Abstract
The present invention comprises and system and method for detecting a change in the state of pneumatic tires. The change of state refers to the state of internal air pressure, temperature or other such parameter. Herein, a difference of at least two successive readings are taken or a further analysis is performed and either is compared with a threshold value below which a change of state has occurred.
Claims24
A method for detecting at least one tire's change of state, comprising the steps of:
- repeatedly measuring characteristics of said tire;
- determining a first value comprising addition of a first and second measured characteristics, said first measured characteristic being taken at a preselect time, said second measured characteristic being taken at a time before said preselect time and further being multiplied by a preselected parameter;
- determining a second value comprising said first value less said second measured characteristic;
- and
- generating a comparison of between said successive second values and a predetermined threshold value, said comparison being indicative of said tire's change of state when said second value falls below said threshold.
A method for detecting at least one tire's change of state, comprising the steps of:
- repeatedly measuring characteristics of said tire;
- determining a first value comprising addition of a first and second measured characteristics, said first measured characteristic being taken at a preselect time, said second measured characteristic being taken at a time before said preselect time and further being multiplied by a preselected parameter;
- determining a second value comprising said first value less said second measured characteristic;
- and
- generating a comparison of a difference of said first and second values with a predetermined threshold value, said comparison being indicative of said tire's change of state.
A system for monitoring change of state of at least one tire, comprising means for:
- repeatedly measuring characteristics of said tire;
- determining a first value comprising addition of a first and second measured characteristics, said first measured characteristic being taken at a preselect time, said second measured characteristic being taken at a time before said preselect time and further being multiplied by a preselected parameter;
- determining a second value comprising said first value less said second measured characteristic;
- and
- generating a comparison of between said second value and a predetermined threshold value, said comparison being indicative of said tire's change of state when said second value falls below said threshold.
A system for monitoring change of state of at least one tire, comprising means for:
- repeatedly measuring characteristics of said tire;
- determining a first value comprising addition of a first and second measured characteristics, said first measured characteristic being taken at a preselect time, said second measured characteristic being taken at a time before said preselect time and further being multiplied by a preselected parameter;
- determining a second value comprising said first value less said second measured characteristic;
- and
- generating a comparison of a difference of said first and second values with a predetermined threshold value, said comparison being indicative of said tire's change of state.
The system according to claim 20, wherein said parameter is a constant.
