自動(dòng)擋駕駛注意事項(xiàng)

　　Precautions for automatic transmission driving

　　自動(dòng)擋車(chē)型操作相對(duì)簡(jiǎn)單，但也有一些需要注意的地方。首先要了解各個(gè)擋位的正確使用方法：P 檔是駐車(chē)檔，用于停車(chē)熄火時(shí)，此時(shí)車(chē)輛的驅(qū)動(dòng)輪被鎖止，防止車(chē)輛滑動(dòng)。但要注意，一定要在車(chē)輛完全停穩(wěn)后再掛入 P 檔，否則會(huì)對(duì)變速箱內(nèi)部的鎖止機(jī)構(gòu)造成損傷。比如，有些車(chē)主在車(chē)輛還未完全停穩(wěn)就急于掛入 P 檔，結(jié)果聽(tīng)到 “咯噔” 一聲，這就是鎖止機(jī)構(gòu)受到?jīng)_擊的聲音，長(zhǎng)期這樣操作會(huì)導(dǎo)致鎖止機(jī)構(gòu)損壞，車(chē)輛無(wú)法正常駐車(chē)。

　　Automatic transmission models are relatively easy to operate, but there are also some areas that need to be noted. Firstly, it is necessary to understand the correct usage of each gear: P gear is the parking gear, used for parking and turning off the engine. At this time, the driving wheels of the vehicle are locked to prevent the vehicle from sliding. However, it should be noted that the vehicle must be completely stopped before shifting into P gear, otherwise it may cause damage to the locking mechanism inside the gearbox. For example, some car owners rush to shift into P gear before the vehicle has fully come to a stop, only to hear a "clunk" sound, which is the sound of the locking mechanism being impacted. Long term operation in this way can cause damage to the locking mechanism and prevent the vehicle from parking properly.

　　R 檔是倒車(chē)檔，倒車(chē)時(shí)使用。同樣，要在車(chē)輛停穩(wěn)后才能掛入 R 檔，避免在車(chē)輛還在向前行駛時(shí)強(qiáng)行掛入 R 檔，這會(huì)對(duì)變速箱內(nèi)部的齒輪和離合器造成極大的沖擊，嚴(yán)重時(shí)可能導(dǎo)致變速箱報(bào)廢。

　　R gear is reverse gear, used when reversing. Similarly, it is necessary to shift into R gear only after the vehicle has come to a complete stop, in order to avoid forcibly shifting into R gear while the vehicle is still moving forward. This can cause significant impact on the gears and clutches inside the gearbox, and in severe cases, may result in the gearbox being scrapped.

　　N 檔是空擋，作用類(lèi)似于手動(dòng)擋的空擋，一般用于短暫停車(chē)不熄火時(shí)，如等紅燈時(shí)間較短時(shí)可以使用。但要注意，N 檔不能在車(chē)輛行駛過(guò)程中隨意切換，否則會(huì)導(dǎo)致變速箱油壓不足，無(wú)法正常潤(rùn)滑和散熱，從而損壞變速箱。另外，在 N 檔時(shí)，車(chē)輛失去了發(fā)動(dòng)機(jī)的牽制作用，剎車(chē)距離會(huì)變長(zhǎng)，所以在使用 N 檔時(shí)一定要配合手剎使用，確保車(chē)輛安全。

　　N gear is neutral, similar to a manual neutral gear. It is generally used for brief parking without turning off the engine, such as when waiting for a short red light. However, it should be noted that the N gear cannot be switched arbitrarily during vehicle operation, otherwise it will cause insufficient oil pressure in the transmission, which will prevent normal lubrication and heat dissipation, thereby damaging the transmission. In addition, when in N gear, the vehicle loses the engine's restraining effect, and the braking distance will be longer. Therefore, it is necessary to use the handbrake in conjunction with N gear to ensure vehicle safety.

　　D 檔是前進(jìn)擋，車(chē)輛正常行駛時(shí)使用。在 D 檔模式下，變速箱會(huì)根據(jù)車(chē)速和油門(mén)踏板的程度自動(dòng)選擇合適的擋位。但要避免頻繁換擋，因?yàn)轭l繁換擋會(huì)使變速箱內(nèi)部的離合器和制動(dòng)器頻繁結(jié)合和分離，加速磨損，同時(shí)也會(huì)增加油耗。例如，在城市擁堵路況下，如果頻繁地急加速、急剎車(chē)，變速箱就會(huì)頻繁換擋，不僅會(huì)讓乘坐體驗(yàn)變差，還會(huì)對(duì)變速箱造成損害。

　　D gear is forward gear and is used when the vehicle is driving normally. In D mode, the gearbox will automatically select the appropriate gear based on the vehicle speed and the degree of the accelerator pedal. But frequent gear shifts should be avoided, as they can cause the clutches and brakes inside the gearbox to frequently engage and disengage, accelerating wear and increasing fuel consumption. For example, in congested urban road conditions, frequent rapid acceleration and braking can cause the gearbox to shift gears frequently, which not only deteriorates the riding experience but also damages the gearbox.

　　此外，還要避免長(zhǎng)時(shí)間 D 檔踩剎車(chē)。當(dāng)車(chē)輛掛 D 擋踩剎車(chē)時(shí)，液力變矩器無(wú)法將動(dòng)力完全傳遞給變速箱，這部分能量會(huì)轉(zhuǎn)化為變速箱油的熱能，使變速箱油溫度升高。長(zhǎng)時(shí)間處于這種狀態(tài)，會(huì)加速變速箱油的老化，降低其潤(rùn)滑性能，進(jìn)而影響變速箱的正常工作。如果停車(chē)時(shí)間較長(zhǎng)，比如超過(guò) 30 秒，建議掛入 N 檔并拉手剎，這樣可以減輕變速箱的負(fù)荷，保護(hù)變速箱。

　　In addition, it is necessary to avoid prolonged use of the brakes in D gear. When the vehicle is in D gear and the brake is applied, the hydraulic torque converter cannot fully transmit power to the gearbox, and this energy will be converted into thermal energy of the gearbox oil, causing the temperature of the gearbox oil to rise. Being in this state for a long time will accelerate the aging of the transmission oil, reduce its lubrication performance, and thus affect the normal operation of the transmission. If the parking time is long, such as more than 30 seconds, it is recommended to shift into N gear and pull the handbrake, which can reduce the load on the gearbox and protect it.

　　還有，千萬(wàn)不要用倒擋拖拽車(chē)輛。雖然有些變速箱倒擋變速比大，動(dòng)力看似強(qiáng)大，但實(shí)際上很多自動(dòng)變速箱的倒擋離合器無(wú)論是數(shù)量還是尺寸都比前進(jìn)擋更小，所能承受的扭矩也更小。用倒擋拖拽車(chē)輛很容易損壞倒擋離合器，導(dǎo)致變速箱故障。如果需要救援被困車(chē)輛，應(yīng)盡量使用前進(jìn)擋，或者使用專(zhuān)業(yè)的救援設(shè)備。

　　Also, never drag the vehicle in reverse gear. Although some transmissions have a larger reverse gear ratio and appear powerful, in reality, many automatic transmissions have smaller reverse clutches in terms of quantity and size compared to forward gears, and can withstand less torque. Dragging the vehicle in reverse gear can easily damage the reverse clutch, leading to transmission failure. If it is necessary to rescue a trapped vehicle, try to use forward gear or use professional rescue equipment as much as possible.
