Patent number: 10871375Abstract: A method for operating a navigation system of a vehicle includes providing one or more dedicated route options, transmitting a first signal for requesting one or more route options to a vehicle-external data processing device, and receiving a second signal from the vehicle-external data processing device, where the second signal identifies one or more route options provided by the vehicle-external data processing device for route calculation. The method also includes outputting at least one of the dedicated route options and at least one of the route options identified in the second signal, and detecting at least one input of a user of the navigation system corresponding to a selected one of the outputted route options.Type: GrantFiled: September 17, 2018Date of Patent: December 22, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Marcello Tava

Patent number: 10768005Abstract: A system and method for navigating a vehicle includes a management unit (server) arranged outside of the vehicle for centrally storing traffic information and traffic rules relating to vehicle information. The traffic rules relate, for example, to road closures and restrictions based on vehicle type. A detection unit has an interface for detecting vehicle information of the vehicle, such as at least one vehicle identification number, and is designed to transmit the detected vehicle information of the vehicle to the managing unit. A computing module generates navigation information based on traffic rules stored on the managing unit and vehicle information. The generated navigation information is output in the vehicle by a navigation unit (client).Type: GrantFiled: September 14, 2018Date of Patent: September 8, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Marcello Tava

Patent number: 10145695Abstract: The route from a prescribed starting node to a prescribed destination node is determined on the basis of digital map data stored in a memory unit such that, for possible expansion of a respective current node, total costs are determined for the current node on the basis of a sum of edge costs for an optimum route from the starting node to the current node and a destination-node-related heuristic value for the current node and a prescribed destination-node-related correction value. The destination-node-related correction value is in this case representative of a mean value for cost ratios for respective nodes in a prescribed set, wherein the respective cost ratios are dependent on the edge costs of the connections that are situated between the current node and the respective node in the set and that represent an optimum route between the current node and this node in the set and on a heuristic value for the current node in relation to this node in the set.Type: GrantFiled: December 18, 2015Date of Patent: December 4, 2018Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Marcello Tava

Patent number: 9188455Abstract: A navigation system has an interface for accessing a memory unit, in which an electronic road map is stored with a large number of road sections, each of which has at least one first cost element assigned thereto, and has a computer unit, which is designed such that at least one second cost element is assigned or will be assigned to at least some of the road sections. In order to compute a route, a cost value is assigned or will be assigned to each of the road sections, wherein the computation of the cost value for the first road sections is based in each case on the first and the second cost element and for the second road sections is based in each case on the first and not on the second cost elements.Type: GrantFiled: March 8, 2013Date of Patent: November 17, 2015Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Marcello Tava

Patent number: 9170121Abstract: A motor vehicle navigation system and method uses an output device for the acoustic output of driving maneuver information and a processor device which is equipped such that a route to be traveled is determined. Driving maneuver information is determined based on the route to be traveled and on an actual position. An alternate route is computed, assuming that the determined driving maneuver information is not observed. As a function of the difference between the route and the alternate route, particularly with respect to the expected driving time, driving distance and/or driving cost, the driving maneuver information is either acoustically emitted or not.Type: GrantFiled: October 13, 2009Date of Patent: October 27, 2015Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Marcello Tava, Roman Berger

Publication number: 20130253826Abstract: A navigation system includes a memory in which information concerning road sections and information concerning time-dependent traffic restrictions are stored such that time-dependent traffic restrictions are assigned to a portion of the road sections. A route computation process is set up such that, when computing a route, the memory is accessed in order to compute a route based on information concerning road sections and based on information concerning time-dependent traffic restrictions. When computing the route, information concerning time-dependent traffic restrictions for a first portion of the road sections, to which information concerning a time-dependent traffic restriction is assigned, is taken into account and, information concerning time-dependent traffic restrictions for a second portion of the road sections, to which information concerning a time-dependent traffic restriction is assigned, is not taken into account.Type: ApplicationFiled: May 17, 2013Publication date: September 26, 2013Applicant: Bayerische Motoren Werke AktiengesellschaftInventor: Marcello TAVA
