Referring to FIG. 5 , in the vehicle driving-related composite control method according to an embodiment of the present invention, the driving composite control device 300 may collect vehicle information in step 501 . In this operation, the driving composite control device 300 may collect vehicle information about a plurality of vehicles belonging to the plurality of RSUs 51 and 52 . Alternatively, the driving composite control device 300 may provide vehicle information of at least one vehicle located at the edge of the communication coverage of the plurality of RSUs 51 and 52 (or an outer area outside a predetermined distance from the center of the RSU). can be collected. Alternatively, there is a possibility that the driving complex control unit 300 moves from a management area (or communication coverage) of a specific RSU (eg, the first RSU 51) to a management area of another RSU (eg, the second RSU 52). High vehicle information can be collected. In this regard, the driving complex control device 300 includes location information of each of the RSUs 51 and 52, location information of the communication coverage (or management area) of each RSU 51 and 52 and the edge area of the communication coverage, Information on the current location, movement direction, and movement speed of vehicles may be collected.

In step 503, the driving composite control apparatus 300 may check whether a vehicle to be changed with RSU exists. For example, the driving composite control device 300 may check whether there are vehicles moving in a direction away from the center of each RSU while being located at the edge of each RSU. When the vehicle to be changed RSU does not exist, in step 505, the driving composite control apparatus 300 may perform vehicle flow control. For example, the driving composite control apparatus 300 determines the number of vehicles belonging to each of the RSUs 51 and 52, the destination of the vehicles, the moving direction of the vehicles, and the moving speed of the vehicles, based on the RSUs 51 and 51 of the vehicles. 52) can determine the flow of movement between The driving composite control device 300 generates a message for adjusting the road and moving speed of the vehicles to be used so that the vehicles do not belong to a specific RSU more than a certain density in consideration of the destinations and the desired arrival time of the vehicles, and generates a message for each RSU. It can be delivered to fields (51, 52).

If there is a vehicle to be changed RSU, the complex driving control apparatus 300 may detect a collision or a risk of collision in step 507 . In this regard, the driving composite control device 300 checks the moving direction and speed of the first vehicle moving from the first RSU 51 to the second RSU 52 and the lane in use, and determines the moving direction and the current lane in use. It may be determined whether a second vehicle exists in an edge area of the management area of another RSU connected to the lane. The driving composite control apparatus 300 detects that there is a risk of collision when the moving speed of the second vehicle is lower than the moving speed of the first vehicle and the distance between the first vehicle and the second vehicle is within a specified distance. can As another example, when an intersection exists at the edge of the management area of the first RSU 51 and the edge of the management area of the second RSU 52, the driving complex control unit 300 determines the moving speed and direction of vehicles to use the intersection. Taking this into account, it is possible to determine whether there is a vehicle that will cause a collision risk.

If there is a vehicle with a risk of collision, the driving complex control unit 300 may remove the risk of collision by transmitting a message to adjust (eg, decelerate) the moving speed of the vehicle to enter the new RSU to the corresponding RSU and vehicle. there is. When there are vehicles with a risk of collision, the driving composite control device 300 may generate a message adjusting the speed of vehicles to enter the intersection in consideration of the current state of the traffic lights installed at the intersection, and transmit the message to each RSU. there is. Here, the driving complex control apparatus 300 may deliver a message related to vehicle speed adjustment in consideration of the belonging state of corresponding vehicles in order to manage the risk of collision or the risk of collision. For example, when there is a vehicle moving from the first RSU 51 to the second RSU 52, and receiving new entry vehicle information from the second RSU 52, the driving composite control device 300 performs a new entry vehicle. A message for adjusting the speed of the entering vehicle may be transmitted to the second RSU 52 . In this operation, the driving complex control device 300 may transmit a message requesting management end to the vehicle entering the second RSU 52 to the first RSU 51 .

As another example, when there is a risk of collision between the first vehicle moving from the first RSU 51 to the second RSU 52 and the second vehicle of the second RSU 52, A request may be made to the first RSU 51 to overtake the first vehicle. When the first vehicle is changed to belong to the second RSU 52 while performing a lane change for overtaking the first vehicle, the driving composite control device 300 informs that the first vehicle is in the process of overtaking the second vehicle. By transmitting the message, overtaking of the first vehicle can be controlled by the second RSU 52 to continue. In this operation, the complex driving control device 300 may transmit a message requesting termination of management of the first vehicle to the first RSU 51 .

The above-described present invention performs control of a vehicle equipped with only a GPS module and network communication equipment through an RSU, defines functions to be performed in the RSU through system structure of the RSU, and operates a driving complex control device 300 (or control center) For vehicles moving within a plurality of RSUs, by defining the vehicle path control function through the RSU and defining the function to be performed in the driving complex control unit 300 through the structure definition of the driving complex control unit 300 Safe control can be supported.
