System and method for predicting remaining oil life in vehicles
Systems and methods are described for predicting a remaining oil life in an engine of a vehicle. One or more parameters of the engine can be monitored over a period of time. A hot compartment temperature can be determined from the parameter. A condition of the oil can be determined based on the hot compartment temperature, and the condition of the oil can be displayed.
1. A method for predicting a remaining oil life in an engine of a vehicle, comprising:
monitoring at least one parameter of the engine over a period of time, wherein the at least one parameter comprises at least a total idle time;
determining a hot compartment temperature from the parameter;
determining a condition of the oil based on the hot compartment temperature; and
displaying the condition of the oil.
2. The method of claim 1 , further comprising starting the monitoring when new oil is added to the engine.
3. The method of claim 1 , where the determining further comprise factoring in real-time data previously obtained from testing performance characteristics of a same make of engine as in the vehicle.
4. The method of claim 1 , where the at least one parameter for determining hot compartment temperature comprises at least one of an exhaust temperature and exhaust related temperature.
5. The method of claim 1 , further comprising telemetrically conveying a condition of oil to a remote party.
6. The method of claim 5 , further comprising determining when to schedule an oil change based on the telemetrically conveyed condition of oil.
7. The method of claim 1 , further comprising sending the at least one parameters from an engine control module.
8. The method of claim 1 , where the at least one parameter further comprises a duty cycle of the engine.
9. The method of claim 1 , where the determining is further based on a previously determined model.
10. The method of claim 9 , where the previously determined model comprises a field test model and an engine stand model.
11. The method of claim 10 , where the determining further includes an empirically determined oil deterioration factor.
12. A system for determining a remaining oil life in an engine of a vehicle, comprising:
an electronic control module configured to monitor at least two parameters of the engine over a period of time, where the at least two parameters include a total idle time and a hot compartment temperature; and
an oil life determination module configured to determine a condition of the oil based on the total idle time and the hot compartment temperature and display the condition of the oil.
13. The system of claim 12 , where the oil life determination module is configured to determine the condition based on when new oil is added to the engine.
14. The system of claim 13 , further including an oil level sensor, where new added is determined by the oil level sensor.
15. The system of claim 12 , where the oil life determination module is configured to determine the condition based on real-time data previously obtained from testing performance characteristics of a same make of engine as in the vehicle.
16. The system of claim 12 , where the hot compartment temperature comprises is determined from an exhaust temperature.
17. The system of claim 12 , further comprising a telematics device, where the telematics device is configured to telemetrically convey a condition of oil to a fleet manager device.
18. The system of claim 17 , where the fleet manager device is configured to schedule an oil change based on the telemetrically conveyed condition of oil.
19. The system of claim 12 , where the parameter further comprises a duty cycle of the engine.
20. The system of claim 12 , where the oil life determination module is configured to determine the condition based on a previously determined model.
21. The system of claim 12 , where a previously determined model comprises a field test model and an engine stand model.
22. The system of claim 12 , where the oil life determination module is further configured to determine the condition based on an empirically determined oil deterioration factor.
