Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] A method for obtaining information on future driving conditions under the Internet of Vehicles environment, such as figure 1 As shown, it includes the analysis of the preceding vehicle information, the determination of the target preceding vehicle, the analysis of the change of the traffic flow state and the determination of the information acquisition path, and is characterized in that:

[0019] Such as figure 2 As shown, the first step is to analyze the information of the vehicle in front: first, use the V2V vehicle-to-vehicle communication system and vehicle positioning system in the Internet of Vehicles communication system to determine the distance between the vehicle and the vehicle in front, the direction of the vehicle in front and the path information, and then The obtained vehicle information is analyzed and the analysis results are divided into two categ...

Abstract

The invention provides a future driving condition information acquiring method in a car networking environment, which belongs to the technical field of intelligent car networking. The method comprises the steps of front car information analysis, target front car determination, traffic flow state change analysis and information acquisition route determination. The driving condition information acquiring method is based on car networking communication information. On the basis of fully considering effectiveness and accuracy factors of condition information acquisition, the optimal condition information acquisition route is determined. The acquired driving condition information is closer to actual condition information in the future. The reference and accuracy of the acquired driving condition information as actual condition information in the future are improved.

Description

technical field [0001] The invention provides a method for acquiring future driving condition information in a vehicle networking environment, and belongs to the technical field of intelligent networked vehicles. Background technique [0002] Driving condition is one of the important factors considered in the design of hybrid electric vehicle energy management strategy, and plays a vital role in improving the fuel economy of the vehicle. Accurate and effective acquisition of vehicle future operating condition information and combined with predictive energy management algorithms to achieve real-time optimal control of hybrid power systems has become an effective method for hybrid vehicle intelligent energy management strategies. The method for obtaining the future driving condition of the vehicle in the current prior art: mainly use the GPS system to obtain vehicle information, road information and operation data, or directly receive the information of other vehicles for anal...
