摘要： A system and method for storing data in a computer-readable database to represent curved geographic features. The database can be used in a navigation system. A computable function is used to define a curved line that represents the curved geographic feature. The computable function may be a polynomial equation whose shape is defined by its coefficients. In one embodiment, the polynomial equation is a type of spline curve, in particular a Bezier curve whose shape is defined by control points. The coefficients of the polynomial equation are associated with data representing the curved geographic feature. In the case in which the polynomial equation is a Bezier curve, the control points for generating the Bezier curve are associated with the data representing the curved geographic feature. These control points are stored in the database and are used in displaying the curved geographic feature. Use of a computable function to represent curved geographic features and storing parameters to be used by the computable function has the potential for significantly reducing the storage requirements for representing curved geographic features in a database. According to a further aspect, data identifying the normalized control points are stored in a data array and references into the data array are associated with data representing the curved geographic features, thereby enabling curved geographic features to be represented in space efficient manner.

摘要： The invention provides a method and system for providing route guidance and other information from a base unit to a remote unit in response to a request from the remote unit. A query is formatted at the remote unit, the query including the request, and is transmitted from the remote unit to the base unit. Requested route guidance information is calculated at the base unit in response to the query, using a large up-to-date database located at the base unit. A response to the query is formatted at the base unit, the response including route guidance information. The response is then transmitted from the base unit to the remote unit for display. The transmission is made in a compact form through the use of maneuver arms and combined maneuver arms and through the use of tokenized forms. A maneuver arm represents a road at an intersection, for depiction on a display, by one or two endpoint coordinates. The tokenized forms are expanded at the remote unit into textual driving instructions for each of one or more languages. In addition, the amount of information available at a remote unit can be increased by providing the remote unit with information from the base unit which is not adequately covered by any databases on-board the remote unit.

摘要： A system and method for providing updated geographic data for use by a navigation application program. The navigation application program is at a first version level and uses geographic data in a geographic database. An updated geographic database is provided to the navigation application program. The updated geographic database is at a second version level which is later than the first version level. Also provided to the navigation application program are one or more replacement routines. These replacement routines may be stored with the updated geographic database on a computer-readable medium or may be provided separately. The one or more replacement routines are used by the navigation application program either at initialization or during runtime. The one or more replacement routines are called to access or use the data in the updated geographic database. The one or more replacement routines are preferably in an interpretive language and executed by a virtual processor. The virtual processor may be part of the navigation application program. The one or more replacement routines can be used by the navigation application program thereby enabling the navigation application program which is at the first version level to use the updated geographic data which is at second version level.

摘要： A system for updating, enhancing and/or refining a geographic database. A geographic database includes data representing physical features in the geographic region, and, optionally, attributes of such features. The system includes a plurality of data collecting sensors. Each of the data collecting sensors is installed in a separate one of a plurality of vehicles each of which is capable of traveling on roads in a geographic region. Each of the data collecting sensors provides outputs indicative of one or more features in the geographic region as the vehicle in which it is installed travels on the roads in the geographic region. A computer program executes a feedback process on the geographic database using the outputs of the data collecting sensors. A first part of the feedback program compares the outputs of the data collecting sensors to the data identifying the physical features and provides results representative of the comparisons. A second part of the feedback program is responsive to the results from the first part and determines the significance of the comparisons. A third part of the feedback program modifies the data in the geographic database based upon the significance determined by the second part of the program. The data in the geographic database representing physical features in the geographic region are updated, enhanced, or refined based upon the significance determined by the feedback program. The data which has been updated, enhanced, or refined, is used to provide updated, enhanced, or refined data in end-user vehicles, some of which may include the vehicles in which data collecting sensors have been installed. Sensors in end-users' vehicles are calibrated to high levels of accuracy using the data which has been updated, enhanced or refined using a feedback process. Further, an out-of-calibration sensor in an end-user's vehicle is detected and re-calibrated using the data which has been updated, enhanced or refined using a feedback process. Using a feedback process, levels of confidence are assigned to data in the geographic database representing physical features in the geographic region, thereby enabling the data to be used for purposes requiring high levels of confidence.

摘要： A computing architecture for a motorized land-based vehicle is disclosed. The computing architecture includes a data network comprised of a plurality of interconnected processors, a first group of sensors responsive to environmental conditions around the vehicle, a second group of sensors responsive to the vehicle's hardware systems, and a map database containing data that represent geographic features in the geographic area around the vehicle. A vehicle-environment modeling program, executed on the data network, uses the outputs from the first and second groups of sensors and the map database to provide and continuously update a data model that represents the vehicle and the environmental around the vehicle, including geographic features, conditions, structures, objects and obstacles around the vehicle. Vehicle operations programming applications, executed on the data network, use the data model to determine desired vehicle operation in the context of the vehicle's environment. A driver interface receives the vehicle driver's input. Vehicle control programming, executed on the data network, receives outputs from the vehicle operations programming applications and the driver interface, determines a resolved operation for the vehicle's hardware systems and provides output commands indicative, thereof. The vehicle operations programming applications may include adaptive cruise control, automated mayday, and obstacle and collision warning systems, among, others. Also disclosed is a new computing architecture that organizes the applications and systems in the vehicle into two groups: driver assistance systems and mobile services and information systems. Also disclosed is a drive recorder that maintains records of the statuses of all vehicle systems and of the driver.
