Theory Of Operation

The TVM module receives over the CAN line: 

• From the CDCM, the request for torque distribution
• From the ABS module, lateral acceleration data, the activation status of the ESC/ASR function and wheel rpm
• From the EPS, the steering wheel angle
• From the PCM, the accelerator pedal position and engine rpm
• From the BCM, the ignition status

The TVM module transmits via the CAN line: 

• To the CDCM, the status of the small electric motors and confirmation of torque distribution
• Data on its own operational status and torque implemented

The TVM module receives information directly from the: 

• Small electric motor temperature sensors
• Small electric motor position sensors
• Clutch oil temperature sensors

The TVM module sends activation commands directly: 

• To the two small electric motors

TVM Initialization procedure 

For each Key On, the TVM needs to know the reference point of the small electric motors (the "zero").

For each Key On, the TVM commands, at the same instant, the small electric motors and controls the implementation time of the demand for current and the signals from the position sensors.
