众所周知，自动变速箱的换挡逻辑十分复杂。除了厂家预设好的换挡逻辑之外，变速箱还有一个十分重要的功能，那就是自我学习功能。这个功能较重要的作用就是学习驾驶者的驾驶习惯，减少变速箱的硬件磨损以及修正硬件偏差。
As we all know, the shift logic of the automatic transmission is very complicated. In addition to the preset shift logic, the gearbox also has a very important function, that is, self learning function. The most important function of this function is to learn drivers' driving habits, reduce the hardware wear of the gearbox and correct the hardware deviation.

不同于手动变速箱，自动变速箱除了会根据路面的情况，节气门开度来调节换挡逻辑之外，其会学习不同驾驶者的习惯来微调换挡逻辑。简单来说，例如某驾驶者习惯大脚油门，变速箱这时候发现换挡时间稍长，在下次做换挡动作时就会增加液力变矩器的压力，反之亦然。这就称为变速箱的自我学习能力。
Unlike the manual transmission, the automatic transmission, in addition to the condition of the road surface, the throttle opening to adjust the shift logic, will learn the habits of different drivers to adjust the shift logic. In a simple way, for example, a driver is accustomed to a big foot, and the gearbox is found to have a long shift at this time, and the pressure of the torque converter will be increased in the next shift, and vice versa. This is called the self - learning ability of the gearbox.
但是变速箱的自我学习能力按照目前来说其实学习的能力并不像我们想象的那么强，目前的技术还是属于粗糙的阶段。较大的用处也就是能学习到这位驾驶员是否喜欢大油门激烈驾驶。我们需要的是变速箱能够根据驾驶者对油门的掌控来进行升降档，例如轻踩油门时我们希望变速箱维持高档位行驶，在深踩油门时能连降两个甚是三个档。但是目前的自动变速箱还尚未完全做到这一点。
But the self - learning ability of the gearbox is not as strong as we have imagined at present, and the current technology is still in the rough stage. The most important thing is to learn whether the pilot likes big throttle driving. What we need is that the gearbox is able to move up and down according to the driver's control over the throttle. For example, we want the gearbox to maintain a high level position when you step on the throttle, and we can drop two or even three gear when you step deep on the accelerator. But the current automatic transmission has not yet fully done this.
变速箱的学习能力也是评判一台变速箱是否“聪明”的标准。车上行驶电脑需要计算的问题大多数都不会太难，但是自学习能力是难度极高的能力。所有的车企特别是变速箱生产厂家都需要做大量的数据积累，大量模拟实验才能调校出一台好的变速箱。
The learning ability of gearbox is also a standard to judge whether a gearbox is "smart". Most of the computing problems on the bus are not too difficult, but self learning ability is very difficult. All vehicle manufacturers, especially gearbox manufacturers, need to do a lot of data accumulation, and a large number of simulation experiments can help to adjust a good gearbox.
