Referring to FIG. 1 , a server 100 (hereinafter, referred to as a recommendation server) that provides a group driving recommendation service according to the present embodiment may receive driving information of vehicles currently driving through a network 1000 .

In this embodiment, the target of the group driving recommendation service is not limited to the type of vehicle, and all of the passenger car 200a, the van 200b, the bus 200c, and the truck 200d may be the service target.

The user 10 is a driver who directly drives a vehicle or a person who can assist in driving by riding a vehicle, and may access a network through a user terminal and provide his/her driving information.

The user terminal may be a nomadic device such as a smart phone or tablet PC that the user directly possesses.

Alternatively, an in-vehicle terminal that is mounted in a vehicle and communicates with the recommendation server 100 on a network and provides a service according to the user's authentication is also possible.

That is, in this embodiment, the user provides driving information to the recommendation server 100, and the recommendation server 100 can recommend whether to drive in a group by comparing the driving information of other users currently driving.

In addition, although not shown, a traffic infrastructure (not shown) that additionally provides environmental information such as road traffic information, weather, and other information related to group driving may be included. Hereinafter, a group driving guidance method performed by the recommendation server 100 according to the present embodiment will be described in detail with reference to the drawings.

Referring to FIG. 2 , the recommendation server 100 according to the present embodiment may recommend group driving using driving information of other users that is related to the driving information of the user.

Specifically, group driving may be recommended by comparing the user's driving route information among the driving information with the driving route information of other users.

In this case, other users can drive by forming a new cluster with the recommended user as they are currently driving alone in two ways, or it is also possible to drive by expanding the group by joining the group of users who are already running the group driving.

Alternatively, in the present embodiment, users may share each other's route information within a pre-formed network, and the recommendation server 100 may recommend group driving according to destination information shared with each other at the start or during driving. That is, when users share each other's destination information through a messenger capable of interworking with the recommendation server 100, the recommendation server 100 can recommend platoon driving by calculating a platoon driving gain according to the user's current location and destination. .

In FIG. 2 , the user's recommendation target group may be preferentially searched based on the user's current location 212 and the current locations 222 and 232 of other users.

Since the current locations 222 and 232 of other users must be within a certain distance to meet each other on a common road for group driving, the current location information can be used as a prerequisite.

That is, after searching for other users with the user's current location information 212 , the searched driving route information 220 and 230 of the other user may be compared. The most optimal case overlaps with the user's path 210 , and when there is an overlapping path, group driving may be recommended as the overlapping path.

However, when there is no overlapping path as shown in FIG. 2 , a detour path may be considered.

That is, since the driving path may be determined as the optimal driving path according to the setting for each user, if some paths are different but have similar directions, it may be more advantageous to travel on the common path as a group driving.

Therefore, in order to determine the gain from platooning, if the length of the entire path increased by platooning is negligible, consider the fuel consumption according to circumstances such as deceleration or acceleration of additional speed for merging to determine the swarming gain. can be calculated. The calculated gain is considered as a cluster recommendation condition.

Alternatively, it is also possible to determine the platooning recommendation target in consideration of the fuel consumption rate increased according to the length of the section detoured by single driving for driving on a common route according to the platoon driving and the fuel saving rate according to the platoon driving.

In addition, as more intuitive information, arrival at a predetermined time according to the type of vehicle may be given priority, so it is also possible to determine the benefit of platooning in consideration of the required time to the destination. For example, in the case of transport trucks, delay compensation occurs as the time difference between solo driving and platoon driving increases, or in the case of buses, it may cause changes to the overall operating schedule. It is also possible to determine the target.

In addition, it is also possible to determine the gain of platoon driving by selecting based on the condition that the difference in time required for group recommendation is the difference within a predetermined criterion.

In the case of FIG. 2 , the user needs to deviate from the current driving path at the junction because there is no common path and a target traveling on similar paths 220 and 230 for group driving. It is necessary to re-enter the driving route according to the destination.

That is, an additional detour path is generated for group driving, and it is also possible to recommend another user with the shortest detour path based on the length of the detour paths 226 and 236 at this time.

Alternatively, it is also possible to recommend in consideration of the user's benefit according to the group driving through the characteristics of the routes 224 and 234 to be commonly driven during group driving.

Hereinafter, a method for recommending group driving of the recommendation server 100 according to an embodiment of the present invention will be described in more detail with reference to FIG. 3 .

