ADVANGATES
Enhanced Vehicle Dynamics
- Improved dynamics during acceleration and deceleration
Rapid activation

and deactivation
Fully controllable torque transfer characteristics
Enhanced Vehicle Driving Comfort and Transparency
No wind-up during tight cornering and parking
Optimal traction during acceleration
Enhanced Vehicle System Compatibility
- On-line communication with the CAN system
Better Fuel Consumption
- Compared with 4WD

Слайд 3

Variable Torque Control
At Parking: Low or zero torque transfer (for

easy and comfortable maneuverability)
Acceleration: High torque transfer for maximum traction
High speed driving: Reduced torque transfer, to minimum
Driving on slippery/wet roads: Swift activation of the coupling (for maximum traction and safety depending on the slip of the wheels)
ABS: Immediate deactivation on ABS signal
ESP/TCS: Normal torque control on ESP/TCS signal
Off-road: Rapid activation with high torque transfer for maximum traction

STEERING ANGLE SENSOR (Without ESP)
Application
- Location: Inside steering wheel
- Calculate

the steering amount and direction
- 3 Input Signals (ST 1, ST 2, ST N)
ST N detects the neutral position of steering wheel
Output voltage :1.3≤VOL ≤2.0V, 3.0≤VOH ≤4.1V

If ESP is adopted, SAS data is shared from ESP through Can communication.

OUTPUT SIGNAL
STEERING ANGLE SENSOR

Слайд 21

ACTIVE WHEEL SPEED SENSOR
Type: Hall Effect
Components: HALL IC,

Capacitor, Magnet
Output signal: Digital (Open Collector Type circuit integrated)
Good characteristics against temperature variation and noise
Low RPM Detection: 0 RPM can be detected
Air gap sensitivity: stable output pulse width against air-gap change
Supplying power: DC 12V

Слайд 22

4WD LOCK SWITCH
[When ‘4WD LOCK’ is selected]
EMC output signal
This switch

is selected 4WD LOCK lamp comes on. The ITMCM applies maximum current to the EMC resulting in 50 to 50 torque distribution.

Слайд 23

Is there any speed limitation with ‘4WD LOCK’ mode?
?Yes,there

is.
The maximum current flows until 35 km/h.
When the vehicle speed is over 35 km/h, ITMCM controls the EMC current on the duty basis. Even so, ‘4WD LOCK’ lamp still remains on at the moment. When the vehicle speed comes down under 35km/h, the EMC current comes back to the battery voltage.
Is the ESP operation available at the ‘4WD LOCK’ mode? ? Yes, ESP function operates as normal.

Слайд 24

EMC (Electro Magnetic Clutch)
The ITMCM varies the applied current to

the EMC to make a torque distribution to the rear wheels.
The EMC current increases then the magnetic force increases. Stronger magnetic force results in higher pressing force to secondary clutch.
