Patent number: 9381811Abstract: A vehicle driving assist system has a controller configured to urge a driver to slow down (decelerate) in locations where visibility is poor. The controller detects a traveling condition of a host vehicle, e.g., when the host vehicle is approaching a designated area, such as a school zone, and then selectively executes an imaginary speed limiting road protrusion control that generates an imaginary speed limiting road protrusion by artificially reproducing a vehicle behavior that simulates the host vehicle crosses an actual speed limiting road protrusion arranged on a road surface, based on the traveling condition of the host vehicle.Type: GrantFiled: August 8, 2006Date of Patent: July 5, 2016Assignee: Nissan Motor Co., Ltd.Inventors: Takayuki Kondoh, Tomohiro Yamamura, Nobuyuki Kuge, Kenji Komori

Patent number: 7809506Abstract: A driving intention estimation, driver assistance and vehicle with the driver assistance for providing a stable estimation of a driver's driving intention even if detection of a relationship between an own vehicle and lane markers is lost. A plurality of imaginary drivers of a first type and a second type, each being given a respective driving intention, are provided. When detection of lane markers is reliably kept, a driving intention by a real driver is estimated based on a comparison between an operation of the real driver to operations of the imaginary drivers of the first type that are calculated based on the relative positional relationship of the own vehicle to the detected lane marker. When the detection of lane markers is lost, operations of the plurality of imaginary drivers are calculated based on the relative positional relationship of the own vehicle to a preceding vehicle.Type: GrantFiled: November 23, 2005Date of Patent: October 5, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Nobuyuki Kuge, Takeshi Kimura
