The manual gearbox is not unfamiliar to many people. But when it comes to how to start an ensemble, many people may not know it. Because, as far as I know, many owners of self-contained gearboxes have not really used the manual mode. They use it as an ordinary automatic transmission. In fact, this is a "waste of resources" behavior, this article we talk about how to open the sedans?
â— What is a manual transmission?
The manual transmission, as its name suggests, is a transmission that combines the manual shifting and automatic shifting of the car, and is a kind of automatic transmission. Its greatest feature is that it combines the advantages of both the automatic transmission and the manual transmission, giving the driver the freedom to operate at the same time, allowing the driver to freely choose the right gear and shift timing, which greatly improves the Driving fun.
â— Why do you want to make an automatic transmission?
The automatic gear appeared because people wanted a more comfortable and simple shifting mode, and the emergence of the automatic gearbox was because people found that while the automatic transmission made driving a lot easier, it also deprived People's driving pleasure. Ever since, people have invented the automated manual transmission, which not only satisfies people's comfort and convenience, but also satisfies the driving pleasure that people want.
â— How to use manual gearbox?
The manual gearbox belongs to the "high gear version" of the automatic gearbox, so the method of operation and some precautions are the same as those of the automatic gear model. The only difference is that manual operation can be selected. Currently, there are the following main operating modes in models equipped with manual shift mode:
Integrated type
The so-called integrated type is to integrate the manual mode in the shift lever part of the transmission. As shown in the figure, there are M-block (or S-block), "+", and "-" symbols in the vicinity of the gearbox D block. In the process of driving, if the owner wants to use the manual mode, he only needs to switch the shift lever from D to “M†or “Sâ€, and then perform lift operation according to the situation.
Similarly, there is another hand-integrated gearbox that uses the keys on the shift lever to perform lift operations. As shown in the figure, when the driver hangs the gear into the "S" position (some of them can be directly operated in the D range), it enters the manual mode, and the driver can press the "+" or "-" Perform lift operation.
2. Dial type
Paddle shifts are commonly seen on models that want to focus on the characteristics of the vehicle's motion. The method of use is to put the lever first in manual mode (many models can operate shift paddles at any time during driving). Then use the paddle shift to freely switch the ideal gear when the engine speed is appropriate. Its characteristic is that the efficiency is higher and the shifting process is more direct. The general situation is a downshift on the left and an upshift on the right.
However, there are also differences. For example, many of Porsche's shift paddles are different from the paddle shift paddles shown above. It is possible to perform both upshift and downshift operations on both sides, which is to a large extent more convenient for drivers. operating.
â— When to add or subtract files?
The manual upshift operation and manual gearbox of the manual transmission are a reason to determine the upshift timing at the required rotation speed. If you ignore the engine speed indiscriminate lifting (or not upshift), most models of the brand will be taken out of the protection of the transmission or forced addition and reduction operations.
â— When to use manual shift mode?
1. When you want to drive
As we mentioned earlier, the emergence of automated manual transmissions is largely due to the fact that automatic transmissions deprive people of their driving pleasure. So, if you want to experience the kind of control you want, you need to use the manual shift mode. Of course, this premise is that you must have mastered the relevant driving skills of the manual mode. It should be noted that the hand-in-one mode of many family cars is not fun, regardless of whether the simulation of the shift feel or the implementation of the lift block is not efficient enough, and it is difficult to use.
2. The vehicle has no low gear
Low gear is a safety gear and is mainly used for long uphill/downhill vehicles. When going downhill, a low gear is engaged, and the engine power can be used to control the speed of the brake to ensure that the vehicle speed runs slowly to ensure the safety of driving. When you go uphill, you can use a low gear to use the torque of your car's engine to climb faster. Some models have manual mode gear and no low speed limit gear, so manual mode is needed for long uphill/downhill.
3. Run more curved mountain road
Running a mountain road is fast and fun, and manual mode undoubtedly makes the best choice. Because most of the automatic transmissions do not have a good approach before the mountain roads, it is not always fun and dangerous to bend into the oil and reach the ideal state. When switching to manual mode, you can actively lower the gear in the curve to keep the speed out of the corner quickly. Of course, the premise is that you have mastered the driving skills of the manual transmission, otherwise it may be counterproductive.
4 gearbox tuning is lazy
Some car gearboxes are lazy to tune in and cannot respond quickly to the driver’s intention during driving. For example, when a driver wants to overtake on a high-speed road, most automatic models will choose to lower their speed by themselves. However, depending on the depth of the throttle, some may drop several gears, and some may only lower a gear or simply do not lower the gear. High-speed overtaking If you encounter a gearbox that is very lazy to adjust, you may want to switch to the manual mode. By manually lowering the gear, the driver can quickly increase the speed with the low gear's high torque and complete the overtaking action more quickly.
Summary: We also know that most automatic transmission owners have forgotten the pureness of the manual mode. With the increasing tightness of the automatic gearbox shift logic design, the frequency of manual mode use is getting lower and lower. But the same reason, the penetration rate of the manual transmission in the market is also very high, and now the efficiency and feel of the manual shifting of the car are constantly improving. A gearbox, two kinds of driving mood, can actually develop the performance of the manual mode when conditions and interests are interested, so that the automatic transmission car can be opened more freely.
