Note that the application screen M2 in FIG. 2 shows a farm support application screen. On this application screen M2, a work plan performed by a farmer, that is, a work plan described later can be displayed. The setting screen M3 displays information related to settings of the display device 12 and the like.

FIG. 3 shows an application screen M2 after starting the farm work support application. Here, the farm work support application is software that supports the operation (maneuvering) of the agricultural machine by displaying the traveling state of the agricultural machine (tractor) and the like. That is, after the application is activated, the display device 12 operates as a support device (driving support device) that supports the operation of the agricultural machine.
Next, the case where the display device 12 operates as a driving support device will be described in detail.

  As shown in FIG. 3, when the display device 12 is operated as a driving support device, the application display area 48 of the application screen M2 mainly includes a first display area 48a, a second display area 48b, and a third display. It is divided into regions 48c. In the first display area 48a, a direction display unit 50 and a deviation amount display unit 51 are displayed. A field display section 52 is displayed in the second display area 48b. In the third display area 48c, the remaining amount (theoretical remaining amount) obtained by the calculation unit 25 is displayed in numbers and letters. The display device 12 can also be applied when the remaining amount is not displayed. In this case, the third display area 48c may not be provided.

  The direction display unit 50 is a portion indicating that the position of the traveling vehicle body 3 (the position of the tractor 1) obtained based on the satellite signal from the positioning satellite 15 is shifted from a predetermined reference position. . The reference position can be set by the field display unit 52 as will be described later. The direction display unit 50 indicates, for example, that the current position of the traveling vehicle body 3 is shifted to the left from the reference position or that the current position of the traveling vehicle body 3 is shifted to the right from the reference position.

The deviation amount display unit 51 is a part that displays a deviation amount between the position of the traveling vehicle body 3 and the reference position by a numeral or the like. For example, when the amount of deviation between the current position of the traveling vehicle body 3 and the reference position is 0.5 m, “0.5 m” indicating the amount of deviation is displayed.

Further, when the traveling vehicle body 3 is shifted to the right from the reference position, the other direction display unit 50b indicates that the traveling vehicle body 3 is shifted to the right from the reference position. Therefore, in this embodiment, the direction in which the traveling vehicle body 3 is shifted from the reference position matches the arrow of the direction display unit 50 (one-direction display unit 50b, other-direction display unit 50c).

The reference display unit 50a is located between the one-direction display unit 50b and the other-direction display unit 50c. In other words, the shift amount display unit 51 is located between the one-direction display unit 50b and the other-direction display unit 50c.
The one-direction display unit 50b and the other-direction display unit 50c simultaneously display the magnitude (degree) of the shift amount together with the shift direction when indicating the shift direction. Specifically, the one-way display unit 50b can display the magnitude (degree) of the deviation amount in stages while showing the direction of deviation, and a plurality of one-way arrows indicating that the deviation is in one direction.

The first arrow portion 50b1 indicates that the amount of deviation is the smallest stage. If the amount of deviation exceeds a predetermined value and is equal to or less than the predetermined value, the display color becomes dark (increases saturation and lightness). ). The fifth arrow portion 50b5 indicates that the amount of deviation is the largest, and if the amount of deviation is greater than or equal to a predetermined value, the display color becomes darker. The second arrow part 50b2, the third arrow part 50b3, and the fourth arrow part 50b4 have a deviation amount exceeding a predetermined value and a predetermined value at a stage between the smallest stage and the largest stage. If it is below, the display color becomes dark.

  FIG. 5 shows a change in the display state of a plurality of unidirectional arrow portions of the unidirectional display portion 50b. As shown in FIG. 5, when the position of the traveling vehicle body 3 is shifted to the left from the reference position and the amount of deviation is 0.5 m or less, the display color of the first arrow portion 50b1 is dark. If the position of the traveling vehicle body 3 is shifted to the left from the reference position and the amount of deviation is more than 0.5 m and 1.0 m or less, the display colors of the first arrow part 50b1 and the second arrow part 50b2 are dark. If the position of the traveling vehicle body 3 is shifted to the left from the reference position and the amount of deviation exceeds 1.0 m and is 1.5 m or less, the display colors of the first arrow part 50b1, the second arrow part 50b2, and the third arrow part 50b3 are It becomes darker. If the position of the traveling vehicle body 3 is shifted to the left from the reference position and the amount of deviation exceeds 1.5 m and is equal to or less than 2.0 m, the first arrow portion 50b1, the second arrow portion 50b2, the third arrow portion 50b3, and the fourth arrow The display color of the part 50b4 becomes darker. If the position of the traveling vehicle body 3 is shifted to the left from the reference position and the displacement amount exceeds 2.0 m, the first arrow part 50b1, the second arrow part 50b2, the third arrow part 50b3, the fourth arrow part 50b4, and the fifth arrow part The display color of 50b5 becomes darker. In other words, the display state of the plurality of one-way arrow portions in the one-way display portion 50b changes in increments of 0.5 m. The threshold value (predetermined value) of the deviation amount for darkening the display color of the arrow part, that is, the degree of deviation amount is, for example, the work width performed by the work device 2 or the width of the traveling vehicle body 3. You may set based on the ratio of deviation | shift amount, and you may carry out by the method of other than that.

