Abstract
A tire pressure control system for a vehicle including a vehicle frame, at least one axle, a tire coupled to the axle, a tire pressure sensor sensing pressure in the tire, a load sensor sensing the load on the axle, a controller electronically coupled to the tire pressure sensor and the load sensor, and a compressor pneumatically coupled to the tire and controlled by the controller to maintain a desired tire pressure for the load.
Claims15
A tire pressure control system for a vehicle comprising:
- a vehicle frame;
- at least one axle;
- a tire coupled to said at least one axle;
- a tire pressure sensor sensing pressure in said tire;
- a load sensor sensing the load on said at least one axle;
- a controller electronically coupled to said tire pressure sensor and said load sensor;
- and
- a compressor pneumatically coupled to said tire and controlled by said controller to maintain a desired tire pressure for said load.
5 more elements
A method of controlling tire pressure in a tire comprising:
- monitoring tire pressure in the tire;
- monitoring load on the tire;
- determining a desired tire pressure from the monitored load;
- and
- generating said desired pressure in the tire.
