大型汽车整车制动率检测分析数据

整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。
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。整车静态轮荷之和=一轴左轮静态轮荷+一轴右轮静态轮荷+二轴左轮静态轮荷+二轴右轮静态轮荷+三轴左轮静态轮荷+三轴右轮静态轮荷+四轴左轮静态轮荷+四轴右轮静态轮荷；
整车最大制动力之和=一轴左轮最大制动力+一轴右轮最大制动力+二轴左轮最大制动力+二轴右轮最大制动力+三轴左轮最大制动力+三轴右轮最大制动力+四轴左轮最大制动力+四轴右轮最大制动力；
整车制动率=整车最大制动力之和/整车静态轮荷之和/0.98*100%；
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，整车制动率合格范围：≥60%

Total vehicle braking rate is one of the comprehensive indicators for braking performance assessment during motor vehicle inspection. It reflects the braking distance, braking deceleration and vehicle stability, and serves as a primary technical indicator for measuring vehicle safety.

This dataset enables safety evaluation of vehicle conditions, ensuring both vehicle safety and the accuracy of inspection results.

Total static wheel load of the entire vehicle = static wheel load of left wheel of Axle 1 + static wheel load of right wheel of Axle 1 + static wheel load of left wheel of Axle 2 + static wheel load of right wheel of Axle 2 + static wheel load of left wheel of Axle 3 + static wheel load of right wheel of Axle 3 + static wheel load of left wheel of Axle 4 + static wheel load of right wheel of Axle 4;

Total maximum braking force of the entire vehicle = maximum braking force of left wheel of Axle 1 + maximum braking force of right wheel of Axle 1 + maximum braking force of left wheel of Axle 2 + maximum braking force of right wheel of Axle 2 + maximum braking force of left wheel of Axle 3 + maximum braking force of right wheel of Axle 3 + maximum braking force of left wheel of Axle 4 + maximum braking force of right wheel of Axle 4;

Total vehicle braking rate = (Total maximum braking force of the entire vehicle / Total static wheel load of the entire vehicle / 0.98) × 100%;

According to GB 7258-2017: Technical Specifications for Safety of Road Vehicles Operation and GB 38900-2020: Items and Methods of Motor Vehicle Safety Technical Inspection, the qualified range of total vehicle braking rate is ≥ 60%.
