ELECTRONICALLY-CONTROLLED 
SYSTEM

.

INVECS-III CONTROL

INVECS-III has been newly developed based on 
INVECS-II utilizing continuous variable characteris-
tics of CVT.

To select the pulley ratio which can provide the driv-
ing force corresponding to the driver's intention and 
vehicle conditions, TCM selects the optimal pulley 
ratio and determines the shift strategy to obtain it by 
detecting the vehicle driving conditions such as the 

vehicle speed, accelerator angle. Then, it outputs the 
command to the stepper motor, controls in/out flow of 
the line pressure to/from the primary pulley, positions 
the movable pulley of the primary pulley, and controls 
the gear ratio.

.

ENGINE BRAKE FEATURE ON THE 
DESCENDING SLOPE

Pulley ratio is controlled to obtain the engine brake 
suitable for the driver’s feelings.

Engine brake learning feature on the descending slope

Learning compensation is made to meet the tastes of 
a driver by judging the amount of the engine brake 
from the application of the accelerator or the brake.

.

DRIVING FEATURE ON THE ASCENDING SLOPE

If the foot leaves the accelerator pedal during driving 
on the ascending slope (called lift foot), driving capa-
bility is secured by preventing excessive upshifting.
