自动变速箱与手自一体变速箱的不同点有哪些？

What are the differences between an automatic transmission and a manual automatic transmission?

　　区别：手自一体变速箱是汽车的手动换挡和自动换挡结合在一起的变速方式，而自动变速箱是相对于手动变速箱而出现的一种能够自动根据汽车车速和发动机转速来进行自动换挡操纵的变速装置。

Difference: The manual automatic transmission is a combination of manual and automatic shifting in a car, while the automatic transmission is a transmission device that appears relative to the manual transmission and can automatically shift according to the car speed and engine speed.

Introduction to manual automatic transmission:

　　手自一体变速器就是将汽车的手动换挡和自动换挡结合在一起的变速方式。该变速器结合了自动变速器和手动变速器的优点，最大限度地减少了变速系统的功率损耗。手动挡因为可以根据驾驶员的主观意愿，自由调节挡位及转速，驾驶起来有种畅快的感觉，运动感十足，富有驾驶乐趣。手自一体的手动挡有别于纯手动档的汽车，虽结构中设置有离合器装置，但需要驾驶员操纵，也就是自动离合。手自一体的汽车在用手动挡时，只需拨到手动挡，随着时速的变换，向上或向下调节档位。如果速度跟不上相应的档位，那么档位会自动往下调；如果速度高于所在的档位，则需要手动向上拨。

A manual automatic transmission is a transmission method that combines manual and automatic shifting in a car. This transmission combines the advantages of both automatic and manual transmissions, minimizing power loss in the transmission system. Manual transmission can freely adjust the gear and speed according to the driver's subjective wishes, providing a smooth driving experience with a strong sense of sportiness and enjoyable driving experience. The manual transmission with manual and automatic transmission is different from pure manual transmission cars. Although the structure is equipped with a clutch device, it requires the driver to operate, which is automatic clutch. When using manual transmission in a car that integrates manual and automatic transmission, simply shift to manual mode and adjust the gear up or down as the speed changes. If the speed cannot keep up with the corresponding gear, the gear will automatically adjust downwards; If the speed is higher than the gear you are in, you need to manually shift it up.

2. Introduction to Automatic Transmission:

　　自动变速器的核心在实现自动换挡。所谓自动换挡是指汽车在行驶的过程中，驾驶员按行驶过程的需要操控加速踏板（油门踏板），自动变速器即可根据发动机负荷和汽车的运行工况，自动换入不同挡位工作。

The core of an automatic transmission is to achieve automatic shifting. The so-called automatic shifting refers to the process of driving a car, where the driver controls the accelerator pedal (accelerator pedal) according to the needs of the driving process. The automatic transmission can automatically shift into different gears according to the engine load and the operating conditions of the car.

　　自动变速箱是相对于手动变速箱而出现的一种能够自动根据汽车车速和发动机转速来进行自动换挡操纵的变速装置。目前汽车自动变速箱常见的有四种型式，分别是液力自动变速箱(AT)、机械无级自动变速箱(CVT)、电控机械自动变速箱(AMT)和双离合自动变速箱。

Automatic transmission is a transmission device that appears relative to manual transmission and can automatically shift gears according to the vehicle speed and engine speed. At present, there are four common types of automatic transmissions in automobiles, namely hydraulic automatic transmission (AT), mechanical continuously variable transmission (CVT), electronically controlled mechanical automatic transmission (AMT), and dual clutch automatic transmission.

　　手自一体变速箱工作原理：

Working principle of manual automatic transmission:

　　在结构上，手自一体变速器主要由普通的齿轮箱（和手动变速器一样）、电子控制离合器、自动换挡操纵机构和电子控制部分等组成。电子控制离合器的作用是根据需要自动地使离合器分离、接合或者"吊"离合器，工作时由变速器ECU控制步进电机推动离合器拨叉，使离合器分离或接合。自动换挡操纵机构的作用是根据需要自动地挂入相应的挡位，一般设置两个步进电机，都由变速器ECU来控制。其排挡杆的设置和普通自动变速器相似、没有离合器踏板。该变速器的工作实际上是利用自动控制部分来模拟人工的换挡工作，正常驾驶时和液压自动变速器没有什么区别，只是在停车时，离合器是分离的，所以如果停在坡道上时，一定要踩刹车，否则会溜车。如果使用手动模式，会觉得好象是在驾驶手排挡车一样，动力来得非常直接，还省去了踩离合器的动作，而且不需要一挡一挡地加减挡，可以跳跃加减挡。

Structurally, the manual automatic transmission mainly consists of a regular gearbox (similar to a manual transmission), an electronic control clutch, an automatic shift control mechanism, and an electronic control part. The function of the electronic control clutch is to automatically disengage, engage, or "lift" the clutch as needed. During operation, the transmission ECU controls the stepper motor to push the clutch fork, causing the clutch to disengage or engage. The function of the automatic shift control mechanism is to automatically shift into the corresponding gear as needed. Generally, two stepper motors are set up, both of which are controlled by the transmission ECU. The gear lever setting is similar to that of a regular automatic transmission, without a clutch pedal. The function of this transmission is actually to simulate manual gear shifting using the automatic control part. There is no difference between normal driving and a hydraulic automatic transmission, except that the clutch is disengaged when parking. Therefore, if parking on a slope, be sure to press the brake, otherwise the car will slip. If using manual mode, it feels like driving a manual transmission car. The power is very direct, and there is no need to press the clutch. Moreover, there is no need to shift gears one by one, and you can jump up and down gears.
