Vehicle sensor system
A vehicle sensor system includes a fluid sensor configured to be disposed onboard a vehicle system and at least partially extend into a gearbox of a traction motor of the vehicle system. The fluid sensor is configured to output data representative of an amount of a lubricating fluid in the gearbox. The system also includes a positioning system configured to output data representative of movement or an absence of movement of the vehicle system, and one or more processors configured to determine the amount of the lubricating fluid in the gearbox based on the data that is output by the fluid sensor responsive to the data output by the positioning system indicating that the vehicle system has not moved or has moved by less than a designated distance for at least a designated, non-instantaneous period of time.
1. A system comprising:
one or more sensors configured to measure temperatures of different axles of a vehicle; and
one or more processors configured to obtain the temperatures that are measured and to compare the temperatures of the different axles for identifying a deteriorated condition of at least one of the axles;
wherein the one or more sensors are configured to measure the temperatures of the axles at different speeds of the vehicle, wherein the one or more processors are configured to identify the deteriorated condition of at least one of the axles responsive to the temperature of a first axle of the axles changing relative to the temperatures of at least a second axle of the axles not changing between the different speeds of the vehicle.
2. The system of claim 1 , wherein the one or more processors are configured to examine the temperatures to identify the deteriorated condition of the first axle responsive to the temperature of the first axle not decreasing between the different speeds of the vehicle while the temperature of at least the second axle decreases between the different speeds of the vehicle.
3. The system of claim 1 , wherein the one or more processors are configured to examine the temperatures to identify the deteriorated condition of the first axle responsive to the temperature of the first axle increasing between the different speeds of the vehicle while the temperature of at least the second axle does not decrease between the different speeds of the vehicle.
4. The system of claim 1 , wherein the vehicle is an automobile.
5. The system of claim 1 , wherein the one or more processors are configured to automatically control operation of the at least one axle responsive to identifying the deteriorated condition.
6. A method comprising:
measuring temperatures of different axles of a vehicle; and
identifying a deteriorated condition of at least one of the axles by comparing the temperatures of the different axles;
wherein the temperatures of the axles are measured at different speeds of the vehicle, wherein the deteriorated condition of at least one of the axles is identified responsive to the temperature of a first axle of the axles changing relative to the temperatures of at least a second axle of the axles not changing between the different speeds of the vehicle.
7. The method of claim 6 , wherein the deteriorated condition of the first axle is identified responsive to the temperature of the first axle not decreasing between the different speeds of the vehicle while the temperature of at least the second axle decreases between the different speeds of the vehicle.
8. The method of claim 6 , wherein the deteriorated condition of the first axle is identified responsive to the temperature of the first axle increasing between the different speeds of the vehicle while the temperature of at least the second axle does not decrease between the different speeds of the vehicle.
9. The method of claim 7 , further comprising automatically controlling operation of the at least one axle responsive to identifying the deteriorated condition.
