Title:
VEHICLE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/017877
Kind Code:
A1
Abstract:
Provided is a vehicle control system which suppresses damage due to a relay attack. In one embodiment of the present invention, in an away-from-home mode in which a user leaves home (5), an in-vehicle device transmits a radio wave B of a Bluetooth (registered trademark) communication system, transmits a radio wave A of an LF band if there is a response from a key (4) to the radio wave B, and does not transmit the radio wave A if there is no response. The in-vehicle device enables unlocking of a door and engine startup of a vehicle (2) if there is a response from the key (4) to the radio wave A. In the away-from-home mode, the key (4) responds to the radio wave A if the radio wave B from the in-vehicle device was received, and restricts the response to the radio wave A if the radio wave B could not be received. In addition, if the user returns to home (5), the in-vehicle device and the key (4), on the basis of communication with a home device provided to the home (5), switch to an at-home mode in which operations are restricted.
