Abstract
A method and apparatus for controlling inflation pressure of at least one pneumatic wheel on a machine is disclosed. This includes determining a ground speed or ground acceleration of the machine and determining a rotational velocity or rotational acceleration of a drivetrain for the machine as well as adjusting the inflation pressure in response to a relationship between the ground speed of the machine and the rotational velocity of the drivetrain for the machine or the ground acceleration of the machine and rotational acceleration of the drivetrain for the machine. The temperature of and weight load applied to pneumatic wheel can also be utilized in altering the inflation pressure of the pneumatic wheel. This data may be stored and inflation pressure of at least one pneumatic wheel may be controlled based on this previously stored data.
