Automatic transmission (AT)
*Transmission type: Hydraulic
*Working principle: Using hydraulic transformer and planetary gears for smooth gear changes.
* Gear shifting: Automatic, carried out by a computer that takes into account vehicle speed, engine speed and load.
*Advantages: Smooth gear shifting, ease of use.
* Disadvantages: Lower efficiency than manual transmission, higher maintenance cost.
Robotic gearbox (manual transmission)
*Transmission type: Mechanical
* Operating principle: Using a manual transmission with automated clutch and gear shift control.
* Gear shifting: It is carried out by an electro-hydraulic drive, which is controlled by a computer.
* Advantages: Higher efficiency than automatic transmission, lower maintenance cost.
* Disadvantages: There are often delays when changing gears, jerks when changing gears at low speeds.
Key differences:
* Transmission type: Manual transmission has a mechanical transmission, and automatic transmission has a hydraulic transmission.
* Smooth gear shifting: Automatic transmission provides smoother gear shifting than manual transmission.
* Shift speed: Manual transmissions typically shift gears faster than automatic transmissions.
* Efficiency: Manual transmission usually has higher efficiency than automatic transmission.
* Maintenance cost: Automatic transmissions are usually more expensive to maintain than manual transmissions.
