Abstract
A pneumatic tires (20FL, 20FR, 20RL, 20RR) each having a plurality of air chambers disposed therein along a tread width direction. An internal pressure control device (100) includes a sensor unit (120) configured to inform a controller (110) that the four-wheel automobile (10) is going as being displaced in the leftward or rightward direction; and the controller (110) configure to change the internal pressures of the plurality of air chambers on the basis of the instruction outputted from the sensor unit (120).
Claims17
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,
- wherein
- the 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, and
- the instruction unit gives the internal pressure controller the instruction on the basis of a monitoring by the running lane maintenance monitoring unit.
A method for controlling internal pressures of pneumatic tires for a vehicle, the pneumatic tire having a plurality of air chambers disposed therein along a tread width direction, the method comprising the steps of:
- instructing that the vehicle is being displaced in a leftward or rightward direction;
- and
- changing internal pressures of the plurality of air chambers on the basis of the instruction in the instructing step,
- the method further comprising:
- monitoring whether or not the vehicle is running within a predetermined running lane, and
- changing the internal pressures of the plurality of air chambers on the basis of the monitoring of the vehicle.
