| 发明名称 | Temperature sensor rationalization | ||
| 摘要 | A method of rationalizing a plurality of temperature sensors associated with a plurality of electrical systems of a vehicle includes: maintaining each of the respective electrical systems of the vehicle in a non-operational state for a predetermined period of time; receiving a temperature reading from each of the plurality of temperature sensors following the predetermined period of time; computing a master-reference temperature value from the plurality of received temperature readings; determining a difference between each of the respectively received temperature readings and the computed master-reference temperature value; comparing each determined difference to a threshold; and providing an indicator if one or more of the determined differences exceeds the threshold. | ||

| 主权项 | 1. A method of rationalizing a plurality of temperature sensors, each of the plurality of temperature sensors being coupled with a respective electrical system of a vehicle, the method comprising: receiving an indication of an operator-initiated vehicle power down event, wherein the power down event places each of the respective electrical systems of the vehicle in a non-operational state; maintaining each of the respective electrical systems of the vehicle in the non-operational state for a predetermined period of time such that each of the electrical systems cool from a respective operating temperature to a common ambient temperature; receiving an indication of an operator-initiated power-on event following the predetermined period of time; receiving a temperature reading from each of the plurality of temperature sensors following the operator-initiated power-on event; computing a master-reference temperature value from the plurality of received temperature readings; determining a difference between each of the respectively received temperature readings and the computed master-reference temperature value; comparing each determined difference to a threshold; and providing an indicator if one or more of the determined differences exceeds the threshold. | ||
