Eco-driving method based on vehicle-lane coordination technology for vehicle lane-changing behaviors

Abstract

The invention discloses an ecological driving method for vehicle lane changing behaviors based on vehicle-road coordination technology. The method of the invention comprises the following steps: Step1. Verifying the initial vehicle spacing condition: Step 2. Getting a safe driving strategy: when the maximum values of the vehicle acceleration and deceleration and the maximum time of the speed change are set, searching for the acceleration and deceleration values and the speed change time of each vehicle capable of safely driving three vehicles and completing the lane change behavior under eachof the four spacing conditions in the step 1, thereby obtaining a vehicle safe driving disassembly; 3, obtaining an ecological driving strategy: in that solution set of the safe drive strategy obtained in the step 2, searching for a driving method that minimizes the total fuel consumption of three vehicle in the lane changing behavior and the accumulated distance of one kilometer after the lane changing behavior, thereby obtaining an ecological driving strategy of the vehicle lane changing behavior. The invention can minimize the influence and interference of the lane change behavior of the target vehicle on the front and rear vehicles.

Description

Technical field: [0001] The invention relates to an ecological driving method aimed at vehicle lane change behavior based on vehicle-road coordination technology, and belongs to the technical fields of urban road design and traffic safety. Background technique: [0002] With the continuous improvement of people's quality of life, the use of cars has been greatly popularized. By the end of 2017, the number of cars in my country had reached 310 million. While cars facilitate people's travel and life, they inevitably bring many negative effects, such as traffic congestion, noise pollution, energy consumption and exhaust emissions. While aggravating the consumption of non-renewable energy, they also seriously endanger the our living environment. [0003] There are many factors that affect vehicle fuel consumption and exhaust emissions, in addition to the vehicle's own structure and vehicle load. In addition to the frequency of use and long-term maintenance status, it also incl...

Problems solved by technology

However, considering the ecological driving strategy research on vehicle lane-changing behavior is rare, there is no doubt that vehicle lane-changing behavior is a very common driving behavior no matter on urban roads or highways, so how to propose a vehicle lane-changing behavior? A more reasonable and effective ecological driving strategy is of great significance and value for reducing fuel consumption and improving economic efficiency
