Abstract

The invention discloses an automobile-mounted navigation system and a method, and relates to the technical field of automobile navigation. The automobile-mounted navigation system comprises an information input device, a GPS (Global Position System) module, a wireless communication module, an automobile-mounted controller and a display device, wherein the automobile-mounted controller determines a path strategy; the path strategy is that whether the length of a first shortest path exceeds a first distance threshold is judged; if so, the first shortest path, and N paths avoiding a traffic jam intersection with a shortest path between the intersection and a current position less than a second distance threshold, and avoiding a disaster weather site with a shortest path between the disaster weather site and a current position less than a third distance threshold are provided for a driver to select; and if not, navigation is performed according to a normal navigation mode. With the adoption of the design, traffic jam and weather situations of short distance and long distance travels can be considered discriminatively, and an optimal path can be determined.

Description

technical field [0001] The invention relates to the technical field of car navigation, in particular to a car navigation system and method. Background technique [0002] The car navigation system can realize digital intelligent navigation for field survey and travel. Under the existing technical conditions, people can not only select the car navigation system as an optional configuration when buying a new car, but also install the device on existing cars. [0003] The existing car navigation system has the functions of updating maps in time, increasing hardware processing speed, optimizing path algorithm, adjusting menu options and searching classification. In recent years, as consumers gradually recognize car navigation systems, the market demand for car navigation systems continues to expand. [0004] Weather conditions, unforeseen traffic accidents, and traffic jams all have an impact on car travel. These situations have different impacts on the path planning of proces...
