Calculation device for calculating substitution temperature of cooling water for driving thermal engine of car, has calibration unit for calculating barycenter between measured and oil temperatures to obtain substitution temperature

摘要

The device (50) has a determination unit (51) for determining a weight coefficient (Cp) from a mapping that associates the weight coefficient with data representative of activation conditions of an additional heater. A calibration unit (55) calculates a barycenter between a measured temperature (TEmes) of a cooling liquid and an oil temperature (TH) by applying the weight coefficient to obtain a substitution temperature (TEs) of the cooling liquid between the measured temperature of the cooling liquid and the oil temperature. The determination unit is connected to a memorizing unit. Independent claims are also included for the following: (1) a motorized system (2) a method for calculating a substitution temperature of a cooling liquid for driving a thermal engine (3) a computer program comprising a set of instructions for executing a method for calculating a substitution temperature of a cooling liquid for driving a thermal engine.
