浅析乘用车长下坡山路制动试验方法

Analysis of Braking Test Methodology for Passenger Vehicles on Extended Mountain Pass Descents

摘要: 针对山区长下坡工况下因制动系统热衰退引发的交通安全问题，本文提出了一套完整的乘用车长下坡山路制动性能测试方法，用于分析制动系统在高热负荷下的性能表现。其目的是验证制动系统的安全性，确保车辆即使在高热负荷下仍能安全制动，且不会造成制动系统或车辆其他部件的损坏。本文围绕长下坡试验的技术要求、试验内容以及数据分析等方面，详细介绍乘用车长下坡山路制动试验方法。

Abstract: In response to the traffic safety issues caused by the thermal fading of braking systems under the working condition of long downhill slopes in mountainous areas, this paper proposes a complete braking performance testing method for passenger cars on long downhill mountain roads, which is used to analyze the performance of braking systems under high thermal load. The purpose is to verify the safety of the braking system, ensuring that the vehicle can still brake safely even under high thermal load without causing damage to the braking system or other components of the vehicle. This paper elaborates on the braking test method for passenger cars on long downhill mountain roads in terms of technical requirements, test contents and data analysis related to the long downhill test.
