specific Embodiment approach 1

[0024] Specific implementation manner 1: The specific process of the vehicle lane changing method considering the overlapping area of ​​the multi-vehicle interaction area in this embodiment is:

[0025] Step 1: Set i car as the target vehicle, i-1 car as the front car in the current lane of the target vehicle, i+1 car as the rear car in the current lane of the target vehicle, and j-1 car as the target vehicle on the left side of the target lane The vehicle ahead of j is the rear vehicle on the left side of the target lane in the forward direction of the target vehicle;

[0026] Step 2: Define the driving restriction area and the multi-vehicle interaction area where the vehicle is traveling, where the multi-vehicle is greater than or equal to 2 vehicles;

[0027] Step 3: Calibrate the shape parameters of the restricted area a 1 , B 1 The shape parameter of the interaction area with multiple vehicles a 2 , B 2 ;

[0028] Step 4: Use Matlab software to determine the overlap area between ...

specific Embodiment approach 2

[0033] Specific embodiment two: this embodiment is different from specific embodiment one in that in the second step, the driving restriction area and the multi-vehicle interaction area for vehicles are defined. The multi-vehicle is 2 or more vehicles. The specific process is:

[0034] Such as figure 1 As shown, the vehicle ahead in the current lane of the target vehicle is the reference system, the geometric center of the target vehicle is the coordinate origin, the forward direction of the vehicle is the positive direction of the x-axis, and the direction perpendicular to the forward direction of the vehicle and pointing to the left of the forward direction of the vehicle is the y-axis In the positive direction, establish a two-dimensional plane rectangular coordinate system;

[0035] The driving restriction area and the multi-vehicle interaction area of ​​the vehicle are respectively determined by figure 1 (1) and (2) shown in the ellipse closed curve (dotted line part).

[0036] ...

specific Embodiment approach 3

[0042] Specific embodiment three: This embodiment is different from specific embodiment one or two in that in the step three, the shape parameter a of the vehicle travel restriction area is calibrated separately 1 , B 1 The shape parameter of the interaction area with multiple vehicles a 2 , B 2 , The specific process is:

[0043] Strictly avoiding overlapping of driving restriction areas during vehicle driving is the basic condition for multi-vehicle collisions not to occur. This can ensure that the distance between vehicles is not too small. The overlap of interactive areas between multiple vehicles will produce interactive effects and games, which will affect their respective speeds. And driving decisions. The shape parameters of the constrained area and the interaction area directly affect the degree of interaction between multiple vehicles. The following four shape parameters are taken in conjunction with Figure 2:

[0044] The shape parameter of the driving restriction area a...

Abstract

A vehicle lane changing method in consideration of the overlapping area of the interaction areas of multiple vehicles is provided. The invention relates to a vehicle lane changing method for a multi-vehicle interaction operation rule in the lane changing process of vehicles. The method comprises the step of: setting the i-th vehicle as a target vehicle, setting (i-1)-th vehicle as a vehicle aheadof the target vehicle in a current lane, setting (i+1)-th vehicle as a vehicle behind the target vehicle in the current lane, setting the (j-1)th vehicle as a vehicle ahead of the target vehicle in aleft target lane in the driving direction of the target vehicle, and setting the j-th vehicle as a vehicle behind the target vehicle in the left target lane in the driving direction of the target vehicle; defining a driving constraint area and the interaction areas of multiple vehicles; calibrating a shape parameter; determining the overlapping area of the interaction area of the target vehicle and the surrounding vehicles; when the interaction areas of the multiple vehicles do not overlap, determining that the vehicles do not interact and using a free lane changing mode; when the interactionareas of the multiple vehicles overlap, determining that the vehicles interact with each other, and using a interactive lane changing mode. The method is used in the field of road traffic safety.

Description

Technical field [0001] The invention belongs to the technical field of road traffic safety active prevention and control and traffic simulation, and specifically relates to a vehicle lane changing method. Background technique [0002] In recent years, the number of vehicles in my country has continued to increase, and road traffic accidents have occurred frequently. Among them, the number of road traffic accidents caused by vehicle changing lanes accounts for a relatively high proportion. According to statistics, the number of road traffic accidents caused by vehicle changing lanes accounted for about the total number of accidents. 27%. During the lane changing process, the interaction between the lane changing vehicle and the surrounding vehicles has a greater impact on the stability of the traffic flow. [0003] Patent CN109035862A discloses a multi-vehicle coordinated lane change control method based on vehicle-to-vehicle communication. The method relies on information transmiss...
