Publication number: 20180144201Abstract: A scene understanding device obtains map data where one, two or more obstacle detection frames, shaped corresponding to a road structure, for detecting an obstacle are set in advance for a specific spot on a road where a vehicle would otherwise bump into a vehicle or a pedestrian. The scene understanding device determines whether there exists an obstacle in the obstacle detection frames set for the specific spot on a scheduled traveling route of a host vehicle, and calculates the degree of risk at the specific spot based on a result of determining whether there exists an obstacle therein.Type: ApplicationFiled: April 23, 2015Publication date: May 24, 2018Inventors: Masanori Yoshihira, Seigo Watanabe, Norimasa Kishi

Publication number: 20170267286Abstract: A method of assisting a driver of a vehicle includes obtaining a feature of a road to be traveled by the vehicle with a sensor and/or a GPS system. A parameter is selected to assist a driver of the vehicle in driving a segment of the road based on the feature of the road. The parameter includes information on the location of a boundary along the road and a preferred trajectory to be driven along the road. A controller determines whether a current trajectory of the vehicle while travelling the road is deviating from the preferred trajectory of the vehicle along the road. A feedback operation is provided to assist the driver in guiding the vehicle nearer to the preferred trajectory based on the selected parameter.Type: ApplicationFiled: September 26, 2014Publication date: September 21, 2017Applicant: NISSAN MOTOR CO., LTD.Inventors: Yoshiro TAKAMATSU, Yuji TAKADA, Yoshinori KUSAYANAGI, Norimasa KISHI

Patent number: 9649980Abstract: Captured images obtained beforehand by imaging ranges corresponding to peripheries of a vehicle, or processed images generated to correspond to the captured images are stored to be associated with stored road information of a preset area. A superimposed area having a clarity lower than a preset clarity threshold is set in a captured image of a periphery of the vehicle. A superimposition image is extracted among the stored images, the superimposition image being an image of a range corresponding to the captured image. A superimposed image is generated by superimposing an image in an area in the extracted superimposition image corresponding to the superimposed area on the captured mage. A video generated from the superimposed image is displayed at a position visible from a driver.Type: GrantFiled: April 5, 2013Date of Patent: May 16, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Seigo Watanabe, Norimasa Kishi, Takura Yanagi, Yoshiro Takamatsu

Publication number: 20050075144Abstract: A service terminal 3 accesses a vehicle 2 by using a service provider ID and a service ID. When the access to the vehicle 2 is authenticated, vehicle information that is necessary to provide a service of which utilization is applied for is read out. The read information is encrypted using an encryption key, and the encrypted information is transmitted to the service terminal 3. With this arrangement, the access to an in-vehicle network can be managed for each service provider while maintaining security. Therefore, vehicle equipment exclusive for each service needs not be installed. Consequently, workload and cost of both the service provider and a user who receives the service can be reduced.Type: ApplicationFiled: October 1, 2004Publication date: April 7, 2005Inventors: Toshiro Muramatsu, Norimasa Kishi

Publication number: 20040169653Abstract: In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. In this case, an input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined on the basis of the coordinates of a current position and a destination and the position of the view point so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, and the position of the view point and the projection plane are determined on the basis of the coordinates of the two points and the scale so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale.Type: ApplicationFiled: March 9, 2004Publication date: September 2, 2004Inventors: Yoshinori Endo, Toshio Fujiwara, Hiroyuki Satake, Hiroshi Shojima, Norimasa Kishi, Masaki Watanabe, Motoki Hirano

Patent number: 6766249Abstract: An apparatus provides information for a driver and passengers in a vehicle. If it is estimated that driving load is high, the apparatus stops outputting information. If it is estimated that driving load has been changed from high to low, the apparatus reads information from a storage unit and outputs the read information. If it is estimated that driving load is high, the apparatus stops outputting information so that the driver and passengers may miss no information, and if it is estimated that driving load is low, the apparatus provides information for the driver and passengers so that they may surely catch the information.Type: GrantFiled: September 12, 2001Date of Patent: July 20, 2004Assignee: Nissan Motor Co., Ltd.Inventors: Satoshi Okamoto, Norimasa Kishi, Hiroshi Saito, Koji Sato

Patent number: 6718187Abstract: With a mobile telephone (10) set into a telephone holder (11), if a telephone call is received, rather than sounding an audible ringing, a head-up display (60) notifies the driver by a display (67) made in a peripheral vision region (64) outside of a central vision region (63) of the driver. The driver can respond to the incoming call only in the case in which the driving burden on the driver is small enough that, even without the aid of an audible ringing, the driver can notice the received-call display in only the peripheral vision region.Type: GrantFiled: August 9, 2000Date of Patent: April 6, 2004Assignee: Nissan Motor Co., Ltd.Inventors: Toru Takagi, Toshirou Muramatsu, Norimasa Kishi
