Misunderstanding 1; Automatic transmission car as long as D gear start, has been increasing the accelerator can shift to high speed (gear);

有些駕駛員認(rèn)為只要D擋起步，一直加大油門就可以換到高速擋，殊不知這種做法是錯誤的。

Some drivers think that they can shift to high speed as long as they start in D gear and increase the accelerator all the time, but they don't know that this is wrong.

因為換擋操作應(yīng)是“收油門提前升擋，踩油門提前降擋”。也就是在D擋起步后，保持節(jié)氣門開度5%，加速到40km／h，快松油門，能提高到一個擋位，再加速到75km／h，松油門又能提高一個擋位。降低時按行車車速，稍踩油門，即回到低擋。但必須注意，油門不能踩到底。否則，會強行掛入低速擋，可能造成變速器損壞。

Because the shift operation should be "throttle up in advance, throttle down in advance". That is to say, after starting in D gear, keep the throttle opening at 5%, accelerate to 40km / h, quickly release the throttle, and then increase to a gear. When accelerating to 75KM / h, release the throttle, and then increase to a gear. When lowering, press the driving speed and step on the accelerator slightly to return to the low gear. But it must be noted that the accelerator can not be pressed to the end. Otherwise, it will be forced into low gear, which may cause damage to the transmission.

總之，自動變速器汽車相對于手動變速器汽車而言，省去了離合器踏板，不必頻繁地踩踏板，使汽車駕駛變得簡單、輕松。但若操作不當(dāng)，會人為地增加自動變速器的故障發(fā)生率，降低其使用壽命。正確使用自動變速器，不僅可以避免或減少故障的發(fā)生，還會降低油耗，減少污染。

In a word, compared with the manual transmission vehicle, the automatic transmission vehicle saves the clutch pedal and does not need to step on the pedal frequently, which makes the vehicle driving simple and easy. However, improper operation will artificially increase the failure rate of automatic transmission and reduce its service life. Correct use of automatic transmission can not only avoid or reduce the occurrence of faults, but also reduce fuel consumption and pollution.

誤區(qū)2；自動變速器車輛高速行駛或下坡時，把換擋桿撥在N檔位滑行；

2; When the automatic transmission vehicle is driving at high speed or downhill, set the shift lever to n gear to slide;

有些駕駛員為了節(jié)油，在高速行駛或下坡時，將換擋桿撥到N擋滑行，這很可能燒壞變速器。因為此時變速器輸出軸轉(zhuǎn)速很高，而發(fā)動機怠速運轉(zhuǎn)，變速器油泵供油不足，潤滑狀況惡化，而且對變速器內(nèi)部的多片離合器來說，雖然動力已經(jīng)切斷，但其被動片在車輪帶動下高速運轉(zhuǎn)，發(fā)動機驅(qū)動的主動片轉(zhuǎn)速很低，兩者間隙又很小，容易引起共振和打滑現(xiàn)象，產(chǎn)生不良后果。當(dāng)下長坡確需滑行時，可將換擋桿保持在D擋滑行，但不可使發(fā)動機熄火。

In order to save fuel, some drivers shift the gear lever to n when driving at high speed or downhill, which may burn the transmission. At this time, the speed of the output shaft of the transmission is very high, while the engine is idling, the oil supply of the transmission oil pump is insufficient, and the lubrication condition deteriorates. For the multi plate clutch inside the transmission, although the power has been cut off, its passive plate runs at high speed driven by the wheels, and the speed of the active plate driven by the engine is very low, and the gap between the two is very small, which is easy to cause resonance and slip, There are bad consequences. When it is necessary to slide down the long slope, keep the shift lever at d gear, but do not turn off the engine.

誤區(qū)3；自動變速器車輛坡道停車時不使用駐車制動；

3; Automatic transmission vehicles do not use the parking brake when parking on a ramp;

裝有自動變速器的汽車在坡上停車時，有些駕駛員只是使用P擋，而不使用駐車制動，這樣做極容易引發(fā)事故。因為雖然裝有自動變速器的汽車在P擋位設(shè)有的停車鎖止機構(gòu)一般是很少失效的，但一旦失效就會造成意外事故。因此，在坡道停車時，還是應(yīng)該使用駐車制動器。

When a car with automatic transmission stops on a slope, some drivers only use p gear instead of parking brake, which is very easy to cause accidents. Because although the parking lock mechanism of the car with automatic transmission in P gear is rarely invalid, once it fails, it will cause accidents. Therefore, when parking on a ramp, the parking brake should be used.
