Abstract
A vehicle control system includes a vehicle control apparatus, a first portable device, and a second portable device. The first portable device transmits a first signal to the vehicle control apparatus based on the fact that a first operation by a user is performed on the second portable device. When the vehicle control apparatus receives the first signal from the first portable device, the vehicle control apparatus intermittently transmits a second signal to the first portable device. The first portable device measures a signal strength of the second signal received from the vehicle control apparatus, based on the fact that a second operation by the user is performed on the second portable device after the first operation. The vehicle control apparatus or the first portable device sets, as a distance threshold, a distance between the first portable device and the vehicle calculated from the measured signal strength.
