White pentagons indicate vehicles traveling in a platoon, and hatched pentagons indicate vehicles not intended for the platoon.

[0021] In the following description, the direction of travel of the vehicles can be referred to as the "forward direction." Furthermore, the area between a leading and a trailing vehicle, organized in a platoon traveling in a line in the direction of travel, is referred to as the "intermediate vehicle area." Additionally, a leading vehicle can be referred to as the "host vehicle." Furthermore, a vehicle that has entered the intermediate vehicle area is referred to as the "external vehicle."

[0022] It is assumed that the device 1 is provided to display vehicle information in the host vehicle. Furthermore, the display section 6The information is located in the rear area (e.g., the tailgate or rear frame of a van) of the host vehicle. Furthermore, the information regarding the entry procedure is visual, such as "Enter".

[0023] The section 4 For object detection, an object is detected in the vehicle's intermediate area between the host vehicle (front vehicle) and a rear vehicle. The detection section 51 captures a result of the object capture section 4 The tax section 5 calculated based on the recognition result of the object recognition section 4 Object location information.

[0024] The recording section 51 captures the location result (vehicle location information) of the satellite location segment 3 The investigation section 52 compares the results based on the object recording section.4 calculated object position information combined with the positioning result (vehicle position information) of the satellite tracking segment 3 , to determine whether an external vehicle not intended for the platoon is in the vehicle space.

[0025] If it is detected that an external vehicle has entered the area between the vehicles, the control section sends 5 the information on how to handle the vehicle that has entered the vehicle is displayed in the display section 6 The display section 6 It receives the information and displays it. Since the display section 6 Located in the rear of the host vehicle, the display section 6 The displayed entry information can be visually recognized from the external side of the vehicle.

[0026] Next, a method for determining the break-in period according to the embodiment of the present disclosure is described with reference to Fig. 3 described. Fig. Figure 3 is a flowchart of an exemplary procedure for determining the entry point according to the embodiment of the present disclosure. The procedure of the flowchart is expediently started during a platoon run by vessels organized in a platoon.

[0027] First, in which Fig. Step 3 S100, as shown, captures the acquisition section 51 a recording result from the object recording section 4 .

[0028] Next, in step S110, the investigation section determines 52 based on the recording results of the object recording section 4The procedure checks whether an object has been detected. If an object has been detected (step S110: YES), the procedure continues to step S120. If no object has been detected (step S110: NO), the procedure is aborted.

[0029] In step S120, the control section calculates 5 the object position information based on the recognition result of the object recognition section 4 .

[0030] Next, in step S130, the data collection section records 51 the measurement information (vehicle location information) of the satellite tracking section 3 .

[0031] Next, in step S140, the investigation section compares 52The object position information and the vehicle position information are used to determine whether there is an external vehicle that has entered the area between the vehicles. If there is an external vehicle that has entered the area (step S140: YES), the procedure continues to step S150. If there is no external vehicle that has entered the area (step S140: NO), the procedure ends.

[0032] In step S150, the section generates 53 For information generation, information for handling the entry, which indicates the occurrence of an external vehicle entering the vehicle space.

[0033] Next, in step S160, the execution section 54 To control the information provision, a control system is used that manages the display section 6 prompted the display of information regarding the handling of the entry.

[0034] The vehicle information provision device1 The present embodiment includes the investigation section 52 , which is set up to determine whether there is an external vehicle that has entered the platoon and is not intended for the platoon in the vehicle inter-area, which is an area located between vehicles that are organized in a platoon and travel in succession, an information generation section 53 , which is set up to generate entry handling information for handling the crossed external vehicle when the investigation section 52 Determined that there is a driven-in external vehicle and a display section. 6, which is configured to display entry handling information. Displaying this information notifies the external vehicle to leave the vehicle gap. Once the external vehicle has left the vehicle gap, the vehicles can travel with a reduced vehicle-to-vehicle distance, thus improving fuel efficiency.

[0035] Next, a modification of the present embodiment will be described.

