Patent number: 10320772Abstract: The present invention is directed to solve a problem that time is required for a process related to verification of a public key certificate of a message sender. An in-vehicle device mounted on a vehicle has a memory for holding information of a device which failed in verification of a public key certificate. At the time of performing communication between vehicles or between a vehicle and a roadside device, a check is made to see whether or not information of a device included in a message transmitted matches information of a device which failed and held in the memory. When the information matches, verification of a public key certificate is not performed.Type: GrantFiled: March 31, 2017Date of Patent: June 11, 2019Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Eriko Ando, Takashi Kawauchi, Toru Owada

Publication number: 20160078761Abstract: If identification information is updated periodically, there is such a problem that when another vehicle is receiving driving support based on transmitted identification information of an own vehicle, if the identification information of the own vehicle is updated, the operation of driving support using the identification information becomes unstable because another vehicle can no longer identify the own vehicle. A mobile terminal mounted on a vehicle determines whether or not transmission control of identification information is necessary after determining the possibility of identification information misuse, determining the effect by controlling transmission of identification information, and determining the magnitude of adverse influence on the safe driving support service.Type: ApplicationFiled: November 23, 2015Publication date: March 17, 2016Inventors: Eriko Ando, Takashi Kawauchi, Toru Owada
