Embodiment Construction
[0059] The specific implementation manners of the path planning method and device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0060] A method for multi-path planning provided by an embodiment of the present invention, such as figure 1 As shown, it specifically includes the following steps:
[0061] S101. According to the obtained start point and end point of the required planning path, determine the candidate path set according to various pre-selected optimization conditions;
[0062] S102. According to the pre-established fuel consumption prediction model, determine the average fuel consumption of each road segment of each route in the candidate route set; the fuel consumption prediction model includes the correspondence between the average fuel consumption of each road segment and the departure time, road grade, real-time road conditions, and driving behavior category relation;

The invention discloses a method and a device for path planning. The method comprises the following steps of, according to a previously established oil consumption prediction model including a corresponding relationship among the average oil consumption of each road segment, departure time, a roadway grade, a real-time road condition and a driving behavior category, determining the average oil consumption of each segment of each path in a candidate path set obtained based on the starting point and the terminal point of a path needing to be planned and an optimal condition; according to the determined average oil consumption of each road segment of each path in the candidate path set and the length of each road segment, determining the total oil consumption needed by each path in the candidate path set; determining the path with the lowest total oil consumption as a final path planning result. As the path with the lowest oil consumption is planned out through the oil consumption prediction model including the corresponding relationship among the average oil consumption of each road segment, the starting time, the road grade, the real-time road condition and the category to which a driving behavior belongs, the path planning carried out based on a relationship among a driving behavior characteristic, the road grade, the real-time road condition and the lowest oil consumption is realized.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for path planning. Background technique [0002] The traffic guidance system provides suggested routes to guide the driver's travel behavior, reduce the driver's anxiety about unknown traffic conditions, and rationally distribute the traffic flow on the entire traffic network, thereby reducing the traffic time consumption in the entire system. Path planning is a prerequisite for the traffic guidance system to provide vehicle navigation functions, and it is the process of helping drivers plan driving paths before or during travel. Therefore, path planning methods are of great significance for improving macroscopic traffic conditions and improving traffic efficiency. . [0003] At present, the methods of path planning mainly include: 1) accurately generate dynamic road condition information for different individuals and different navigation t...
