an integrated control module mounted to the case, the integrated control module including:
a first power conversion device configured to drive the vehicle driving motor; and
a second power conversion device configured to drive the vehicle interior air conditioning compressor,
wherein the first power conversion device and the second power conversion device are integrated into the integrated control module,
wherein the first power conversion device has a number of phases, and
wherein the first power conversion device includes a same number of boards to correspond to a phase shift of the respective phases.

2. The driving module for a vehicle according to claim 1 , wherein the integrated control module further includes a third power conversion device configured to charge a high voltage battery of the vehicle.

3. The driving module for a vehicle according to claim 2 , wherein the integrated control module further includes a fourth power conversion device configured to charge a low voltage battery of the vehicle with electrical energy from the high voltage battery of the vehicle.

4. The driving module for a vehicle according to claim 3 , wherein the third power conversion device includes a power conversion circuit unit connected to at least one of the first power conversion device, the second power conversion device and the fourth power conversion device, and
wherein the power conversion circuit unit is usable during driving of the vehicle.

5. The driving module for a vehicle according to claim 4 , wherein the third power conversion device is configured to charge the high voltage battery when in a first mode, and is configured to deliver power for functions other than charging of the high voltage battery when in a second mode.

6. The driving module for a vehicle according to claim 4 , wherein the third power conversion device is configured to operate with any one of the first power conversion device, the second power conversion device and the fourth power conversion device when the third power conversion device is not being utilized to charge the high voltage battery.

7. The driving module for a vehicle according to claim 4 , wherein the power conversion circuit unit of the third power conversion device is connected to the fourth power conversion device.

8. The driving module for a vehicle according to claim 3 , wherein at least one of the first power conversion device, the second power conversion device and the fourth power conversion device is disposed adjacent to the third power conversion device.

9. The driving module for a vehicle according to claim 3 , further comprising a cooling module,