3 is a flowchart illustrating a group driving recommendation method.

First, the user's driving information is obtained (S30).

The user's driving information includes driving destination, current location, and route information to the destination, and may include additional information such as the current speed of the vehicle and the user's driving time.

The driving information may be directly acquired by the user's terminal, and more detailed information may be acquired through communication with an additional device such as an electronic control unit (ECU) or on-board diagnostics (OBD) of a vehicle.

The driving information may be used in the recommendation server 100 to determine whether group driving is possible and whether a user benefit according to group driving is higher than that of current single driving.

When the recommendation server 100 obtains the driving information, it calculates the user's gain when driving in a group compared to driving alone (S40).

By calculating the user gain, the user may determine whether solo driving or group driving is advantageous, and may recommend group driving.

The recommendation server 100 monitors the user's driving information in real time and continuously checks whether a situation in which group driving is advantageous occurs by comparing it with driving information of vehicles in the surrounding situation.

Accordingly, even if there is no user's conscious request to determine the possibility of platoon driving, when an optimal situation occurs, the recommendation server 100 may suggest to the user and provide the platoon driving service in response thereto.

In addition, when users share each other's destination or departure time within a pre-formed network, for example, within a group chat messenger, the recommendation server 100 suggests an optimal platoon driving route and departure time and provides platoon driving service. It is also possible

In addition, when the user directly requests to determine the possibility of platoon driving, the recommendation server 100 may determine a user benefit according to platoon driving according to a more flexible condition and recommend platoon driving.

Hereinafter, with reference to FIG. 4, the factors determining the user gain will be described.

The user benefit can be judged from two aspects: fuel efficiency and stability according to platoon driving.

First, in relation to fuel efficiency, positive factors that increase user benefit may be reduction of air resistance due to platoon driving and inertia driving due to autonomous driving.

In the case of platoon driving, vehicles of a similar size run at a narrow distance, so following vehicles located at the rear of the platoon receive less air resistance and thus fuel efficiency can be increased.

In addition, when driving in a platoon, the rear vehicles maintain a distance and drive with inter-vehicle communication-based autonomous driving, thereby minimizing the number of accelerations and decelerations, and increasing fuel efficiency according to inertia driving.

In addition, when the user creates a new platoon with the leader vehicle instead of the platoon's follower vehicle, the user may receive an economical reward from the platoon vehicle.

Conversely, as a negative factor, a vehicle traveling alone may change routes for platooning, which may increase fuel consumption.

In addition, in order to join a group, a situation may arise in which acceleration and deceleration are required according to the driving speed of another vehicle or group, and unnecessary fuel consumption may occur compared to driving alone.

Regarding the next stability, first, as positive factors, the improvement of driving convenience and the stability of autonomous driving may be increased.

As described above, in the case of group driving, following vehicles maintain an inter-vehicle distance according to autonomous driving and drive following the leader vehicle, so that the user can minimize the separate driving operation compared to single driving.

Therefore, users who drive for a long time can drive more comfortably through group driving.

In addition, in the case of autonomous driving, vehicles driven in group driving can understand each other's driving conditions through vehicle-to-vehicle communication and control each other accordingly, so it is possible to increase the possibility of detecting dangerous situations compared to single driving, and to reduce the possibility of avoiding accidents. can be raised

Conversely, as a negative factor, in the case of platoon driving, when joining and leaving a platoon, it is necessary to form a platoon at a very close distance or join a driving vehicle, so there is a possibility of an accident.

In addition, in the case of group driving, even if the probability of an overall accident is lowered by predicting a dangerous situation through communication between vehicles and infrastructure, when an accident occurs, a double collision situation may occur depending on the distance between vehicles. The disadvantage is that the damage increases in case of an accident.

Therefore, the recommendation server 100 calculates a user benefit according to the entire group driving in consideration of such a negative factor related to stability.

In terms of fuel efficiency and stability described above, the recommendation server 100 may recommend group driving according to the user's benefit compared to single driving according to platoon driving and calculating the gain according to each factor.

In addition, it is also possible to calculate the user gain according to the characteristics of the path itself according to the group driving.

Referring to FIG. 5 , a user gain may be calculated by using a feature 52 on an actual path on which the user travels in a group.

