摘要
为了实现电机制动力与机械制动力在车轮上的优化、协调分配,提出一种多参数融合的模糊逻辑复合制动力分配策略。通过构建车辆制动系统动力学模型、模糊与反模糊规则,来确定电机制动力占总制动力需求的分配系数。并在Matlab/Simulink仿真环境下,利用仿真软件Advisor对车辆在三种不同控制策略进行仿真对比,仿真结果表明,本控制策略在满足理想制动力I曲线和ECE制动法规条件下,不但保证了制动的安全性、稳定性,而且能量回收效率较大,从而证明本控制策略设计的可行性。
In order to achieve electric power and mechanical braking mechanism on the wheel optimization,coordinated allocation proposed fuzzy logic composite brake force distribution strategy a multi-parameter integration. By constructing a vehicle braking system dynamics model,fuzzy and antifuzzy rules to determine the total electric power braking mechanism partition coefficient power demand.And in Matlab/Simulink simulation environment,the use of simulation software Advisor vehicles in three different control strategies simulation comparison,simulation results show that this control strategy to meet the ideal braking force curve I ECE braking regulations and conditions,not only to ensure the braking of security,stability,and energy recovery efficiency is large,thus proving the feasibility of the control strategy design.
