摘要
现阶段,汽车已是人们出行的重要交通工具,而汽车驾驶安全与汽车的电子机械制动系统密切相关。汽车制动系统其主要对停车过程中的速度加以控制,降低坡道对汽车停止的影响,可以有效确保驾驶员的行车安全。由此可见,在设计、保养汽车过程中需要全面兼顾汽车制动元件性能的设计、优化与养护。本文通过SQP算法以及电动汽车制动模型分析汽车电子机械系统性能优化设计。利用SQP算法对理想状态下的制动力分配曲线进行研究,从而构建语速函数、目标函数等。同时,利用90km/h初始速度开展研究,进而获取相对应的同步附着系数等数据。仿真实验结果表明,优化设计后的汽车电子机械制动系统较为稳定,其他条件也有所改善。
At present,the automobile is an important means of transportation for people,and the driving safety of the automobile is closely related to the electronic mechanical braking system of the automobile. The automobile brake system mainly controls the speed in the parking process to reduce the impact of the ramp on the vehicle stop,which can effectively ensure the driving safety of the driver. From this,it can be seen that the design,optimization and maintenance of the performance of the automotive brake elements need to be fully taken into account in the design and maintenance of the automobile. This paper analyzes the optimal design of automotive electronic mechanical system performance through SQP algorithm and electric vehicle braking model. The SQP algorithm is used to study the braking force distribution curve in an ideal state,so as to construct a speech rate function,an objective function,and the like. At the same time,the study was conducted using the initial speed of 90 km/h,and corresponding data such as the synchronous adhesion coefficient were obtained. The simulation results show that the optimized design of the automotive electronic mechanical brake system is relatively stable,and other conditions have also been improved.
