one stall Introduction
so-called automatic transmission, by definition is not the driver to manually shift the vehicle according to driving speed and traffic conditions automatically select the appropriate gear while driving. But why are so many automatic transmission gear automatic transmission, it now first function of the various stalls and a brief introduction.
first to the new Accord Honda Accord as an example of transmission has P, R, N, D, 3,2,1 a few stalls:
P on behalf of parking stalls, parking use (off the engine)!
R on behalf of reverse gear, this I believe I need to explain it!
N on behalf of gap, the gap, and a manual means for short-term parking to use!
D, said forward gear, the gear transmission in the next 15 case files based on speed and throttle automatically switch
3 is also a forward gear, the gear 13-speed automatic transmission in the next switch, do not ascend two steps of 4,5. Very smooth in traffic when used as a constraint file to avoid 3 files and 4 files file between the situation of a jump! (Specifically, how to avoid it is to do will be described below)
2 that two files, the file, the gearbox in 2 files on the slippery road to start, or the slow move forward as a constraint file to use, can be avoided, and 1 and 2 files 2 and 3 files file between the jump!
1 is a file, this file, the transmission in first gear. This I do not explain it, you look at the situation with it:)
other automatic transmission vehicles, there are stalls that may occur S file, L files (such as the Honda Fit, etc.) There's snow in the gearbox has a key (such as the Buick racing Europe, etc.),
mbt shoes outlet, OD OFF button and so on.
S said the campaign mode (sport) in the stalls are free to shift under the gearbox, but the opportunity to shift the time delay, so that the engine at high speed to maintain a long time, so that the vehicle in Power large. Obviously, this will of course result in increased fuel consumption.
L said low speed should be 1 and the new Accord is a meaning, when the stalls will remain in a file transmission and not upshift.
key means snow for slippery road start, press this key when the vehicle will not start from a file, starting from the 2 files to reduce the torque output to avoid the vehicle in the wet slip road at the start.
OD OFF button that is the most high-end prohibition, have the keys of the vehicles are often not D3, because the press this key to the highest gear (4 speed gearbox) 4 file has been banned, the work is equivalent to D3.
should be noted that in some vehicles above the 2 gearbox which does not represent a single 2 files, but 12 files (such as the Buick cars) when using this gear transmission will automatically switch between 1,2 and will not rise to the more upscale.
automated manual gearbox might not divided so many stalls, in addition to its P, R, N (these three files are automatic transmission cars must have a), the Forward is a D file (such as the FAW Mazda 6), the function of other stalls to manual mode can come true.
Second, the driving skills
automatic transmission vehicles, the greatest advantage is convenience, especially in the traffic jam, especially the uphill run into a traffic jam is a major advantage that automatic transmission is even more evident. Automatic transmission cars are more and more popular, the development of advanced countries from the car seems to have most of the vehicles have automatic transmission transition, automatic transmission to replace hand-file the main vehicle of everyday driving is the car trend. Many riders are driving a vehicle autopilot D in the end,
mbt lami shoes, this course is to open automatic transmission car, but if the right combination of proper road traffic conditions to select the correct gear, then you can greatly reduce the automatic transmission burden, reduce transmission wear. To let everyone understand the truth more easily to the actual driving conditions with an example of the use of automatic transmission gear restrictions file.
To learn how to properly file a reasonable restrictions on the use, first of all you riders know their vehicles to clear the shift timing and shift transmission range. Transmission shift each time the car is not the same, normal driving when the engine speed automatic transmission gear shift is called interval, under normal driving range in the automatic transmission's shift 20,002,500 rpm. I was the new Honda Accord as an example to illustrate, we can understand the basis of this standard to shift the car yourself time: the new Accord's transmission is based on the driving situation the driver automatically adjusts shift timing (better now The automatic transmission are basically the function), if you re throttle, the transmission will automatically shift the timing delay in order to obtain long-β suitable Ben Lai Su goblet thumb cockroach? so contented song? 000 will rise after the file transfer the whole step of the case will go to speed up to red zone was promoted to the next file (which set the basic file to replace the role of S). Conversely, if you step on the gas transmission will be the first in the slow speed of less than 2000, when promoted to the next file with the driver to achieve the intent and purpose of fuel economy. In normal driving the shift timing of the new Accord 2400 switch is generally the engine speed when the stalls at 20,40,60,80 code will be promoted to 2,3,4,5 file. I said above, the gearbox is not set in stone dead time shift, it can according to your intentions to achieve stalls earlier or later switch.
