Problems solved by technology

[0005] Therefore, if the speed of the consumer reaches 120km / h on the expressway, when the automatic intersection zoom appears, the consumer has already missed this time, resulting in the problem of missing the intersection.

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] This embodiment provides a method for intelligent navigation, such as figure 1 shown, including steps:

[0041] Step S100, obtaining the driving speed in real time. In this embodiment, the speed of the vehicle is acquired before the vehicle reaches the intersection. Since the speed of the vehicle is constantly changing, the acquisition of the speed of the vehicle needs to be performed in real time, so that the next intelligent navigation operation can be performed according to the speed of the vehicle.

[0042] Step S200, according to the vehicle speed obtained in step S100, det...

Abstract

The invention discloses a method and system of intelligent navigation. The method comprises the following steps: acquiring vehicle speeds in real time; determining the range of the speeds according to the vehicle speeds, and finding a corresponding display scale according to the speed range to automatically determine a corresponding scale of a navigation map; and automatically displaying the navigation map by the navigation device. According to the invention, by setting a reaction time, calculating the speed range according to the acquired real-time vehicle speeds, and determining the corresponding scale of the navigation map, when driving to pass through a junction, the scale of the navigation map can be adjusted automatically in real time according to the vehicle speeds to leave enough reaction time for a user to make correct driving judgment of the junction ahead, thus the occurrence of missing the junction and detour can be avoided, and the usage is convenient for the user. The invention is simple and practicable, the development cost is very low, and the invention is suitable for large scale production and application.

Description

technical field [0001] The invention relates to the field of intelligent navigation, in particular to an intelligent navigation method and system. Background technique [0002] As the urban road network becomes more and more complex, navigation maps are used more and more. However, during the use process, due to the fixed scale of the customer, it is easy to miss the intersection, which causes the owner to miss the intersection on the highway. You can only walk a longer way around. [0003] The general map has been improved for this point, and the map intersection zoom function has been added. But at present, it only solves the problem of enlarging the intersection to a certain scale. If the speed of the vehicle is too fast or too slow, it still cannot effectively solve the above problems; [0004] The scale in the map is made exactly according to the actual size, therefore, one of his scale units determines his driving distance. Suppose the map scale is 1:25m, which mean...
