Patent number: 9251426Abstract: A three-dimensional object detection device is provided with an image capturing device, a three-dimensional object detection unit, a rainfall state detection unit, a three-dimensional object assessment unit and a controller. The image capturing device captures an area rearward of a vehicle. The three-dimensional object detection unit detects a three-dimensional object rearward of the vehicle and calculating a traveling speed of the three-dimensional object, based on images obtained by the image capturing device. The rainfall state detection unit detects a state of rainfall including cases of rainfall or formation of a water film on a road surface due to rainfall. The three-dimensional object assessment unit accesses the three-dimensional object to be another vehicle when the traveling speed of the detected three-dimensional object lies within a preset setting range.

Patent number: 9092676Abstract: A solid object detection device detects solid objects in the periphery of a vehicle. A camera captures images including detection regions set in adjacent traffic lanes to the rear of the vehicle. A solid object assessment unit assesses whether or not a solid object is present in the detection regions. A lateral position detection unit detects a distance between the vehicle position and a dividing line that divides traffic lanes. A region setting unit enlarges the detection region on the side of the dividing line by a greater amount correspondingly with respect to an increase in the distance to the dividing line. A traffic lane change detection unit detects a traffic lane change made by the vehicle. Upon detecting a traffic lane change by the vehicle, a smaller enlarged amount is used when enlarging the size of the predetermined region outward in the vehicle-width direction.Type: GrantFiled: July 27, 2012Date of Patent: July 28, 2015Assignee: Nissan Motor Co., Ltd.Inventors: Yasuhisa Hayakawa, Chikao Tsuchiya, Osamu Fukata, Yukinori Nishida, Daisuke Oiki

Patent number: 8326481Abstract: A vehicle driving assist system calculates a risk potential indicative of a degree of convergence between a host vehicle and a preceding obstacle. Then, the system performs a driver notification operation that produces a driver notification stimulus based on the risk potential such as decreasing the driving force exerted against the vehicle as the risk potential increases and increasing an actuation reaction force exerted on the accelerator pedal during its operation as the risk potential increases. If a failure is detected in a reaction force generating device serving to add a reaction force to the accelerator pedal in accordance with the risk potential, then the system corrects an engine torque characteristic such that the engine torque does not increase even if the accelerator pedal is depressed to suppress an odd feeling in the vehicle performance by the driver when a failure occurs in the reaction force generating device.Type: GrantFiled: January 13, 2012Date of Patent: December 4, 2012Assignee: Nissan Motor Co., Ltd.Inventors: Takeshi Kimura, Yosuke Kobayashi, Yukinori Nishida
