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(mén)就可以換到高速擋，殊不知這種做法是錯(cuò)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?yàn)閾Q擋操作應(yīng)是“收油門(mén)提前升擋，踩油門(mén)提前降擋”。也就是在D擋起步后，保持節(jié)氣門(mén)開(kāi)度5%，加速到40km／h，快松油門(mén)，能提高到一個(gè)擋位，再加速到75km／h，松油門(mén)又能提高一個(gè)擋位。降低時(shí)按行車(chē)車(chē)速，稍踩油門(mén)，即回到低擋。但必須注意，油門(mén)不能踩到底。否則，會(huì)強(qiáng)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(dòng)變速器汽車(chē)相對(duì)于手動(dòng)變速器汽車(chē)而言，省去了離合器踏板，不必頻繁地踩踏板，使汽車(chē)駕駛變得簡(jiǎn)單、輕松。但若操作不當(dāng)，會(huì)人為地增加自動(dòng)變速器的故障發(fā)生率，降低其使用壽命。正確使用自動(dòng)變速器，不僅可以避免或減少故障的發(fā)生，還會(huì)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(dòng)變速器車(chē)輛高速行駛或下坡時(shí)，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(shí)，將換擋桿撥到N擋滑行，這很可能燒壞變速器。因?yàn)榇藭r(shí)變速器輸出軸轉(zhuǎn)速很高，而發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)，變速器油泵供油不足，潤(rùn)滑狀況惡化，而且對(duì)變速器內(nèi)部的多片離合器來(lái)說(shuō)，雖然動(dòng)力已經(jīng)切斷，但其被動(dòng)片在車(chē)輪帶動(dòng)下高速運(yùn)轉(zhuǎn)，發(fā)動(dòng)機(jī)驅(qū)動(dòng)的主動(dòng)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(zhǎng)坡確需滑行時(shí)，可將換擋桿保持在D擋滑行，但不可使發(fā)動(dòng)機(jī)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(dòng)變速器車(chē)輛坡道停車(chē)時(shí)不使用駐車(chē)制動(dòng)；

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

裝有自動(dòng)變速器的汽車(chē)在坡上停車(chē)時(shí)，有些駕駛員只是使用P擋，而不使用駐車(chē)制動(dòng)，這樣做極容易引發(fā)事故。因?yàn)殡m然裝有自動(dòng)變速器的汽車(chē)在P擋位設(shè)有的停車(chē)鎖止機(jī)構(gòu)一般是很少失效的，但一旦失效就會(huì)造成意外事故。因此，在坡道停車(chē)時(shí)，還是應(yīng)該使用駐車(chē)制動(dòng)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.
