GENERAL DESCRIPTION
TSB Revision
AUTOMATIC TRANSMISSION
23A-7
ADAPTIVE SHIFT CONTROL
1. The computer learns the driving habits and pref-
erences of each individual driver by processing
driving data on engine output, tire load, foot brake
operation, etc. It then uses this data to adjust shift
timing to best suit the driver's style.
2. If the computer determines from the driving pat-
terns that the driver is one who enjoys a relaxed,
unhurried style, it adjusts timing to execute
up-shifts at a lower engine speed to provide a
smooth, quiet ride. On the other hand, if the com-
puter determines the driver to prefer a sporty ride,
it adjusts timing to shift up at a higher engine
speed to provide more powerful response.
3. If the computer determines that the driver tends
to apply the brakes often on a descending road-
way, it adjusts timing to down shift sooner so that
engine braking is more effectively applied. Con-
versely, if the computer determines that the driver
does not brake much while driving downhill, it
delays downshifting to minimize the effect of
engine braking.
