Automated Manual Transmission (AMT) in a Car: Meaning, Advantages & Disadvantages
Automated Manual Transmission or AMT in a car is a transmission type that removes the manual effort of shifting clutch and gear. Want to know more about automated manual transmission in a car? If yes, keep scrolling!
What Is AMT in a Car?
Automated Manual Transmission features a brake pedal and accelerator, and as mentioned above, it assists in automating the manual transmission by utilising automatic actuation to shift gear and clutch. A driver can manually shift gears as well by applying the gear lever forward to upshift and backwards to downshift a vehicle.
How Does an Automated Manual Transmission Work?
Automatic Manual Transmission employs ECU or Electronic Control Unit and hydraulics to propel a vehicle. The pre-programmed gear shift patterns data are saved in ECU, and it operates on the RPM range, which is already set from the factory. Once the mechanism assesses RPMs, the Electronic Control Unit uses actuators to operate the gearbox and clutch.
What Are the Advantages of Automated Manual Transmission in a Car?
1. Tackles Traffic Conveniently
This transmission type automates manual transmission, which removes the necessity to manually shift gears and clutch unless the driver opts for a manual gear shift. It is ideal for car drivers who regularly commute through traffic. Besides, the in-built 'Creep' allows a driver to release the brake pedal without using the accelerator to drive at lower speeds.
It offers optimum fuel efficiency, unlike other ATs, and is another attribute to select a car with automatic transmission. Individuals can find an automated manual transmission in hatchbacks, and manufacturers add optimum pre-programmed shift patterns to provide adequate mileage returns.
If an individual wishes to switch from automatic to a manual transmission, he or she can do the same with cars equipped with that feature. Besides, manual transmission in AMT-equipped cars has a bidirectional shift path, and no complications of the clutch make it easier.
It is affordable compared to other automatic gearboxes, as it is nearly half of the latter's price. At the same time, AMT gearboxes cost almost one-fourth of the price of DCT ones.
What Are the Disadvantages of Automated Manual Transmission in a Car?
1. Inconsistent Shifting of Gears
Individuals driving AMT-equipped cars may face inconsistency in shifting gears, and unlike other automatic transmissions, AMT offers an inferior gear shifting experience.
2. Limited Manoeuvrability
Automated Manual Transmission operates on the preset RPM range, leading to unplanned upshifts while overtaking. This can jeopardise one's on-road safety.
3. Unsuitable for Hilly Terrains
Driving a car with AMT on hilly terrain is inconvenient as a driver needs to shift to manual mode with frequent utilisation of brakes.
Thus, assess the working mechanism, advantages and disadvantages of an AMT in a car as mentioned above to make an informed decision before buying one.
