AMT, also known as Semi-Automatic Transmission (SAT) or Clutch less Manual Transmission, is a type of automated manual transmission (CMT).
The primary function of an AMT, as the name implies, is to automate manual transmissions, which means that the driver is no longer responsible for pushing the clutch and shifting gears using a stick. AMT is classified into two types: single-clutch and dual-clutch.
While the dual-clutch has demonstrated superior performance in terms of smooth gearshifts and quick throttle response, the single-clutch alternative is more cost-effective. It aids Original Equipment Manufacturers (OEMs) in maintaining pricing control.
AMT, or Automated Manual Gearbox, is technically identical to a manual transmission with the exception that sensors and actuators conduct clutch operation and gear shifting. There is no clutch pedal in an AMT vehicle; only the accelerator and braking pedals are there.
Manual gear shifts are also possible with AMT, by pushing the gear lever forward for upshifting and drawing it backward for downshifting. AMT Transmission employs hydraulics and computers that are linked to the vehicle’s Electronic Control Unit, or ECU. The shifting patterns are pre-programmed on the ECU and operate mostly within a pre-set RPM (Revolutions Per Minute) range.
The ease of AMT over manual gearbox is a key advantage; because manipulating the clutch is not part of the driver’s duty, it lowers tiredness. AMT is more fuel-efficient than automatic transmissions or conventional automatics because it enables more of the engine’s energy to go to the wheels manually, which is similar to a manual gearbox.
The automatic manual transmission system offers significant advantages in terms of fuel efficiency, acceleration, smooth operation, and dependability. These benefits are significant drivers of the automobile AMT industry.
Furthermore, an AMT has the benefit of being able to convert any manual transmission into an automated manual transmission system, which is boosting the automated manual transmission industry.
Asia-Pacific is anticipated to expand the quickest. With a constantly expanding automobile population, nations such as China, India, and the ASEAN countries are expected to see significant demand for automated cars in the Asia-Pacific area, particularly India.
One of the greatest operational costs for commercial trucks servicing global economies is fuel consumption. Transmission systems are the primary elements in cars that aid in fuel efficiency, and the AMT system is successful in supplying the appropriate gear at the appropriate moment.
AMTs give 5 percent -8 percent miles per gallon savings compared to manual transmissions, depending on vehicle use and driver driving ability.” Inexperienced drivers may also ride AMT cars without significantly affecting fuel consumption due to their excellent fuel efficiency. AMT technology strikes an ideal balance between vehicle cost and fuel economy. Efficient technology has a longer life cycle.
Commercial Vehicle demand has grown as a result of increasing purchasing power, growing population, fast urbanization and globalization, and a willingness to own a vehicle. The automated manual transmission industry has seen various development possibilities as a result of technological improvements.
Increased demand for technology-enhanced automobiles at reduced pricing is expected to provide substantial possibilities for the automated manual gearbox industry.
The expense of automated manual transmissions is a major impediment to the market. It costs somewhat more than the manual transmission. Transmission costs more because of the electronic control unit and the hydraulic system.
Automated manual transmission (AMT) is a Formula-1-derived electro-hydraulic system for automating manual transmission. It combines convenience with reduced usage and may be used to any gearbox, with cheap production costs as compared to standard automatic transmissions.
Many early versions of these semi-automatic gearboxes, such as Auto stick, simply control the clutch and frequently employ different kinds of clutch actuation, such as electro-mechanical, hydraulic, pneumatic, or vacuum actuation.
The most recent technology has been the revolutionary auto gear shift technology being implemented by the OEM companies around the world. The Intelligent Shift Control Actuator, an electric-hydraulic actuator that automatically executes clutch and shift actions, enables the user to experience the futuristic two-pedal technology. To unify the functioning components, Auto Gear Shift integrates the actuator and controller and directly attaches them in the gearbox.
This allows for coordinated management of the clutch, shifting, and engine for smoother gear changes, as well as combining the benefits of manual and automatic transmissions. When accelerating and decelerating, the next generation CVT technology delivers smooth performance with no shifts or shocks.
CVT, or Continuously Variable Transmission, provides infinite gear ratios, resulting in improved drivability and superior fuel economy. IMT offers a complete clutch-free manual gearbox with no clutch pedal, which is one of the most recent advancements in automatic vehicles.
IMT detects a gear shift and automatically engages your clutch using automated sensors and actuators. IMT is suited for those who want the convenience of a fully automated vehicle. Dual-clutch transmission, often known as the direct shift gearbox (or DSG), is undoubtedly among the most sophisticated automated automobile technology available today.
DCT primarily employs a twin-clutch mechanism, which is in charge of seamless gear changes. Automatic vehicles utilise either dry clutches (for DCT) or wet clutches based on engine torque (for DSG).
Tires are the heart and soul to operational mechanism of the EV at all times throughout its life that contributes to being the least expensive conglomerate part onboard the vehicle. The EVs tyres need to be technologically advanced and better modified through various requirements being fulfilled at all times.
The additional weight of any batteries and electric motor is offset by increasing the load-bearing capacity of the tire carcass, as indicated on most tires by an XL symbol on the sidewall. Energy losses due to tires are of particular concern to EV manufacturers. With rolling resistance accounting for up to 20% of a vehicle’s energy consumption.
WABCO is part of the latest intelligent transmission which are being planned under integration within the commercial vehicles segment. The Intelligent Automation releases drivers from constant clutch and shift operations through automated, optimized gear shifting, which offers additional benefits like improved fuel efficiency, longer component lifetime, and increased safety.
It is planned under the light, medium and heavy-duty commercial vehicles. The solution is a cost-effective solution from small to large volume applications. The system automates and optimizes gear shifting in 5-18 speed manual transmissions for light, medium and heavy-duty commercial vehicles. The intelligent approach helps to increase safety by interacting with other control systems like ABS or ESC.
