| Abstract: | A method to estimate the external environment temperature is presented here based on multiple linear regression method including intake air temperature, coolant temperature, fuel injection volume and vehicle speed. This method can be used for the situations that do not need high temperature precision （such as less than±2.5℃）. |

| Keywords: | external environment temperature estimation intake air temperature coolant temperature fuel injection volume vehicle speed |
