摘要
半主动悬架因阻尼可调,能较好地改善驾驶员的乘坐舒适性。针对商用车驾驶室,提出一种基于模型设计(MBD,Model-Based Design),利用Simulink中的RTW(Real-TimeWorkshop)工具,对磁流变阻尼器式商用车驾驶室半主动悬置电控系统进行设计的方法。通过对模糊自适应PID控制算法进行研究,在Simulink中搭建好控制模型,在模型中对控制策略进行仿真优化,并自动生成适用于S32K144芯片的嵌入式代码,通过相应的开发工具对部分代码进行硬件测试,在Simulink中对模糊自适应PID控制算法进行SIL测试,证实了自动生成嵌入式代码的可用性。利用整车驾驶室平顺性试验,验证了该半主动悬置系统在提升驾驶员舒适度方面的有效性。
The semi-active suspension of the commercial vehicle cab can improve the ride comfort of the driver due to adjustable damping.For the commercial vehicle cab,a method of the magnetorheological damper-semi-active suspension electronic control system design is proposed,which is based on model and uses the RTW(Real-Time Workshop)tool in Simulink.Through the research on the control algorithm,the control model is built in Simulink,the control strategy is simulated and optimized in the model,the embedded code applied to the S32K144 chip is automatically generated,and part of the code is tested by the corresponding development tools.The SIL test of the fuzzy adaptive PID control algorithm is completed in Simulink,which confirms the usability of the automatically generated embedded code.The effectiveness of the semi-active suspension system in improving driver's comfort is verified by the vehicle cab smoothness test.
