Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] refer to figure 1 As shown, the hardware configuration of the present invention is introduced according to modules.

[0024] The main control module 1 is composed of an industrial computer 11, and its main function is to analyze and process the collected and fed back information, obtain a lane change plan, and output control commands to the control execution module.

[0025] The information collection module 2 uses a camera 21 to collect lane line information; a millimeter-wave radar 22 to collect the relative speed and distance between surrounding vehicles and the vehicle; a laser radar 23 to detect obstacles.

[0026] The control execution module 3 is composed of a brake controller 31, a steering controller 32, a turn signal controller 33 and an accelerator controller 34, and controls the brakes, the steering wheel, the turn signal and the accelerator of the ...

Abstract

The invention discloses an autonomous lane-changing decision making system for a pilotless automobile. First, through an information collecting module, environment information such as a lane line, an obstacle, speeds of surrounding interactive vehicles, distances between the surrounding interactive vehicles and the pilotless automobile and so on is obtained; the obtained information is transmitted to a main control module; the main control module is used for analyzing the received information, judging whether a lane-changing condition is satisfied or not, carrying out analog computation on the received information to obtain a lane-changing scheme and transmitting the lane-changing scheme to a control executing module; and then a vehicle controller is used for controlling a steering direction, speed and so on of the pilotless automobile according to a decision signal so that the running lane of the pilotless automobile is changed. In the lane-changing process, the information collecting module is required to monitor the environment and the surrounding vehicles in real time; meanwhile, the operation status of the pilotless automobile also needs to be fed back to the main controller in real time so that the pilotless automobile can adjust decision information in time in case of an emergency; therefore, a purpose that the running lane of the pilotless automobile is autonomously changed is safely and effectively realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a decision-making system for an unmanned vehicle to realize autonomous lane change. Background technique [0002] Due to the extensive use of automobiles, although it brings great convenience to people's travel, the problems that follow are also becoming more and more serious, such as causing urban traffic congestion and frequent traffic accidents. Among them, accidents caused by changing lanes account for 4%-10% of the total traffic accidents, and human factors account for 75%. How to improve the safety and reliability of vehicle lane change operation has always been an important topic in the field of traffic safety research. Through accurate environmental information perception, coupled with scientific and reasonable decision-making analysis and stable and reliable control algorithm, the safety of vehicle autonomous lane change is more superior t...