(Note: The new Accord with a 5 forward gears, automatic transmission cars are now available in most of the 4 forward gears, the more advanced high-end cars there are 6 forward gears, the actual operation is not do differently)
I would like to have heard a lot of riders to step on loose about automatic transmission can shift up in advance, and accelerate faster this concept is not entirely correct, automatic transmission step on what song can be achieved in advance upshift is correct (but it should also choose a good step, loose time), but this is the case at the expense of speed to a relatively fuel-efficient purpose, does not make the vehicle accelerate faster. Concrete examples: (or driving a new Honda Accord:), start driving soon after the stalls ascend 2 file (Note: 12 file does not need to do the following, as a greater resistance to stall the engine, after you release the throttle the speed down quickly, you will stall as long as the slow step on the gas promoted to second gear when appropriate), then step on the gas a little weight (in quick acceleration), when the engine speed just after 2000, when the speed of about 30km, slightly loose on the gas, the transmission will be promoted to three files in advance, and then depresses the accelerator to speed 2000, speed 50, release the throttle, the transmission will be promoted to four files in advance, the same rate also appears to be about 70 When promoted to the earlier 5-speed gearbox. This can be accelerated without affecting the under the situation too much into the file in advance. Shift the timing of different vehicles or different, you bikers know their vehicles in the case, according to their own vehicles shift situation, choose the timing more than the purposes of operation. Moreover, even if not to advance into the file, so that proper control with the throttle to shift time is also good for what, when the speed range up to shift, you close the throttle as long as the light, automatic transmission will automatically upshift to instructions oil in the moment you receive the engine speed will drop some, just in the tooth than just upshift convergence time you refuel before the trip, you will find the entire shift process smoother, more comfortable ride. The above process needs to have some contact with their car and understanding to complete the implementation of you bikers do not rush, wait for you to find out the temper of the car to make the above operation to handy:)
* Note that: to achieve early upshift, and then step on the gas when the degree is not too large, otherwise the transmission would think that drivers need to hard acceleration, and the current power output can not meet the requirements of stall automatically downshift, then jump back to a lower gear on the resulting file! This car fans can test several times in the operation of motor vehicle transmission to master control of their own scale.
above that are driving the vehicle under normal D case files to understand this, let's talk about the restricted file! Why is understanding of constraints file to figure out the vehicle before the shift time? This is because, under normal driving limit file is used when the vehicle speed and engine speed range in the shift when constantly hovering on the automatic transmission to shift for control I think this is the general driving limit file the most accurate interpretation of the role (this interpretation is definitely my original ^ _ ^) introduced the original automatic transmission seen many articles, which almost all these words: \bit to travel ... ... \I said above, the limit file actually only happened in the car in gear when wandering interval will be effective.
For example, if the stability of the vehicle traveling 40 yards, then stalls should be 3 files (according to advance into the file, 3 files speed interval 30km50km), in this case file or use D D3 is simply no distinction between files, the transmission will always be stable at above 3 files, files do not cause jumps. Or slower, steady speed of the vehicle to travel 10km, when you use the D file or use a file is no different, the transmission of the stalls is a file, there will not be lifting gear changes. When that limit the use of file it? File should be restricted when the fast traffic slow to a speed not stable before the line of cases. For example, in 4050 the speed has been among the shaking, when transmission is likely a top of a file in 3 files in 4 above, or up and down. This process will result in accelerated wear and gearbox production of coke, when restrictions on use file to control the jump D3 generated files, so that stability of the 3 files on the gearbox, not to the 4 files on the beat. The same situation also appears in the 12 stalls, 23 stalls in the shift range, such as traffic jams, the car moving slowly, it may speed up to 20 instantly,
skechers shoes, but soon we stopped the process after a gearbox, 1 file 2 file on the rise, and then immediately jump back to a stall the process again, this time limit if the selected file 1, you can avoid this process, reduce transmission wear and tear! So your vehicle to clear their vehicles earlier case of shift intervals, as appropriate, choose to limit the file, which is protection of the automatic transmission is absolutely good!
work restrictions when there are two files, that is, when the uphill and downhill. First, it uphill, when the vehicle uphill, if steep, climbing vehicle D may be what happens to it, when the vehicle is at a lower gear, the torque output to meet the requirements of the vehicle uphill, then the vehicle will accelerate uphill, when the shift into the post-interval, the transmission will be promoted to a higher gear, while the high stall torque output may not satisfy power requirements of climbing, then the vehicle will slow down, slow down when, after it, the gearbox and will continue climbing gear down. This process of transmission in climbing will be so again, jumping up and down, this process will accelerate the transmission of the same wear and coke production. So in the process of climbing owner should select the appropriate limit under the stall, if steep,
mbt outlet, or even be put on 2 or 1 to complete the climb and then be put on driving when normal driving.
