摘要： A vehicle control system which controls a vehicle in accordance with the curvature of a road as determined from map information comprising a set of coordinate points which represent the course of the road. A passable vehicle speed enabling the vehicle to pass through a plurality of nodes existing at predetermined distances within an operating section established on the road ahead of a given vehicle position is calculated on the assumption that a voluntary speed reduction has been conducted. The radii of a first virtual turning locus and a second virtual turning locus produced at a predetermined lateral acceleration are calculated based on the passable vehicle speeds at the nodes. A passable zone, a warning zone and an automatic speed-reducing zone are established based on the first and second virtual turning locus radii. If any of the nodes ahead of the virtual vehicle position exists in the warning zone, a warning is provided to the driver. If any of the nodes ahead of the virtual vehicle position exists in the automatic speed-reducing zone, automatic speed reduction of the vehicle is carried out.

摘要： A vehicle position is determined and four reference coordinate points N.sub.1, N.sub.2, N.sub.3 and N.sub.4 are extracted at predetermined distances on a road output from a CD-ROM or an IC card, and an angle .theta. of turning of the vehicle from the coordinate point N.sub.2 to the coordinate point N.sub.3 is calculated according to an expression, .theta.=(.theta..sub.1 +.theta..sub.2) from an angle .theta..sub.1 formed by a vector V.sub.12 between the points N.sub.1, N.sub.2 and a vector V.sub.23 between the points N.sub.2, N.sub.3 and an angle .theta..sub.2 formed by the vector V.sub.23 between the points N.sub.2, N.sub.3 and a vector V.sub.34 between the points N.sub.3, N.sub.4. A steering angle permitting the vehicle to safely pass through a curve is calculated based on the turning angle .theta. and a vehicle speed V.sub.0, and a passable vehicle speed permitting the vehicle to safely pass through the curve is calculated based on a radius R=a/.theta. of curvature of the curve. Thus, the servicing of a conventional infrastructure requiring increased equipment and maintenance costs is not required, and it is possible to carry out a vehicle control based on a minimum amount of data storable in a CD-ROM or an IC card.

摘要： A driving control system for a vehicle includes a map information output device for outputting a map, a vehicle position detecting device for detecting a vehicle position of a subject vehicle on the map, a vehicle speed detecting device for detecting a vehicle speed, a passable area determining device for determining a passable area on the map on the basis of the detected vehicle speed, and a passability/impassability judging device for deciding that the vehicle may pass through a portion of road when a road which is in front of the vehicle position in a traveling direction is included in the passable area on the map. The road which is in front of the vehicle position in the traveling direction is compared with the determined passable area, and when the road is included in the passable area, it is decided that the vehicle may pass through the portion of road. Thus, it is possible to properly judge whether or not the vehicle may pass through the portion of road by a simple calculation not including a complex and poor-accuracy calculation of the radius of curvature of a road.

摘要： The present invention is directed to a system and method that includes a vehicle that exchanges information with the remote location by way of a communication network. A remote server transmits vehicle-related information to the vehicle by way of a communication system. Information may also be broadcast to and received by the vehicle by way of a broadcast communication system. A receiver of the vehicle provides user access to only a subset of the broadcast information based on user preferences of a user profile. The user may update the user profile by accessing and updating it at either the vehicle or by accessing a database. The user may access the database through a network, such as the Internet. The vehicle also selectively transmits vehicle-related information to the remote location when a predetermined event occurs. The vehicle-related information is compiled and analyzed at the remote location, and the analyzed information is transmitted back to the vehicle.

摘要： Traffic information, including traffic flow information and traffic incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be presented to a user on a user display in the vehicle. The traffic information may be presented to the user in several circumstances, either as cued by the user, or automatically presented by the traffic management system. The user display may also automatically display traffic flow and traffic incident information for the direction that the user is traveling or along a route calculated by the navigation device. Further, a window displaying information about an upcoming traffic incident such as distance to the incident and incident details may automatically appear in the user display. Alternately, the user may select a roadway, freeway, or area for which traffic information is desired.

摘要： Traffic information, including flow information and incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be used in route calculation by a navigation device. The navigation device may recalculate a route based on anticipated user error. Alternatively, the navigation device may recalculate a route using received traffic information triggered by the receipt of a traffic information update, or triggered by the passage of an amount of time. The broadcast rate of traffic information updates may vary temporally (providing more frequent updates during peak commute times) or geographically (providing more frequent updates to metropolitan areas with increased traffic information needs). If route calculation is triggered by an elapsed amount of time, the amount of time may vary to be shorter during peak commute times. Additional route calculation techniques allow the incorporation of historical traffic information or the use of the most recent traffic information if incomplete traffic information is available. Still further route calculation techniques may calculate a best route by avoiding zigzagging or evaluating an assigned cost of a potential route.

摘要： The present invention is directed specifically to methods for reducing the bandwidth requirements for broadcasting traffic information to a vehicle navigation system. The traffic information broadcast to the system using the bandwidth conserving methods of the present invention generally includes traffic flow information and traffic incident information. In one embodiment, the vehicle navigation system filters traffic information to a certain range to expedite traffic calculation, to save on processing hardware, and to reduce bandwidth needs. Alternately, bandwidth conservation may be achieved by providing weight factors and threshold prioritizing when a broadcast limit is close to being reached or exceeded. In another embodiment, bandwidth reduction is achieved by not broadcasting free-flow traffic information and/or displaying only traffic information that indicates a traffic problem. Another method of the present invention to reduce bandwidth needs is directed to reducing broadcast of static traffic information.
