长大下坡车辆连续制动温升模型研究

摘要

公路的长大下坡是事故多发路段，产生事故的原因是多方面的，直接原因是车辆连续制动引发制动器的制动失灵。为提高长大下坡车辆的制动安全性，针对该问题，从长大下坡路段的界定及制动器制动效能“热衰退”的成因出发，对长大下坡车辆连续制动温升模型进行综述，结果表明：制动器制动失灵是多种因素失衡造成的。%Long steep downgrades are typical accident‐prone highway sections .Their causes are various , immediate one of which is brake failure for vehicle continuously braking .To solve this problem of braking safety ,growing up from the definition of downgrade and the causes of heat fading ,the temperature ring models for vehicle continuously braking on long and steep slope are reviewed .The results show that the brake failure is caused by several imbalance factors .
