What is the Function of an Electronically Controlled Automatic Transmission?
1 Answers
The function of an electronically controlled automatic transmission is to select the optimal gear ratio for different loads and vehicle speeds, ensuring the engine operates at a corresponding stable speed. All gear shifts are performed automatically by the transmission, with the driver only needing to use the accelerator pedal to indicate their intent for speed changes and the gear selector to choose the desired operating mode. The electronically controlled automatic transmission is developed by adding an electronic control system to the traditional hydraulic automatic transmission. Common types of automotive automatic transmissions include: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch automatic transmission.
