Abstract
A vehicle control system includes a first transmitter that transmits a predetermined first signal over a predetermined area, a first receiver and a second receiver that receive second and third signals, a detector that detects the field intensities of the received signals, a second transmitter that transmits a signal through an RF-band radio wave, and an electronic control unit that operates an in-vehicle device based on the third signal received by the first receiver and restrains or prohibits the in-vehicle device from being operated based on the third signal when the field intensity of the third signal is lower than the field intensity of the second signal by a value greater than a predetermined standard.
