Abstract
A vehicle control device includes a plurality of LF transmitters transmitting response request signals that reach an area around a vehicle and an interior of a vehicle chamber, and a UHF receiver receiving a signal transmitted from a portable machine. The portable machine includes an LF receiver receiving the response request signal and a UHF transmitter transmitting a response signal. The LF receiver in the portable machine has a reception region in which the response request signals transmitted from at least two of the LF transmitters are receivable when the portable machine approaches the vehicle. Door locking/unlocking is permitted if the LF receiver in the portable machine receives the response request signals transmitted from at least two of the LF transmitters within a predetermined time period. In contrast, door locking/unlocking is inhibited if the LF receiver receives the response request signal transmitted from one of the LF transmitters.
