Patent number: 10178094Abstract: An information collection method includes determining whether or not a vehicle satisfies predetermined conditions when a target device receives a test mode start request from an collection device, and when it is determined that the vehicle satisfies the predetermined conditions, starting the test mode. In the test mode, update of a predetermined counter is stopped. The collection device generates a first MAC based on the count value received from the target device and transmits an attack information acquisition request with the first MAC to the target device. If the attack information acquisition request with the first MAC is received from the collection device, the target device generates a second MAC based on the stopped count value, determines that the host device is normal in a case where the first MAC and the second MAC coincide with each other, and transmits the attack information to the collection device.Type: GrantFiled: December 15, 2016Date of Patent: January 8, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Satoh, Serina Egawa, Yoshihiko Katoh

Patent number: 8654797Abstract: To provide a data relay device which prevents a significant delay even when pieces of data are transmitted/received in protocols that are different from each other. Transmission timings at which pieces of data are transmitted/received in a network using an event trigger type communication protocol are estimated. Stay periods which occur when pieces of data are relayed and transmitted at predetermined transmission timings in a network using a time trigger type communication protocol are calculated while changing a reference time for the time trigger type communication protocol. Then, synchronization processing is performed in the network using the time trigger type communication protocol such that communication is performed using a reference time having a small stay period that has been calculated.Type: GrantFiled: April 8, 2009Date of Patent: February 18, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroya Ando, Osamu Hirashima, Yusuke Satoh, Katsutomo Sasakura