downhill when the file is restricted to use as an auxiliary brake, we all know that driving manual transmission car in the mountains, down a long slope, when a large slope (of course not necessary to do so under the Xiao-Po Operating a) can be linked as an auxiliary brake in the lower gear, while the autopilot is not in the D file when the role of auxiliary brake, the faster it will only be more slippery. At this time limit can be put on file, to achieve increased use restriction stall the engine as a brake with auxiliary braking to reduce brake pressure of work. This is without my having to explain that, you should have a clear owner.
limit file sometimes used as forced downshift, that you need a strong torque output for a long time, you can use it to stall at a relatively low gear up to achieve, or overtaking , you can pull down the stalls. However, according to your automatic transmission is to determine whether the degree of throttle downshift, for example, in front of you super-slow, you can first go on a foot off the accelerator and then, when the transmission will automatically drop a file or even 2 file to meet your power requirements, the completion and release the throttle to overtake, stall speed will return to your current gear right, in which case you no need to use restricted files, use the throttle to control the light on it .
automatic transmission car in motion the use of the whole probably introduced, and you see riders with their own vehicles, this situation can understand what I hope this I argue, can help us . Here to remind you that the proper use of restricted files can indeed be well protected transmission, reduce wear and tear, reducing coke production, but the files do not indiscriminately use restrictions, because the file is closed limit higher gear, in this case Even if you pull the engine under the red zone it will not upshift, the wrong use of restricted files on the engine and gearbox caused tremendous damage! ! If you are not really determined to learn the use of restricted files, then I advise you to forget a D in the end, this relative is also safer:)
III automatic transmission Notes
then add some automatic transmission cars need to pay attention:
1) only in the P, N two steps can be powered vehicles only, file extraction from the P shift lever must slam the brakes. N file is when you start to use directly after the vehicle started moving forward, you can first power (not the name of the engine), slam the brakes pulled the stalls N, then the ignition, and then linked directly into the D file forward, to avoid sparking in the P profile, you need through the R file, so that transmission through a reverse shock! It's a bit better, huh:) Another role is to suddenly turn off when in motion, you can ensure the safety of the stalls quickly pushed to the N file ignition and then start the engine.
2) general stalls in the N, D, 3 shift when switching between without pressing the button, from 3 to hang down the restrictions necessary to press the shift button file, do not hang from the low to high Press shift button. (Stand rod button, there is no dislocation arrangement of gear shift lever button, such as the Buick Excelle, etc.)
3) moving into the N files must not hang glide, because the automatic transmission needs lubrication, when moving into top gear on the N when the oil pump is not properly lubricated will lead to internal parts gearbox temperature, resulting in complete damage! Another is the gap sliding speed is very dangerous, and not fuel efficient! Introduced in this area there are many, I will not go into details. Slide the stop to advance the low speed link into N files, is no longer being affected.
4) automatic transmission car in motion must not be pushed into the P file, unless you do not want car:) a change in the driving direction (forward or backward to change forward to change back) is from the reverse linked into the file or move forward into the reverse link, be sure to wait before making the vehicle completely stopped operating.
5) moving the end stop, turn off automatic transmission cars must be linked to file out into the P key. Many people used to stop and directly to the P file and then turn off push, pull the hand brake. Observant people will find this operation, turn off the vehicle due to road surface roughness after the general will move around a little bit, and then have a bite P-speed gearbox and the gear device is a bite, and when the move would result in gear little impact! The correct way is: cars into the parking position, the shift lever will be pulled slam the brakes N file, pull handbrake, release the foot brake and then turn off,
mbt shoes, push the shift lever and then the final P file! Of course this is also part of the gearbox better protection:)
6) Also on the temporary parking (such as red light), the automatic transmission in the end the use of N or D file file has been some controversy over this issue, in fact, does not matter. N or D are not wrong, but according to their habit, a temporary parking slam the brakes on the car hanging on the D did not damage, because the gearbox has a torque converter one-way clutch with the reaction wheel, whose role is to enlarge The torque from the engine crankshaft, the engine idle speed is not under the rotation, only to be the engine speed increases, it will work. So when you slam the brakes are not related to red light, pull the hand brake is also linked to N no harm, the benefits can make the right foot look at the activities, seize the time to properly relax:) can be applied to a hard of indicators: If parking in the semi- minutes into the N pull your handbrake to hang it, if the parking time is short it is like stepping on the brake so noteworthy is that this is the interpretation of general automatic transmission car, when your vehicle when you have special requirements can not follow this to, for example,
mbt sport shoes, Buick sail, which in its clear emphasis on the use of CD-ROM, and temporary parking can not hang in the N file, because it features automatic gap jump, slam the brakes on your speed after a few seconds box will automatically jump the gap. This I do not really understand, Is it the gearbox design has two neutral? It just jump the gap and the gap is not as I hang it? ?
