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。

Abstract: 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 Simulink 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.

    汽车未来的发展趋势是电动化、智能化、共享化以及网联化。智能汽车需要感知、控制决策、执行等相关技术匹配,新型智能线控底盘是智能汽车的关键技术。线控制动(Brake-by-Wire)技术是智能线控底盘的关键技术,包含传统制动技术,基于动力学、运动学、电控等多学科融合技术,技术壁垒较高[1]。由于传统的制动系统不能实现自主制动,无法满足智能电动汽车对制动系统的智能电动化要求,无法实现对制动压力的快速精确控制,为此本文在传统制动系统上进行改造来满足智能电动汽车对制动系统的需求[2]
