicle 10. The method 100 further includes, at step 112, activating one or more indicators 40 positioned relative to the operator 20 at one or more indicator locations 42 based on the sensing of the object 32 by the one or more sensors 36. Each of the sensor locations 38 is positioned adjacent to, aligned with, or oriented in a manner corresponding to or otherwise corresponding to the one or more indicator locations 42, in order to indicate the relative position of the object 32 to the operator 20 of the work vehicle 10.
[0026] The method 100 of a particular embodiment further includes: sensing the object 32 by the one or more sensors 36 by sensing a distance 34 between the object 32 and the one or more sensors 36; and activating the one or more indicators 40 based on the distance 34 of the object 32. As discussed in further detail above, the method 100 of the embodiment further includes: activating a first number of indicators 40 among the one or more indicators 40 based on a first distance of the object 32; and activating a second number of indicators 40 among the one or more indicators 40 based on a second distance of the object 32. In the embodiment, the first number of indicators 40 among the one or more indicators 40 is different from the second number of indicators 40 among the one or more indicators 40. Also described in further detail above, the method 100 of the particular embodiment may further include: modulating or changing the output of the one or more indicators 40 based on the distance 34 of the object 32, for example, changing the light intensity for visual indication, or changing the amount, frequency, or other characteristics or output of sound or vibration for auditory indication. Any details, features, or functions of the work vehicle 10 or system 30 constitute part of one or more embodiments of the method 100 of this disclosure.
[0027] Without limiting the scope, interpretation, or application of the claims described below in any way, it will be understood that the work vehicle 10, the system 30, and the method 100 of the embodiments of this disclosure improve the operator 20's ability to identify (one or more) the object 32 and / or determine the location and / or distance 34 of the object 32. By providing visual and / or auditory cues to the operator 20 when one or more of the object 32 is sensed approaching the work vehicle 10, the visual and / or auditory cues can reduce or minimize disturbances to the tasks, controls, and operations performed by the operator 20. Additionally, the indicator 40 can increase the operator 20's alertness, regardless of whether the operator 20 has noticed any (one or more) object 32. Finally, the work vehicle 10, the system 30, and the method 100 improve the operator 20's perception of one or more of the objects 32 under certain conditions or events that affect the operator 20's ability to detect the area of the work vehicle 10 or the area around the work vehicle 10 (such as during periods of excessive activity, noise, light, darkness, and / or dust / debris).
