Tire leak rate detection and notification system

A system for detection of a pressure leak rate in a tire, the tire supporting a vehicle, the system comprising:

• a sensor mounted on the tire for measuring a pressure of the tire;
• means for transmitting measured pressure data from the sensor to a processor;
• and
• the processor being configured to:
• receive a plurality of measured tire pressures;
• batch the plurality of measured tire pressures according to a batch commencing on a batch starting point;
• detect a changepoint in measured tire pressures with a changepoint detection module;
• add a current measured tire pressure to the batch in a storage queue when the detection module does not detect the changepoint;
• calculate a leak rate for the batch with a leak rate determination module when the storage queue reaches a predetermined size;
• compare the leak rate to a predetermined threshold with a comparison module;
• issue an alert with an alert module when the leak rate crosses the predetermined threshold;
• and
• transmit the alert to at least one of a vehicle control system and a display device for actuation of the vehicle in response to the alert.
