Publication number: 20230115532Abstract: A vehicle 2 is provided with an authentication system 4 which enables operating a user's terminal 3 as a key to the vehicle 2. The authentication system 4 performs authentication by means of near-field communication between the terminal 3 and a wireless authentication device 22 and operates a device 20. A determination unit 33 confirms the use state of the terminal 3 at the time when near-field communication was performed, and determines whether or not the confirmed use state of the terminal 3 satisfies a condition for stopping or restricting the key function. If the determination unit 33 has determined that the confirmed use state of the terminal 3 satisfies the condition for stopping or restricting the key function, then a processing unit 36 performs processing for stopping or restricting the key function.Type: ApplicationFiled: March 24, 2021Publication date: April 13, 2023Inventors: Masanori KOSUGI, Hideki KAWAI, Yohei NIWA, Shingo MOCHIZUKI, Haruki YAMAMURA, Akira HASEGAWA
