This vehicle communication system comprises: an in-vehicle device (1) that is installed in a vehicle and includes a vehicle-side communication unit (11, 12); a portable device (2) that is carried by a user and includes a first portable device communication unit (21, 22) for wirelessly communicating with the vehicle-side communication unit; and a portable terminal (3) that is carried by the user and includes a portable terminal communication unit (31) for wirelessly communicating with a second portable device communication unit (26) contained in the portable device. The portable terminal comprises: a parking location acquisition unit (35) that acquires the parking location of the vehicle when the user exits the vehicle; a location detection unit (32) that detects the location of the portable terminal; and a calculation unit (30) that calculates the distance between the parking location and the portable terminal on the basis of the parking location and the location of the portable terminal. When the calculated distance is within a predetermined range, the portable terminal communication unit transmits distance information, containing the distance, to the second portable device communication unit. When the second portable device communication unit receives the distance information, the first portable device communication unit (22) transmits approach information, containing the distance information, to the vehicle-side communication unit (12).
