Publication number: 20080086268Abstract: A method and apparatus for determining the position of an object relative to a moving vehicle. While the vehicle is moving in a first direction, successive sensor pulses are transmitted from a vehicle sensor and toward the object. The echo or reflection from the sensor pulse is then received while a processor determines the transit time between the transmission of each pulse and the receipt of its echo. An angle factor is then calculated which represents the difference between the elapsed time of two sequential sensor pulses and the distance traveled by the vehicle between those two pulses. Whenever the absolute value of the angle factor exceeds a preset threshold, an angle is selected from a predefined lookup table contained in memory. Conversely, when the absolute value of the factor is less than the preset threshold, the angle is calculated as a function of the factor.Type: ApplicationFiled: October 6, 2006Publication date: April 10, 2008Applicant: Toyota Engineering & Manufacturing North America, Inc.Inventor: Masato Okuda

The communication terminal includes: an image shooting part that shoots an image around the communication terminal; a position acquisition part that obtains a position at which the image is shot; a recording part that associates and records the shot image and the position; and a receiving part that receives the request signal; and an image transmission part that transmits an image.Type: ApplicationFiled: April 27, 2007Publication date: December 13, 2007Inventors: Mitsuhiro Kitani, Hidenori Sakaniwa

Publication number: 20070285305Abstract: An obstacle detection system determines a probability distribution of existence of an obstacle object corresponding to a distance in an irradiation direction of a transmission wave based on detected strength data per scanning-angle supplied from a radar device. A peak-value of the strength data becomes a maximum probability of existence of the obstacle. The probability distribution has a range gradually decreasing before and after the peak-value. Even if the position indicated by the maximum probability of existence of the obstacle object is different from an actual distance to the obstacle object, it hardly occurs that the probability of existence at an actual position of the obstacle object becomes zero. This eliminates occurrence of separation/association errors. Primary and secondary existence probability relationships made based on the probability distribution are combined. Using the combined one further decreases the error detection.Type: ApplicationFiled: June 7, 2007Publication date: December 13, 2007Applicant: DENSO CorporationInventor: Hideaki Tanaka

Patent number: 7307548Abstract: A system and method for providing geographical information to a driver of a vehicle using radio frequency identification (RFID). Also provided is a traffic information supply system using RFID. The geographical information supply system includes a reader provided near a road which outputs a first signal and receives a second signal generated in response to the first signal; a tag that senses the first signal, converts information on a destination into the second signal in response to the first signal, and outputs the second signal. Also included is a first control unit which extracts and outputs the destination information from the second signal, receives geographical information to the destination, and supplies the geographical information to a driver. A server generates the geographical information corresponding to the destination information and outputs the generated geographical information to the first control unit.Type: GrantFiled: July 21, 2005Date of Patent: December 11, 2007Assignee: Samsung Electro-Mechanics Co., Ltd.Inventors: Kyung-bo Park, Woo-shik Kang, Si-gyoung Koo, Ji-hun Koo, Pierre Dehaut

Publication number: 20070279250Abstract: An existing-area calculating device of a vehicle surrounding information informing device calculates an existing area where a dead-ground obstacle approaching an own vehicle is likely to exist, based on own-vehicle traveling information detected by an own-vehicle traveling information detecting device and information of a dead-ground obstacle of another-vehicle obstacle information detected by an another-vehicle obstacle detecting device. Then, an informing device informs the exiting area of the dead-ground obstacle. Accordingly, the passenger (driver) can surely recognize the existence of the dead-ground obstacle to take any proper action to avoid a possible collision with the dead-ground obstacle, thereby improving the reliability of the vehicle surrounding information informing device.Type: ApplicationFiled: May 24, 2007Publication date: December 6, 2007Inventors: Takanori Kume, Haruhisa Kore, Shiyouta Kawamata

Patent number: 7302325Abstract: A vehicle drive assist system detects an intention of an own vehicle to turn right in an intersection and detects an oncoming vehicle waiting for a right turn on an oncoming lane in front of the own vehicle in the intersection. Further, the system establishes a detecting area in the vicinity of the right edge of the oncoming vehicle waiting and searches an oncoming vehicle traveling straight in the detecting area. When a new solid object is detected and the solid object is a part of the left corner of the solid object, the solid object is judged to be an oncoming vehicle traveling straight.Type: GrantFiled: April 15, 2004Date of Patent: November 27, 2007Assignee: Fuji Jukogyo Kabushiki KaishaInventor: Shinya Kudo

Patent number: 7302318Abstract: A method (200) is disclosed for designing an RNP approach for an aircraft at a particular runway (90). The method includes selecting a runway (201), gathering obstacle data for the obstacle evaluation area (202), selecting a VEB method and terms (204), laying out a preliminary approach, inducing a missed approach segment (206), calculating a preliminary obstacle clearance surface (208), calculating a momentary descent segment using a physical model of the aircraft (210), adjusting the obstacle clearance surface so that no obstacles intersect the surface (212), and optionally optimizing the approach by departing from the operator's standard procedures (214). Preferably, the obstacle clearance surface is adjusted so that it just touches an obstacle, without any object intersecting the surface, thereby providing an optimal decision altitude.Type: GrantFiled: March 10, 2006Date of Patent: November 27, 2007Assignee: Naverus, Inc.Inventors: Daniel A Gerrity, Jason E Dougherty, John H Andersen, Stephen D Fulton

Patent number: 7292921Abstract: A method for triggering restraint devices in which at least one collision-indicating signal is generated. From the moment that a collision is detected, temporally defined crash phases are specified, and, for every crash phase, a crash type and a crash severity are determined from the signal. The appropriate restraint devices are triggered as a function of the crash severity and/or the crash type.Type: GrantFiled: June 2, 2003Date of Patent: November 6, 2007Assignee: Robert Bosch GmbHInventors: Hermann Schuller, Gunther Lang, Josef Kolatschek, Sabine Aust, Thomas Lich, Armin Koehler, Klaus Mindner, Michael Roelleke

Patent number: 7292940Abstract: In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle's control in a reliable manner. When a set switch is turned on in the “cancel” state, the transition to the “in-control, inter-vehicle distance control” sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the “in-control, collision alarm” sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the “in-control, collision avoiding control” sub-state, and a collision avoiding control is performed.Type: GrantFiled: February 24, 2004Date of Patent: November 6, 2007Assignee: DENSO CORPORATIONInventors: Akira Isogai, Eiji Teramura, Takao Nishimura

Patent number: 7292920Abstract: The present invention relates to a method and a device for the lateral guidance of a vehicle. A warning device that outputs a warning signal when straying from a traffic lane is able to be turned off by a switching means when driving on a road that is not suitable for lateral guidance, in particular an inner-city road, and be turned on again when reaching a road that is suitable for lateral guidance.Type: GrantFiled: March 15, 2004Date of Patent: November 6, 2007Assignee: Robert Bosch GmbHInventors: Alexander Maass, Klaus-Guenther Fleischer
