Introduction to ATC
An automatic transmission system used in automobiles which adapts to:
The Difference
Electronically Controlled Automatic Transmission
Adaptive Transmission Control
Recognition Elements
Driver-Type Recognition
Environmental Recognition
Driving-Situation Recognition
Driver-Type Recognition
Tracks how the driver has been “behaving” over the past few seconds
Environmental Recognition
Detects any increase in driving resistance like climbing or descending a mountain or decrease in traction
Driving-Situation Recognition
Monitors the throttle openings, road speeds and “g” level
