    为了进一步优化汽车电子机械制动系统制动力分配方案,在充分考虑空满载使用频率因素的情况下,以电动汽车制动模型为研究对象,基于SQP算法对电子机械制动系统进行性能优化分析.以理想制动力分配曲线为出发点,建立了目标函数和约束函数,以80km/h初速度制动工况为对象,选取SQP算法进行不等式约束问题研究,从而得到了空满载工况下的同步附着系数、最大制动减速度、制动距离等一系列相关参数,并进行了优化前后的制动力分配和利用附着系数对比实验.实验结果表明,优化后的制动工况较优化前更为稳定,地面附着条件利用更好.In order to further optimize the braking force distribution scheme of the automobile electronic mechanical braking system, the performance of the electronic mechanical brake system is optimized based on the SQP algorithm, taking the electric vehicle braking model as the research object, taking full account of the frequency factor of the empty full load. Taking the ideal braking force distribution curve as the starting point, the objective function and the constraint function are established. Taking the 80km / h initial braking condition as the object, the SQP algorithm is used to study the inequality constraint problem, and the synchronous attachment Coefficient, maximum braking deceleration, braking distance and so on, and the braking force distribution before and after optimization and the comparison of the adhesion coefficient were carried out.The experimental results show that the optimized braking condition is more stable before optimization , Ground conditions attached to the use of better.
