The invention relates to a long downhill road section vehicle risk state judgment method based on temperature and speed, which is characterized by comprising the following steps of: 1, substituting brake temperature and vehicle speed into a vehicle state judgment model matrix to obtain a vehicle state early warning state grade so as to achieve the purpose of improving the accuracy of long downhill road section vehicle risk state judgment, detecting the temperature of a vehicle brake on the long downhill road section; step 2, determining a temperature risk level to which the current brake temperature belongs; 3, detecting the speed of the vehicle; step 4, determining a speed risk level to which the current vehicle speed belongs; and step 5, giving current vehicle comprehensive risk state judgment according to a judgment model integrating the two influence factors of the temperature risk grade and the speed risk grade.

    基于温度和速度的长下坡路段车辆风险状态判断方法,将制动器温度与车辆速度带入到车辆状态判断模型矩阵中得到车辆状态预警状态等级,以达到提高长下坡路段车辆风险状态判断的准确性的目的,其特征在于,包括以下步骤:步骤1,在长下坡路段检测车辆制动器温度;步骤2,确定当前制动器温度所属的温度风险等级;步骤3,检测车辆速度;步骤4,确定当前车辆速度所属的速度风险等级;步骤5,按照综合了所述温度风险等级和所述速度风险等级这两个影响因素的判断模型给出当前车辆综合风险状态判断。
