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.
