Problems solved by technology
[0004] However, the traditional path planning method generally only navigates according to the distance between the vehicle and the destination. The planned path is unreasonable and cannot meet the needs of users to reach the destination quickly, which brings inconvenience to users and poor experience.

Embodiment Construction
[0022] like figure 1 as well as figure 2 As shown, a vehicle path planning method includes the following steps:
[0023] S110 , the vehicle navigation terminal 110 calculates at least three shorter routes according to the current vehicle location information and the destination information input by the user, and sends the route information of the at least three shorter routes to the route planning server 120 .
[0024] S120, the route planning server 120 obtains the congestion status of each road segment in each shorter route from the third-party real-time traffic server 130 according to the route information of at least three shorter routes, and calculates the congestion status of each shorter route according to the congestion status of each road segment The weight sum of the situation sends the route information of the shorter route corresponding to the minimum weight sum to the car navigation terminal 110 .
[0025] Among them, the weight values of the three congestion...

A vehicle path planning method comprises: a vehicular navigation terminal calculates and obtains at least three relatively short paths according to present vehicle position information and destination information inputted by a subscriber, and sends the three path information to a path planning server; the path planning server acquires the congestion state of each road section of each of the three relatively short paths from a third-party real-time road state server according to the path information of the at least three relatively short paths, calculates the weight sum of each relatively short path in a congestion state according to the congestion state of each road section, and sends the relatively short path information corresponding to the smallest weight sum to the vehicular navigation terminal; the weight values of clearing, slow passage and congestion are 1, 2, and 3 respectively; and the vehicular navigation terminal navigates according to the path information of the relatively short path corresponding to the smallest weight sum. The vehicle path planning system and method can find a relatively quick path for the subscriber; the path planning is reasonable and can meet the requirement for arriving at a destination quickly; the user experience is good.
Description
technical field [0001] The invention relates to path planning technology, in particular to a vehicle path planning method and a path planning system. Background technique [0002] With the continuous development of communication technology and global positioning technology, it provides an increasingly solid technical foundation for navigation technology. People often worry about the complicated road environment when traveling, but with navigation technology, it can bring great convenience to people traveling. [0003] Nowadays, many kinds of car navigation software are gradually popularized in the society. The function of these car navigation software is to provide accurate, effective and fast driving routes for vehicles driving in the road network, and guide the vehicles to reach the destination smoothly. Therefore, a major problem to be solved by vehicle navigation software is path planning. Path planning refers to combining map data to give the optimal path from the sta...
