Embodiment 1

[0049] Such as figure 1 As shown, the embodiment of the present invention provides a method for fleet formation driving, which is mainly applied to fleet travel on straight roads or similar straight road sections on expressways. The method includes:

[0050] In step 101, at least two vehicles form a formation, the first vehicle is driven manually, and the other vehicles follow.

[0051] In the embodiment of the present invention, after the formation of at least two vehicles is completed, the relative position sequence of any two vehicles will not change in the subsequent driving process.

[0052] In step 102, each following vehicle obtains the longitudinal distance between it and the vehicle in front of it and adjacent to it in the fleet, and obtains the longitudinal distance between it and the vehicle adjacent to it in front of it, longitudinal vehicle The distance is the distance between two vehicles in the direction parallel to the lane line.

[0053] In the embodiment of...

Embodiment 2

[0061] Such as figure 2 As shown, the embodiment of the present invention provides a kind of fleet formation driving method, and this method comprises the following steps:

[0062] Step 201, at least two vehicles form formation.

[0063] In the embodiment of the present invention, the formation of at least two vehicles is mainly to determine the following sequence, so after the formation of at least two vehicles is completed, the relative position sequence of any two vehicles will not change.

[0064] Step 202, each following vehicle obtains the longitudinal distance between it and the vehicle in front of it and adjacent to it in the convoy, and obtains the longitudinal distance between it and the vehicle in front of it and adjacent to it, the longitudinal distance between vehicles is The distance between two cars in a direction parallel to the lane line.

[0065] In the embodiment of the present invention, preferably, the forward direction of each vehicle during driving is...

Embodiment 3

[0095] Such as image 3 As shown, the embodiment of the present invention provides a fleet formation driving system, the system applies the fleet formation driving method described in Embodiment 1 or Embodiment 2, which includes: at least two vehicles driving in formation, and the at least two vehicles Each car in the car is equipped with a positioning unit (not shown in the figure), a communication unit (not shown in the figure), a forward vehicle distance detection unit 4, and a rear vehicle distance detection unit (not shown in the figure). ) and an automatic driving control unit (not shown in the figure);

[0096] The positioning part on each vehicle is used for positioning it;

[0097] The communication unit on each vehicle is connected to its positioning unit, and communicates with the communication units of vehicles located in front of and behind it and adjacent to it, and the communication unit on each vehicle is used to communicate The communication unit of the rear...

Abstract

The invention discloses a motorcade formation driving method and system, and belongs to the field of automobiles. The motorcade formation driving method includes the steps that at least two automobiles are organized into a team to drive, the first automobile is driven manually, and the other automobiles are following automobiles; according to the difference of the longitudinal distance between each following automobile and the automobile adjacent to and in front of the following car, each following automobile can judge whether a automobile joins in the motorcade from the position between the following automobile and the automobile adjacent to and in front of the following automobile in the motorcade or not, and each following automobile automatically follows the automobile adjacent to and in front of the following automobile in the motorcade to run according to the judging result, or automatically changes the lane to overtake the automobile joining in the motorcade and automatically follows the automobile adjacent to and in front of the following automobile to run, so that in the driving process of the motorcade, other automobiles except to the first automobile are all automatically driven, the probability of accidents caused by fatigue driving or malfunction of the driver can be lowered, and the safety of the motorcade driving can be improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a driving method and system for fleet formation. Background technique [0002] With the development of science and technology and the improvement of people's living standards, automobiles have become an indispensable means of transportation for human travel. At the same time, the safety of automobiles during driving has also become the focus of human attention. [0003] According to statistics, among the traffic accidents in recent years, traffic accidents caused by driver fatigue driving or operating errors accounted for more than 60% of all traffic accidents, which seriously affected people's lives and property safety. Therefore, there is an urgent need for an automatic driving technology to reduce The probability of traffic accidents caused by driver fatigue or operating errors. Contents of the invention [0004] In order to solve the problem that an automatic driving technology ...
