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.

    汽車未來(lái)的發(fā)展趨勢(shì)是電動(dòng)化、智能化、共享化以及網(wǎng)聯(lián)化。智能汽車需要感知、控制決策、執(zhí)行等相關(guān)技術(shù)匹配,新型智能線控底盤是智能汽車的關(guān)鍵技術(shù)。線控制動(dòng)(Brake-by-Wire)技術(shù)是智能線控底盤的關(guān)鍵技術(shù),包含傳統(tǒng)制動(dòng)技術(shù),基于動(dòng)力學(xué)、運(yùn)動(dòng)學(xué)、電控等多學(xué)科融合技術(shù),技術(shù)壁壘較高[1]。由于傳統(tǒng)的制動(dòng)系統(tǒng)不能實(shí)現(xiàn)自主制動(dòng),無(wú)法滿足智能電動(dòng)汽車對(duì)制動(dòng)系統(tǒng)的智能電動(dòng)化要求,無(wú)法實(shí)現(xiàn)對(duì)制動(dòng)壓力的快速精確控制,為此本文在傳統(tǒng)制動(dòng)系統(tǒng)上進(jìn)行改造來(lái)滿足智能電動(dòng)汽車對(duì)制動(dòng)系統(tǒng)的需求[2]。
