Abstract

The method involves calculating a predicted temperature of a coolant by a primary algorithm (A1), based on functioning parameters of an engine. An error between measured and predicted temperatures of the coolant is calculated. A predicted oil temperature is calculated by a secondary algorithm (A2), based on functioning parameters of the engine. The predicted oil temperature is corrected based on the calculated error. An independent claim is also included for a system to estimate oil temperature of an internal combustion engine.
