1. A method of alerting a vehicle operator of an undesirable wheel component condition, comprising:
- a) measuring a temperature of a wheel component;
b) comparing the temperature of the wheel component with a known threshold temperature;
c) measuring a time period that the wheel component temperature exceeds the known threshold temperature;
d) comparing the measured time period with a known soak time; and
, e) providing a signal to an operator of the vehicle indicating an undesirable condition when the temperature of the wheel component has exceeded the known threshold temperature for longer than the known soak time.

Abstract
A monitoring and information system for a vehicle'"'"'s brakes and tires. The system includes one or more position sensors and/or temperature sensors that are used to measure parameters of the vehicles brakes and tires. The measured parameters are compared to known threshold parameters with one or more comparators. When one of the measured parameters is outside the limits of one of the threshold parameters, the system provides a signal indicating that an undesirable condition exists on one of the vehicles brakes or tires and provides information about the undesirable condition.

9. An apparatus for indicating a condition of a vehicle wheel assembly comprising:
-
a) a sensor coupled to said assembly for measuring a temperature of a wheel assembly component;
b) a first comparator for comparing a measured temperature of the component to a known threshold temperature;
c) a timer for measuring a time period the measured temperature exceeds said known threshold temperature;
d) a second comparator for comparing the measured time period to a known soak time; and
e) an indicator in communication with said first and second comparators for indicating wheel assembly conditions determined by comparing the measured temperature and measured time to the known threshold temperature and soak time. - View Dependent Claims (10, 11, 12)
