In a controller of a vehicle drive unit that is one embodiment of the present invention, a plurality of slippage control regions (regions A to C) are set based on the timing of booming noise generation that accompanies engine driving (time from when the vehicle running state enters a region until booming noise is generated) so as to actively use, for example, regions B and C where booming noise is generated if the road load comes to a balance due to a slope or the like and running is then continued and where booming noise is not immediately generated even after the vehicle running state enters the regions, so the frequency of performing lockup slippage control is increased and the fuel saving effects of the lockup slippage control are enhanced.
