【正文】 來推動制動踏板。當這個系統(tǒng)執(zhí)行制動命令、實現(xiàn)自動緊急停車時，迅速產(chǎn)生的制動壓力和車輪制動器的自動預裝可以縮短制動距距。正是由于有來自SBC高壓儲能器更快、更精確的制動脈沖，ESP才能在車輛即將脫距行駛軌道時，及時、平穩(wěn)將其穩(wěn)定下來。在彎道上制動，SBC能提供比傳統(tǒng)制動系統(tǒng)更高的安全性。一方面是擴大控制范圍、增加控制功能；另一方面是采用優(yōu)化控制理論，實施伺服控制和高精度控制。一些智能控制技術(shù)如神經(jīng)網(wǎng)絡(luò)控制技術(shù)是現(xiàn)在比較新的控制技術(shù)，已經(jīng)有人將其應(yīng)用在汽車的制動控制系統(tǒng)中。除技術(shù)外，系統(tǒng)的成本和相關(guān)的法規(guī)是其投入應(yīng)用的關(guān)鍵。通過采用4個比例閥和電力電子控制裝置，KH公司的EBM就能考慮到基本制動、ABS、牽引力控制、巡航控制制動干預等情況，而不需另外增加任何一種附加裝置。要想全面推廣，還有不少問題需要解決：首先是驅(qū)動能源問題。全電制動控制系統(tǒng)面臨的一個難題是制動失效的處理。TTP/C協(xié)議是根據(jù)TDMA制定的。全電制動控制因其巨大的優(yōu)越性，將取代傳統(tǒng)的以液壓為主的傳統(tǒng)制動控制系統(tǒng)。同時需要各種國際及國內(nèi)的相關(guān)法規(guī)的健全，這樣裝備新的制動技術(shù)的汽車就會真正應(yīng)用到汽車的批量生產(chǎn)中。附錄BFuture the automobile brake control system new technology and its the development willIs born from the automobile when, the vehicles braking system is acting the very important role in the vehicles security aspect. In recent years, along with the vehicles technology progress and the automobile moving velocity enhancement, this importance displayed more and more obviouslyAlong with the science and technology development and the automobile industry development, the army vehicle and the military technical development, the vehicles applied the brake to have the new breakthrough, hydraulic brake are in particular apply the brake an after significant innovation following the machinery. Duesenberg the Eight vehicle took the lead to use the passenger vehicle hydraulic brake. Chrysler39。 Because road surface and vehicles state of motion change very big, the many kinds of disturbing effect is bigger, therefore the important question lies in the control the stability, namely system robustness, should maintain under each kind of condition does not lose control. Guards against holds the system request redundant reliability, otherwise can cause the person casualties and the vehicles damage. Therefore, the development robust ABS control system bees the key. Now, the many kinds of Lu stick control system applies ABS in the control logic. Besides the traditional logical threshold method is take pares as the goal, the gain dispatches the PID control, changes the structure control and the fuzzy control is the monly used Lu stick control system, is take slipping rate which at present uses as goal stepless control system. Fuzzily controls the facture is based on the thumb rule control, has nothing to do with with the system model, has very good robust and the control rule flexibility, but adjustment controlled variable quite difficult, does not have the theory to say, basically the method which is depends on tries to collect. However speaking of the majority based on the target value control, the control rule has the certain rule. Moreover, also has uses other control methods, like based on condition spatial gate and linear feedback theory method, fuzzy nerve network control system and so on. Each control method certainly is not alone applies on the automobile, usually is several control methods bines the implementation. If may blur controls and PID unifies, proper attention to both fuzzy control robustness and the PID control high accuracy, can achieve the very good control effect.The observation and control integration brake control system (abbreviation is SBC), is fills the creativity the electron to control the service pattern braking system, will install it in the future while with the vehicle on, will bee enhances an automobile driving secure new milestone. SBC uses the electronic pulse, applies the brake the order the pilot to transmit to a microprocessor in, by its synchronous processing each kind of different sensor signal, and calculates each wheel according to the specific travel condition to be most superior. Thus, when applies the brake when the corner or the wet slippery road surface, SBC can provide pared to a tradition braking system better is initiative security. The SBC system highpressured stored energy and the electrically controlled valve mechanism can guarantee most greatly the brake pressure quickly has the function. Moreover,
