Method for learning and setting warm placard pressure threshold for a direct tire pressure monitoring system

A method for setting a warm placard tire pressure threshold for a motor vehicle tire pressure monitoring system that initiates a learn mode in the tire pressure monitoring system, starts a timer upon determining a vehicle speed is greater than a predetermined speed threshold, stops the timer upon de...

Zusammenfassung:	A method for setting a warm placard tire pressure threshold for a motor vehicle tire pressure monitoring system that initiates a learn mode in the tire pressure monitoring system, starts a timer upon determining a vehicle speed is greater than a predetermined speed threshold, stops the timer upon determining the vehicle speed is less than or equal to the predetermined speed threshold or a predetermined period of time has expired, detects a plurality of tire pressures for a tire location while the timer is timing, stores the plurality of tire pressures, averages the plurality of tire pressures to determine a warm placard tire pressure threshold upon the predetermined period of time expiring, and sets the warm placard tire pressure threshold in the tire pressure monitoring system.
