Description and operation
| Description |
The AWD ECU distributes the driving force to the front/rear wheel through controlling
the multi plate clutch on the AWD transfer case by analyzing the input information,
i.e. the wheel speed, accelerator and steering angle depending on the road condition
and driving state. The AWD vehicle has different power transmitting conditions
depending on the driving/road conditions. The vehicle speed is transmitted through
CAN communication from ABS/ESP ECU.
The information from the CAN communication includes the APS which indicates
the driver’s intention of acceleration, engine torque, ABS/ESP operation signal
and gear position. The AWD ECU controls the BLDC motor, warning lamp and indicating
lamp and communicates with the tester equipment. When a vehicle runs at normal
speed higher than 60KPH on regular roads, it is controlled under the 2WD conditions.
The ECU decides the driving force on the front and rear wheel by receiving the
signals from all sensors depending on the driving conditions, i.e. abrupt starting,
turning and driving on the low friction road, and the optimized torque which
is proper to the driving condition is transmitted to the front wheel through
calculating and controlling the transmitted torque data.

Description
The friction material inside the coupling will degrade over time. Therefore,
corresponding compensation values must be referenced and entered after replacing
the controller or the coupling...
