Problems solved by technology

[0004] At present, there are corresponding control methods at home and abroad, but most of them focus on the research of a single individual vehicle, the vehicles are independent of each other, and there is a lack of research on the cooperative behavior of the vehicle during driving; the traffic environment is mostly simplified to a single lane, ignoring the reality Lane changing behavior of vehicles in the environment

Embodiment

[0056] This embodiment is based on the following assumptions:

[0057] 1) This embodiment is in the environment of the Internet of Vehicles, and the penetration rate of Internet-connected autonomous vehicles (CAVs) is 100%. All vehicles can realize vehicle-to-vehicle communication and vehicle-road communication, and the required information can be obtained through vehicle-to-vehicle communication and vehicle-to-vehicle communication. - road communication for transmission;

[0058] 2) The steering behavior of the vehicle at the intersection is not considered;

[0059] 3) The interference of pedestrians and non-motor vehicles is not considered;

[0060] 4) The vehicle can complete the lane changing process instantly and safely;

[0061] 5) Regardless of the delay of vehicle-to-vehicle and vehicle-to-road communication, the speed of information transmission and processing is fast enough compared to the speed of the vehicle, the communication and vehicle control can meet the nee...

Abstract

The invention relates to a single-point intersection vehicle control method for a pure network connection environment. The method specifically comprises the following steps: S1, collecting physical state information of a network connection automatic driving vehicle in an intersection control area; S2, determining an acceleration strategy of a vehicle end and a selection range of a lane strategy; S3, establishing the income of the individual vehicle; S4, establishing an alliance feature function of the vehicle group; S5, establishing an intersection network connection automatic driving vehicle cooperative driving model based on a cooperative game theory; S6, calculating to obtain an optimal driving strategy combination of the vehicle group, and sending the optimal driving strategy combination to a corresponding vehicle end; and S7, enabling the vehicle side to send a control instruction to adjust the driving behavior according to the received optimal driving strategy. Compared with the prior art, the method has the advantages that the comprehensive benefits of vehicle groups in the aspects of safety, efficiency and comfort are effectively improved, and decision suggestions are practically provided for the process that the networked automatic driving vehicles pass through the intersection.

Description

technical field [0001] The invention relates to the research field of road intersection vehicle control technology, in particular to a single-point intersection vehicle control method for a purely networked environment. Background technique [0002] In recent years, the per capita ownership of motor vehicles has increased significantly, and the demand for transportation has increased accordingly. The load on the road traffic system has become increasingly serious, traffic accidents have occurred frequently, vehicle congestion has become prominent, and environmental pollution has become increasingly serious. The occurrence rate of starting, stopping, acceleration and deceleration of vehicles in the intersection area is significantly higher than that in other road network areas, which has a negative impact on the overall continuity of traffic flow operation, resulting in traffic delays. Reasonably controlling the operation of vehicles at intersections, ensuring the safety of v...
