In a word , the research results show the feasibility of self - optimalizing control strategy , self - optimalizing abs system is a simple convenient system with better driving stability braking and better adaptability at same time 總之,研究結(jié)果證明了自尋優(yōu)控制用于防抱死剎車系統(tǒng)的可行性,自尋優(yōu)abs系統(tǒng)是一種簡單、方便、具有較好操縱性、制動(dòng)性和較好適應(yīng)性的系統(tǒng)。
2 . according to the principle of successive comprehension and successive measurement of self - optimalizing control theories , the method of step - searching and step - detection has been applied in abs . self - optimalizing strategy on the control of abs is presented in this paper 根據(jù)自尋優(yōu)控制理論連續(xù)理解和連續(xù)測(cè)量的原理,采用步進(jìn)搜索和步進(jìn)探測(cè)的方法,將其應(yīng)用到汽車防抱死制動(dòng)系統(tǒng)中,提出了自尋優(yōu)防抱死制動(dòng)控制策略。
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 通過仿真試驗(yàn)可以看出:在各種路面上,汽車在安裝了自尋優(yōu)防抱制動(dòng)裝置后,在車速、輪速接近為0時(shí)才抱死,這對(duì)提高汽車制動(dòng)時(shí)的操縱穩(wěn)定性特別有利,顯示了自尋優(yōu)避免車輪抱死的能力:滑移率的值基本上一直接近并且圍繞著與路面附著系數(shù)相對(duì)應(yīng)的滑移率上下變化,說明了該系統(tǒng)充分利用了路面性能,基本上保持了較大的附著力制動(dòng),制動(dòng)性能較好;制動(dòng)力隨著路面條件的變化而相應(yīng)做出調(diào)整,實(shí)現(xiàn)了路面自動(dòng)識(shí)別的功能。
This paper makes some systemic and deep researches on abs under the support of shanxi provincial science and technology developing project , i . e . , the development of abs controller with self - intellectual right and give an abs control strategy based on self - optimalizing 論文在陜西省科技攻關(guān)計(jì)劃項(xiàng)目《具有自主知識(shí)產(chǎn)權(quán)的車用防抱死剎車系統(tǒng)( abs )控制器的研發(fā)》的支持下,對(duì)汽車防抱死制動(dòng)系統(tǒng)控制方法進(jìn)行了系統(tǒng)而深入的研究,提出了基于自尋最優(yōu)的防抱死制動(dòng)系統(tǒng)控制策略。
