小型汽车一轴、二轴行车制动率检测分析数据

行车制动率是汽车检测时制动性能的综合指标之一，它反映汽车的制动距离、制动减速度及车辆稳定性,是衡量汽车安全性的主要技术指标，其中一轴、二轴行车制动率可以更直观的反应一轴和二轴的制动性能。本数据可以对车辆的情况进行安全性评价，保证了车辆的安全性和检验结果的准确性。本数据可以对车辆整车制动率检测的情况进行安全性评价，为政府监管、消费者购买提供参考和技术支撑。1、一轴行车制动率=（一轴左轮最大行车制动力+一轴右轮最大行车制动力）/（一轴左轮动态轮荷+一轴右轮动态轮荷）/0.98*100%
二轴行车制动率=（二轴左轮最大行车制动力+二轴右轮最大行车制动力）/（二轴左轮动态轮荷+二轴右轮动态轮荷）/0.98*100%
2、根据《GB7258-2017机动车运行安全技术条件》，《GB38900-2020机动车安全技术检验项目和方法》规定，一轴行车制动率合格范围：≥60%，二轴行车制动率合格范围：≥20%。
3、数据应用: 一轴、二轴行车制动率检测结果可以作为车辆安全性评价依据，为监管部门靶向监管提供技术支撑。

Service braking rate is one of the comprehensive indicators for braking performance during vehicle inspection. It reflects the vehicle's braking distance, braking deceleration and vehicle stability, and serves as a core technical indicator for evaluating vehicle safety. The service braking rates of the first and second axles can more directly reflect the braking performance of their respective axles.

This dataset can be used to conduct safety evaluations of vehicle conditions, thereby ensuring vehicle safety and the accuracy of inspection results. It can also perform safety evaluations based on overall vehicle service braking rate test results, providing reference and technical support for government supervision and consumer purchasing decisions.

1. Calculation Formulas:
Service braking rate of the first axle = [(Maximum service braking force of left wheel + Maximum service braking force of right wheel of the first axle) / (Dynamic wheel load of left wheel + Dynamic wheel load of right wheel of the first axle) / 0.98] × 100%
Service braking rate of the second axle = [(Maximum service braking force of left wheel + Maximum service braking force of right wheel of the second axle) / (Dynamic wheel load of left wheel + Dynamic wheel load of right wheel of the second axle) / 0.98] × 100%

2. Qualified Ranges:
Pursuant to "GB 7258-2017 Technical Specifications for Safety of Power-driven Vehicles Operating on Roads" and "GB 38900-2020 Items and Methods for Safety Technology Inspection of Motor Vehicles", the qualified range of service braking rate for the first axle is ≥60%, and that for the second axle is ≥20%.

3. Data Application:
The test results of service braking rates for the first and second axles can be used as a basis for vehicle safety evaluation, providing technical support for targeted supervision by regulatory authorities.
