纯电动汽车动力性标定方法研究

Research on Dynamic Calibration Method of Pure Electric Vehicle

文章基于某纯电动汽车动力性标定过程,对汽车行驶阻力进行分类分析,对最高车速、加速性能、爬坡性能的设计指标进行分解转化,最后确定电机输出的驱动功率、驱动扭矩,有效保证了车辆的动力性测试结果满足设计指标要求。

Based on the dynamic performance calibration process of a pure electric vehicle, the paper classifies and analyzes the driving resistance of the vehicle, and decomposing and transforming the design indexes of maximum speed, acceleration performance and climbing performance, and finally determining the driving power and driving torque of the motor output, effectively guarantee the power performance of vehicle test results meet the requirements of design index.
