What are the advantages and disadvantages of automotive electronic control technology
Automobile transmissions are quite important in them. Today, various types of automatic transmissions are available everywhere in the automobile market. Even though there are several automatic transmissions available for the same brand, and even different models of the same car lineup may be fitted with multiple automatic transmissions, different automatic transmissions still have their own advantages and disadvantages. So today, Benshaw Automotive will give you a brief overview. What are the advantages and disadvantages of automotive electronic control technology? Let's take a look.
What are the advantages and disadvantages of automotive electronic control technology:Introduction
Many people should basically know that there are three kinds of automatic transmissions that are often encountered at present, which are AT (Automatic Transmission), CVT (Continuously Variable Transmission) and DCT (Dual Clutch Transmission). Of course, there are two kinds of automatic transmissions:AMT (semi-automatic transmission) and sequential transmission, but there are fewer models.
What are the advantages and disadvantages of automotive electronic control technology:at technology is the most mature transmission.
The most common AT transmission or automatic transmission, I think, refers to this torque converter automatic transmission. As the name suggests, AT uses a torque converter instead of a dry clutch in a traditional manual transmission to transfer engine power to a planetary gear mechanism, which realizes automatic gear shifting through an electronically controlled system. Here it should be clear that AT transmission is not the more gears the better! Because the structure of the planetary gear mechanism is very complex, if you add a gear, it will greatly increase the complexity of the structure, the volume of the transmission and the R&D system. And of course there's the problem that the more complex the structure, the lower the mechanical reliability.
Advantages:
1. Higher power load than CVT
2. Fully proven in the market, so the reliability is the highest year-on-year among automatic transmissions;
3. Matured technology and relatively low R&D cost.
Disadvantages:
1. Complex structure, difficult to repair, high cost of repair;
2. Shift is inflexible, a little &ldquo stupid. , affecting fuel rationality is not good, power output is not smooth enough.
In this case, we should choose it:AT is the best choice to buy an economical family car, save your heart, time and money. Of course, many AT transmissions are quite &ldquostupid. &hellip&hellip
What are the advantages and disadvantages of automotive electronic control technology:CVT is the smoothest and most comfortable transmission.
CVT is known as a Continuously Variable Transmission (CVT), which is a direct translation of the Continuously Variable Transmission (CVT). This transmission has a simpler structure than the traditional AT transmission. Since its transmission structure is different from the gearing of most transmissions, replaced by a combination of bevel gear sets and metal chain belts, it can realize continuous power transmission without breakpoints and keep the engine in ideal working conditions for a long time. As the transmission mechanism is not as rigidly connected as the gear combination, the slippage of the metal chain belt is an inferiority in its genes, directly affecting its &ldquotransmission capacity&rdquoinsufficiency.
Advantages:
1. The smoothest type of transmission and power transmission breakpoint;
2. If the transmission efficiency is the highest in continuous operation at an economic speed, then fuel savings will be achieved;
3. Fewer parts, lighter in weight and smaller in size.
Disadvantages:
1. The service life of the drive belt is shorter than that of the previous year, and the maintenance cost is high;
2. The power load is limited, and it can't be used for high-power engines, and it's not suitable for over-modification or strenuous high-speed driving.
In these cases, you should choose it:CVT is your best choice, as long as it's not a high-powered luxury car in pursuit of driving comfort. Want to play fast? Forget it!
What are the advantages and disadvantages of automobile electronic control technology:DCT perfectly combines the advantages of manual transmission and automatic transmission.
DCT is called Dual Clutch Transmission, also known as double clutch transmission, literally &ldquotransmission with two sets of clutches. Structurally, its transmission mechanism is similar to that of a traditional manual transmission, but because the two sets of clutches work independently and alternately, it is possible to realize a CVT-style power output with almost no breakpoints. There are two branches of this transmission: the dry dual clutch transmission and the wet dual clutch transmission. The difference is that the dry DCT is a semi-closed transmission that requires air-cooling to dissipate heat; in the wet DCT, the two clutch plates are in a sealed tank, and the transmission oil that saturates the clutch plates absorbs heat. Of course, different manufacturers have different names for it. Volkswagen's DSG, for example, is also considered a DCT.
Pros:
1. Highest load carrying capacity because its transmission structure is the same as that of a manual gearbox;
2. Fast gearshift response, with gearshift smoothness only marginally inferior to that of a CVT;
3. High transmission efficiency, with low power loss, and the best fuel economy year-on-year.
Disadvantages:
1. Its high technical requirements, the lowest level of technological maturity compared with other automatic transmissions, greatly reduced reliability, relatively high failure rate;
2. Heat dissipation of dry double-clutching is still an unresolved problem;
3. Wet double-clutching friction at high torque is limited, and therefore to a certain extent insufficient load-carrying capacity .
In this case, we should choose it:Consumers who are looking for sporty performance and driving fun in their cars can consider getting the DCT model. If you need to travel home, you'd better think carefully.
This is the end of today's brief introduction of the car mini-series. These are the advantages and disadvantages of the car electronic control technology briefly introduced by the car small, the car's transmission also plays a vital role. So, in everyone's impression, these three short introductions are basically not OK.I hope the introduction of the automotive small series can solve the problem for you.
