Embodiment Construction

[0025] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following paragraphs the invention is described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description.

[0026] Such as figure 1 As shown, the embodiment of the present invention provides a vehicle-mounted device, including:

[0027] The speed obtaining unit 11 is adapted to obtain the average speed of the car within the first predetermined time;

[0028] The path calculation unit 12 is adapted to calculate a new navigation path from the current position to the target point when the average speed is less than the speed threshold, and at least one of the links forming the new navigation path is the same as the link forming the current navigation path. Links are not the same.

[0029] The first predeterm...

Abstract

The invention provides a vehicle-mounted device and an obtaining method of a new navigation route. The vehicle-mounted device comprises a speed obtaining unit and a route calculating unit, wherein the speed obtaining unit is suitable for obtaining average speed of a car in a first schedule time, the route calculating unit is suitable for calculating the new navigation route between a current position and a target position when the average speed is smaller than a speeding threshold, and at least one chain of chains constituting the new navigation route is different with a chain constituting the current navigation route. According to the technical scheme, when a congestion condition occurs, the navigation route is recalculated in a driving mode, a user can obtain the navigation route avoiding the continuous congestion in a short time, car energy consumption is saved, and driving efficiency is improved.

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 vehicle equipment has been developed, such as vehicle navigation system, GPS (Global Positioning System) positioning, TTS (Text to Speech) broadcast, vehicle DVD player, 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 help users f...
