Patent number: 10843695Abstract: In an apparatus, a first obtainer obtains a first travelling-condition parameter of a target vehicle. The first travelling-condition parameter shows one or more conditions under which the target vehicle is travelling on the road. A second obtainer obtains a second travelling-condition parameter of a preceding vehicle travelling on the road immediately ahead of the target vehicle. The second travelling-condition parameter shows one or more conditions under which the preceding vehicle is travelling on the road. A deviation calculator calculates a deviation between the first and second travelling-condition parameters. A behavior deter miner deter mines a recommended behavior of the target vehicle in response to the calculated deviation. A controller controls a device, which is associated with a behavior of the target vehicle, according to the recommended behavior.Type: GrantFiled: September 20, 2018Date of Patent: November 24, 2020Assignee: DENSO CORPORATIONInventors: Hiroaki Niino, Masao Oooka, Shotaro Fukuda, Takahiro Narita

Patent number: 10829124Abstract: An evacuation driving assistance apparatus capable of evacuation driving toward an appropriate evacuation location is provided. In the evacuation driving assistance apparatus, a driver determination unit determines whether or not a driver of an own vehicle is in a normal-driving enabled state. If it is determined by the driver determination unit that the driver of the own vehicle is in a normal-driving disabled state, a notification unit provides a notification of location information of the own vehicle to a center. The center is capable of determining an evacuation location based on the location information of the own vehicle, and transmitting the evacuation location. A reception unit receives the evacuation location transmitted by the center. An evacuation driving execution unit executes evacuation driving toward the evacuation location received by the reception unit.Type: GrantFiled: August 10, 2016Date of Patent: November 10, 2020Assignee: DENSO CORPORATIONInventors: Takahiro Narita, Masao Oooka, Masuhiro Kondo
