Patent ID: 6918543

Claim:
Heating system for a vehicle, comprising: a heating air fan ( 24 ) for producing a heating air flow to be introduced into a vehicle interior ( 14 ), a heating device ( 22 ) with a heat exchanger arrangement ( 26 ) for heating the heating air flow delivered by the heating air fan ( 24 ), a vehicle interior temperature sensor arrangement ( 50 ) for producing an output in dependence on the temperature in the vehicle interior ( 14 ), a vehicle interior reference temperature predetermining arrangement ( 56 ), a heating air flow temperature sensor arrangement ( 44 ) for producing a second output connection with the outlet temperature of the heating air flow heated by the heating device ( 22 ), a control device ( 42 , 46 ) which is arranged to set the delivery capacity of the heating fan ( 24 ) in dependence on the first output and on the vehicle interior reference temperature predetermined by the vehicle interior reference temperature arrangement ( 56 ), and to set the heating capacity of the heating device ( 22 ) in dependence on the second output, wherein the delivery capacity of the heating air fan ( 24 ), or a quantity representing the delivery capacity of the heating air fan, does not form an input quantity, on which the control of the heating device ( 22 ) is to be based for the control device ( 42 , 46 ).
