Introduction diagram of the most automatic gear position

The gears on a general automatic car are: P (parking gear), R (reverse gear), N (neutral gear), D (forward gear) and D1; 2; 3; M+; -; (limit gear), l (low gear) s (sport mode).

use a shorthand formula to introduce: "p stop, r reverse, n empty, d go, s soar, m hand, l climb". Is it much easier to remember like this?

let's talk about the automatic gear.

P gear: parking gear.

when the shift lever is in the p position, the interior of the gearbox is in neutral state, but the output shaft is mechanically locked. At this time, the car will stop at the same place even if it doesn't step on the brake. It is generally used when the car is parked for a long time.

when shifting into p gear, the car must be in a completely stationary state, and it is forbidden to shift into p gear without stopping the car, and at the same time, the hand brake must be pulled. In addition, when parking on a slope, you need to pull the handbrake first and then put it into P gear.

R gear: reverse gear.

when the joystick is in the r position, the rotation direction of the output shaft of the transmission is opposite to that of the engine, so that the car can run backwards.

when shifting into r gear, the car must be in a completely stationary state, and it is not allowed to shift into r gear without stopping the car.

N range: neutral.

when the joystick is in the n position, the gear inside the gearbox is idling and the clutch is not engaged, so the load of the gearbox is the minimum. N gear is generally used when stopping for a short time, such as waiting for a red light, and the gearbox should be hung on N gear when the car is towing. The difference between it and P gear is whether the output shaft of the gearbox is locked, and other functions are the same.

D gear: driving gear.

this is a gear that we use most often. When the joystick is in the D position, the gears in the gearbox automatically switch between the lowest gear and the highest gear according to the change of vehicle speed, throttle opening and other factors and the set shift rule. In most cases, we can use D gear to drive.

S gear: sport mode.

after buying a car, many friends in this stall have been driving it for several years and don't know what it does! S-gear movement mode, in which the gearbox can shift gears freely, but the opportunity to shift gears is delayed, so that the engine can keep at a high speed for a long time and output a large torque immediately, which increases the power of the vehicle, and it will be slightly worse to use other gears.

Although cars have S gear, it is still not recommended that most car owners often use this gear, because using S gear will increase fuel consumption. Because of the large fuel injection at high speed, the fuel consumption of the car will definitely increase.

Although it is said that the speed can be increased instantly, this gear is usually used when overtaking. This gear is actually a delayed upshift without changing other working links.

3, 2, 1 (or l): digital limit gear.

when the joystick is in these gears, the gearbox can only be switched in the limited gears, and cannot be switched to the high gear. For example, hanging on "3" means switching between first, second and third gears, hanging on "2" means switching between first and second gears, and hanging on "1" or "L" means first gear.

There are certain skills and requirements in the use of these gears: "1" or "L" is the lowest gear of the gearbox, and it is generally used only when extremely powerful power is needed, such as climbing a big slope or towing a heavy vehicle; "2", also known as the snow gear, is generally used when starting under slippery road conditions such as snow and ice roads, and can also be used under very congested urban road conditions; "3" is widely used, for example, when overtaking, you can get stronger power and make overtaking easier; When climbing a long slope, it will be better to shift into the third gear, and it will also avoid frequent gear jumps on the slope; When going downhill, shifting into third gear can make better use of engine braking, avoid the car slipping faster and faster, and go downhill more safely, and so on.

M gear is in manual mode, and the+and-signs on it actually have similar functions.+means to shift up and-means to shift down, which is also used for uphill and downhill. The vehicle can be directly switched to manual mode while traveling, and there is no need to stop and switch.

One of these limited gears is slightly special, which is called by the insiders. In fact, the logic of direct selection is that in manual mode, when you choose a few gears, that is, a few gears. Generally, the gearbox will not intervene to change the gears, but will always keep the gears you put in. It will help you downshift unless your speed is really slow. This kind of gear logic appears mostly in sports cars or models that emphasize sportiness.
