An automatic transmission (automatic transmission) adapts to driving style by adjusting gear shift parameters and torque converter locking torque.
Adaptation process:
1. Data acquisition: The automatic transmission records driving style data such as speed, acceleration, gear shift frequency and transmission temperature.
2. Data analysis: The automatic transmission ECU analyzes the data and identifies patterns in the driver’s driving style.
3. Parameter Setting: The ECU then adjusts the automatic transmission parameters to optimize gear shifting according to the driver’s driving style. For example:
– Aggressive driving: Earlier and more frequent gear changes for improved acceleration.
– Quiet Ride: Later and smoother gear changes for improved fuel economy and comfort.
– Rough terrain: Shifts faster when the load increases to maintain torque.
4. Updating parameters: Adjusted parameters are constantly updated and refined as the automatic transmission continues to collect data about the driver’s driving style.
How drivers can influence automatic transmission adaptation:
* By changing driving style: By accelerating more or less aggressively and shifting manually (if possible), drivers can train the automatic transmission to adapt to their individual preferences.
* Adaptation reset: Some automatic transmissions have an adaptation reset function that removes previously learned driving habits. This may be useful if the car has been driven by other drivers for a long time or if the driver’s driving style has changed.
Advantages of automatic transmission adaptation:
* Optimized fuel efficiency
* Improved acceleration and performance
* Increased driving comfort
* Extending the life of the automatic transmission by preventing unwanted gear changes
