Publication number: 20120078553Abstract: A battery charge amount increase facility information provision device provides information relating to a battery charge amount increase facility to a vehicle installed with a battery (60) that is charged using an external power supply. The device includes a current position sensor (51) which detects a current position of the vehicle, a charge amount sensor (52) which detects a battery charge amount (SOC), a database (20) which registers the formation relating to the battery charge amount increase facility, and a controller (10). The controller (10) registers the current position of the vehicle in the database (20) as a location of a battery charge amount increase facility when the SOC has increased under a predetermined condition (S113). As a result, an amount of information relating to the locations of usable battery charge amount increase facilities is increased.Type: ApplicationFiled: June 4, 2010Publication date: March 29, 2012Inventors: Koichi Kuroda, Yasunori Maruyama, Kazuhito Katou, Ken Oizumi

Patent number: 7782374Abstract: An image processor is disclosed for a vehicle having a plurality of cameras and a monitor that displays a panoramic image derived from multiple images generated by the plurality of cameras. The processor includes input buffers for storing camera image data captured through respective camera modules and output buffer for storing a panoramic image. The camera image data for generating the panoramic image are retrieved from input buffers. The camera image data are stored in an output buffer using an reconfigured address conversion table. The reconfigured address conversion table is an address conversion table which is obtained by reconfiguring an address conversion table when camera modules are assumed to be free of vehicle installation errors. The reconfiguration is performed on the basis of parameters which are used to correct vehicle installation errors of camera modules.Type: GrantFiled: March 2, 2006Date of Patent: August 24, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Masayasu Suzuki, Ken Oizumi, Takeshi Akatsuka
