随着自动挡车型的普及率越来越高，手动挡反而成了“稀有物种”。与此同时，网上也出现了很多自动变速器的“使用攻略”。但小编发现，攻略中存在很多错误或过时的观点。今天，
济南自动变速箱维修厂家小编就帮大家辨别真伪。
With the increasing popularity of automatic transmission transmission models, manual transmission has become a "rare species". At the same time, many "usage guides" for automatic transmissions have also appeared online. But the editor found that there are many errors or outdated viewpoints in the guide. Today, the editor of Jinan automatic transmission maintenance manufacturer will help everyone distinguish between authenticity.
观点1：启动车辆时需要先接通电源，然后挂入N挡，后再点火起动。否则，启动后换挡杆从P挡换到D挡，中途经过R挡，会给变速器带来一次反向冲击。
Viewpoint 1: When starting the vehicle, it is necessary to first turn on the power, then shift to N gear, and then start the ignition. Otherwise, shifting the gear lever from P to D after startup, passing through R halfway, will cause a reverse impact on the transmission.
实际上，现在的自动变速器早已跨入电控时代，各挡位都是通过电信号控制的，在换挡杆短暂经过R挡时，控制系统并不会向R挡的执行元件发出动作指令，完全不存在“反向冲击”问题。
In fact, modern automatic transmissions have already entered the era of electronic control, with each gear controlled by electrical signals. When the gear lever briefly passes through the R gear, the control system does not issue action commands to the R gear actuator, and there is no problem of "reverse impact" at all.
观点2：停车时需要先拉紧手刹，再把换挡杆推到P挡，否则P挡的锁止齿轮就会承受很大压力，容易过早损坏。
Viewpoint 2: When parking, it is necessary to first tighten the handbrake and then push the gear lever to P gear, otherwise the locking gear of P gear will bear a lot of pressure and be prone to premature damage.
车主完全不必为此担心，因为P挡的驻车锁止齿轮几乎是变速器中“粗壮”的齿轮，就算是坡道停车也能轻松应对。问题是，下次把换挡杆从P挡移出时，可能需要多用点力。
Car owners don't have to worry about this at all, as the parking lock gear in P gear is almost the "sturdy" gear in the transmission, making it easy to handle even when parking on a hill. The problem is that the next time the gear lever is moved out of P gear, more force may be required.
观点3：车辆加速时需要在发动机转速上升至2500～3000r/min时，先轻收油门再踩下油门，这样变速器才能平顺升挡。
Viewpoint 3: When accelerating the vehicle, it is necessary to gently retract the throttle before pressing it when the engine speed rises to 2500-3000r/min, so that the transmission can smoothly upshift.
自动变速器能够根据油门踏板的深浅程度和变化速率等信息，判断驾驶员的意图，并发出与之对应的换挡控制信号。您只需要保持小幅度踩下油门，自动变速器就会在发动机的经济转速区间升挡，兼顾平顺的行驶感受和更低的油耗。
The automatic transmission can determine the driver's intention based on information such as the depth and rate of change of the accelerator pedal, and issue corresponding shift control signals. You only need to keep pressing the accelerator slightly, and the automatic transmission will upshift within the economic speed range of the engine, taking into account the smooth driving experience and lower fuel consumption.
观点4：自动挡车型在加速超车时，需要切换到手动模式，然后手动降一挡再深踩油门，这样才能快速完成超车。
Viewpoint 4: When accelerating to overtake, the automatic transmission model needs to switch to the manual mode, and then manually reduce the gear by one gear, and then step on the accelerator deeply, so as to quickly complete overtaking.
实际上，当您快速深踩油门时，系统就会判断出您正在超车，此时就会控制变速器自动降挡，同时发动机也会增大输出功率，帮您干净利落地完成超车。
In fact, when you quickly and deeply press the accelerator, the system will determine that you are overtaking, and at this time, it will control the transmission to automatically downshift. At the same time, the engine will also increase output power, helping you complete overtaking cleanly.
观点5：在不需要加速的滑行阶段，例如接近路口或红绿灯时，可以将变速器切换到空挡（N挡），降低发动机油耗。
Viewpoint 5: In coasting stages that do not require acceleration, such as approaching intersections or traffic lights, the transmission can be shifted to neutral (N gear) to reduce engine fuel consumption.
这种常见的“节油小妙招”并不适用于自动变速器。自动挡车型在滑行时，发动机就会停止喷油以降低油耗。如果强行换到空挡，发动机为了维持怠速反而需要少量喷油，不仅起不到节油效果，还可能因为变速器内部润滑不良而出现故障。
This common 'fuel saving trick' is not suitable for automatic transmissions. When the automatic transmission transmission vehicle coasts, the engine will stop fuel injection to reduce fuel consumption. If the engine is forcibly shifted to neutral, a small amount of fuel injection is required to maintain idle speed, which not only fails to save fuel, but may also cause malfunctions due to poor internal lubrication of the transmission.
That's all for the use of automatic transmissions. I hope it can be helpful to you. If you have any doubts or needs about this, please come to our website http://www.jnbsx.com consulting service
