自动挡 操作 Moving block gear, P, R, N, D, 2, L, OD, full solution + automatic transmission, gear shift, correct method of use 2010, 03 Friday, 19 October, 09:37 A.M. Online search, and I hope you have the same shrimp as useful Gear shift of automatic transmission Generally speaking, the gears of automatic transmission are divided into P, R, N, D, 2, 1 or L, etc.. P (Parking): for parking, it uses mechanical devices to lock the car Rotate the part so that the car can not move. When the car needs to stay in a fixed position for a long time, or before leaving the vehicle after the docking, you should pull the brake and push the lever to the position of "P". It should be noted that the P must be used only when the vehicle is completely stopped, otherwise the mechanical part of the automatic transmission will be damaged. In addition, the automatic transmission car with neutral start switch, so that the car can only "P" or "N" gear to start the engine, so as to avoid the other gear on the wrong start, the car suddenly jumped forward. R (Reverse): reverse gear, vehicle backward use. Usually according to the allocated link on the insurance button, Bogan will be moved to the "R" block. It should be noted that when the vehicle has not completely stopped, absolutely can not forcibly transferred to the "R" gear, otherwise the transmission will be seriously damaged. N (Neutral): neutral. Put the lever on the "N" gear, and the power between the engine and the transmission has been cut off. If the short stay, you can put the lever in this block and pull out the hand brake lever, and the right foot can be removed from the brake pedal for a short rest. D (Drive): forward gear, used for general road travel. Due to the various models of different design, so the "D" gear generally includes from the 1 block, high gear or 2 block, high gear, and because of changes in speed and load and automatic shift. Place the lever on the "D" gear and the driver controls the speed. Just control the accelerator pedal. 2 (SecondGear):2 blocks the forward gear, but the transmission can only change between the 1 and 2 gears, and will not jump to the 3 and 4 gear. Put the lever in the 2 gear, the car will start from the 1 gear, and when the speed increases, it will automatically turn 2 gear. The 2 block can be used as the upper and lower slopes, the benefits of this block is on the ramp or down ramp, the vehicle will remain stable in the 1 block or 2 block position, not because of unbalance, make block transmission continuously on the inclined load or speed. When the slope is lowered, braking is made with the low speed resistance of the engine, which does not cause the car to travel faster and faster. 1 (First, Cear):1 gear is also forward gear, but the transmission can only work in the 1 gear, can not change to other gear. It works best in severe traffic jams and on steep slopes. When the upper slope or lower slope is taken, the torque of the automobile engine can be fully utilized. The general automatic car stalls on a total of six locations, from top to bottom are: P, R, N, D, 2, L. P - Parking, parking. When you do not have parking stalls, here, at this time the wheels locked in a state machine can prevent slip. R - Peverse gear, reverse gear. Use it when reversing. N - None, neutral. Use this gear for temporary parking (e.g., red light). Notice that this stall indicates neutral position to prevent the vehicle from sliding on the slope, Be sure to step on the brakes. D - forward file, also called drive file. Needless to say, use this gear when you're moving forward. 2 - low gear, you can start with this gear on a very large slope or when you start on a more inclined slope. The principle of shifting gears in here, you can limit the automatic car stalls only in the low bit (equivalent to manual car the first and second gears) on the switch, in order to ensure the car get maximum momentum. L - Low, low gear. In the mountain, or long distance ramp, shifting gears in here, you can limit the automatic car stalls only in the most low-grade (equivalent to a manual car), can make the brake the use of engine power in the downhill, the driver does not need a long time to brake brakes the risk of overheating. OD----OD gear for speeding, high-speed use, to achieve fuel-efficient purposes. Having understood the gears of the car's automatic wave, you can enjoy the fun of driving an automatic wave car. Automatic block service After 1, the engine at startup, automatic transmission is a limit on the gear, which is the manufacturer for safety reasons and the transmission of the adjustment. Normally, the engine can be started only when the gear lever is in the gear P or N position. If the transmission lever is in the running gear, such as D, R, etc., the engine cannot start. The purpose of this restriction is to prevent cars from colliding with front and rear objects. If the novice can not start the engine, you should check to see if you've got the wrong