Abstract
A method of monitoring the temperature of an axle includes the steps of reading temperatures from an axle of a vehicle, comparing the read temperatures with expected temperatures, and sending warning signals when necessary. A temperature sensor may be used to read temperatures of the axle and send temperature signals to a control to perform computations and compare the computations with expected temperatures. Furthermore, the control may send warning signals to a display to indicate that a problem may exist.
Claims11
A method of monitoring temperatures of an axle to determine if the axle is experiencing a problem, the method comprising:
- a. reading a plurality of temperatures of the axle taken over period of time;
- b. comparing said read temperatures with an expected temperature information of said axle wherein said expected temperature information includes a threshold temperature, a threshold number, a threshold mean temperature, a threshold standard deviation, a threshold moving average, and a threshold peak temperature of said axle;
- and
- c. if said read temperatures differ from said expected temperature, then indicating said axle is experiencing a problem.
A method of motoring temperatures of an axle to determine if the axle is experiencing a problem, the method comprising:
- a. reading a plurality of temperatures of the axle;
- b. counting the number of times a threshold temperature is reached by said read temperatures;
- comparing the number of times said threshold temperature is reached with a threshold number;
- if the number of times said threshold temperature is reached is greater than said threshold number, then setting a first warning;
- and
- c. if said read temperatures differ from an expected temperature information, then indicating said axle is experiencing a problem.
A method of monitoring temperatures of an axle to determine if the axle is experiencing a problem, the method comprising:
- a. reading a plurality of temperatures;
- b. comparing said read temperatures with an expected temperature information of said axle;
- and
- c. if said read temperatures differ from said expected temperature information, then determining a number of differences between said read temperatures and said expected temperature information, and indicating said axle is experiencing a problem which is a low oil problem or a physical damage problem;
- wherein said read temperatures are monitored and used to discriminate between the low oil problem and the physical damage problem.
