CVT control system : Component Description
*: With Nissan Dynamic Control System
CVT control system : TCM
The vehicle driving status is judged based on the signals from the sensors, switches, and other control units, and the optimal transaxle control is performed.
For TCM control items, refer to TM-329, "CVT CONTROL SYSTEM : System Description".
System : System Description".
The transmission range switch is installed to upper part of transaxle case.
The transmission range switch detects the selector lever position.
CVT control system : Primary Speed Sensor
The primary speed sensor is installed to side cover of transaxle.
The primary speed sensor detects primary pulley speed.
The primary speed sensor generates the ON-OFF pulse (short waveform) in proportion to the rotating body speed which is The higher the rotating body speed is, the faster the change cycle is. The TCM judges the rotating speed from the changing cycle of this pulse signal.
CVT control system : Secondary Speed Sensor
The secondary speed sensor is installed to side cover of transaxle.
The secondary speed sensor detects secondary pulley speed.
The secondary speed sensor generates the ON-OFF pulse (short waveform) in proportion to the rotating body speed which is The higher the rotating body speed is, the faster the change cycle is. The TCM judges the rotating speed from the changing cycle of this pulse signal.
CVT control system : Output Speed Sensor
The output speed sensor is installed to the back side of transaxle case.
The output speed sensor detects final gear speed. TCM evaluates the vehicle speed from the final gear revolution.
The output speed sensor generates the ON-OFF pulse (short waveform) in proportion to the rotating body speed which is The higher the rotating body speed is, the faster the change cycle is. The TCM judges the rotating speed from the changing cycle of this pulse signal.
CVT control system : CVT Fluid Temperature Sensor
The CVT fluid temperature sensor is installed to control valve.
The CVT fluid temperature sensor detects CVT fluid temperature in oil pan.
The fluid temperature sensor uses a thermistor, and changes the signal voltage by converting changes in the CVT fluid temperature to a resistance value. TCM evaluates the CVT fluid temperature from the signal voltage value.
CVT control system : Secondary Pressure Sensor
The secondary pressure sensor is installed to control valve.
The secondary pressure sensor detects the pressure applied to the secondary pulley.
When pressure is applied to the ceramic device in the secondary pressure sensor, the ceramic device is deformed, resulting in voltage change. TCM evaluates the secondary pressure from its voltage change. Voltage is increased along with pressure increase.
CVT control system : Primary Pressure Solenoid Valve
The primary pressure solenoid valve is installed to control valve.
The primary pressure solenoid valve controls the primary pressure control valve. For information about the primary pressure control valve, refer to TM-325, "TRANSAXLE : Component Description".
The primary pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].
NOTE
:
The principle of the linear solenoid valve utilizes the fact that the force
pressing on the valve spool installed
inside the coil increases nearly in proportion to the current. This allows it to
produce a fluid pressure that is
proportional to this pressing force.
The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT control system : Low Brake Solenoid Valv
The low brake solenoid valve is installed to control valve.
The low brake solenoid valve adjusts the tightening pressure of the low brake.
The low brake solenoid valve uses the linear solenoid valve [N/L (normal low) type].
NOTE
:
The principle of the linear solenoid valve utilizes the fact that the force
pressing on the valve spool installed
inside the coil increases nearly in proportion to the current. This allows it to
produce a fluid pressure that is
proportional to this pressing force.
The N/L (normal low) type does not produce hydraulic control when the coil is not energized.
CVT control system : High Clutch & Reverse Brake Solenoid Valve
The high clutch & reverse brake solenoid valve is installed to control valve.
The high clutch & reverse brake solenoid valve adjusts the tightening pressure of the high clutch and reverse brake.
The high clutch & reverse brake solenoid valve uses the linear solenoid valve [N/H (normal high) type].
NOTE
:
The principle of the linear solenoid valve utilizes the fact that the force
pressing on the valve spool installed
inside the coil increases nearly in proportion to the current. This allows it to
produce a fluid pressure that is
proportional to this pressing force.
The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT control system : Torque Converter Clutch Solenoid Valve
The torque converter clutch solenoid valve is installed to control valve.
The torque converter clutch solenoid valve controls the torque converter clutch control valve. For information about the torque converter clutch control valve, refer to TM-325, "TRANSAXLE : Component Description".
The torque converter clutch solenoid valve utilizes a linear solenoid valve [N/L (normal low) type].
NOTE
:
The principle of the linear solenoid valve utilizes the fact that the force
pressing on the valve spool installed
inside the coil increases nearly in proportion to the current. This allows it to
produce a fluid pressure that is
proportional to this pressing force.
The N/L (normal low) type does not produce hydraulic control when the coil is not energized.
CVT control system : Line Pressure Solenoid Valv
The line pressure solenoid valve is installed to control valve.
The line pressure solenoid valve controls the pressure regulator valve. For information about the pressure regulator valve, refer to TM-325, "TRANSAXLE : Component Description".
The line pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].
NOTE
:
The principle of the linear solenoid valve utilizes the fact that the force
pressing on the valve spool installed
inside the coil increases nearly in proportion to the current. This allows it to
produce a fluid pressure that is
proportional to this pressing force.
The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT control system : G Sensor
G sensor is installed to floor under instrument lower cover.
G sensor detects front/rear G and inclination applied to the vehicle.
G sensor converts front/rear G and inclination applied to the vehicle to voltage signal. TCM evaluates front/ rear G and inclination angle of the vehicle from the voltage signal.
CVT control system : S Mode Switch
The S mode switch is installed to the selector lever knob.
When the S mode indicator on the combination meter is OFF and the S mode switch is pressed, the S mode is active and the S mode indicator is ON.
When the S mode indicator on the combination meter is ON and the S mode switch is pressed, the S mode is cancelled and the S mode indicator is OFF.
CVT control system : S Mode Indicator
S mode indicator is positioned on the combination meter.
The S mode indicator is ON when set to the S mode.
S mode indicator turns on for a certain period of time when the ignition switch turns ON, and then turns off.
CVT control system : Shift Position Indica
TCM transmits shift position signal to combination meter via CAN communication. The actual shift position is displayed on combination meter according to the signal.
