摘要:
The present invention provides a route calculation device, a navigation device, a route calculation method, and a navigation device that can calculate a route that allows a user to arrive at a destination or a stop-off point within a determined time period. The route calculation device according to the present invention includes a communication available hours acquisition unit 11 that acquires communication available hours of a plurality of branch stations that establish communication with a mobile station, a reference time acquisition unit 12 that acquires a reference time, a road information acquisition unit 13 that acquires time information of a road section, and a route calculation unit 31 that calculates a first travel route that offers the shortest required time for stopping by the branch stations based on the communication available hours, the reference time, and the time information of a road section.
摘要:
A system for autonomously navigating a vehicle along a road segment is disclosed. The system may have at least one processor. The processor may be programmed to receive from an image capture device at least one image representative of an environment of the vehicle. The processor may also be programmed to analyze the at least one image to identify at least one recognized landmark. Further, the processor may be programmed to determine a current location of the vehicle relative to a predetermined road model trajectory associated with the road segment based, at least in part, on a predetermined location of the recognized landmark. In addition, the processor may be programmed to determine an autonomous steering action for the vehicle based on a direction of the predetermined road model trajectory at the determined current location of the vehicle relative to the predetermined road model trajectory.

A vehicular drive assist system performs drive assist for a vehicle traveling in each predetermined area while receiving a feedback on evaluation relating to ease of travel on a road in each of the areas. In the system, a management center performs evaluation of ease of travel on a road for each of the areas on the basis of information obtained from the vehicle and feeds back the evaluation result to the vehicle. In this case, a variation width of the evaluation relating to ease of travel is restricted on a basis of static factors of road environment for each of the areas.

A vehicle (6, 8) and method of operating a vehicle (6, 8) in a vehicle traffic control system (2) includes receiving a grid projection from a grid generator (10), generating a navigation output, transmitting the navigation output to the vehicle traffic control system (2), receiving the vehicle traffic control plan from the vehicle traffic control system (2), and operating the vehicle (6, 8).
摘要:
A method of stitching converging path segments to aesthetically label Y-intersections, path bifurcations or splits in roads or the like entails determining which pair of adjacent path segments subtend the largest angle. The path segments subtending the largest angle are reconstructed (stitched together) and a single instance of the label is then rendered along the reconstructed path. Although this stitching can be performed on the client device, prestitching server-side is even more efficient in terms of economizing over-the-air bandwidth and onboard processing resources.
