Figure 10.1: A reduced model <strong>of</strong> the MUTE car cabin.<br />
equation 3.3. As this is not possible yet <strong>for</strong> the MUTE car, a st<strong>an</strong>dard value [1] is taken<br />
<strong>an</strong>d scaled <strong>for</strong> the car size as proposed.This value <strong>of</strong> is used as a const<strong>an</strong>t <strong>an</strong>d<br />
ch<strong>an</strong>ges have to be considered by the disturb<strong>an</strong>ce estimator.<br />
The interior parts are mainly made out <strong>of</strong> synthetic material. Only a rough esti-<br />
mation c<strong>an</strong> be made since not all the parts are constructed <strong>an</strong>d the materials (at least<br />
<strong>for</strong> the prototype car) are not defined, yet. For the interior part a mass <strong>of</strong> <strong>an</strong>d <strong>an</strong><br />
average heat capacity <strong>of</strong> are assumed. Only the surface <strong>of</strong> these parts interact<br />
with the air <strong>an</strong>d has a temperature close to the cabin air temperature. There<strong>for</strong>e, the<br />
thermal mass is reduced to a replacement value <strong>of</strong> .<br />
With the dimensions taken from the CAD-model (seen in Figure 10.1) the following<br />
area weighting factors (cf. equation 8.11) were obtained <strong>for</strong> <strong>an</strong> average passenger position:<br />
