Abstract

The invention is applicable to the technical field of automobile, and provides an automobile navigation method, device and system based on a mobile terminal. The automobile navigation method includes steps that the mobile terminal generates a corresponding positioning command according to a navigation request of a user; the mobile terminal sends the positioning command to an on-board host computer connected with the mobile terminal; the on-board host computer acquires a coordinate of the automobile location from the connected positioning module according to the positioning command, and sends the acquired coordinate to the mobile terminal; the mobile terminal outputs the automobile location and the navigation information according to the coordinate, the pre-stored destination information and the map data, so that the automobile navigation is realized through the mobile terminal, the on-board host computer and the positioning module located in the automobile; the accuracy of the automobile navigation is not reduced while the automobile navigation is realized by means of the mobile terminal; moreover, the navigation requirement on hardware configuration of the automobile is reduced.

Description

technical field [0001] The invention belongs to the technical field of navigation, and in particular relates to a mobile terminal-based car navigation method, device and system. Background technique [0002] At present, car navigation and smart phone navigation are quite popular, and the competition in the car navigation industry is becoming more and more fierce. The price of navigation products is a very important manifestation of competition. At the same time of navigation, it is also necessary to pay a large price for the cost of the product. For low-priced navigation products, the quality of the navigator cannot be guaranteed by the manufacturer in order to reduce the cost. [0003] In order to reduce the price of the vehicle, a considerable number of vehicle audio hosts do not have a navigator, and such car owners need to use an external navigator (for example, a smart phone) for navigation. With the development of smart phones, the screens are getting bigger and bigge...
