[ 18. An apparatus in a first vehicle to correct position information of a surrounding vehicle, the apparatus comprising:
a front vehicle location unit comprising one or more processors configured to:
obtain identifier information of a second vehicle that is travelling in front of the first vehicle while the first vehicle is travelling on a curved road,
measure a distance from the first vehicle to the second vehicle, and
determine a relative position of the second vehicle with respect to a current position of the first vehicle using the measured distance from the first vehicle to the second vehicle;
a surrounding vehicle information receiver configured to receive identifier information and position information of one or more surrounding vehicles; and
a position information correcting unit comprising one or more processors configured to:
identify a surrounding vehicle comprising identifier information corresponding to the identifier information of the front travelling vehicle among the received identifier information of the one or more surrounding vehicles as being a matching surrounding vehicle corresponding to the front travelling vehicle,
compare the determined relative position of the second vehicle with received position information of the matching surrounding vehicle among the received position information of the one or more surrounding vehicles,
correct the received position information of the matching surrounding vehicle according to a result of the comparing, and
transmit the corrected position information of the matching surrounding vehicle to a driving assist system to prevent a collision between the first vehicle and the second vehicle,
wherein the collision between the first vehicle and the second vehicle is prevented by a forward collision warning system. ]
