Intelligent continuously variable transmissions (IVTs) are among the latest technological developments in automotive powertrains and have attracted considerable interest from manufacturers and engineers in recent years. This technology can be considered an evolution of the continuously variable transmission (CVT); the key difference lies in the IVT’s ability to reduce gear ratios to zero , which distinguishes it from other transmission types.
This article provides a comprehensive overview of continuously variable transmission (CVT) technology, including its history, operating principle, internal structure, advantages and disadvantages, the differences between it and continuously variable transmissions (CVT) and automatic transmissions (AT), and its development prospects in the automotive industry.
Chapter 1: Introduction to Electrical Power Transmission Systems
From the invention of the automobile to the present day, the transmission has been one of the most important components influencing driving comfort and vehicle efficiency. The main functions of the transmission include:
-
The engine power is transferred to the wheels in an optimal ratio.
-
Reduced fuel consumption
-
Achieve optimal acceleration and road grip.
-
This reduces wear and tear on the engine and transmission.
Over time, various types of gearboxes have been developed:
-
Manual transmission (MT)
-
Classic automatic transmission (AT)
-
Dual-clutch transmission (DCT)
-
Continuously variable transmission (CVT)
-
Intelligent electronic transport
-
Now let’s turn to the intelligent continuously variable transmission (IVT).
Continuously variable transmission (IVT) technology is one of the innovative technologies that could play an important role in the transmissions of city cars and even hybrid cars in the future.
Chapter Two: What is an IVT transmission?
The abbreviation IVT stands for Intelligent Continuously Variable Transmission . This type of transmission is similar to a continuously variable transmission (CVT), but differs in one essential point:
IVT technology makes it possible to reduce data transmission rates to “very low” or “zero” levels.
This function allows the engine to operate the vehicle under very quiet conditions and without significant power consumption, which considerably reduces fuel consumption.
Some engineers call the continuously variable transmission (IVT) an improved or intelligent continuously variable transmission , but in reality, this transmission is not just an improved version; it also has a new control mechanism.
Chapter Three: IVT Transmission Structure and Function
To better understand the structure of IVT, we first need some information about CVT.
In a continuously variable transmission (CVT), power is transmitted via two conical pulleys and a steel belt or chain . Changing the distance between the pulleys alters the effective diameter of the transmission, thus enabling continuously variable gear ratios.
The IVT transmission uses the same components but is equipped with an intelligent electronic control system that can precisely select the optimal power transmission point . Furthermore, the IVT transmission features an innovative internal mechanism that allows operation without a gear ratio.
Key features: Zero percent
In this case:
-
The output shaft stops rotating.
-
The input shaft can rotate freely.
-
The car now runs more smoothly without having to increase the engine speed to maximum .
This function is not available with any transmission, including continuously variable transmission (CVT) or standard automatic transmission (AT).
Chapter Four: How do intelligent technologies work in intensive vocational training?
The intelligent component in this process is the electronic control unit (TCU) . This control unit makes decisions by analyzing the following information:
-
speed
-
accelerator pedal angle
-
Motor
-
Engine operating conditions under different loads
-
Engine and transmission temperature
-
road slope
-
Driver assistance systems (e.g. traction control system )
This transport controller uses data to select the optimal transport factor and thus achieve the following results:
-
Reduced fuel consumption
-
Ensuring sufficient acceleration
-
The switching process must be absolutely smooth.
-
Reduce your consumption.
Therefore, the driver has the feeling that the car moves very intelligently, smoothly and harmoniously.
Chapter Five: The Difference Between CVT and Continuously Variable Transmission
Although CVT transmissions and continuously variable transmissions are similar in their mechanical structure, there are some differences between them:
1. Create a zero profit.
-
Continuously variable transmission: not possible
-
IVT: Yes
2. Gradual introduction
-
CVT transmissions are often a bit “loose”.
-
The IVT transmission ensures exceptionally smooth starts.
3. Fuel consumption
-
Compared to the continuously variable transmission (CVT), the invertible automatic transmission (IVT) can also reduce fuel consumption.
4. Noise
-
Continuously variable transmissions (CVTs) sometimes produce a monotonous noise at high engine speeds.
-
The variable transmission (IVT) significantly reduces this problem through intelligent control.
5. Durability
-
The design of the continuously variable transmission (CVT) reduces the load on pulleys and belts.
Chapter Six: Advantages and Disadvantages of the IVT Transmission
To use
1. Extremely low fuel consumption
The main goal of continuously variable transmission (CVT) technology is to improve fuel efficiency. A gear ratio of zero when starting off helps to avoid power losses from the engine.
2. Ultra-soft
The driver feels no vibrations or jerks when changing gears.
3. Reduced engine noise
The intelligent system controls the engine to ensure it runs at optimal speed.
4. Increased compatibility with energy-efficient engines and hybrid engines.
Continuously variable transmissions (IVT) are ideal for small cars and hybrid vehicles.
5. Reduce your consumption
Smooth and well-thought-out movements reduce the stress on the components.
Shortage
1. Limited network bandwidth.
Not suitable for heavy and powerful vehicles.
2. High production and operating costs .
This technology is new and complex.
3. This requires special lubricants and a careful maintenance procedure.
Maintenance costs might be slightly higher.
Chapter Seven: Application of Continuously Variable Transmission Technology in Modern Cars
Independent transmissions (IVT) are more commonly found in vehicles:
-

It was used.
Leading companies in this technology sector include:
-
Hyundai – Intelligent Transmission (IVT)
-
Kia – Next Generation Integrated Transmission (IVT)
-
Other Asian car manufacturers
These companies developed the continuously variable transmission (IVT) to compete with the advanced continuously variable transmission (CVT) and the energy-efficient automatic transmission.
Chapter Eight: How does a vehicle inspection affect the driving experience?
Drivers who have used vehicles with continuously variable transmission (IVT) typically report the following advantages:
-
It reacts faster with gases.
-
Initially, the movement progressed slowly.
-
Reduction of disturbing engine noise
-
You want to feel like you’re driving a luxury car, but with a fuel-efficient engine ?
-

In fact, the IVT transmission combines, in a sense, the best features of both a CVT and an automatic transmission.
Chapter Nine: The Future of Satellite Television
IVT technology is still in an early stage of development and its prospects are as follows:
-

The intelligent continuously variable transmission (IVT) is an advanced and efficient technology that combines a stepless gearbox with an intelligent electronic control system, elevating the driving experience to a whole new level. The main advantage of the IVT lies in its smooth gear changes , which reduce fuel consumption during acceleration. It also offers further benefits such as smooth shifting, reduced wear, suitability for city driving , and environmental friendliness , making it the ideal choice for next-generation vehicles.
Despite some limitations such as high production costs and lack of suitability for high-performance vehicles, continuously variable transmission (IVT) technology is expected to play an important role in the development of hybrid and fuel-efficient vehicles in the coming years.
If car manufacturers succeed in reducing the production costs of this technology, continuously variable transmissions (IVT) could soon become one of the most common transmissions in city cars.
