Embodiment Construction
[0024] 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.
[0025] In the embodiment of the present invention, after receiving the surrounding information retrieval instruction, the current location of the navigation object is obtained, and the surrounding information is retrieved with the current location of the navigation object as the center, and the points of interest in the retrieved surrounding information are prompted and judged. Whether the retrieval interval preset by the system has arrived, and if so, return to the step of surrounding information retrieval.

The invention is applicable to the navigation technical field, which provides a search method, a device and a navigation aid which are used for peripheral information in driving. The method comprises following step: receiving a search instruction of the peripheral information, obtaining a current position of a navigation object, searching the peripheral information which uses the current location of the navigation object as center, prompting an interest point of the peripheral information which is searched and the operation instruction of the interest point, the operation instruction of the interest point including navigation to the interest point and return the broadcast of the interest point, judging whether a searching interval which is preset by a system is obtained or not, if obtained, returning to the step indexing the peripheral information, in the newly promoting process, deleting the broadcasted interest point in the last search result, and broadcasting the interest point unbroadcasted. The invention solves the problem that the current technology can not correct a searching result according to a shift position of a navigation object when peripheral information is searched.
Description
technical field [0001] The invention belongs to the technical field of navigation, and in particular relates to a method, a device and a navigation device for searching peripheral information during travel. Background technique [0002] Global Positioning System (GPS) is a high-tech positioning product that can achieve high precision, all-weather, high efficiency, multi-function, easy operation and affordable price. [0003] In the prior art, when using the GPS navigation system to retrieve the surrounding information of the navigation object, after the user issues an instruction to retrieve the surrounding information, the system lists the results or lists the names and destinations of various surrounding information points on the electronic map. The distance of the current location is displayed or voice broadcast to the user, but if the navigation object is in the process of fast travel, the retrieved result may be too far away from the latest current location of the navig...
