有關ABS問題

點解要等ABS盞燈熄左至可以撻車?(我用Mazda 3)

仲有何謂ABS?解釋一下???

    當擰到ON時 , 錶板上各燈應該會亮着 , 然後逐一熄滅(包括ABS) , 當引擎點火後 , 如果引擎有問題 , 相關嘅燈就會著 ,

    ABS全名為防鎖死剎車系統 , 其工作原理 :

    依靠裝在各車輪上高靈敏度的車輪轉速傳感器以及車身上的車速傳感器,通過計算機控制。緊急制動時,一旦發現某個車輪抱死,計算機立即指令壓力調節器使該輪的制動分泵泄(減)壓,使車輪恢復轉動。ABS的工作過程實際上是抱死-松開-抱死-松開的循環工作過程,使車輛始終處于臨界抱死的間隙滾動狀態,有效地克服緊急制動時的跑偏、側滑、甩尾,防止車身失控等情況的發生。 死煞車

    1.自動瞬間反覆剎車

    剎車制動力在車輪打滑前最大,一旦車子打滑後,制動方便會驟減。緊急剎車時,沒有注意到打滑的發生,而緊踩剎車不放。ABS便是預防車子因剎車時輪胎鎖死打滑而設計,特別是在易滑路面最能發揮效果。

    ABS是由能夠控制剎車控制系統、油壓的調節裝置,以及能夠檢知車輪速度的感知器所構成。當駕駛者用力踩下剎車踏板時,ABS系統能維持最大的制動力,反覆剎車作用,可防止輪胎打滑,增加操控性。瞬間反援用力踩剎車踏板,以人類最大的極限而論,只能一秒鐘踩二至四回,而最近開發的ABS系統能夠達到一秒錢五50回,非常實用。

    2.ABS系統在結冰路面無效

    ABS系統在高速行駛中確實能夠達到防止車輪銷死打滑的效果,使車子能夠繼續操控。而四輪碟剎更能確保維持高制動力及最短的剎車距離。 雖然ABS有非常好的性能,但是超速過多或是濫用開車技巧,仍可能失效,畢竟此系統只是輔助您愛車在緊急剎車時不至於失控的輔助裝置,因此不宜太過依賴。要深刻瞭解ABS的實力,建議您不妨找機會試試急踩剎車,親自體驗看看。但切記在配備ABS的車上,不可點踩剎車。

    可能許多人對對于ABS的原理略知一二,但絕大多數車主卻不知道如何使用正確地使用ABS。ABS使用是否得當,直接關系到行車安全。

    1.ABS制動時,制動分泵的高速收放動作會使高壓的制動液被頻繁擠壓,產生較大的聲音,制動踏板也會有抖動和頂腳現象。駕駛時不要被這種現象困擾,在緊急情況下使用ABS制動要毫不猶豫,用力直接把剎車踩到底,不能放松。

    2.由于ABS緊急制動時車輪不抱死,前輪仍有導向作用,Driver可以邊剎車邊打方向進行緊急避險。

    3.ABS系統對制動液的要求非常之高,因此添加制動液應嚴格按照使用說明書上的要求,一般禁止摻雜不同型號的制動液。建議一年更換一次相同型號的制動液。

    4.ABS車輪傳感器及齒圈均安裝在各個車輪上,要經常保持傳感器探頭及齒圈的清潔,防止有泥污、油污特別是磁鐵性物質沾附在其表面,從而導致傳感器失效或輸給計算機的信號錯誤而影響ABS系統的正常工作。

    5.裝有ABS系統的車輛應嚴格遵循規定的輪胎氣壓標准,同時要保持同軸輪胎氣壓的均衡,嚴禁使用不同規格的輪胎。此外,要注意檢查輪速傳感器探與齒圈之間的間隙,輪子軸承軸向間隙過大會直接影響ABS的正常工作。

    6.在行車中Driver應注意儀表盤上的ABS指示燈的情況。如發現閃爍或發亮不滅,說明ABS系統已脫離工作狀態。此時制動系統已回歸常規制動工作界面,車子是可以繼續行駛的,但已不具ABS功能,建議盡快檢修

    1.Wai!照計應該係撻車嘅同時,錶板上各燈号應該要亮着,確保架車係正常;當聽到engine點火聲後,無關係既燈号就會自動熄滅.

    1st, you don't have to wait for the ABS indicator to go off before firing up the engine. No car will require that. The ABS indicator comes on when you start the car or the engine is a step the computer in the car take to make sure the component are functioning. If it stays on, that means your ABS module or component is having issue.

    ABS stands for Anti-Lock Braking System. ABS is a safety device implemented to automobiles in the late 70s/early 80s. The tires are the only contact patches the driver have between the car and the road. You only have traction if the tires are rolling. On slippery surface or when the car tried to be stopped from high velocity (large velocity change), the tires' traction may break lose and if the driver keep his foot on the brake pedal the tire/wheel will be locked (wheels and tires don't rotate/roll while the car still moving). Some skillful drivers will pump the brakes, to "unlock" the wheel and tires and let the tires roll and gain traction again and then step on the brake again, and repeat if the tires lock again. However, not all of us are skillful drivers, so the ABS device will actually monitor the rotational speed of individual wheels, and when wheel lock is sensed (rotation speed from one or multiple wheels are different than the other wheels, or different from the vehicle's speed), the ECU or computer of the car will automatically release and pressure the brake. All the driver has to do when trying to stop the car in emergency on slippery condition with ABS is to slam on the brake and turn to the desired direction he wants to. Without ABS, the driver has to pump the brake, detect slippery by himself, and do turn and counter turn of the wheel.
