Abstract

The invention discloses a navigation method based on time pre-estimation. The method comprises the following steps: a processing module receives target location and current location to generate a navigation route and then sends the navigation route to a road condition acquisition unit; the road condition acquisition unit calculates traffic jam time and sends the traffic jam time to the processing module; and the processing module sends the navigation route and the traffic jam time to an information receiving module. By adding a traffic jam time estimation module into the navigation system, license plate recognition equipment calculates traffic jam time at the road section at current time according to time for a same vehicle passing the congested rood. The system is convenient and fast, provides a navigation map for a driver and is additionally provided with traffic jam time pre-estimation. Thus, the system is convenient for the driver to more visually estimate the arrival time and brings convenience to people's daily work and life.

Description

technical field [0001] The invention belongs to the technical field of car navigation, in particular to a navigation method based on time estimation. Background technique [0002] Geostationary satellites above the Earth were originally used for military and aviation navigation. The U.S. government relaxed restrictions on the use of geostationary satellites in the 1980s, opening up a new world for their subsequent widespread adoption. The subsequent commercial communication satellites have greatly increased the accuracy and coverage of communication satellites. [0003] Ever since there were roads, there have been maps to guide people. However, the maps that serve as people's wayfinding guides are often a source of tension in people's relationships. Because the printed map often cannot keep up with the changes of the street, and is difficult to identify, it will cause the driver to blame the person in the car next to him for not being able to read the map and cannot provi...
