Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2017/208481
Kind Code:
This vehicle authentication system comprises: an on-vehicle device provided with a transmission processing unit that causes transmission of a request signal; and a mobile device provided with a reply unit (23) that transmits a response signal in response to the request signal. The on-vehicle device is further provided with a sound output processing unit that, when the transmission processing unit causes transmission of the request signal, also causes a sound output device, which outputs a predetermined sound in an audible range, to output the predetermined sound. The mobile device is further provided with: a sound collecting unit (24); and a mobile-side sound verifying unit (214) that verifies, on the basis of a predetermined normal sound, a sound collected by the sound collecting unit. In a case where the mobile-side sound verifying unit does not succeed in verification, even when receiving the request signal, the reply unit does not transmit a response signal including an identification code.
