Location sharing and tracking using mobile phones or other wireless devices

A method computer aided dispatching. The present method includes providing a display 510 having a first display segment 530. The first display segment 530 includes a digitized representation of a selected area from a raster map, intelligent area data superimposed upon the selected area to provide intelligence, and a user locatable mark 520. The user locatable mark 520 defines a mobile unit position based upon a first value and a second value. The present method also includes using a dispatch system 811 operably coupled to the display. The dispatch system 811 includes order data from customers. A portion of the order data is transferred from a data acquisition 801, 808 device to the mobile unit 610.

Method and apparatus for tracking vehicle location

A forward-facing vision system for a vehicle includes a forward-facing camera disposed in a windshield electronics module attached at a windshield of the vehicle and viewing through the windshield. A control includes a processor that, responsive to processing of captured image data, detects taillights of leading vehicles during nighttime conditions and, responsive to processing of captured image data, detects lane markers on a road being traveled by the vehicle. The control, responsive to lane marker detection and a determination that the vehicle is drifting out of a traffic lane, may control a steering system of the vehicle to mitigate such drifting, with the steering system manually controllable by a driver of the vehicle irrespective of control by the control. The processor, based at least in part on detection of lane markers via processing of captured image data, determines curvature of the road being traveled by the vehicle.

Vision system for vehicle

A vehicular vision system includes a camera having a lens and a CMOS photosensor array having a plurality of photosensor elements. The camera is disposed at an interior portion of a vehicle equipped with the vehicular vision system. The camera one of (i) views exterior of the equipped vehicle through the windshield of the equipped vehicle and forward of the equipped vehicle and (ii) views from the windshield of the equipped vehicle into the interior cabin of the equipped vehicle. A control includes an image processor that processes image data captured by the photosensor array. The image processor processes captured image data to detect an object viewed by the camera. The photosensor array is operable at a plurality of exposure periods and at least one exposure period of the plurality of exposure periods is dynamically variable.

Provided is a fully automated web service with location based services generally involved in transmission of situational location dependent information to automatically located mobile receiving data processing systems. The web service communicates with a receiving data processing system in a manner by delivering information to the device when appropriate without the device requesting it at the time of delivery. There are varieties of configurations made by different user types of the web service for configuring information to be delivered, and for receiving the information. The web service maximizes anonymity of users, provides granular privacy control with a default of complete privacy, and supports user configurable privileges and features for desired web service behavior and interoperability. The web service is fully automated to eliminate human resources required to operate services. Integrated with the web service are enhanced location based services providing map solutions, alerts, sharing of novel services between users, and complete user control for managing heterogeneous device interoperability through the web service.

System and method for anonymous location based services

In areas where composite intersection traffic regulation exits, nodes and links for use in the conventional network are separated into a plurality of nodes and links, respectively. For example, one node is separated into N1a to N1c, and one link is separated into L1a to L1c. Then, the whole road network is represented by separating the network into a road network (L1a, L2a, L3a, L4a, L5a, N1a, N2a) in view of entering links (L1a, L3a) which the composite intersection traffic regulation does not affect, and road networks α (L1b, L2b, L3b, L4b, N1b, N2b) and β (L1c, L2c, L3c, L5c, N1c, N2c) in view of entering links (L4b, L5c) which the composite intersection traffic regulation affects, and one-way traffic regulations are set on suitable links to allow representation of the composite intersection transfer regulation. Use of such map data enables selection compliant with the composite intersection traffic regulation without specific processing at the time of search processing.

Method and apparatus for searching a route

A vehicle position calculation unit (1) calculates a position of a vehicle on a plan view, and an estimate locus calculation unit (2) calculates an estimate movement locus of a vehicle body when the vehicle is moved at a maximum steering angle with respect to the vehicle position, and a display unit (3) displays the vehicle position calculated by the vehicle position calculation unit (1) together with the estimate locus of the vehicle body calculated by the estimate locus calculation unit (2). Thus, even a beginner driver of the vehicle can easily and quickly park the vehicle with accuracy and safety while monitoring the estimate movement locus of the vehicle on the display screen.

Parking conduct device and parking conduct method

A terminal device for reading a cartographic file in which updating one cartographic file does not require updating cartographic files in the neighboring units For this purpose, cartographic files which represent respective units extracted by dividing a map into a plurality of areas each comprise node records generated for respective nodes and link records generated for respective links Given node records contain coordinate information about neighboring nodes which define connections of roads between its unit and a neighboring unit The cartographic files are stored in a first storage device The data processing portion executes a process of searching for a route by using the cartographic files During the route search, the data processing portion traces the connection from a road in one unit to a road in another, neighboring, unit on the basis of the coordinate information about the neighboring nodes of said one unit and said neighboring another unit

Data structure of digital map file

A correct vehicle position is detected even when the road data to be used in the map match computation includes errors of partial shape. When the matching computing operation of a running locus and the road data obtained from the outputs of a bearing sensor and a distance sensor and a non-match region has been effected by the map match computing means, the non-matching region of the road data and the running locus is detected. The positional error detection caused by errors of the road data is effected by prohibiting map integration.

Vehicle position detecting apparatus which comensates for errors in road map data matching operation

In a route selection process, an optimal route searcher 5 refers to a traffic light flag included in route selecting data stored in a second storage 4 to see whether a target intersection has any traffic light or not When the optimal route searcher 5 determines that the target intersection has a traffic light s, a traffic light cost calculator 6 calculates a traffic light cost relevant to a waiting time due to the traffic light s Based on the traffic light cost thus calculated by the traffic light cost calculator 6 , the optimal route searcher 5 calculates a passage cost relevant to a time taken for passing the target intersection In this manner, with consideration for the waiting time due to the traffic light, a time for going through an entire route can be estimated with higher correctness, thereby rendering the route thus searched more optimal
