INVECS-III Control
INVECS-III has been newly developed based on INVECS-II utilizing continuous variable characteristics of CVT.
To select the pulley ratio which can provide the driving 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.