That is, the characteristics on the path may be extracted based on the common path to be driven for each group rather than the characteristics of the currently driving path in the driving information.

Specifically, it is possible to extract the accident history of the entire or each section of the common route. In other words, if the route to be driven by the gang is a section where accidents occur frequently, the platoon driving may lead to a major accident or further aggravate the congestion of the road, so these characteristics can be considered.

Alternatively, if the point to form a group or to join is a section with a high accident rate among common routes, it is also possible to form or join the group after passing through this section.

Alternatively, the characteristics of the road itself may be used.

For example, a characteristic of a curve section of a section to be grouped may be used.

Specifically, information on the number of curves and curvature of the curve may be used. Relatively, trucks that mainly drive in groups need to be more careful when driving in sharp curves because they have a higher vehicle height and carry heavy cargo compared to general passenger cars.

Accordingly, in the case of group driving, the existence or number of sharp curve sections may be determined based on the curvature of the curve, and this may be reflected in the calculation of the gain according to the group driving.

In addition, the frequency and length of the appearance of tunnels can also be considered, and since tunnels cause major accidents and aggravate congestion, it is possible to recommend a group that can run through these sections when there are many tunnels.

In addition, in the case of slopes, trucks or buses running in groups have a very large weight, so the braking distance is long, and in the case of slope sections, the distance can be longer, so this characteristic can be reflected.

Furthermore, it is also possible to reflect the traffic conditions of the section. The platoon driving can make the traffic situation worse when it is congested, so this can be reflected in the profit calculation.

As described above, in the present embodiment, the recommendation server 100 may calculate and reflect the characteristics of the road within the expected route to be driven in a group in calculating the user gain.

In addition, the group driving may have different benefits depending on the characteristics of the driver of the leader vehicle controlling the driving of the group.

Referring to FIG. 6 , the characteristics of the driver of the leader vehicle may be further determined and reflected in addition to the path and road characteristics of a group to be newly formed or joined by the user.

That is, in the case of a new formation, the characteristics 62 of the driver who becomes the leader vehicle may be reflected, and in the case of participating in the formed group, the characteristics of the current leader vehicle may be reflected.

The characteristics of the specifically used leader vehicle driver may include fuel efficiency, accident history, and driving history information.

Fuel efficiency can be largely collected in two ways. First, it is possible to obtain fuel efficiency information of a vehicle or group driving currently in actual driving.

Alternatively, it is also possible to obtain the accumulated driving history information of the past driver and calculate and use the total fuel efficiency information.

Accordingly, it is possible to determine how well the driver of the leader vehicle of the group to participate in on average is fuel-efficient driving and how the current driving efficiency is compared to the average, and use this to calculate real-time user benefits.

In addition, as the accident history, the safety may be determined using the accident history of the driver of the leader vehicle.

More specifically, it is also possible to determine whether there is an accident point in the route where the group will travel by using the driver's accident history and accident point information.

Through the above process, the accident history can be used as a negative factor in calculating user benefits.

In addition, the driving history may be reflected in the gain calculation by using the current driving time, the entire driving career period, etc. as general driving information.

In this case, when the driver of the leader vehicle spends a lot of driving time in relation to the driving time, it may act as a negative factor for the gain according to the degree of fatigue.

By comparing the driving time of the leader vehicle with the driving time of the user receiving the group recommendation, the leader vehicle having a relatively long driving time may be excluded from the group recommendation.

In addition, when joining a group formed in addition to the leader vehicle, information 64 of a vehicle in front of a location to be actually joined may be further used.

For example, vehicle specification information of the vehicle in front may be used.

With the vehicle specifications, the effect of reducing air resistance and the possibility of an accident during sudden braking can be predicted by the size and braking performance of the vehicle.

In addition, more cargo information is available. Since cargo information changes each time it is driven, the efficiency or risk of platooning may be affected depending on the size or weight of the cargo, it is also possible to calculate user benefits by reflecting this.

The user gain may be finally calculated using the factors described above.

Referring back to FIG. 3 , the recommendation server 100 determines whether to recommend group driving according to the calculated user gain ( S50 ).

For example, when a user gain greater than a reference value set by the user is expected, platoon driving may be recommended.

When the recommendation server 100 recommends a group through a real-time determination process without a request for determining whether the user can drive in a group, when the user's preset reference value or the recommendation server 100 is determined, there is a user benefit compared to single driving You can decide on a recommendation.

