摘要
通过液力缓速器和排气制动外特性曲线,借助simulink建立包括环境因素在内的缓速器和排气制动联合制动的恒速仿真模型,通过PID算法对恒速模型进行控制,仿真实验表明该恒速仿真模型可以有效的保证车辆恒速下坡功能并适应更为复杂的工况。
Through the hydraulic retarder and exhaust brake curve,with the help of simulink to establishthe constant speed simulation modelresearchof cmbining action retarder and exhaust brakeincluding environmental factors,through the PK）algorithm to control the constant speed model.simulation results show that the constant speed simulation model can effectively ensure the constant speed of vehicle downhill function and adapt to more complex condition.
