A robotic automatic transmission (also known as a robotic transmission or RMT) is a type of automatic transmission that uses an electro-hydraulic drive to change gears automatically.
Basic operating principles of RMT:
*Clutch: Like a conventional manual transmission, the RMT has a clutch that is used to decouple the engine and transmission when changing gears.
* Actuator: RMT uses an electro-hydraulic activator to control the clutch and gear shifting. The activator is driven by an electronic control unit (ECU).
* Electronic Control Unit (ECU): The ECU reads engine speed, vehicle speed, gas pedal position and other parameters and uses this information to determine the optimal gear shift point.
* Sensors: RMT uses a variety of sensors to collect vehicle health data such as gear selector position, vehicle speed and engine speed.
*Hydraulic Block: The hydraulic block uses pressurized oil to power the clutch and gear shift actuators.
Advantages of RMT:
* Convenience: RMT provides smooth and seamless gear shifting, eliminating the need to use the clutch pedal.
* Fuel Economy: Compared to traditional automatic transmissions, RMTs are often more fuel efficient because they reduce power loss during gear changes.
*Weight and Size: RMTs are typically lighter and more compact than traditional automatic transmissions.
*Dynamic Performance: Some RMTs offer manual shift modes, allowing drivers to have greater control over gear changes.
Disadvantages of RMT:
*Shift lag: RMT may have a slight lag when shifting gears, especially when downshifting.
*Cost: RMTs are typically more expensive than conventional manual or automatic transmissions.
* Reliability: RMTs may be less reliable than traditional manual transmissions, especially under severe operating conditions.
*Maintenance: RMTs require periodic maintenance such as oil and filter changes.