When there is a user's request, it is possible to omit the comparison of gains with single driving, and to recommend a cluster in which the highest user benefit is expected among clusters in which group driving is possible.

When the recommendation of group driving is determined through the above process, the recommendation server 100 provides driving guidance information to the user (S60).

In addition, the method further includes the step of querying at least one or more users whether or not to drive in a group according to whether or not it is recommended, and it is also possible to provide the driving guide information when the intention to drive in a group of users participating in the group driving is obtained.

Furthermore, the driving guide information may provide route guidance from the merging location to the destination in consideration of the current location of the group where the group driving is determined or the location of the relative group partner and the user's current location.

The recommendation server 100 considers the merging location together with the road conditions, excludes locations where it is difficult or impossible to join due to expected congestion or road construction, etc., and may determine an appropriate location for the cluster from among possible merging road junctions.

In addition, it is also possible for the recommendation server 100 to determine the merging position by changing it to an appropriate position according to the driving situation of the user. For example, it is also possible for the user to determine the group joining or formation point from the initial starting point as the target location, and as the user approaches the target location, or by recalculating the target location per unit distance.

In this case, the target location may be selected and determined as it approaches the cluster from among the plurality of locations, or it is also possible to determine a wider area rather than a point, but narrow the merging location in such a way that the area decreases as it approaches the cluster. .

In this case, the route guidance may be dynamically provided unlike the conventional turn-by-turn method. In the present embodiment, the user drives along the destination, but the recommendation server 100 may provide route guidance accordingly because the user must travel through the determined merging location for group driving as a stopover.

In addition, since the target location for group driving is an object that moves according to the driving of the group unlike the destination, it is necessary to provide route guidance in consideration of more various factors.

In more detail, the route guidance for group driving may include guidance of the speed of the vehicle for group merging together with the guidance of the traveling direction.

For example, if the driving speed of the group is faster than the driving speed of the user's vehicle and the group is ahead on the route, it is physically impossible to join the group. can

Also, in this embodiment, guidance of vehicle speed may be provided for both sides. That is, roads used for platoon driving are mainly highways, and expressways generally have a speed limit, so it may be dangerous for a vehicle joining the platoon to travel at a speed exceeding the driving speed for merging.

Therefore, it is also possible to generate and provide guidance information to reduce the driving speed of the recommended platoon or partner vehicle and accelerate the user's vehicle speed close to the speed limit according to the distance between the user's vehicle and the platoon.

Hereinafter, a process for group recommendation from the user's side will be described with reference to FIG. 7 .

Referring to FIG. 7 , first, driving information of a user driving a vehicle may be acquired using a user terminal, and the acquired information may be transmitted to the group driving recommendation server 100 ( S72 ).

The user terminal may be a nomadic device such as a smartphone or tablet PC that the user carries and uses. Alternatively, it is also possible to use a terminal device mounted on a vehicle used by the user.

Next, as a result of performing the above-described search process for merging or generating clusters, recommendation information on a cluster having a high user benefit is received from the recommendation server 100 ( S74 ).

That is, the received recommendation group information may be displayed on the display of the user terminal, and additionally, information such as a driving route, leader information, and expected gain expected according to group driving may be provided to the user as detailed information of the recommendation group. .

In the present embodiment, the recommendation of platoon driving may be provided based on the current state of the user even without a separate user request, and thus may be provided as a notification to the user terminal used by the user.

When the user receives the group recommendation information, the user confirms whether to accept the group driving through the user terminal (S76).

If the user confirms and determines the group driving, the user terminal may guide a path for joining the participating group from the current driving position (S78).

In this case, the path for merging may be determined by the user terminal used by the user directly through an internal process, or the recommendation server 100 generates a path between the current location and the merging or new creation point of the recommended group and sends it to the user terminal. It is also possible to do it in a way that provides.

In this embodiment, generation or merging of a group may be performed by the recommendation server 100 because both the origin and destination are dynamically changed compared to general route guidance, and the throughput for calculating the route may be large.

In addition, in the case of a recommendation group, when the user arrives nearby, it is necessary to secure a space for the user to join by widening the interval of the group or by increasing the interval with other rear vehicles. Route guidance may be performed organically.

