Abstract

The invention provides a vehicle-mounted device and a new navigation route obtaining method. The vehicle-mounted device comprises a guaranteeing unit, a distance obtaining unit and a route calculating unit, wherein the guaranteeing unit is suitable for guaranteeing a problematic chain according to obtained real-time road condition information, and the distance obtaining unit is suitable for obtaining a first distance between current position of a car and the problematic chain on a navigation route. The route calculating unit is suitable for the new navigation route between the current position and a target position based on the real-time road condition information when the first distance is smaller than or equal to a distance threshold, at least one chain of routes constituting the new navigation route is different with the route constituting the current navigation route. By means of the technical scheme, before the problematic chain occurs, the new navigation route different with the current navigation route is obtained timely, navigation efficiency of the vehicle-mounted device is improved, and traffic safety is guaranteed without a manual input method.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a vehicle-mounted device and a method for obtaining a new navigation path. Background technique [0002] With the rapid development of the automobile industry, more and more in-vehicle devices have been developed, such as in-vehicle navigation system, GPS (Global Positioning System) positioning, TTS (Text to Speech) broadcast, in-vehicle DVD player, in-vehicle communication, etc. At present, the application of using GPS (Global Position System, Global Positioning System) to locate the current position of the vehicle is very common. The car navigation device formed by the positioning system combined with the electronic map data is also more and more applied to people's daily life. [0003] The vehicle navigation system of the prior art uses the data provided by GPS, such as latitude and longitude information and heading, to match the road sections in the electronic map data, which can h...
