Abstract

The invention proposes an autonomous cooperative driving decision-making method for an automatic driving vehicle, specifically: the vehicle collects driving state information through an on-board detection system; the vehicle applies fuzzy functions to realize fuzzy processing of driving state information parameters, and the driving state of the vehicle and its neighbor vehicles Estimate; the fuzzified driving state information parameters are used as the input parameters of the fuzzy inference engine, and the fuzzy inference engine infers the vehicle driving mode according to the set fuzzy rule base; the optimal driving mode decision result of the independent vehicle is output by the defuzzification process , to realize autonomous cooperative driving among cluster vehicles. Beneficial effects: through the information detection, calculation and communication capabilities of the self-driving vehicle, through the fuzzification and fuzzy logic reasoning of the vehicle's own driving state parameter set, the autonomous cooperative driving among cluster vehicles can be realized, and the best driving mode can be selected for independent vehicles Provide a reference to improve vehicle driving safety, reduce vehicle travel time, and reduce traffic energy consumption.

Description

technical field [0001] The invention relates to the Internet of Vehicles technology, and in particular to the autonomous cooperative driving technology among self-driving vehicles. Background technique [0002] The Internet of Vehicles (IoV) is the integration of wireless communication technology and transportation network. It is a typical application of the Internet of Things in the field of transportation, and it is the demand for the evolution to autonomous driving. Autonomous driving technology is a traffic intelligence and networking application with high mobility, complex road condition information, and high safety requirements. It is the development trend of road traffic and a necessary process for realizing unmanned driving. The autonomous cooperative driving of the vehicle is essentially a dynamic adjustment process of the driving trajectory according to the road traffic state, the vehicle's own driving state and the neighboring vehicles' driving state. In the Inte...
