FIG. 5 is a drawing illustrating a screen for displaying a process of controlling to form a platoon according to an exemplary embodiment of the present disclosure. Referring to FIG. 5, a user may select and drag and drop a host vehicle for joining a platooning line onto a desired location to form a platoon. In reference numeral 501 of FIG. 5, an exemplary embodiment is exemplified as the host vehicle joins the tail end of following vehicles. Referring to reference numeral 502, a platooning controller 100 of FIG. 1 may be configured to display following vehicle FV4 added to the location dragged and dropped by the user on a display 400 of FIG. 1 and display a question and answer screen, such as reference numeral 503, for requesting whether to form a platoon, on the display 400.
Thus, the platooning controller 100 of following vehicle FV4 may be configured to request the leading vehicle LV1 to form a platoon. A question and answer screen, such as reference numeral 504, for requesting approval to form the platoon may be displayed on a screen of a display of leading vehicle LV1. Thus, a user of leading vehicle LV1 may approve the formation of the platoon including following vehicle FV4, and the following vehicle FV4 may join a platooning line. The platooning controller 100 may be configured to operate to blink a vehicle area of following vehicle FV4 like reference numeral 505 while following vehicle FV4 joins the platooning line and stop the blinking when the joining to the platooning line is completed.
Accordingly, when vehicle FV4 which wants to join the platooning line is dragged and dropped by a user, the platooning controller 100 of vehicle FV4 may be configured to determine that the user wants to join the dragged and dropped location in the platooning line and request the leading vehicle LV1 to form a platoon. When leading vehicle LV1 approves the request, vehicle FV4 may join the platooning line. When vehicle FV4 joins the platooning line, the platooning controller 100 may be configured to display a vehicle area of the joined vehicle FV4 displayed on the display 400 in a blinking manner. When the joining to the platooning line is completed, the platooning controller 100 may stop the blinking of the vehicle area.
FIG. 6 is a drawing illustrating a screen for displaying a process of controlling to join a middle location of a platooning line according to an exemplary embodiment of the present disclosure. In FIG. 6, an exemplary embodiment is exemplified as a host vehicle wants to join the middle of a platooning line rather than the end of the platooning line. A user of the host vehicle may touch a vehicle area of the host vehicle like reference numeral 601 and may drag and drop the vehicle area of the host vehicle onto the middle of the platooning line (between following vehicles FV2 and FV3) like reference numeral 602. Like reference numeral 603, a platooning controller 100 of FIG. 1 may be configured to display a question and answer screen for querying the leading vehicle LV1 whether to request to form a platoon.
When the user of the host vehicle touches “Yes”, the platooning controller 100 may be configured to transmit a platoon request message to the leading vehicle LV1. A display of leading vehicle LV1 may be configured to display a question and answer screen, such as reference numeral 604, for approving the request for forming the platoon. When a user of leading vehicle LV1 touches “Yes”, the platooning controller 100 may be configured to display the vehicle area of the host vehicle to be located in the middle of the platooning line, which is the dragged and dropped location. In particular, the vehicle area of the host vehicle may blink (e.g., output in a blinking manner). When the joining to the platooning line is completed, the platooning controller 100 may be configured to stop the blinking.
FIG. 7 is a drawing illustrating a screen for displaying a process of controlling to release a platoon according to an exemplary embodiment of the present disclosure. Like reference numeral 701 of FIG. 7, vehicle areas of leading vehicle LV1 and following vehicles FV1, FV2, FV3, and FV4, which are in platooning, may be sequentially folded and displayed. When a user of following vehicle FV3 touches the vehicle area of following vehicle FV3 on a screen displayed on a display 400 of FIG. 1 like reference numeral 702 and drags and drops the vehicle area of following vehicle FV3 to be moved greater than a predefined distance from a vehicle area of a platooning line or to be moved in a predetermined specific direction (e.g., to a lower location) like reference numeral 703, a platooning controller 100 of FIG. 1 may be configured to determine that the following vehicle FV3 wants to release a platoon and display a question and answer for requesting the leading vehicle LV1 to release the platoon.
