1. A pneumatic tire internal pressure control device for a vehicle, comprising:
- pneumatic tires each having a plurality of air chambers disposed therein along a tread width direction;
an internal pressure controller configured to control internal pressures of the plurality of air chambers; and
an instruction unit configured to give the internal pressure controller an instruction to change the internal pressures on the basis of a running state of the vehicle,whereinthe instruction unit gives the internal pressure controller the instruction on the basis of a state where the vehicle is being displaced in a leftward or rightward direction,the instruction unit includes a running lane maintenance monitoring unit configured to monitor whether or not the vehicle is running within a predetermined running lane, andthe instruction unit gives the internal pressure controller the instruction on the basis of a monitoring by the running lane maintenance monitoring unit.
