Timely four-wheel drive. Computer-controlled four-wheel drive. When the wheel slips, it will automatically catch the slipping wheel. It belongs to a relatively low-order four-wheel drive technology.
What is a smart and timely four-wheel drive? Explain in detail as much as possible. Thank you.

The difference between intelligent four-wheel drive and timely four-wheel drive
The so-called timely four-wheel drive means that the car only transmits power to the front and rear axles when necessary, and it becomes a four-wheel drive mode. Under normal circumstances, the car is actually a two-wheel drive mode, while the full-time four-wheel drive means that the car is in a four-wheel drive state at any time. For timely four-wheel drive vehicles, such as Honda's CR-V, under daily driving conditions, the power of the engine is transmitted to the front axle, and the power transmitted from the drive axle to the rear axle is not meshed with the rear axle (in fact, there is still a little connection), and the rear axle basically has no driving force. After the front wheel slips, the drive axle starts to connect with the rear axle, and then the rear axle starts to be driven. At this time, the waiting really changed. ...
What does Tiguan Automobile Smart Full-time Four-wheel Drive mean?
The low match is two-wheel drive and the high match is four-wheel drive. The high-equipped Tiguan chassis is the same as the low-equipped Touareg chassis. There is a 4MOTION disk behind Tiguan, that is, high allocation, which is Volkswagen's full-time four-wheel drive system.

What does smart four-wheel drive mean?
Intelligent timely four-wheel drive is to accurately control the intelligent transfer box to transmit controllable torque to four wheels according to the wheel slip or steering information, thus improving the acceleration, stability and fuel economy of the whole vehicle. When parking, the torque transmitted to the front wheel is very low or even zero, which improves the convenience and comfort of operation. When ABS is working, the power transmission of the front wheel is quickly cut off within 60ms to ensure the stability of the whole vehicle during braking. When accelerating, the four wheels achieve the maximum traction and the acceleration is better. Communicate with other safety systems on wet roads to obtain the best traction and safety efficiency.
Four-wheel drive, okay? Or smart four-wheel drive?
In fact, the mechanical structure of the two is the same, both are four-wheel drive. Honda's so-called intelligent four-wheel drive only adds a computer (the computer will decide whether to drive two or four wheels according to different road conditions, and even distribute unequal power to the front and rear wheels), and Subaru's full-time four-wheel drive is the same, adding a computer, except that Subaru did not say the word wisdom. Personally, I think Subaru's full-time four-wheel drive is definitely better. After all, this is one of the signs of Subaru (and horizontally opposed engine).
What does smart four-wheel drive mean?
That is, when the computer controls when a four-wheel drive is needed, it is a four-wheel drive, which is usually a front drive.

Is Shanghai Volkswagen Tiguan four-wheel drive a real-time four-wheel drive or a smart four-wheel drive? What's the difference between them? What are their advantages and disadvantages?
Now the four-wheel drive on the market is mainly divided into full-time four-wheel drive and timely four-wheel drive. Tiguan's four-wheel drive is called "intelligent four-wheel drive" by the public. In fact, it belongs to the timely four-wheel drive, which is considered as a semi-four-wheel drive.
Full-time four-wheel drive is driven by mechanical means, and it is a four-wheel drive whenever and wherever. This kind of driving with high cost and high fuel consumption is specially designed for off-road vehicles. A timely four-wheel drive like Tiguan is not a four-wheel drive at any time. The computer will automatically analyze the road conditions and transmit the power to the rear wheels. On a flat road, it is a two-wheel drive state. When encountering potholes, it will distribute power to the rear wheels and become a four-wheel drive.
The advantage of full-time four-wheel drive is sufficient torque at any time and strong off-road ability. Disadvantages are high space, cost and fuel consumption.
The advantages of timely four-wheel drive are low cost, light weight and low fuel consumption. The disadvantage is that off-road capability is not as good as full-time four-wheel drive, but slightly better than two-wheel drive.
What does wisdom and timely four-wheel drive mean?
What do you need to know first to understand full-time four-wheel drive?
It is a part-time four-wheel drive.
. The part-time four-wheel drive is the most common four-wheel drive system.
It's called part-time 4wd because you can't work in.
Use on roads with good adhesion. in default of
There is a central differential, which drives back and forth when turning.
The speed difference between shafts can only be determined by a certain
A tire skidded to offset it. When the road is connected
When the strength is high, it is difficult for the tires to slip. because
Well, if it's on a road with good adhesion.
You can't use a part-time 4wd. This is also a timeshare.
Four-wheel drive got its name. After learning about part-time 4wd, you can know everything.
The four-wheel drive is relatively simple. Full-time four-wheel drive
It is the addition of the Central Committee on the basis of part-time 4wd.
Differential, so that the rotation between the front and rear transmission shafts.
The speed difference has been successfully resolved. Therefore, it can
Suitable for any road surface. Full-time four-wheel drive is also obtained.
Name. On the basis of full-time four-wheel drive, Geng also evolved a constant.
Four wheel drive (transfer box without two wheel drive mode).
Constant time four-wheel drive adopts intelligent transfer box.
This kind of transfer box can have different outputs according to needs.
Driving force of front axle. Okay, intelligent transmission.
The power output can be 0- 100%.
Change. Another thing I have to say is that some manufacturers.
The so-called full-time four-wheel drive or constant-time four-wheel drive.
The real full-time four-wheel drive or permanent four-wheel drive will always be
In the process of engraving, the driving force is output from the forward driving system.
Yes, and those so-called full-time four-wheel drive or constant time.
The four-wheel drive system uses a viscous coupler.
Transfer case structure. This kind of transfer box is in normal condition.
In this case, the power output of the forward drive system is not allowed.
Only when necessary (climbing mountains or sliding the rear wheels)
) to drive the system to output power forward. if
In this sense, or in a strict sense.
Generally speaking, this is not a full-time four-wheel drive system.
Yes
