Embodiment Construction
[0048] The "method and device for target navigation" of the present invention can filter out several secondary targets within the set range, and perform the most suitable target screening through the set parameters, and integrate the best target on the final target route. Secondary target location; see figure 1 As shown, the target navigation method is mainly applied in the navigation system, including a target planning process 1 and a car navigation process 2, and the target planning process 1 includes the following steps.
[0049] Step 11 of main target route planning: setting a main target to plan a main target route from the vehicle to the main target;
[0050] Step 12 of determining the predetermined range: in the main target route, determine a predetermined range according to the current position and direction of travel of the vehicle, and the radius of the predetermined range is automatically changed according to the driving location, such as urban areas, the range is s...

The invention discloses a method and a device for target navigation, which comprise a navigation device arranged on a vehicle. The navigation device is provided with a navigation system. The navigation system comprises a plurality of secondary targets. The method for target navigation comprises the following steps: setting a main target to plan a main target route from the vehicle to the main target; in the main target route, determining a predetermined range according to the current position and traveling direction of the vehicle; comparing the plurality of secondary targets to screen at least a secondary target positioned in the predetermined range; selecting an optimized secondary target according to the shortest route distance from the vehicle to the at least a secondary target; and planning an optimized secondary target route to navigate to the optimized secondary target. The method and the device for target navigation not only can screen the plurality of secondary targets in the predetermined range and integrate the optimized secondary target position on a final destination route, but also have the function of receiving remote real-time information.
Description
technical field [0001] The present invention relates to a target navigation method and device, in particular to a navigation method and device that can actively search for several targets and screen out a most suitable suggested target through parameters. Background technique [0002] Please refer to China Taiwan Patent Application No. 094122921 "Searching Attraction Device and Its Method" patent. It is set in the navigation system. The navigation system provides the navigation path and provides the user with the option of the scenic spot category. It includes: a limited range module It is used to generate a predetermined range corresponding to the navigation path, and then the search module searches for at least one scenic spot matching the scenic spot category within the predetermined range; then, the analysis module sets weights according to the user's current location and each scenic spot, and forms a scenic spot weight window ; Finally, the display module displays the s...
