Patent number: 9514648Abstract: An alerting apparatus issues an alert regarding a moving obstacle to a driver of a host vehicle when the host vehicle enters an intersection of a crossroad that is connected to a traveling road on which the host vehicle is traveling, and the traveling road, in a left-hand traffic jurisdiction. This alerting apparatus includes an ECU. The ECU is configured to issue the alert regarding the moving obstacle when it is determined that a path of the moving obstacle intersects with an intersect determination range, and set the intersect determination range to be shorter in length in a front-rear direction of the host vehicle when the traveling direction of the host vehicle is a left turn than when the traveling direction of the host vehicle is a right turn.Type: GrantFiled: November 12, 2015Date of Patent: December 6, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shinya Kawamata, Kiyoto Hanita

Patent number: 9064419Abstract: A driver condition determination device determines whether a driver of a host vehicle has degraded consciousness. A main component for distribution of an accelerating operation condition with respect to proximity when tailgating a preceding vehicle is analyzed (S16), all data is origin-shifted (S18), and the accelerating operation condition of the driver when the driver has consciousness is created as a normal traveling model (S20). The likelihood of the accelerating operation condition, a likelihood average, a likelihood variance, and a likelihood threshold value are calculated (S22 to S26), and it is determined whether the likelihood of a current driving operation is lower than the likelihood threshold value (S28). When the likelihood is lower than the likelihood threshold value, the driver is determined as being in degraded consciousness.Type: GrantFiled: April 23, 2012Date of Patent: June 23, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hirofumi Aoki, Kiyoto Hanita
