JM 4WD Electronically Controlled On-Demand 4WD System

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

(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: Immediate deactivation on ESP/TCS signal
Off-road: Rapid activation with high torque transfer for maximum traction

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

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

resulting in 50 to 50 torque distribution.

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.
