When intermittently transmitting the first response request signal at predetermined intervals via the vehicle-mounted transmitter, the controller determines whether condition set in advance is established. When the condition is established, the controller transmits a second response request signal different from the first response request signal. When the vehicle-mounted receiver receives a response signal which is transmitted from the portable device as a response to the second response request signal, the controller continues to transmit the second response request signal via the vehicle-mounted transmitter.

Vehicle control apparatus

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.

Vehicle control system

A vehicle control system includes a vehicle control apparatus mounted on a vehicle for controlling the vehicle, an electronic key carried by a user for performing communication with the vehicle control apparatus, and a portable device carried by the user for performing communication with the electronic key.
