眾所周知，自動(dòng)變速箱的換擋邏輯十分復(fù)雜。除了廠家預(yù)設(shè)好的換擋邏輯之外，變速箱還有一個(gè)十分重要的功能，那就是自我學(xué)習(xí)功能。這個(gè)功能較重要的作用就是學(xué)習(xí)駕駛者的駕駛習(xí)慣，減少變速箱的硬件磨損以及修正硬件偏差。
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.
濟(jì)南自動(dòng)變速箱維修
不同于手動(dòng)變速箱，自動(dòng)變速箱除了會(huì)根據(jù)路面的情況，節(jié)氣門開度來(lái)調(diào)節(jié)換擋邏輯之外，其會(huì)學(xué)習(xí)不同駕駛者的習(xí)慣來(lái)微調(diào)換擋邏輯。簡(jiǎn)單來(lái)說(shuō)，例如某駕駛者習(xí)慣大腳油門，變速箱這時(shí)候發(fā)現(xiàn)換擋時(shí)間稍長(zhǎng)，在下次做換擋動(dòng)作時(shí)就會(huì)增加液力變矩器的壓力，反之亦然。這就稱為變速箱的自我學(xué)習(xí)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.
但是變速箱的自我學(xué)習(xí)能力按照目前來(lái)說(shuō)其實(shí)學(xué)習(xí)的能力并不像我們想象的那么強(qiáng)，目前的技術(shù)還是屬于粗糙的階段。較大的用處也就是能學(xué)習(xí)到這位駕駛員是否喜歡大油門激烈駕駛。我們需要的是變速箱能夠根據(jù)駕駛者對(duì)油門的掌控來(lái)進(jìn)行升降檔，例如輕踩油門時(shí)我們希望變速箱維持高檔位行駛，在深踩油門時(shí)能連降兩個(gè)甚至是三個(gè)檔。但是目前的自動(dòng)變速箱還尚未完全做到這一點(diǎn)。
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.
變速箱的學(xué)習(xí)能力也是評(píng)判一臺(tái)變速箱是否“聰明”的標(biāo)準(zhǔn)。車上行駛電腦需要計(jì)算的問(wèn)題大多數(shù)都不會(huì)太難，但是自學(xué)習(xí)能力是難度極高的能力。所有的車企特別是變速箱生產(chǎn)廠家都需要做大量的數(shù)據(jù)積累，大量模擬實(shí)驗(yàn)才能調(diào)校出一臺(tái)好的變速箱。
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.
