TM-282 < SYSTEM DESCRIPTION > [CVT: RE0F11A] SYSTEM LINE PRESSURE CONTROL : System Description INFOID:0000000009268088 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.