  The other direction display part 50c can display the magnitude | size (degree) of deviation | shift amount in steps, showing the direction of deviation, and has the some other arrow part which shows that it has shifted | deviated to another direction. . The display state (color density) of the plurality of other-direction arrow portions changes according to the amount of deviation. The plurality of other-direction arrow parts include a first arrow part 50c1, a second arrow part 50c2, a third arrow part 50c3, a fourth arrow part 50c4, and a fifth arrow part 50c5.

  The first arrow portion 50c1 indicates that the amount of deviation is the smallest, and if the amount of deviation exceeds a predetermined value and is equal to or less than a predetermined value, the display color becomes dark. The fifth arrow portion 50c5 indicates that the amount of deviation is the largest, and the display color becomes darker if the amount of deviation is greater than or equal to a predetermined value. The second arrow part 50c2, the third arrow part 50c3, and the fourth arrow part 50c4 are stages between the smallest stage and the largest stage of the deviation amount, and the deviation amount exceeds a predetermined value and If it is below the predetermined value, the display color becomes dark.

  Therefore, when the position of the traveling vehicle body 3 is shifted to the right from the reference position, the first arrow part 50c1, the second arrow part 50c2, the third arrow part 50c3, the fourth arrow part 50c4, Similar to the unidirectional display unit 50b, the display color of the 5-arrow unit 50c5 changes according to the amount of displacement. That is, the display state of the plurality of other-direction arrow portions is the same as that of the plurality of one-way arrow portions except for the shift direction.

  As described above, according to the direction display unit 50, the one-direction display unit 50b (the first arrow unit 50b1, the second arrow unit 50b2, the third arrow unit 50b3) according to the amount of deviation between the position of the traveling vehicle body 3 and the reference position. The display state of the fourth arrow part 50b4 and the fifth arrow part 50b5) changes. Therefore, it is possible to intuitively check how much the degree of deviation of the traveling vehicle body 3 in one direction is by looking at not only the numerical value displayed on the deviation amount display unit 51 but also a plurality of arrow parts. Moreover, according to the direction display part 50, the display state of the other direction arrow part 50c changes according to the amount of deviation. Therefore, not only the numerical value displayed on the deviation amount display unit 51 but also a plurality of arrow parts can be used to intuitively confirm how much the deviation degree of the traveling vehicle body 3 in the other direction is large.

The plurality of one-way arrow portions and the plurality of other-direction arrow portions are arranged linearly. Therefore, the space for arranging multiple arrow parts (multiple one-way arrow parts and multiple other-direction arrow parts) can be reduced as much as possible, and other information is displayed in the area where there is room for space. can do.
A deviation amount display unit 51 is provided between the one-direction display unit 50b and the other-direction display unit 50c.

  Moreover, the direction display part 50 and the deviation | shift amount display part 51 are provided in the same position. That is, the direction display unit 50 and the deviation amount display unit 51 are displayed so as to overlap each other. Therefore, the direction display unit 50 and the shift amount display unit 51 can be viewed at the same focus, that is, both can be viewed without shifting the viewpoint (line of sight). Therefore, it is possible to see at a glance how much and in what direction the position of the traveling vehicle body 3 that is actually traveling deviates from the reference position that is the reference.

  Moreover, the direction display part 50 has the reference | standard display part 50a, the one direction display part 50b, and the other direction display part 50c, and the deviation | shift amount display part 51 is piled up on the reference | standard display part 50a. Therefore, it can be grasped at a glance how much the traveling vehicle body 3 is deviated from the reference position by looking at the reference display portion 50a. Moreover, the direction which has shifted | deviated can be grasped | ascertained only by seeing the one direction display part 50b and the other direction display part 50c which are arrange | positioned on one side and the other centering | focusing on the reference | standard display part 50a. That is, the reference display unit 50a can be regarded as the traveling vehicle body 3, and the position of the traveling vehicle body 3 matches the reference position if the numerical value of the deviation amount display unit 51 displayed in the reference display unit 50a is zero. If the numerical value of the deviation amount display unit 51 displayed in the reference display unit 50a is other than zero, it can be understood that the position of the traveling vehicle body 3 and the reference position are misaligned, and the current position of the traveling vehicle body 3 can be easily determined.

That is, in the above-described embodiment, the direction of deviation of the traveling vehicle 3 and the direction of the arrow portion indicated by the direction display unit 50 are matched. Instead, as shown in FIG. 8B, the deviation of the traveling vehicle 3 with respect to the reference position (for example, the first reference line L1) may be indicated by the other direction display unit 50c instead of the one direction display unit 50b. That is, the direction display unit 50 may indicate the deviation of the traveling vehicle 3 with respect to the reference position by an arrow part (for example, right) that is opposite to the direction of the deviation (for example, left). That is, in FIG. 8B, the direction of deviation indicated by the direction display unit 50 (the direction indicated by the arrow) indicates the direction in which the traveling vehicle body 3 is returned to the reference position. Therefore, the present invention is also applied to the direction display unit 50 that indicates the direction in which the traveling vehicle body 3 is returned to the reference position, that is, the direction display unit 50 that indicates the direction opposite to the direction of deviation of the traveling vehicle 3 with respect to the reference position.
