TARGET TEMPERATURE OPERATION

Target Temperature Calculation

• The target temperature is calculated using the following formula based on input from the cabin temperature sensor, the ambient temperature sensor (Correction is added according to vehicle speed.) and the solar radiation sensor, in addition to the temperature set by the climate control unit.

Front (driver side)

Front target temperature = (K1 x (driver-side set temperature + K2)) - (K3 x cabin temperature) - (K4 x ambient temperature) - (K5 x (C1 x (solar radiation temperature (LH) + solar radiation temperature (RH)))) + C2+ C3
K1-K5 :Control coefficient
C1-C3 :Correction coefficient

Front (passenger side)

Front target temperature = (K1 x (passenger-side set temperature + K2)) - (K3 x cabin temperature) - (K4 x ambient temperature) - (K5 x ((1 - C1) x (solar radiation temperature (LH) + solar radiation temperature (RH)))) + C2+ C3
K1-K5 :Control coefficient
C1-C3 :Correction coefficient

Rear (Rear control switch off)

Rear target temperature = (K1 x (driver-side set temperature + K2)) - (K3 x cabin temperature) - (K4 x ambient temperature) - (K5 x (1/2 (solar radiation temperature (LH) + solar radiation temperature (RH)))) + C
K1-K5 :Rear control coefficient
C :Correction coefficient

Rear (Rear control switch on)

Rear target temperature = (K1 x (rear set temperature + K2)) - (K3 x cabin temperature) - (K4 x ambient temperature) - (K5 x (1/2 (solar radiation temperature (LH) + solar radiation temperature (RH)))) + C1+ C2
K1-K5 :Rear control coefficient
C1-C2 :Correction coefficient
