Analysis of factors affecting vehicle skidding during braking on curved sections of superhighways

Abstract

In order to analyze the driving risk of vehicle braking behavior on curved sections of super highways, the driving speed, circular curve radius, and road super.The influence of height and braking force on driving risk is established. The vehicle dynamics model is established, and the lateral acceleration and yaw rate are used as evaluation indicators of driving risk.The influence of various factors on driving risk was analyzed. The results show that the radius of circular curve has a significant impact on the driving risk of curved sections of super highways.The order of priority of the factors is circular curve radius, speed, braking force, and road superelevation. When conducting risk assessment on vehicles traveling on curved sections of superhighways.The lateral acceleration and yaw rate of the vehicle need to be considered comprehensively. The research results can provide a reference for analyzing the safety of vehicles traveling on super highways
