If you just simply compare the difficulty of driving operation, then the automatic transmission car is naturally recognized to be lower than the manual transmission car, but don’t think that you can get an automatic transmission car without a certain degree of understanding. You can open it with your hands, and there are also many gear marks on the automatic gearbox. What do the P, R, N, D, S, and L on the automatic gear mean? The old driver answered this one by one, and said: A formula will teach you!
Among the specific gearboxes mentioned above, the most basic and common are the four P, R, N, D, so in order, let’s talk about the P gear first. . In fact, P here means the initials of PARKING, which means parking. P block corresponds to the parking block of the vehicle. After cutting in, the mechanical locking mechanism in the gearbox can be used to realize the control of the vehicle. move. Then there is the R gear, which is the reverse gear of the vehicle. After being engaged, the power output shaft of the gearbox will reverse and then the reverse operation can be carried out. The N gear can basically be regarded as the neutral gear on the manual transmission model. This gear will be used when the engine is required to keep idling. It should be noted that the automatic transmission will not completely cut off the transmission after switching to the N gear. The power connection between some internal transmission components and the engine. D gear is the driving gear of the vehicle. Normally, this gear is the most commonly used gear during the driving of automatic transmission models. After being engaged, the vehicle can move forward by stepping on the accelerator and automatically adjust the transmission ratio to save Heart and effort.
Next, let’s talk about the two gears S and L on some automatic models. The S on the S gear is the first letter of the English word SPORT, and the S gear is also It's sports gear. The basic work functions are similar to the D gear drive gear. The biggest difference lies in the response speed of gear shifting. After switching to the S gear, the gearbox will behave quite aggressively, especially the downshift will become more active to improve the vehicle’s performance. Sports performance. The L gear is the low gear of the automatic transmission. This L gear is used when the engine's strong traction on the vehicle is needed, such as when going up steep and down long slopes. After cutting in, the gearbox will lock the transmission ratio at a relatively high level. In terms of high values, it can basically be regarded as always maintaining the first or second gear of the manual transmission model.
The above is what the old driver pointed out. The P, R, N, D, S, and L gears on an automatic car represent the meaning. If you find it difficult to remember, you might as well try The specific content of this memory mantra is "P stop, R down, N empty, D go, S soar, L climb", which is concise, clear and accurate.
