Comprehensive Evaluation of Intelligent Obstacle Avoidance Function by Changing Lanes of Vehicle Based on an Improved Evaluation Index System

Abstract

In order to make a comprehensive evaluation of the vehicle intelligent obstacle avoidance function by changing lanes, the evaluation index system was improved from the aspects of whether the function is available and how well the function performs. Then, the combination weights of each index were determined by improved G1 method (improved order relation analysis method) and CRITIC method (Criteria Importance Though Intercrieria Correlation method), followed by comprehensive quantitative evaluation by fuzzy comprehensive evaluation method. Finally, the method was applied to the comprehensive evaluation of the vehicle intelligent obstacle avoidance function by changing lanes of three intelligent commercial vehicles. The total scores of the three test vehicles were 92.7, 97.1 and 49.0, and the evaluation grades were excellent, excellent and fail, respectively. The results obtained by this method corresponded to the performance of the vehicles in the test. The results show that the improved evaluation index system is more comprehensive and can determine whether the vehicle has the intelligent obstacle avoidance function and evaluate its performance.
