Control Of The Locking Torque For The Multi-Plate Clutch
Control of the locking torque for the multi-plate clutch in the transfer case allows the front axle to be coupled infinitely variably to the drive train. The input torque at the front axle can be increased or reduced in response to the road situation and conditions.
The DSC control unit calculates the locking torque for the multi-plate clutch as follows
- Pre-activation = driver's command
- Driving dynamic control
- Detection of different tyre rolling circumferences
Pre-Activation
Pre-activation reflects the driver's command and is used to calculate the required locking torque.
The evaluation criteria below are taken into account to in determining the driver's command
- Accelerator-Pedal Value
- Engine Torque
- Engine Speed
- Car Road Speed
- Gear Engaged
- Steering Angle
