Abstract

The invention discloses a construction method and device of a vehicle lane changing model, and relates to the technical field of automatic driving. According to the specific scheme, the method comprises the steps that M sets of lane changing data of a vehicle in a manual driving scene are obtained, each set of lane changing data is used for indicating data of the vehicle during lane changing every time, each set of lane changing data comprises values of N kinds of driving attributes, M and N are integers larger than 1, and according to the value of each kind of driving attribute included in each set of lane changing data, N is an integer larger than 1; and determining a first decision-making tree model according to the driving attributes of the vehicle and a preset range corresponding to each driving attribute, and determining a fusion lane changing model according to the first decision-making tree model and a pre-stored second decision-making tree model, the fusion lane changing model being used for lane changing decision of the vehicle in the automatic driving scene. According to the method, the personification degree of automatic driving of the vehicle is improved, and the experience feeling of passengers in the automatic driving process of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and device for constructing a vehicle lane change model. Background technique [0002] Automatic Lane Change (ALC) is one of the core technologies in autonomous driving technology. Through the autonomous lane changing technology, the vehicle can automatically complete the vehicle lane changing and merging behavior without driver intervention, thereby greatly improving the driving efficiency of the vehicle in autonomous driving. The performance of the vehicle’s autonomous lane change largely depends on the pros and cons of the autonomous lane-change strategy. A high-quality autonomous lane-change strategy can “anthropomorphically” generate lane-change intentions at the right time and space, and contribute to the implementation of autonomous lane-change. Prepare. [0003] However, the existing autonomous lane-change strategies are generated based on pre-built l...
