DESCRIPTION

Highly accurate line pressure control and secondary pressure control reduces friction for improvement of fuel economy.
Normal Oil Pressure Control
Revision: March 20122013 Infiniti JX
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, input torque, stop lamp switch signal, transmission range switch signal, lock-up signal, power voltage, 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 determined by detecting the secondary pressure using an oil pressure sensor and by feedback control.
