A method for centralized optimization and coordination of intelligent networked vehicles in the entrance area

Abstract

The invention discloses a method for centralized optimization and coordination of intelligent networked vehicles in the entrance area, including: 1) a centralized controller set in the entrance area receives the state information of the vehicles within the communication range, and sets a unique number for the vehicles; 2) ) According to the state information of the above vehicles, the global optimization solution is carried out to obtain the optimal acceleration of each vehicle in the entrance area at each moment, and the optimal acceleration information is transmitted to each vehicle respectively; 3) Each vehicle according to The received optimal acceleration information performs corresponding acceleration / deceleration control, and transmits its own status information to the centralized controller in real time; returns to step 2) until the vehicle drives out of the entrance area, and disconnects the communication with the centralized controller. The method of the invention aims at the high efficiency, energy saving and comfort of the vehicle, optimizes and solves the trajectories of all the vehicles on the main road and the ramp, so as to realize the coordination of each vehicle passing through the entrance area.

Description

technical field [0001] The invention belongs to the technical field of intelligent networked traffic systems, and in particular relates to a method for centralized optimization and coordination of intelligent networked vehicles in an entrance area. Background technique [0002] With the rapid development of vehicle electronics and computer technology, vehicle intelligence and networking have become one of the main directions of road traffic development. With the continuous growth of global car ownership, problems such as urban road congestion, frequent accidents and energy shortages have hindered the further development of road traffic. Therefore, it is necessary to build an intelligent transportation system by realizing the intelligence and networking of vehicles to improve vehicle traffic efficiency and fuel economy. For the ramp entrance area, which is an important part of urban roads, it is necessary to propose some intelligent and network-based integration coordination...

Problems solved by technology

However, since the accuracy of the driver's judgment and decision-making through visual inspection is heavily dependent on the driver's driving skills and proficiency, it is easy to decelerate, accelerate rapidly or collide with vehicles on the main road during the merge process. and so on

However, in the existing coordinated importing methods of intelligent networked vehicles at the entrance, a part of the Markov decision framework is used to estimate the state of the ramp vehicle. , it is impossible to achieve the global optimum of all vehicles in the entire inlet area, and its decision-making effect is heavily dependent on the quality of parameter training; part of it is through inter-vehicle communication to avoid collisions between vehicles, but the efficiency and energy saving of all vehicles through the inlet area sex is not considered