Accordingly, the route guidance at this time may include guidance on speed deceleration and acceleration. The user is guided through the created path for joining and can perform the joining process.

However, when the user refuses to drive in the group for the recommended group, route guidance according to the single driving may be continuously provided ( S80 ).

Alternatively, a series of processes for group recommendation may be terminated and the user's driving interference according to the recommendation may be minimized.

Hereinafter, the configuration of the recommendation server 100 for performing the above-described cluster recommendation method and an application of the user terminal corresponding thereto will be described.

First, referring to FIG. 8 , in this embodiment, the recommendation server 100 includes a user driving information management unit 110 , a user gain calculation unit 120 , a group driving recommendation unit 130 , and a driving guide information providing unit 140 . can do.

The user driving information management unit 110 receives driving information for users and groups registered in the recommendation server 100 , and manages them in a database.

That is, by using the received driving information, the recommendation server 100 may generate a path for joining or joining a newly created group and a recommended group in real time.

Accordingly, the user gain calculator 120 receives the user's current driving information and determines a recommended group by using the driving information received from each group.

Specifically, it is determined using a path according to the current user's solo driving, and additionally, economic factors and stability factors are analyzed to determine the benefits of joining.

As a result of the determination, if there is a recommendable group, the group driving recommendation unit 130 may provide it to the user to check whether the group is driven.

When receiving the user's confirmation, the driving guide information providing unit 140 creates a route for joining the group. Specifically, the current driving position and the junction point of the participating group are determined, and a corresponding dynamic path is determined.

The determined path may be provided to the user terminal.

In this case, the dynamic route may be determined by changing the origin and destination in real time in response to changes in traffic and driving conditions, and when the route is changed, it is also possible to provide the changed route to the user again.

Referring to FIG. 9 , the application 15 installed in the user terminal corresponds to the recommendation server 100, a driving information transmitter 15a, a group driving recommendation information receiver 15b, a user intention input unit 15c, and a driving guide unit 15d) may be included.

First, the driving information transmitter 15a transmits the current driving information of the user for joining to the recommendation server 100 .

Next, the group driving recommendation information receiving unit 15b receives the determined participation target group information from the recommendation server 100 .

The group driving recommendation information receiving unit 15b may provide the received information on the participating target group to the display device of the user terminal.

The user intention input unit 15c may directly receive the user's intention to participate together with information on the participation target group. Specifically, a user's intention may be input using a user interface of the display device.

When the user determines group driving and inputs his intention, the driving guide 15d receives the driving route from the recommendation server 100 and provides route guidance information to the user.

That is, the group recommendation according to the present embodiment is performed by the organic operation of the recommendation server and the user application installed in the vehicle, and through this, the user can form a more advantageous group and drive or safely join.

In addition, in the present embodiment, the recommendation server 100 and the application 15 installed in the user terminal may recommend group driving in conjunction with the messenger 25 installed in the user terminal.

Referring to FIG. 10 , the application 15 may provide a platoon driving recommendation service by interworking with a messenger 25 that can communicate with each other among users.

When users share destination information with each other in the group chat room of the general messenger 25 of the form shown in FIG. 10 , the driving information transmitter 15a of the above-described application 15 includes the users' current location and destination information. current driving information may be transmitted to the recommendation server 100 .

For example, user A 10a may share that the destination is Busan and user C 10c has the destination Daegu through the group messenger 25 . In addition, user D (10d) can share that Ulsan is the destination on the messenger.

The destination information shared on the messenger may be transmitted to the recommendation server 100 through the driving information transmitter 15a, and the recommendation server 100 calculates the user benefit according to the platoon driving and recommends platoon driving as described above. can give

The platoon driving recommendation information receiving unit 15b may receive the platoon driving recommendation information generated by the recommendation server 100 , and the recommended information may be provided to each user as a message on the group messenger 25 .

For example, user A 10a, the farthest destination, may be provided as a message 10a-1 by the leader as the leader of the group, and through this, other users 10c and 10d may respond to the intention to drive the group. .

In detail, information for the user to respond may be provided to the additional interface 25a of the group messenger 25 .

The interface 25a may include route information 25a-1 to be driven in a group, an expected fuel saving rate 25a-2, and an input interface 25a-3 for accepting/rejecting group driving through the interface 25a. .

The user intention input unit 15c receives the user's intention to group driving input through the input interface 25a - 3 .
