    Abstract: A multi-mode route guidance system and a corresponding method for same include a device to determine a present position, and an input device (111) for inputting a destination position. A map database (115) provides memory capable of storing a first type of record (225) that has topology and connectivity information (227), and a second type of record (217) that has topology, connectivity, and traffic flow restriction information (227, 229). A route guidance device (101) retrieves selected records (217, 219, 221, 223, 225) from the map database (115), determined by the specified destination position and the present position of a traveler. The route guidance device (101) uses a selected record of the first type (225) to provide ground track guidance cues (601) to the traveler, and a selected record of the second type (217) to provide maneuver instruction guidance cues (501) to the traveler.

    Abstract: A vehicle (100) includes vehicle systems (11-13) coupled to a vehicle bus (10) and user devices (40-60) coupled to a user bus (30), the user bus coupled to the vehicle bus by a gateway (20). The user bus transports user information and the vehicle bus transports vehicle information. Based on one or more gateway rules, the gateway transports vehicle information to the user bus for the benefit of target user devices. Also based on these gateway rules, the gateway transports user information to the vehicle bus for the benefit of target vehicle systems. The gateway rules are programmed by both user devices and vehicle systems as follows: First, a proposed rule is provided (303) to the gateway. Second, the gateway determines (305) when to accept the proposed rule based on a variety of factors. Third, when the proposed rule is accepted, the proposed rule becomes (307) a gateway rule.

    Abstract: Un système de captage d'une précision améliorée, pour la navigation de véhicules, utilise un capteur tel qu'un compas (515) ou un compteur kilométrique (509) pour détecter un paramètre de navigation d'un véhicule. Un signal est produit par le capteur (509), lequel signal comporte une composante erronée. Un dispositif de reconnaissance dépourvu de modèle, tel qu'un ordinateur de navigation à inférence floue (501) est utilisé pour identifier le comportement erroné. Après que cette identification ait été effectuée, le capteur peut être ré-étalonné, ou doté d'un coefficient de précision. Le signal est alors combiné avec d'autres mesures du même paramètre et soumis à une mise en correspondance topographique avant que le variable de navigation final n'en soit déduit.
