Patent number: 9069078Abstract: A radar device (10) comprising a transmission antenna (14) for transmitting electromagnetic waves; a reception antenna (15) for receiving waves; and a detector unit (34) which detects, based on the reflected waves, the positions of a preceding vehicle and a preceding object, judges the preceding object to be the same as the preceding vehicle if the position of the preceding object is in a predetermined preceding vehicle judging range with the position of the preceding vehicle as a reference, detects the positions of an oncoming vehicle and an oncoming object and judges the oncoming object to be the same as the oncoming vehicle if the position of the oncoming object is in a predetermined oncoming vehicle judging range with the position of the oncoming vehicle as a reference; wherein the oncoming vehicle judging range is set to be narrower than the preceding vehicle judging range.Type: GrantFiled: February 3, 2012Date of Patent: June 30, 2015Assignee: FUJITSU TEN LIMITEDInventors: Hiroyuki Ishimori, Hideki Kajioka, Shinichi Shibata

Patent number: 8674873Abstract: A signal processing apparatus performs an object detection process of detecting object data with respect to peak signals which indicate a difference in frequency between a transmitted signal of which the frequency is changed in a predetermined period and a received signal which is obtained by receiving a reflected wave that corresponds to a transmitted wave which is based on the transmitted signal and is reflected from an object, by deriving the peak signals in a first period where the frequency of the transmitted signal ascends and in a second period where the frequency of the transmitted signal descends and by pairing the peak signals in the first period and the second period. A continuity determination section determines a continuity between the object data and past object data detected prior to the object data.Type: GrantFiled: September 15, 2010Date of Patent: March 18, 2014Assignee: Fujitsu Ten LimitedInventors: Shinichi Shibata, Hideki Kajioka

Patent number: 8633849Abstract: A vehicle mounted radar device operable to scan a transmission wave to detect a detection point representing a position of an object disposed around the vehicle on the basis of a reflected wave of the transmission wave from the object. The radar device includes a reading unit, a continuity determination unit, a setting unit, anti an object determination unit that are configured to prevent the radar device from erroneously determining different pieces of object information as a single object.Type: GrantFiled: February 15, 2011Date of Patent: January 21, 2014Assignee: Fujitsu Ten LimitedInventors: Shinichi Shibata, Hideki Kajioka, Hiroyuki Ishimori

Patent number: 7893864Abstract: A radar apparatus is provided. An antenna is configured to transmit a frequency-modulated transmission wave toward an object and receive a reception wave from the object. A mixer is configured to mix the transmission wave with the reception wave to generate a beat signal having a first beat interval and a second beat interval. A detecting section is configured to detect a plurality of first peak signals contained in the first beat interval of the beat signal and a plurality of second peak signals contained in the second beat interval. A grouping section is configured to group the second peak signals. A searching section is configured to search a part of the first peak signals corresponding to the grouped second peak signals. A separating section is configured to separate the part of the first peak signals from the other part of the first peak signals.Type: GrantFiled: August 7, 2009Date of Patent: February 22, 2011Assignee: Fujitsu Ten LimitedInventors: Shinichi Shibata, Hideki Kajioka

Patent number: 6954174Abstract: A radar apparatus for a vehicle includes a casing, a correction member, and a selection indication. The casing includes a functional portion, which performs searching, and a reference surface. The correction member includes a plurality of correction surfaces. The selection indication indicates which one of the correction surfaces and the reference surface an attachment-direction adjustor is to be placed on during an attachment operation of the radar apparatus to the vehicle.Type: GrantFiled: May 21, 2004Date of Patent: October 11, 2005Assignee: Fujitsu Ten LimitedInventors: Osamu Isaji, Hideki Kajioka, Norihiko Hatanaka

Patent number: 4987296Abstract: A rain sensor operates such that when a raindrop cuts off a direct light beam from a transmitter to a detector, the output level of the detector is lowered. A convex member is disposed to prevent a portion of the light emitted from the transmitter from reflecting and then reaching the detector. Thus, detecting error due to such reflected light is reduced.Type: GrantFiled: August 10, 1989Date of Patent: January 22, 1991Assignee: Fujitsu Ten LimitedInventors: Hideki Kajioka, Yasuhiro Fujita, Keiji Fujimura
