1. A method for controlling, by a first device, platooning of a first platooning group in a wireless communication system, the method comprising:
receiving first information on a second platooning group controlled by a second device from the second device;
transmitting a merge request message for merging with the second platooning group based on partial or all of a match between a second path of the second platooning group included in the first information and a first path of the first platooning group;
transmitting, to devices included in the first platooning group, platooning information for a merged platooning group in which the first platooning group and the second platooning group are merged ; and
receiving a response message including a bitmap including a number of bits corresponding to the number of devices belonging to the second platooning group from the second device; and
determining a target device to follow among the devices belonging to the second platooning group based on a position of a specific bit having a value of 1 in the bitmap,
wherein, based on the first path partially matching the second path, the platooning information further includes first platooning information for the first platooning group as sub-platooning information.