gear. If it's not a P or a N block, you should adjust it first and start the car again; After the 2, using the method of N file: when you start the vehicle engine, without reversing and moving forward, you can first turn on the power brakes gear onto the N, and then the ignition, then hang into the D file directly forward, so as to avoid the P file after ignition, by R gear, the gearbox through a reverse impact! Another role is that when the car suddenly stops, you can guarantee the safety of the rapid shift gear to N gear ignition, and then start the engine; After 3, the car started to go, only the brake pedal lever can be removed from the P block or N block, the driving gear. Release the brake pedal and the car will run slowly. The reason why the brakes should be stepped in advance is for the safety of drivers and cars. Otherwise, when the engine starts, put forward gear, the car will move, at this time, if the driver does not respond enough, it is prone to collision accidents; 4, you can freely switch in driving forward gear. Although these blocks limit the highest gear that can be reached, they can be switched freely as long as the gear is matched to the speed; After the 5, driving must not shift to N slide, because the automatic gearbox lubrication, when driving gear pump discharge in the N above is not normal oil for lubrication, the gearbox parts temperature increases, causing complete damage! In addition, high speed neutral taxi is also very dangerous, and it is not fuel-efficient. Sliding to stop at low speeds can be put into the N file early, but it doesn't matter; After the 6, in the course of the vehicle must not be pushed into the P file, Unless you don't want a car. If you need to change the direction of the vehicle, you must wait for the vehicle to stop and then switch gears; After the 7, because of hydraulic automatic transmission mechanism for the gear box, and the liquid flow has a certain inertia, not sudden changes, so it is best to stop the car, and then hang into the reverse gear. It is absolutely forbidden to put the gear lever into the P gear before the vehicle stops completely. After parking, the engine must be turned off and put into the P file to remove the key. Many people used to stop directly to the P file and then turn off, pull the handbrake. Careful people will find that, after the general vehicle flameout due to uneven pavement around the small move, while the P gear box has a device and gear teeth bite, then the move will cause a little impact on the transmission gear! The correct approach should be: the car into the parking position, the brakes will pull the lever to pull the handbrake, N files, and then release the foot brake flameout, then the gear lever is pushed into the P file! Of course, this also belongs to the gear box excelsior protection; After the 8, long time parking must use the handbrake, otherwise it will damage the locking mechanism of automatic transmission. The difference between the P block and N block is a P block, the gear is engaged with the gear box, it is not only used for parking, and it will help the vehicle brake, in the parking stalls must be pushed to the P file, do not hang in N only to rely on the handbrake brake! Parking is especially important where there is a slope; After 9, when the red light, in the end should be using N files or D files, can according to their own habits, temporary parking brakes hanging in the D on the car without damage, because the gear box is provided with a torque converter group with one-way clutch reaction wheel, its role is to enlarge from the engine crankshaft in the engine torque. It is not idle rotation, only it will take effect until the engine speed rises. So the brakes when the red light is Never mind, linked to the N pull the handbrake anyway. Generally speaking, if the parking in more than half a minute you hang into the N pull the handbrake, if the parking time is short it is stepping on the brakes as well; 10, you give up D file exactly the habit of correct use of gear can completely overcome the lack of power. In addition to the D file, there are D3, 2, and 1 files. City driving, if the speed is not more than 60km/h, will use a file below the D file, so that the sharp acceleration, and avoid the carbon production; when the speed exceeds 60km/h, use the D file running, not only fuel, will not damage acceleration; the road in the mountain, then according to the the use of 2 or 1, in addition to maintaining strong torque output, engine braking effect can avoid excessive use of foot brake, to ensure traffic safety. Automatic car D file does not have the engine brake function, and will increase with the downhill speed continues to shift to the high speed, the speed more and more quickly, must not stop using the foot brake to control the speed, it is easy to use and excessive heat generated due to brake failure, which is very dangerous. Therefore, the automatic driving car go a long