Tire condition advisory system with optimum, advisory and warning states
First Claim
1. A tire pressure optimization system for a vehicle, comprising:
- a display; and
a controller in communication with the display, the controller programmed to;
receive inflation pressure information indicative of a vehicle tire'"'"'s inflation pressure,identify an operating state of the vehicle as being;
in an optimum state when the inflation pressure information indicates the inflation pressure is within an optimum pressure range, the optimum pressure range indicative of one or more optimum performance characteristics,in a warning state when the inflation pressure information indicates the inflation pressure is above a warning high pressure threshold or below a warning low pressure threshold, orin an advisory state when the inflation pressure information indicates the inflation pressure is within an advisory pressure range, the advisory pressure range indicative of an undesirable performance characteristic and outside of the warning state and the optimum state, andoperate the display to output;
an optimum state indication when the operating state is in the optimum state, the optimum state indication including a description of at least one of the one or more optimum performance characteristics,a warning indication when the operating state is in the warning state, andan advisory indication when the operating state is in the advisory state.

Abstract
A display and a controller are used to implement a tire pressure optimization system for a vehicle. The controller is programmed to receive inflation pressure information indicative of a vehicle tire'"'"'s inflation pressure, and identify an operating state of the vehicle as being in an optimum state when the inflation pressure information indicates optimum performance, in a warning state when the inflation pressure information indicates the inflation pressure is beyond a warning pressure threshold, or in an advisory state when the inflation pressure information indicates an undesirable performance characteristic outside of the warning state and the optimum state. The controller is programmed to 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.

7. A vehicle, comprising:
-
a tire; a device for detecting the tire'"'"'s inflation pressure and communicating inflation pressure information indicative of the tire'"'"'s inflation pressure; a display; and a controller in communication with the device and the display, the controller programmed to; identify an operating state of the vehicle as being; in an optimum state when the inflation pressure information indicates the inflation pressure is within an optimum pressure range, the optimum pressure range indicative of optimum performance, in a warning state when the inflation pressure information indicates the inflation pressure is above a warning high pressure threshold or below a warning low pressure threshold, or in an advisory state when the inflation pressure information indicates the inflation pressure is within an advisory pressure range, the advisory pressure range indicative of an undesirable performance characteristic and outside of the warning state and the optimum state, 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, the advisory indication including a directional instruction for adjusting the inflation pressure up or down to change the operating state from the advisory state to the optimum state. - View Dependent Claims (8, 9, 10, 11)

12. A vehicle, comprising:
-
a plurality of tires; a plurality of devices for detecting inflation pressure, each device being associated with one of the plurality of tires, detecting the associated tire'"'"'s inflation pressure, and communicating inflation pressure information indicative of the associated tire'"'"'s inflation pressure, a display; and a controller in communication with the plurality of devices and the display, the controller programmed to; calculate a pressure differential using inflation pressure information from two of the plurality of tires; identify an operating state of the vehicle as being; in an optimum state when the pressure differential indicates optimum performance and is less than an optimum pressure differential, or in an advisory state when the pressure differential indicates an undesirable performance characteristic and 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, and an advisory indication when the operating state is in the advisory state. - View Dependent Claims (13, 14, 15, 16, 17)