Particularly, like reference numeral 703, when following vehicle FV3 gets out of or exits the vehicle area of the platooning line, following vehicle FV4 may be corrected and displayed as following vehicle FV3. When a user touches “Yes” on a question and answer for requesting to release a platoon, the platooning controller 100 may be configured to release the platoon. While the platooning controller 100 releases the platoon, like reference numeral 705, following vehicle FV3 which is releasing the platoon may be displayed as a new vehicle NEW in a blinking manner. When the releasing of the platoon is completed, the platooning controller 100 may be configured to stop the blinking.
FIG. 8 is a drawing illustrating a screen for displaying a process of adjusting a platooning line of a leading vehicle according to an exemplary embodiment of the present disclosure. Referring to FIG. 8, an exemplary embodiment is exemplified as a user of leading vehicle LV1 touches and selects a vehicle (e.g., following vehicle FV3) that is desired to be adjusted in a platooning line, like reference numeral 801, and moves a vehicle area of following vehicle FV3 to a desired location (e.g., between leading vehicle LV1 and following vehicle FV1) like reference numeral 802. Thus, a platooning controller 100 of leading vehicle LV1 may be configured to display a question and answer screen, such as reference numeral 803, for requesting to adjust the platooning line.
When the user of leading vehicle LV1 touches “Yes”, the platooning controller 100 of leading vehicle LV1 may be configured to request following vehicle FV3 to adjust the platooning line. A display of following vehicle FV3 may be configured to output or display a question and answer screen for approving the request for adjusting the platooning line, like reference numeral 804. Thus, when a user of following vehicle FV3 touches “Yes” and approves to adjust the platooning line, the leading vehicle LV1 may be configured to request following vehicle FV3 to adjust the platooning line. A display of following vehicle FV1 may be configured to output or display a question and answer screen, such as reference numeral 805, for approving the request for adjusting the platooning line.
Thus, when following vehicle FV1 approves the adjustment of the platooning line, following vehicle FV3 may move immediately behind leading vehicle LV1 and following vehicle FV1 may move to a third location. Thus, the platooning line in a state where the line is adjusted may be displayed like reference numeral 806 on a display of each platooning vehicle. In particular, a vehicle area corresponding to a host vehicle may be output in a blinking manner while the platooning line is adjusted. When the adjusting of the platooning line is completed, the blinking may be stopped. For example, when a screen such as reference numeral 806 is displayed on a display of following vehicle FV2, a vehicle area of following vehicle FV2 may be output in a blinking manner. When a screen such as reference numeral 806 is displayed on a display of leading vehicle LV1, a vehicle area of leading vehicle LV1 may be output in a blinking manner.
FIG. 9 is a drawing illustrating a screen for displaying a process of adjusting a platooning line of a following vehicle according to an exemplary embodiment of the present disclosure. FIG. 9 illustrates a process of adjusting a platooning line when a host vehicle is following vehicle FV3. Referring to FIG. 9, an exemplary embodiment is exemplified as a user of following vehicle FV3 touches and selects a vehicle area of the host vehicle (following vehicle FV3) like reference numeral 901 and moves the vehicle area of following vehicle FV3 to a desired location (e.g., between leading vehicle LV1 and following vehicle FV1), like reference numeral 902. Thus, a platooning controller 100 of following vehicle FV3 may be configured to display a question and answer screen, such as reference numeral 903, for requesting to adjust a platooning line. When a user of following vehicle FV3 touches “Yes”, the platooning controller 100 of following vehicle FV3 may be configured to request following vehicle FV1 to adjust the platooning line.
A display of following vehicle FV1 may be configured to display a question and answer screen, such as reference numeral 904, for approving the request for adjusting the platooning line. When following vehicle FV1 approves to adjust the platooning line, the platooning controller 100 of following vehicle FV3 may be configured to request leading vehicle FV1 to approve to adjust the platooning line. A display of leading vehicle LV1 may be configured to output or display a question and answer screen, such as reference numeral 905, for requesting to approve to adjust the platooning line. Thus, when a user of leading vehicle LV1 approves to adjust the platooning line, following vehicles FV1 and FV3 may adjust the platooning line. A screen, such as reference numeral 906, for adjusting the platooning line may be displayed on displays of all vehicles included in the platooning line. In particular, while the platooning line is adjusted, the vehicle area corresponding to the host vehicle may be output in a blinking manner on the displays.

