Vehicle path planning method, vehicle path planning system and vehicle navigation apparatus

Abstract

The present invention provides a vehicle path planning method, a vehicle path planning system and a vehicle navigation apparatus so as to solve the problem of no real time traffic condition consideration of the static path planning method. The method comprises: acquiring a starting point coordinate and an end point coordinate of a vehicle; periodically downloading real-time traffic information, wherein the real-time traffic information comprises traffic congestion information and specific event information; and according to the starting point coordinate, the end point coordinate and a real-time traffic information planning path, comparing the currently downloaded real-time traffic information to the last downloaded real-time traffic information to determine whether the real-time traffic condition on the planned path is changed, wherein the path is re-planned according to the current position coordinate, the end point coordinate and the currently-downloaded real-time traffic information if the real-time traffic condition on the planned path is changed. With the present invention, traffic congestion roads can be dynamically evaded so as to provide the fastest driving path for a vehicle driver.

Description

technical field [0001] The present application relates to intelligent transportation technology, in particular to a vehicle route planning method and system and a vehicle navigation device. Background technique [0002] With the rapid development of global positioning system, geographic information system, electronic technology, and computer technology, vehicle navigation system is becoming one of the popular fields of comprehensive technology application, which can prevent traffic jams to the greatest extent and reduce the traffic jams of vehicles on the road. Stay time, and finally realize the optimal distribution of traffic flow on each road section in the network, so that the road network can be used most rationally and effectively. [0003] As the core part of the vehicle navigation system, route planning is required to be able to help vehicle drivers quickly and accurately plan the most optimal path. Therefore, the design and research of path planning methods in vehi...
