Intelligent vehicle lane changing control method based on hazard analysis

Abstract

The invention discloses an intelligent vehicle lane changing control method based on hazard analysis. A sensing unit is used for sensing the driving environment and operation state information, and a decision-making unit judges whether a vehicle needs to change lanes or not according to the collected information; when the current road condition meets the lane changing requirement, the decision-making unit plans a driving path, the planed path is subjected to hazard analysis through simulating calculation, the driving path is adjusted and modified according to hazard analysis results, and the lane changing action can be given up when hazards are too large; after the driving path is determined, a control unit controls the vehicle to achieve the lane changing action; when the current road condition does not meet the lane changing requirement, due to emergency conditions of roads ahead, the vehicle needs to change the lanes emergently; and hazard analysis still needs to be conducted when the vehicle changes the lanes emergently, and the control unit controls the vehicle to act according to analysis results. In the vehicle lane changing process, through the hazard analysis, the lane changing action can be achieved safely and efficiently, and the driving safety and stability of the intelligent vehicle are improved.

Description

technical field [0001] The invention belongs to the field of vehicle intelligent control, in particular to an intelligent vehicle lane change control method based on hazard analysis. Background technique [0002] Although cars have brought great convenience to people's life and travel, with the increase in the number of cars, they have also brought more problems, such as environmental pollution, traffic jams, traffic accidents, etc. Improving driving safety and reducing traffic jams have always been the goals pursued by the industry. The research on smart cars has been paid more and more attention, and how to achieve efficient and safe lane changes has become the focus of research. With the development of computer technology, communication technology, pattern recognition and other technologies, supplemented by correct decision-making and precise control, the active lane change of intelligent vehicles can be realized efficiently and safely. [0003] However, in the existing...
