Have you updated your maps in your car in this manner???

Yes how to update the sd card without a dealer, please share thanks in advance

Lots of folks have experienced this, but it makes me so happy every time:

In S and S+, when you hit the brakes hard in response to something unplanned or for an upcoming corner, the car downshifts and rev matches.
It then stays in that lower gear for many seconds, which aids in emergency braking if you need, or to return to the gas in the power band to accelerate through the turn or escape a situation.

It's just so well tuned and intuitive, automatic and seamless. Makes the car a blast to drive and improves its safety all at the same time.

for the most dramatic affect put it in Manual mode and drive the car hard for a while, rinse & repeat for 2-3 days on and off, and the transmission will relearn that you mean business, then you can really have fun!

How the transmission performs is not going to change.

Yes, it will change, not dramatically , but the transmission is a learning transmission, driving the card hard for a few days will make a difference. See page 6 of the attached PDF. You drive it hard and in sport+ it will adapt to your driving style and be more prone to downshift and hold gears longer than after several days of consistent driving.

Pretty much every modern transmission has some "learning" capability to adapt the car's shifting to how its driven; it isn't just valve-bodies anymore.


and this isn't even touching how the ECU and TCU interact, and what learning capability is built in between those two devices, let alone all the rest of the computers built in the car.

I did not see any mention or reference that the transmission has any ability whatsoever to 'learn' or to 'relearn' anything, based on previous driving characteristics or not, at any time - short-term or long-term. Obviously the transmission has very sophisticated controls inherently built into the transmission and the ECU which controls its performance and operation based on the driver's input. But, I do not believe the transmission's future operation or performance can change or is meant to change by driver influence relevant to how the car has previously been driven. In other words, I do not think the transmission or its ECU has the ability to learn or relearn anything from how the driver drives the car or how the driver makes the transmission shift.

CONTROL SYSTEM ARCHITECTURE
The powertrain control system features a newly developed driving response and acceleration management system. In this system, a Model Driver decides drive power targets based upon the accelerator operation, and a Powertrain Manager (PTM) sorts them into an engine torque target and gear stage target. As a result, both engine and transmission play an actuatorlike role, dutifully realizing each target. The PTM also considers requests for drive power from other systems such as Vehicle Dynamics Integrated Management (VDIM), which contribute to improvements in vehicle safety as well as performance. Figure 5 shows the main differences between this control system and conventional control systems.

Regarding the gear stage selection process during deceleration, the new powertrain control system achieves reduced operation frequency of the brake pedal by the driver and enhancement of reacceleration performance. This has been made possible by expanding both the Grade Logic and the Navigation based Artificial Intelligence (Navi-AI) shift control, which allow fine-tuned engine brake control. In other scenarios, when the driver exhibits sportier driving, acceleration and deceleration is enhanced by delaying upshifts to maintain higher engine speeds. Further, during t

DEVELOPMENT OF A SHIFT CONTROL SYSTEM (NAVIAI-SHIFT) FOR 5-SPEED AUTOMATIC TRANSMISSIONS USING INFORMATION FROM A VEHICLE NAVIGATION SYSTEM

The authors have developed a transmission control system called NAVIAI-SHIFT that controls 5-speed automatic transmissions by using road information from a navigation system. It has been in use in Toyota's new Mark II. This control system calculates the length and geometry of the street from the vehicle's current position to the next corner based on road information from the onboard navigation system. It then determines the optimum gear selection based on the above-mentioned information and road grade information, and associates the determination with the present running speed and driver's operating behavior so that the optimum gearshift control can be achieved. This paper describes the configuration, features and effect of the new automatic transmission control system that employs navigation information.


Sorry for the caps, just copy and pasting

I am firmly under the belief that the information you are referring to (above) comes from the inherent logic of the transmission and its controlling ECU (or powertrain control system) based on input from various sources, whether it comes from the brake pedal, the accelerator or logic of the car's grade angle. While the artificial intelligence is impressive it is not 'learning' or 'relearning' anything where the transmission's future performance is enhanced based on how the driver may drive the car or how he may make the transmission shift. The transmission's shift characteristics and performance is based on various parameters signaled to its control system in real time...and it reacts to that 'real time' input. It does not react to how the car has previously been driven, or what one may call archival or historical input that needs to be learned. The transmission's operation is not designed to 'learn' or 'relearn' anything. As a matter of fact, the transmission and its control system is far beyond the level of learning or relearning - it is operating at its highest zenith of effectiveness all the time (once normal operating temperatures and conditions are met).

You talkin like well visors? pics?

Edited. Good catch. But no not what you thought..
