CVT CONTROL SYSTEM : Protection Control 

INFOID:0000000009019613

The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and

transmission is lost. It automatically returns to the normal status if the safety is secured.

The TCM has the following protection control.

CONTROL FOR WHEEL SPIN

CONTROL WHEN FLUID TEMPERATURE IS HIGH

TORQUE IS REDUCED WHEN DRIVING WITH THE REVERSE GEAR

REVERSE PROHIBIT CONTROL

LINE PRESSURE CONTROL

Control

When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased. 
At the 1GR, the clutch pressure is increased. 

Vehicle behavior in 
control 

If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to 
a certain degree. From the 1GR, upshift to a certain gear ratio is only allowed. 

Normal return condi-
tion

Wheel spin convergence returns the control to the normal control.

Control

When the CVT fluid temperature is high, the gear shift permission maximum revolution and the maximum 
torque are reduced than usual to prevent increase of the oil temperature. 

Vehicle behavior in 
control 

Power performance may be lowered, compared to normal control.

Normal return condi-
tion

The control returns to the normal control when CVT fluid temperature is lowered.

Control

Engine output is controlled according to a vehicle speed while reversing the vehicle.

Vehicle behavior in 
control 

Power performance may be lowered while reversing the vehicle.

Normal return condi-
tion

Torque returns to normal by positioning the selector lever in a range other than “R” position.

Control

The reverse brake is controlled to avoid becoming engaged when the selector lever is set in “R” position while 
driving in forward direction at more than the specified speed.

Vehicle behavior in 
control 

If the selector lever is put at “R” position when driving with the forward gear, the gear becomes neutral, not 
reverse. 

Normal return condi-
tion

The control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes 
engaged.)

LINE PRESSURE CONTROL : System Description

INFOID:0000000009019614

SYSTEM DIAGRAM

DESCRIPTION

Highly accurate line pressure control (secondary pressure control) reduces friction for improvement of fuel

economy. 

Normal Oil Pressure Control

Appropriate line pressure and secondary pressure suitable for driving condition are determined based on the

accelerator pedal position, engine speed, primary pulley (input) speed, secondary pulley (output) speed, vehi-

cle speed, input torque, stop lamp switch signal, transmission range switch signal, lock-up signal, power volt-

age, target shift ratio, oil temperature and oil pressure. 

Secondary Pressure Feedback Control

In normal oil pressure control and oil pressure control in shifting, highly accurate secondary pressure is deter-

mined by detecting the secondary pressure using a oil pressure sensor and by feedback control.

SHIFT CONTROL : System Description

INFOID:0000000009019615

SYSTEM DIAGRAM

DESCRIPTION

To select the gear ratio that can give the driving force to meet driver's intent or vehicle situation, the vehicle

driving condition such as vehicle speed or accelerator pedal position is detected and the most appropriate

gear ratio is selected and the shifting method before reaching the speed is determined.   The information is

output to the primary pressure solenoid valve to control the line pressure input/output to the primary pulley, to

determine the primary pulley (movable pulley) position and to control the gear position.
