Abstract

A method for climate control for an interior of a motor vehicle includes acquiring climatically relevant data of the interior and/or surroundings of the vehicle, creating a thermodynamic model of a vehicle climate system, the model including at least one of a first thermal capacity of the interior and a first heat loss of the interior, introducing into the interior a quantity of air having a temperature different from an existing interior temperature, calculating at least one of a second thermal capacity of the interior and a second heat loss of the interior existing after the air quantity is introduced into the interior, and adapting the thermodynamic model to include at least one the second thermal capacity and the second heat loss.

First claim

What is claimed is:

1. A vehicle system comprising:
a controller programmed to, upon setting climate control heating to maximum and a speed of a fan to minimum,
increase the speed,
measure a temperature change in a heat source used for the heating or in air conveyed by the fan,
calculate an updated available heat quantity based on at least the temperature change,
compare the updated available heat quantity with an original value to generate a difference, and
substitute the updated available heat quantity for the original value into a thermodynamic model of the vehicle climate system residing in and implemented by the controller responsive to the difference being greater than a prescribed tolerance range.

2. The system of claim 1 , wherein the controller is further configured to perform the setting responsive to ambient temperature being less than a limit value.

3. The system of claim 1 , wherein the controller is further configured to perform the increase only if engine speed is constant.

4. The system of claim 1 , wherein the controller is further configured to perform the setting on a basis of a time trigger or an event trigger.

5. The system of claim 1 , wherein the controller is further configured to perform the increase only if engine load is constant.

6. The system of claim 1 , wherein the controller is further configured to store a power associated with the fan as a maximum value responsive to the difference being greater than the prescribed tolerance range.
