The invention discloses a pure electric vehicle load estimation method based on an intelligent optimization algorithm, and the method comprises the steps: carrying out the reasoning of a vehicle dynamic balance equation of the adjacent states of a vehicle, and obtaining two specific driving states with the relatively accurate estimation mass and the relatively stable vehicle state through a data analysis method; according to the method, boundary parameters of two estimation states are optimized through an intelligent optimization algorithm, the vehicle load is estimated in combination with the vehicle speed, acceleration and total driving torque information, and the technical problems that a traditional estimation method is high in model complexity, low in algorithm convergence speed and the like can be effectively solved.

    本发明公开了一种基于智能优化算法的纯电动汽车载荷预估方法,通过对车辆相邻状态的车辆动力学平衡方程推理,然后利用数据分析方法得到两种预估质量相对准确,车辆状态相对稳定的特定行车状态,采用智能优化算法对两种预估状态的边界参数进行优化,结合车辆速度、加速度、总驱动转矩信息对车辆载荷进行预估,所提出的方法能够有效解决传统预估方法模型复杂度高、算法收敛速慢等技术问题。
