Abstract

Methods, systems, and computer program products for a wireless portable tire monitoring system are provided. According to one aspect, wireless portable tire monitoring system includes a portable monitor that receives sensor information from one or more tire-mounted sensors, each sensor being associated with a tire, and each tire being associated with a vehicle, and monitors tire status. Multiple vehicles may be monitored from the same portable monitor, and tires can be dynamically associated with or disassociated from a particular vehicle. Tire status may be displayed to the user in a manner that provides a graphic association between the tire status and the vehicle to which the tire is associated, including showing the location of the tire on the vehicle. The system may asynchronously alert the user if threshold conditions, such as low tire pressure, are detected.

Claims

1. A method of operation of a wireless portable tire monitoring system, the method comprising:

at a wireless portable tire monitor having at least one processor and a memory for storing sensor mappings and vehicle profiles;

receiving sensor information from one or more tire-mounted sensors, each sensor being associated with a tire according to a sensor mapping, and each tire and associated sensor being associated with a vehicle according to a vehicle profile; and

monitoring a status of at least one of the one or more tires.

2. The method of claim 1 wherein the sensor information is received from a plurality of vehicles according to each vehicle'"'"'s respective vehicle profile.

3. The method of claim 1 wherein each tire can be dynamically associated with or disassociated from a particular vehicle.

4. The method of claim 1 wherein receiving the sensor information comprises receiving at least one of:

an inflation pressure of the tire;

a temperature of the tire;

an indication of rotation of the tire; and

an indication of vibration of the tire.

5. The method of claim 1 wherein monitoring a status comprises making the tire status available for viewing by the user of the wireless portable tire monitoring system comprises providing a graphic association between the tire status and the vehicle with which the tire is associated and graphically representing a location or position of the tire on or relative to the vehicle.

6. The method of claim 1 wherein monitoring the status of the tire comprises:

determining whether the sensor information indicates a threshold condition, the threshold condition comprising that at least one of;

a tire pressure is above or below a pressure threshold;

a tire temperature is above or below a temperature threshold;

a tire rotation is above or below a rotation rate threshold; and

a tire vibration is above or below a vibration threshold; and

upon determination that the sensor information indicates the threshold condition, performing an action.

7. The method of claim 6 wherein performing an action comprises providing an alert or notification to a user of the wireless portable tire monitoring system.

8. A wireless portable tire monitor, comprising:

a wireless transceiver;

a display device;

one or more processors; and

memory storing instructions executable by the one or more processors, whereby the wireless portable tire monitor is operable to;

receive sensor information from one or more tire-mounted sensors, each sensor being associated with a tire according to a sensor mapping stored in memory, and each tire and associated sensor being associated with a vehicle according to a vehicle profile stored in memory; and

monitor a status of at least one of the one or more tires.

9. The wireless portable tire monitor of claim 8 wherein the sensor information is received from a plurality of vehicles according to each vehicle'"'"'s respective vehicle profile.

10. The wireless portable tire monitor of claim 8 wherein each tire can be dynamically associated with or disassociated from a particular vehicle.

11. The wireless portable tire monitor of claim 8 wherein receiving the sensor information comprises receiving at least one of:

an inflation pressure of the tire;

a temperature of the tire;

an indication of rotation of the tire; and

an indication of vibration of the tire.

12. The wireless portable tire monitor of claim 8 wherein monitoring the status comprises making the tire status available for viewing by the user of the wireless portable tire monitor comprises providing a graphic association between the tire status and the vehicle to which the tire is associated and graphically representing a location or position of the tire on or relative to the vehicle.

13. The wireless portable tire monitor of claim 8 wherein monitoring a status of the tire comprises:

determining whether the sensor information indicates a threshold condition, the threshold condition comprising that at least one of;

a tire pressure is above or below a pressure threshold;

a tire temperature is above or below a temperature threshold;

a tire rotation is above or below a rotation rate threshold; and

a tire vibration is above or below a vibration threshold; and

upon a determination that the sensor information indicates a threshold condition, performing an action.

14. The wireless portable tire monitor of claim 13 wherein performing an action comprises providing an alert or notification to a user of the wireless portable tire monitor.

15. A non-transitory computer readable medium storing software instructions that, when executed by one or more processors of a wireless portable tire monitor, cause the wireless portable tire monitor to:

receive sensor information from one or more tire-mounted sensors, each sensor being associated with a tire according to a sensor mapping stored in memory, and each tire and associated sensor being associated with a vehicle according to a vehicle profile stored in memory; and

monitor a status of at least one of the one or more tires.
