ELECTRONICALLY-CONTROLLED SYSTEM

.

INVECS-II

• When in drive ("D" range), the new automatic transmission

employs an innovative shift schedule to provide a high level
of comfort and "easy driving style" that matches all driving
conditions as well as the driver's driving style.

• INVECS-II features "Optimum Shift Control", which provides

shift timing the average driver perceives to be the optimum
timing under any road conditions. "Adaptive Shift Control"
adjusts shift timing to match the driving habits and prefer-
ences of individual drivers.

.

FEATURES

OPTIMUM SHIFT CONTROL

1. The shift patterns found satisfying by the typical driver for all

ranges of driving are stored in the computer's memory. The
computer uses this data to analyze road conditions and the
driver's style of operation, and then outputs the optimal shift
patterns stored in its memory to best match the conditions.

2. We introduce the latest in control technologies with an inno-

vative new algorithm called the "neutral network" that works
to imitate the decision-making processes of the human
brain. The neural network links a wide variety of input data
regarding road and operating conditions, and instantly
makes accurate shift control decisions.

.

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.
