Abstract
This disclosure describes systems and methods for determining tire inflation pressure loss. An example method may include receiving first tire pressure data for a first tire of a vehicle at a first time. The example method may also include receiving second tire pressure data for the first tire at a second time. The example method may also include identifying a slow leak in the first tire based on a relationship between the first tire pressure data and the second tire pressure data. The example method may also include causing to send an alert to a user.
Claims16
A system comprising:
- a processor;
- and
- a memory storing computer-executable instructions, that when executed by the processor, cause the processor to:
- receive first tire pressure data for a first tire of a vehicle at a first time;
- receive second tire pressure data for the first tire at a second time;
- adjust the first tire pressure data based on altitude data or temperature data;
- receive third tire pressure data and fourth tire pressure data for the first tire;
- determine that a first difference between the third tire pressure data and the fourth tire pressure data is greater than a first threshold amount;
- receive, subsequent to receiving the third tire pressure data, fifth tire pressure data for the first tire;
- determine a second difference between the fourth tire pressure data and the fifth tire pressure data;
- determine, based on the first difference and the second difference, that a rate at which air is leaving the first tire is a non-linear rate;
- determine, based on determining that the rate at which air is leaving the first tire is a non-linear rate, that the fifth tire pressure data indicates that an intentional change in tire pressure is occurring;
- filter out the fifth tire pressure data based on the determination that the fifth tire pressure data indicates that an intentional change in tire pressure is occurring such that the fifth tire pressure data is disregarded in determining whether a slow leak is occurring in the first tire;
- identify a slow leak in the first tire based on a relationship between the first tire pressure data and the second tire pressure data without considering the fifth tire pressure data;
- and
- cause to send an alert to a user indicating the slow leak.

A method comprising:
- receiving first tire pressure data for a first tire of a vehicle at a first time;
- receiving second tire pressure data for the first tire at a second time;
- adjusting the first tire pressure data based on one or more external factors, the one or more external factors including at least one of:
- an altitude or a temperature;
- receiving third tire pressure data and fourth tire pressure data for the first tire;
- determining that a first difference between the third tire pressure data and the fourth tire pressure data is greater than a first threshold amount;
- receiving, subsequent to receiving the third tire pressure data, fifth tire pressure data for the first tire;
- determining a second difference between the fourth tire pressure data and the fifth tire pressure data;
- determining, based on the first difference and the second difference, that a rate at which air is leaving the first tire is a non-linear rate;
- determine, based on determining that the rate at which air is leaving the first tire is a non-linear rate, that the fifth tire pressure data indicates that an intentional change in tire pressure is occurring;
- filtering out the fifth tire pressure data based on the determination that the fifth tire pressure data indicates that an intentional change in tire pressure is occurring such that the fifth tire pressure data is disregarded in determining whether a slow leak is occurring in the first tire;
- identifying a slow leak in the first tire based on a relationship between the first tire pressure data and the second tire pressure data without considering the fifth tire pressure data;
- and
- causing to send an alert to a user indicating the slow leak.

- determining that a first difference between the third tire pressure data and the fourth tire pressure data is greater than a first threshold amount;
- receiving, subsequent to receiving the third tire pressure data, fifth tire pressure data for the first tire;
- determining a second difference between the fourth tire pressure data and the fifth tire pressure data;
- determining, based on the first difference and the second difference, that a rate at which air is leaving the first tire is a non-linear rate;
- determining, based on determining that the rate at which air is leaving the first tire is a non-linear rate, that the fifth tire pressure data indicates that an intentional change in tire pressure is occurring;
- filtering out the fifth tire pressure data based on the determination that the fifth tire pressure data indicates that an intentional change in tire pressure is occurring such that the fifth tire pressure data is disregarded in determining whether a slow leak is occurring in the first tire;
- identifying a slow leak in the first tire based on a relationship between the first tire pressure data and the second tire pressure data and without considering the fifth tire pressure data;
- and
- causing to send an alert to a user indicating the slow leak.
