摘要: 線控制動技術(shù)(Brake-by-Wire)是純電動智能汽車的關(guān)鍵技術(shù)之一。為了提高智能駕駛汽車制動的安全穩(wěn)定性,需要針對一款純電動智能汽車的制動防抱死系統(tǒng)控制邏輯進行研究。在該方案實施前,設(shè)置合理的邏輯門限值,通過Stateflow進行仿真實驗?;赟imulink搭建了8自由度的車輛動力學(xué)模型,對彎道制動工況進行仿真,通過控制車輛的橫擺力矩實現(xiàn)車輛的差動控制。通過仿真實驗,驗證了提出的制動防抱死系統(tǒng)控制邏輯的合理性,對后續(xù)的線控制動系統(tǒng)的研發(fā)具有指導(dǎo)意義。

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.
Key words : pure electric smart car;anti-lock brake system;corner braking;logic threshold control;differential control

    汽車未來的發(fā)展趨勢是電動化、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(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)制動技術(shù),基于動力學(xué)、運動學(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)的制動系統(tǒng)不能實現(xiàn)自主制動,無法滿足智能電動汽車對制動系統(tǒng)的智能電動化要求,無法實現(xiàn)對制動壓力的快速精確控制,為此本文在傳統(tǒng)制動系統(tǒng)上進行改造來滿足智能電動汽車對制動系統(tǒng)的需求[2]。