Furthermore, in a description of FIGS. 10 and 11, an operation described as being by performed by an apparatus may be understood as being performed by a processor 130 of the platooning controller 100.
In S101, when an FV mode is selected by a user during platooning, the apparatus may be configured to operate a host vehicle to travel in the following vehicle (FV) mode. In S102, the apparatus may be configured to detect a vehicle, capable of playing a role as a leading vehicle (LV) and performing platooning, within a predetermined distance from the front of the host vehicle via vehicle-to-vehicle (V2V) communication while the host vehicle is being driven. In S103, the apparatus may be configured to determine whether following vehicle FV is a vehicle which reserves a platooning schedule in advance. When following vehicle FV is the vehicle which reserves the platooning schedule in advance, in S104, the apparatus may be configured to determine whether the detected leading vehicle LV is the reserved leading vehicle LV.
When the detected leading vehicle LV is the reserved leading vehicle LV, in S105, the apparatus may be configured to display lanes of the host vehicle (following vehicle FV) and leading vehicle LV together with a current lane location of the host vehicle on an HMI screen. In S106, the apparatus may be configured to determine whether a leading vehicle LV and a following vehicle FV are in the same lane. When there are no leading vehicles LV and following vehicles FV in the same lane, in S107, the apparatus may be configured to move following vehicle FV and leading vehicle LV to the same lane to be in a state capable of performing platooning.
When a leading vehicle LV and a following vehicle FV are in the same lane, in S108, the apparatus may be configured to generate a dotted arrow guide between the host vehicle (following vehicle FV) and leading vehicle LV. In S109, a user of following vehicle FV may request to join a platooning line in a drag and drop technique. In S110, the apparatus may be configured to determine whether both of leading vehicle LV and following vehicle FV approve to form a platoon. When both of leading vehicle LV and following vehicle FV approve to form the platoon, in S111, the apparatus may complete the formation of the platoon.
When leading vehicle LV or following vehicle FV does not approve to form the platoon, in S112, the apparatus may be configured to display an error message on the HMI and repeat the request for approval to form the platoon a predetermined number of times. When leading vehicle LV or following vehicle FV does not approve to form the platoon continuously, in S113, the apparatus may be configured to display failure of the platoon joining. Thus, the apparatus may repeat S108 to S113.
Meanwhile, when following vehicle FV does not reserve the platooning schedule in S103 in advance and when leading vehicle LV is detected within a predetermined range of following vehicle FV which does not reserve the platooning schedule in advance, in S201, the apparatus may be configured to display the selected leading vehicle LV (e.g., display all when a plurality of leading vehicles are detected) together with a lane and a host vehicle (following vehicle FV) on the HMI screen.
When there are a plurality of leading vehicles, in S202, the apparatus may be configured to display a final destination and an important path for each leading vehicle on the HMI screen. In S203, a user of following vehicle FV may double-touch or double-click the leading vehicle LV for platoon joining and may query the leading vehicle LV as to whether the following vehicle FV is able to join a platooning line led by leading vehicle LV. In particular, the apparatus may fail to display a guide when querying leading vehicle LV to join the platooning line.
Meanwhile, in S204, the apparatus of leading vehicle LV may be configured to display a path and a final destination of following vehicle FV as a pop-up on an HMI. In S205, leading vehicle LV may be configured to determine whether it is able to approve the request for joining the platooning line. When the request for joining the platooning is granted by leading vehicle LV, the apparatus may perform S106 to S113 of FIG. 10.
Meanwhile, when the request for joining the platooning line is not granted (denied) by leading vehicle LV (e.g., first leading vehicle), in S206, the apparatus may be configured to determine whether there is another leading vehicle within a predetermined distance. When another leading vehicle (e.g., a second leading vehicle) is detected, the apparatus may perform S203 to S206 with respect to the second leading vehicle. In particular, the apparatus may fail to display leading vehicle LV, which denies the request for joining the platooning line, on the HMI, and may be configured to display another new leading vehicle.
Accordingly, an exemplary embodiment of the present disclosure may integrate platooning situations, passively displayed on an on/off switch and a cluster, into one platooning situation and display the integrated one platooning situation on the HMI to provide various commands for each situation and express an intention of the user rather than a simple on/off command, thus efficiently operating platooning control and performing safely control.
