Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] The present invention provides a navigation route calculation method and a navigation route calculation device, which calculate the navigation route including the road sections required by the user by providing the user with optional track sections. In this case, the user can go to the destination in the way he wants according to the newly opened road and the navigation path including the required road section, which is more convenient to use. The technical solution provided by the present invention will be described in detail below in conjunction with the drawings and specific embodiments. ...

The invention relates to a guidance technology and provides a guidance path calculation method and a guidance path calculation device, aiming at the defect that the prior guidance device can not calculate a guidance path comprising a novel opening road so as to cause inconvenient use under a condition that a map is not updated in the prior art. The guidance path calculation method comprises the following steps: receiving an input originating site and an input target site, searching a track road section positioned between the originating site and the target site and outputting; when receiving aselection command of the track road section, calculating the guidance path comprising the selected track road section based on the originating site and the target site and outputting. The invention also provides the guidance path calculation device. By providing the track road section to a user, the technical scheme can calculate the guidance path comprising the track road section required by theuser according to the originating site and the target site. Thereby, the user can head for the target site in a desired mode by referring to the guidance path comprising the required track road section and the novel opening road which is mastered by oneself, so that the technical scheme has more convenient use.
Description
technical field [0001] The present invention relates to navigation technology, and more specifically, to a navigation route calculation method and a navigation route calculation device. Background technique [0002] Vehicle navigation technology is an important branch of GPS (Global Positioning System, GPS) technology. The working principle of the car navigation system based on this technology is that the car navigation device receives the position coordinates transmitted by at least 3 satellites among the 24 GPS satellites around the earth, and compares them with the position coordinates recorded in the electronic map stored in the device itself. Matching, in order to determine the exact position of the navigation object equipped with the terminal in the electronic map. [0003] At present, navigation technology has been widely used in people's daily work and life. Users set search conditions such as starting point, destination, must-pass, and avoidance through the navigat...
