摘要路面附著系數是影響車輛行駛安全性的重要因素,利用輪邊驅動電動汽車驅動力矩可以對路面利用附著系數進行觀測。When the adhesion coefficient is close to the maximum tire - road friction coefficient, the current adhesion coefficient is used as maximum tire - road friction coefficient to control the drive torque
當觀測到? -曲線接近於峰值點時,將該時刻的輪胎利用附著系數作為路面峰值附著系數,並根據識別的路面峰值附著系數進行驅動防滑控制。In the process of emergent brake, relations among brake press, parameters of the entire vehicle and adhesive coefficient between tire and road surface influence the distribution of brake disc friction temperature field greatly
在緊急制動過程中,制動壓力、整車參數以及輪胎與路面間附著系數之間的關系對制動器摩擦溫度場分佈有重要的影響。Based on the confirmation of driving force of lunar rover, we analyze the relationship between adhesion coefficient of road surface and wheel slip. in our research, several types of wheel force model are referenced among them, and we select the polynomial model with exponential function as the wheel force model of the lunar rover
圍繞月球車驅動力的確定,本文分析了路面附著系數與滑轉率的關系,以車輛動力學分析中常用的幾種車輪力模型為基礎,選擇了帶有指數函數的多項式模型作為分析月球車車輪附著力的模型。Detailed contrastive simulation tests of four - phase and self - optimalizing abs control have been made and applying effects of self - optimalizing control are discussed, which establish stable principle foundation for self - optimalizing control applying to realistic abs controller. from the simulation results we can find that : automobiles which install self - optimalizing abs apparatus lock on the any road surface only when the vehicle body velocity and wheel velocity arrive at zero approximately, which is better for improving driving stability under braking. it shows anti - lock ability of self - optimalizing ; slip ratio approximates and surround the desired slip, which shows that this abs system uses fully road surface performance and retains large adhesion and braking performance is good ; braking force regulates with varies of road condition, which realizes road self - identification
通過模擬試驗可以看出:在各種路面上,汽車在安裝了自尋優防抱制動裝置后,在車速、輪速接近為0時才抱死,這對提高汽車制動時的操縱穩定性特別有利,顯示了自尋優避免車輪抱死的能力:滑移率的值基本上一直接近並且圍繞著與路面附著系數相對應的滑移率上下變化,說明了該系統充分利用了路面性能,基本上保持了較大的附著力制動,制動性能較好;制動力隨著路面條件的變化而相應做出調整,實現了路面自動識別的功能。Accordingly a top town vehicle braking model is built with the foundation of vehicle, tire and road adhesion model, meanwhile emb and hb braking system are introduced for contrast and simulation of braking efficiency, the result is prove to be better and higher response speed for the new designed system. additionally, primary anti - rollover analysis for the emb braking system is included in this paper
因此,根據車輛的動力學模型、輪胎動力學模型、路面附著系數模型等建立了綜合的整車制動模型,並把emb制動系統和hb制動系統引入到模型中,進行了制動效能的對比模擬,模擬結果表明emb制動系統具有比傳統制動系統更好的制動效能和更快的響應速度。It is shown in the simulation that sliding mode control can guarantee the stability and robustness while vehicle is braking even if abs operates at the instability region of the adhesion coefficient and wheel slip curve or the surface condition changes, which is better than the pid control and nonlinear pid control
模擬結果顯示,即使在附著系數和滑移率關系曲線的不穩定區域,或是路面狀況發生變化,滑模控制也能保證制動的穩定性和魯棒性,其控制效果優于pid和非線性pid控制效果。分享友人
