NOTE:
The gear ratio is set for every position separately.

System Description

INFOID:0000000000988623

In order to select the gear ratio which can obtain the driving force in accordance with driver's intention and the
vehicle condition, TCM monitors the driving conditions, such as the vehicle speed and the throttle position and
selects the optimum gear ratio, and determines the gear change steps to the gear ratio. Then send the com-
mand to the step motor, and control the flow-in/flow-out of line pressure from the primary pulley to determine
the position of the moving-pulley and control the gear ratio.

“D” POSITION

Shifting over all the ranges of gear ratios from the lowest to the high-
est.

“M” POSITION

When the selector lever is put in the manual shift gate side, the fixed
changing gear line is set. By moving the selector lever to + side or -
side, the manual mode switch is changed over, and shift change like
M/T becomes possible following the changing gear set line step by
step.

DOWNHILL ENGINE BRAKE CONTROL (AUTO ENGINE BRAKE CONTROL)

When downhill is detected with the accelerator pedal released, the engine brake will be strengthened up by
downshifting so as not to accelerate the vehicle more than necessary.

< FUNCTION DIAGNOSIS >

[CVT: RE0F10A]

According to vehicle speed and a change of accelerator pedal angle, driver's request for acceleration and driv-
ing scene are judged. This function assists improvement in acceleration feeling by making the engine speed
proportionate to the vehicle speed. And a shift map which can gain a larger driving force is available for com-
patibility of mileage with driveability.