downhill, D driving must not, in case of emergency. The automatic transmission system and the manual transmission system are two completely different designs, both in addition to the final purpose of the same work, the principle of movement and performance are different. But whether it is manual transmission or automatic transmission, in the correct way, the theory should have approximately the same performance. Cars that feel automatic are less powerful than manual ones, mainly because they don't operate properly. People are already familiar with the use of manual gear, and it is also clear that the best time to change gears is easier to use. Automatic car, people tend to be less likely to use, and often simply use the D file, all the way to the end. This is considered to be the driving method of automatic car to the right, though not wrong, but the feeling of driving easily found, but feel it is not the taste, seems to be in the overall performance is slightly inferior to a car with a manual transmission. This is not the case. There are many uses. If you use the correct control method, the automatic car will also be superior to the manual performance. The automatic transmission system is designed to allow the D gear to automatically change between 3-2 (4 speed or 3 speed automatic transmission) or 4-3-2 (5 speed automatic transmission) cars depending on the vehicle speed. This design, in the downtown stop and go case, the automatic transmission will be in 3-2, 2-3 or stalls constantly changing. The torque performance of the vehicle acceleration depends on the engine, control by the owner in the maximum torque output can shift manual transmission car, automatic transmission car under the action of frequent shift will make the driver feel weak and feeble "car performance". This situation is more evident in the continuing downhill sections. One way to solve this problem Without considering the premise of fuel consumption, usually the car also started with a big throttle. Most automatic transmissions now have learning capability, and if you step on the accelerator more deeply, the gearshift will change the original shift point automatically. For example, the original set is 2500 rpm, and after the big throttle will be 4000 or more gear up, so that the actual output torque is much greater than before, the vehicle's power is stronger. If you often use the throttle, automatic transmission program will remember your driving habits, automatic transmission shift points will change the factory when both power and energy saving setting, automatic high engine speed stall point. In addition, if your car has the mode of movement, the choice of motion mode, driving, will also have the same effect. Solution two Abandon the habit of D gear, and use the gear automatically to completely overcome the lack of power. If you have higher vehicle handling requirements, the first idea of automatic car driving is to get rid of the habit of D gear. Many automatic models have 1, 2, 3 stalls besides D. The urban speed is not fast, can be placed in the 2 stalls stalls or 3 stalls, the mountain on the 2 or 1 files, you will find the car seems to run up the shaman, not only strong, but more lively. Some may wonder whether such an operation would have a bad effect on the transmission system Will it compare with gas consumption? The answer is not only not, but also more advantageous. Because, since the transmission system design has these stalls, it means that they have some divisions, the correct operation will not cause damage. At the same time, it is possible to avoid dragging the vehicle with higher grade, and the fuel consumption will inevitably be lower, It also reduces carbon accumulation in engines. This does not stall the concept of manual gear owners are very strong. Automatic car driving in urban areas, if the speed is not more than 60km/h, will use a file below the D file, so that the sharp acceleration, and avoid the carbon production; when the speed exceeds 60km/h, use the D file running, not only fuel, will not damage acceleration. When driving on the mountain road, the 2 or 1 gears should be used according to the situation. Besides the strong torque output, the brake effect of the engine can be avoided and the traffic safety can be ensured. Automatic car D file does not have the engine brake function, and will increase with the downhill speed continues to shift to the high speed, the speed more and more quickly, must not stop using the foot brake to control the speed, it is easy to use and excessive heat generated due to brake failure, which is very dangerous. Therefore, the automatic driving car go a long downhill, D driving must not, in case of emergency. Even if you buy automatic car in order to avoid the shift of trouble, but also a little diligent a bit. At low speed, change into the gear below D. At high speed, rest assured and easy to use the D file and boldly move forward. This will result in a half effect.
