System For Using Speech Recognition With Map Data

View page
US Patent:
6598016, Jul 22, 2003
Filed:
Oct 20, 1998
Appl. No.:
09/175657
Inventors:
Walter B. Zavoli - Palo Alto CA
Hongche Liu - Fremont CA
Assignee:
Tele Atlas North America, Inc. - Menlo Park CA
International Classification:
G10L 1504
US Classification:
704251, 704277
Abstract:
A system is disclosed for using speech recognition with map data. For example, a user could state a location. The system will recognize the words spoken and find the location on a map using an electronic map database. The map can be displayed such that the location is depicted. Alternatively, the user could state two locations. The system will recognize the words spoken, find both locations on the map using an electronic map database, determine a path between the locations and report that path to the user.

Non-Perspective Variable-Scale Map Displays

US Patent:
20060267803, Nov 30, 2006
Filed:
May 24, 2006
Appl. No.:
11/440329
Inventors:
Darrell Mathis - Menlo Park CA, US
Tsia Kuznetsov - Cupertino CA, US
Walter Zavoli - Palo Alto CA, US
Assignee:
Tele Atlas North America, Inc. - Lebanon NH
International Classification:
G08G 1/123
US Classification:
340995150
Abstract:
Map displays have been an important element in the feature set of in-car navigation systems. Actually, with modem equipment extending such system functionality to personal digital assistants (PDAs) and cellular telephones, virtually all travelers may use and benefit from the present invention. Early digital displays were monochrome, single-line-vector, planar representations. Color, area fill, scale-dependent attribute selection, labeling, heading-up rotation, line thickness, signs and icons have all been added to make the display more informative and intuitive. Still today, the designer is challenged to provide a more informative, less distracting display to serve the multitasking driver. More recently, perspective view and 3D objects have gained popularity because of their added utility as well as aesthetic appeal. Just as the planar map is a special case of the perspective map, perspective is a special case of the variable-scale map. This disclosure offers some approaches to the use of non-perspective continuous variable-scale maps to solve inherent problems of more conventional navigation map displays.

System And Method For Vehicle Navigation And Piloting Including Absolute And Relative Coordinates

View page
US Patent:
20080243378, Oct 2, 2008
Filed:
Feb 20, 2008
Appl. No.:
12/034521
Inventors:
Walter B. Zavoli - Palo Alto CA, US
Assignee:
TELE ATLAS NORTH AMERICA, INC. - Lebanon NH
International Classification:
G01C 21/26
G01C 21/00
US Classification:
701209, 701208
Abstract:
A navigation system for use in a vehicle. The system includes an absolute position sensor, such as GPS, in addition to one or more additional sensors, such as a camera, laser scanner, or radar. The system further comprises a digital map or database that includes records for at least some of the vehicle's surrounding objects. These records can include relative positional attributes and traditional absolute positions. As the vehicle moves, sensors sense the presence of at least some of these objects, and measure the vehicle's relative position to those objects. This information, together with the absolute positional information and the added map information, is used to determine the vehicle's location, and support features such as enhanced driving directions, collision avoidance, or automatic assisted driving. In accordance with an embodiment, the system also allows some objects to be attributed using relative positioning, without recourse to storing absolute position information.

View page
US Patent:
20090138497, May 28, 2009
Filed:
Nov 6, 2008
Appl. No.:
12/289888
Inventors:
Walter Bruno Zavoli - Palo Alto CA, US
Hans Ulrich Otto - Hildesheim, DE
International Classification:
G06F 17/30
US Classification:
707102, 7071041, 707E17018
Abstract:
At least one embodiment of a method is described including: (1) collecting probe sensor data in an area containing roads and other drivable features; (2) processing the probe sensor data in a first manner so as to create a geospatial map database including road segments, and in a second manner to derive a subset of data related to at least one segment within the geospatial map database and being indicative of an attribute thereof, (3) statistically processing the subset data per road segment to determine one or more inferred attributes thereof, (4) comparing the created geospatial map database, in particular the road segments identified therein and said inferred attributes thereof with a pre-existing geospatial map database containing road segments and attributes thereof, and where an inconsistency in the presence or absence of a road segment, or in its geometry or topology, or in any of its attributes, is identified, (5) effecting a further action, being one of: (a) Generating a change notification, (b) Generating an alert, (c) Generating a change request, the ultimate operation of such further action being the eventual update of the pre-existing geospatial map database such that the former attribute is replaced with the inferred attribute, and/or the insertion, deletion or correction, as far as geometry and topology is concerned, of the road segment. Alternative methods are also described.

System And Method For Map Matching With Sensor Detected Objects

View page
US Patent:
20090228204, Sep 10, 2009
Filed:
Feb 3, 2009
Appl. No.:
12/365119
Inventors:
Walter B. Zavoli - Palo Alto CA, US
Marcin Michal Kmiecik - Lodz, PL
Stephen T'Siobbel - Merelbeke, BE
Volker Hiestermann - Hanover, DE
Assignee:
TELA ATLAS NORTH AMERICA, INC. - Lebanon NH
TELA ATLAS B.V. - BX 'sHertogenbosch
International Classification:
G01C 21/26
US Classification:
701208
Abstract:
A system and method for map matching with sensor detected objects. A direct sensor and object matching technique can be used to disambiguate objects that the driver passes. The technique also makes it possible for the navigation system to refine (i.e. improve the accuracy of) its position estimate. In some embodiments, a camera in the car can be used to produce, dynamically in real time, images of the vicinity of the vehicle. Map and object information can then be retrieved from a map database, and superimposed on those images for viewing by the driver, including accurately defining the orientation or the platform so that the alignment of the map data and the image data is accurate. Once alignment is achieved, the image can be further enhanced with information retrieved from the database about any in-image objects. Objects may be displayed accurately on a map display as icons that help the driver as he/she navigates the roads.
