摘　　要：线控制动技术(Brake-by-Wire)是纯电动智能汽车的关键技术之一。为了提高智能驾驶汽车制动的安全稳定性,需要针对一款纯电动智能汽车的制动防抱死系统控制逻辑进行研究。在该方案实施前,设置合理的逻辑门限值,通过Stateflow进行仿真实验。基于Simulink搭建了8自由度的车辆动力学模型,对弯道制动工况进行仿真,通过控制车辆的横摆力矩实现车辆的差动控制。通过仿真实验,验证了提出的制动防抱死系统控制逻辑的合理性,对后续的线控制动系统的研发具有指导意义。Brake-by-wire technology is one of the key technologies of pure electric smart cars.In order to improve the safety and stability of automobile braking,it is necessary to study the control logic of the anti-lock braking system of a pure electric smart car.Before the implementation of this program,a reasonable logic threshold is set for simulation experiments.In this paper,a vehicle dynamics model with 8 degrees of freedom is built based on Si mu link to simulate the braking conditions in a curve,and the differential control of the vehicle is realized by controlling the yaw moment of the vehicle.Through simulation experiments,the rationality of the proposed anti-lock braking system control logic is verified,which has guiding significance for the subsequent research and development of brake-by-wire systems.
