Long-distance travelling charging planning method for electric vehicle in intelligent traffic

Abstract

The invention provides a long-distance travelling charging planning method for an electric vehicle in intelligent traffic. The long-distance travelling charging planning method comprises a path seeking and charging scheme. During path seeking, a starting point, a destination point and a charging station are viewed as all passing points in a path, two-segment seeking is employed, all probable pathsare proposed, a scheme of reaching a destination place is given out, and after the path is given out, the charging time and the travelling time of each path are solved out. In the charging scheme, the numbers of vehicles in waiting of each charging station is estimated according to a queuing theory, the queuing time and the additional queuing time when the electric vehicle reaches the charging station are estimated, the queuing time that the charging station can be reached is estimated and is combined with the time in the path seeking to obtain the charging time and the traveling time, and areasonable line is planned by a coordination curve method. Optimal path selection can be provided according to a demand without charging, and a path selection scheme and a charging planning scheme also can be provided according to a charging demand.

Description

technical field [0001] The invention relates to an optimal driving planning method for an electric vehicle in intelligent transportation. Background technique [0002] With the intensification of the global financial crisis, the deterioration of the ecological environment, and the depletion of energy and resources, vigorously researching and utilizing electric vehicle-related technologies and promoting industrial development have become a new focus of competition in the world's automobile industry. The United States, Japan, Germany and other major automobile manufacturing powers in the world have joined the ranks of seizing the commanding heights of electric vehicle technology and market. The production and sales of electric vehicles have increased significantly, of which electric passenger vehicles account for more than 90%. The United States, the European Union, China, and Japan are still at the forefront of the global electric vehicle market. General Motors, Ford, and T...
