摘　　要：为了分析行驶在超高速公路曲线路段车辆制动行为的行车风险,综合考虑行驶速度、圆曲线半径、道路超高、制动力对行车风险的影响,建立车辆动力学模型,以侧向加速度和横摆角速度作为行车风险的评价指标,分析了各因素对行车风险的影响。研究结果表明:圆曲线半径对超高速公路曲线路段行车风险有显著影响,影响因素的主次顺序依次为圆曲线半径、速度、制动力、道路超高。对行驶在超高速公路曲线路段的车辆进行风险评估时,需综合考虑车辆的侧向加速度及横摆角速度。研究结果可以为分析超高速公路行驶车辆的安全性提供参考。To analyze the driving risk of vehicle braking behavior on curved sections of superhighways,theimpact of driving speed,radius of circular curves,road superelevation,and braking force on driving risk iscomprehensively considered.The vehicle dynamics model is established,and the lateral acceleration andyaw rate are taken as the evaluation indicators of driving risk.The influence of various factors on drivingrisk is analyzed.The research results indicate that the radius of circular curves has a significant impact onthe driving risk of curve sections on superhighways,with the primary and secondary order of influencingfactors being circular curve radius,speed,braking force,and road superelevation.When conducting riskassessment on vehicles driving on curved sections of highways,it is necessary to comprehensively considerthe lateral acceleration and yaw rate of the vehicle.The research results can provide reference for analyzingthe safety of vehicles driving on superhighways.