[0036] When an external vehicle is positioned within the vehicle gap—an area enclosed by vans lined up in a front-to-back direction—the information regarding the handling of the lane change is transmitted to the external vehicle. However, if, for example, an external vehicle changes lanes from its own lane to an adjacent lane, vans to the front and rear of the external vehicle significantly obstruct its view, making it difficult for the external vehicle to change lanes.

[0037] In view of this, the section generates 53 In accordance with the modification, additional information is generated to support the lane change of the external vehicle. More precisely, the section generates 53For information generation, a lane change signal is provided, specifying an area for the lane change of the external vehicle. In the present embodiment, the detection section captures 51 a measurement result from the satellite positioning section 3 (Here, the location information of a vehicle in the adjacent lane). Based on the position information of a vehicle in the adjacent lane, the control section calculates 5 the distance Df1 between an external vehicle and a preceding vehicle (the external vehicle and the one in Fig. 2. The first vehicle shown from the front in the adjacent lane) in the direction of travel of the vehicle. In addition, the control section calculates 5 Based on position information from a vehicle in the adjacent lane, the distance Drl between an external vehicle and a rear vehicle (the external vehicle and the rearmost vehicle in the lane) is calculated. Fig.2 adjacent lanes shown) in the direction of vehicle travel.

[0038] The control section 5 The control section determines the distance D between the front and rear vehicles as lane-change information by adding the distances Df1 and Df2. 5 sends the lane change information to the display section 6 The display section 6 Displays the transmitted lane change information.

[0039] The device 1 The provision of vehicle information according to the modification can support the lane change of the external vehicle by providing lane change information for the external vehicle side, thus increasing the ease of the lane change of the external vehicle.

[0040] It should be noted that in this modification, the auxiliary information is the lane change information, which specifies an area in which the external vehicle can move when changing lanes. However, the auxiliary information can also include information about the road ahead and behind a platoon. The information about the road ahead and behind a platoon is provided by the section 53 to generate information based on the position information of the vehicles organized in the platoon and the position information of the vehicles in an area around the platoon.

[0041] Furthermore, the auxiliary information can include information indicating the timing for the external vehicle's lane change. For example, providing information that specifies a suitable or unsuitable timing for the lane change on the external vehicle's side increases the ease of the lane change.

[0042] Furthermore, the additional information can trigger an automatic lane change. If the timing is suitable for the lane change, a vehicle can, for example, be safely separated from a platoon by generating a trigger for a vehicle equipped with an automatic operating function that includes the lane change function.

[0043] Note that, during the section 3In the present embodiment, satellite positioning is used as a positioning device to measure the vehicle position; the positioning device is not located in section 3 is limited to satellite positioning and may be a vehicle speed sensor, a yaw rate sensor, a component that performs positioning by so-called dead reckoning navigation based on data from a steering angle sensor, or a component that uses a beacon and the like.

[0044] In the present embodiment, a millimeter wave sensor serves as the object detection section. 4 It is also possible to use a laser sensor, an ultrasonic sensor, or a camera that captures an image of an object.

[0045] During the display section 6 In the present embodiment, the display section is arranged in the rear wall of the host vehicle. 6It may also be located in an external vehicle. The display section 6 The operating display section, which is located in an external vehicle, can be such as a touch panel display. In this case, the execution section performs the following actions. 54 To control the provision of information, a control system is used which includes the section 2 This prompts the system to initiate cross-vehicle communication with the external vehicle. Lane change information, for example, is transmitted from the host vehicle via the cross-vehicle communication segment. 2 provided to the external side of the vehicle. Furthermore, the display section located in an external vehicle 6 a mobile device that can be installed in an external vehicle, such as a tablet terminal (pad terminal), a personal computer, and a smartphone.

[0046] During the display section 6 In the present embodiment, the display section is used as a notification section that communicates information about the entry treatment to the external vehicle side in the form of visual information. However, it is also possible to use a sound generator, such as a buzzer and a loudspeaker, to communicate information about the entry treatment to the external vehicle side in the form of sound. It should be noted that both the display section 6 as well as the tone generator.
