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 pro-

vides 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
preferences 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 control technologies with an innova-

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