Patent number: 7308349Abstract: A vision-based occupant classification method utilizes a static classification routine for achieving highly accurate occupant classification, a dynamic detection routine for quickly responding to changes in occupant position, and a category state change routine for detecting potential changes in occupant category. The static classification routine determines an initial classification of the occupant, after which the dynamic detection routine monitors for changes in occupant position and the category state change routine monitors for a potential change in occupant category. If category state change routine detects a potential change in occupant category, the static classification routine is re-executed to re-classify the occupant. The category state change routine identifies a composite optical flow vector associated with occupant movement, and detects a potential change in occupant category when the composite flow vector crosses one or more pre-defined entry/exit motion gates.Type: GrantFiled: June 6, 2005Date of Patent: December 11, 2007Assignee: Delphi Technologies, Inc.Inventors: Hongzhi Kong, John R.

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: 7289022Abstract: A communication system for communicating between a tire/wheel assembly and a body of a vehicle of a construction in which the tire/wheel assembly is supported by the vehicle body, has a i) wheel-side communication device that is mounted to the tire/wheel assembly and rotates together with the tire/wheel assembly, and ii) a body-side communication device that is mounted in a fixed position to the vehicle body. The communication system performs communication between the wheel-side communication device and the body-side communication device according to a predetermined rotational position of the tire/wheel assembly.Type: GrantFiled: May 25, 2004Date of Patent: October 30, 2007Assignee: Toyota Jidosha Kabushiki KaishaInventors: Atsushi Ogawa, Shinichi Tomioka

Patent number: 7283901Abstract: Systems and methods are provided for identifying a position of a head of a vehicle occupant from a plurality of images of a vehicle interior. Image data is translated from the plurality of images to produce a virtual side view image of the vehicle interior (162). A largest grouping of pixels in the side view image having values within a desired range is identified (164). The grouping includes a plurality of pixel columns. A contour including uppermost pixels of each pixel column is produced and peaks are located within the contour (166). The contour peaks are analyzed according to a heuristic voting algorithm to identify a peak location associated with the head of the vehicle occupant (172).Type: GrantFiled: January 13, 2005Date of Patent: October 16, 2007Assignee: TRW Automotive U.S. LLCInventors: Yun Luo, Jon K.

Patent number: 7268704Abstract: An input device in a vehicle and a method for occupant classification, in which an input regarding occupant classification is requested from the driver or some other user. This input is compared with an automatically produced occupant classification, and depending on this comparison a warning is issued, an occupant classification is communicated to the control unit for restraining devices, and/or a new input is requested.Type: GrantFiled: September 20, 2002Date of Patent: September 11, 2007Assignee: Robert Bosch GmbHInventors: Martin Schmied, Frank Mack
