TIRE CONDITION ADVISORY SYSTEM
First Claim
1. A tire pressure optimization system for a vehicle, comprising:
- a pressure detection device for detecting a first vehicle tire'"'"'s inflation pressure;
a second pressure detection device for detecting a second vehicle tire'"'"'s inflation pressure;
a display; and
a controller in communication with the first and second pressure detection devices and the display, the controller programmed to;
calculate a pressure differential between the first vehicle tire'"'"'s inflation pressure and the second vehicle tire'"'"'s inflation pressure;
identify an operating state of the vehicle as being;
in a warning state when the first inflation pressure is below a warning low pressure threshold,in an optimum state when the first inflation pressure is within an optimum pressure range where the vehicle will exhibit optimum performance,in an advisory state when the first inflation pressure is within an advisory pressure range where the vehicle will exhibit an undesirable performance characteristic, wherein the advisory pressure range is outside of the optimum pressure range and above the warning low pressure threshold, andin the advisory state when the pressure differential is greater than an optimum pressure differential; and
operate the display to output an optimum state indication when the operating state is in the optimum state, a warning indication when the operating state is in the warning state, and an advisory indication when the operating state is in the advisory state.

Abstract
A pressure detection device and a controller in communication with the device are used to implement a tire pressure optimization system for a vehicle. The pressure detection device detects a vehicle tire'"'"'s inflation pressure. The controller is programmed to identify the vehicle as being in a warning state when the inflation pressure is below a warning low pressure threshold, identify the vehicle as being in an optimum state when the inflation pressure is within an optimum pressure range where the vehicle will exhibit optimum performance, and identify the vehicle as being in an advisory state when the inflation pressure is within an advisory pressure range where the vehicle will exhibit an undesirable performance characteristic. The advisory pressure range is outside of the optimum pressure range and above the warning low pressure threshold.
