Embodiment Construction

[0044] The charging planning method for long-distance operation of electric vehicles in intelligent transportation of the present invention comprises the following steps:

[0045] Step 1: Obtain necessary information such as the remaining power of the electric vehicle (the power must be sufficient for the electric vehicle to reach any charging station), and the power consumed per unit distance.

[0046] Step 2: Assuming that the cellular network is fully covered, read the information of all charging stations in a reasonably planned area, including the charging situation in the station, the waiting situation and the utilization of charging facilities.

[0047] Step 3: Determine whether the remaining power of the electric vehicle can support it to reach the nearest charging station after driving to the destination. If the judgment result is "yes", that is, just drive directly to the destination; if the judgment is "no", then drive to the charging station.

[0048] Step 4: When ...

Abstract

The invention provides a charging planning method for long-distance operation of electric vehicles in intelligent transportation. Includes path finding and charging schemes. In the path finding, the starting point, destination point and charging station are regarded as all passing points in the path, and a two-stage search is adopted to extract all possible paths and give a plan to reach the destination. After the route is given, the charging time and travel time of each route are calculated. In the charging scheme, the number of vehicles waiting for each charging station, the estimated queuing time and the new queuing time when the electric vehicle arrives at the charging station are estimated through queuing theory, and the queuing time at the accessible charging station is estimated, and it is combined with the search path The charging time and travel time are obtained by merging the time in the vehicle, and a reasonable route is planned by the coordination curve method. The present invention can provide optimal route selection when there is no charging demand, and can also provide a route selection scheme and a charging planning scheme when there is 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...
