【正文】 s when control travel automobile may reduce very many difficulties. Applies the brake on the curve, SBC can provide pared to a tradition braking system higher security. Invariable assigns positively is affecting the automobile to change the following aspect to have the original superiority. The recent years, ABS/ASR already became Europe and America and Japan and so on the developed country automobile standard equipment. The vehicles brake control system development mainly is controls technical the development. On the one hand is expands the control area, the increase control function。電子技術(shù)在制動系統(tǒng)中的出現(xiàn),為工程師們帶來了嶄新而前景無限的機(jī)會,它不僅只限于改善汽車的安全性和舒適性。第三是抗干擾處理。采用全電路制動控制系統(tǒng),需要較多的能源,一個盤式制動器大約需要 1kW 的驅(qū)動能量。 經(jīng)過了一百多年的發(fā)展,汽車制動系統(tǒng)的形式已經(jīng)基本固定下來。 ABS 功能的擴(kuò)充除 ASR 外,同時把懸架和轉(zhuǎn)向控制擴(kuò)展進(jìn)來,使 ABS 不僅僅是防抱死系統(tǒng),而成為更綜合的車輛控制系統(tǒng)。試驗表明,在 SBC 的參與下, ESP 可以通過快速、精確的制動脈沖工作更加有效,并能顯著地減少汽車的突然轉(zhuǎn)向。也就是說:在制動過程中,執(zhí)行元件是完全和系統(tǒng)的其余部分?jǐn)嚅_的,它只負(fù)責(zé)記錄發(fā)出的任何制動命令。 SBC 系統(tǒng)的高壓儲能及電控閥裝置能保證最大制動壓力更快產(chǎn)生作用。模糊控制法是基于經(jīng)驗規(guī)則的控制,與系統(tǒng)的模型無關(guān),具有很好的魯棒性和控制規(guī)則的靈活性,但調(diào)整控制參數(shù)比較困難,無理論而言,基本上是靠試湊的方法。另外,由于編制邏輯門限 ABS 有許多局限性,所以近年來在 ABS的基礎(chǔ)上發(fā)展了車輛動力學(xué)控制系統(tǒng) (VDC)。近年來,隨著車輛技術(shù)的進(jìn)步和汽車行駛速度的提高,這種重要性表現(xiàn)得越來越明顯。到 20 世紀(jì) 50 年代,液壓助力 制動器才成為現(xiàn)實。因此,發(fā)展魯棒性 的 ABS 控制系統(tǒng)成為關(guān)鍵。 測控一體化制動控制系統(tǒng) (簡稱為 SBC),是充滿創(chuàng)意的電子控制式制動系統(tǒng),把它安裝在未來的乘用車上,將成為提高汽車駕駛安全性的一個新里程碑。制動主缸將根據(jù)踏板力的大小,在制動路線上形成相應(yīng)的壓力,在機(jī)械和液力相互作用下,通過輪邊制動缸推動制動壓向制動盤。例如,在突然轉(zhuǎn)向的危險情況下, SBC 系統(tǒng)會與電子穩(wěn)定程式 (ESP)相互作用,通過向各個車輪發(fā)出精確的制動脈沖以及 /或者減小發(fā)動機(jī)轉(zhuǎn)速,來保證車輛在突然轉(zhuǎn)向過程中的安全性。 近些年, ABS/ASR 已經(jīng)成為歐美和日本等發(fā)達(dá)國家汽車的標(biāo)準(zhǔn)設(shè)備。因此由 ABS/ASR 進(jìn)一步發(fā)展演變成電子控制制動系統(tǒng) (EBS),這將是控制系統(tǒng)發(fā)展的一個重要的方向。一種完全無油液、完全的電路制動 BBW(BrakeByWire)的開發(fā),使傳統(tǒng)的液壓制動裝置成為歷史。實 現(xiàn)全電制動控制的一個關(guān)鍵技術(shù)是系統(tǒng)失效時的信息交流協(xié)議,如 TTP/C。汽車制動控制技術(shù)的發(fā)展受整個汽車工業(yè)發(fā)展的制約。s, the hydraulic pressure boosts the brake only then to bee the reality. At present, the vehicles guard against hold the brake control system (ABS) to develop into the mature product, and obtained the widespread application on each kind of vehicles, but these products are basic all are add, decelerate the threshold and the reference slipping rate methods design based on the wheel. Method although simple practical, but its debugging quite is difficult, the different vehicles need the different match technology, performs on many different paths to confirm。s EBM can consider basically applies the brake, ABS, the force of traction control, the cruise control applies the brake to intervene and so on the situation, but does not have moreover to increase any kind of addon ponent. The EBM system latent merit is can effectively assign pared to the standard system motion basically, thus causes the stopping distance to reduce 5%. One kind pletely does not have the fat liquor, the plete electric circuit applies the brake BBW (BrakeByWire) the development, causes traditional the hydromatic brake into history. The entire electric brake control system is a brandnew system, has brought the huge transformation for the brake control system, will provide the condition for the future vehicles intelligence control. Must want prehensively to promote, but also has many questions to need to solve: First actuates the energy question. Uses the entire electric circuit brake control system, need more energys, a disc brake probably needs 1kW the actuation energy. At present the vehicles 12V electrical power system could not provide the such big energy, therefore, future the vehicles dynamic system will use the highvoltage, enlarged the energy supply, was allowed satisfiedly to apply the brake the energy request, simultaneously needed to solve the security problem which the high voltage brought. Next is control system expiration processing. The entire electric brake control system faces a difficult problem is brake fade processing. Because does not have the independent initiative spare braking system, therefore needs a backup system to guarantee applies the brake the security, no matter is the ECU ponent failure, the sensor expires or brake itself, the group of lines expires, all can guarantee applies the brake basic performance. Realizes an essential technology which the
