Abstract
A control unit for an air conditioning system of a vehicle is provided, wherein the air conditioning system has automatic climate control. The control unit is configured to calculate a fan strength limitation specified by a user. The control unit is further configured to activate the fan of the air conditioning system for automatic climate control depending on a fan characteristic curve and depending on the fan strength limitation, wherein the fan characteristic curve displays a fan strength for a fan of the air conditioning system as a function of a control deviation of the automatic climate control.
Claims10
A vehicle air conditioning system having an automatic climate control, comprising:
- a user interface configured to simultaneously display all possible fan strengths of a fan of the air conditioning system on a screen of the user interface, and through which a maximum allowable fan strength during automatic operation of the fan and a minimum allowable fan strength during the automatic operation of the fan are adjustable by a user as a fan strength limitation for the fan of the air conditioning system from all of the possible fan strengths of the fan;
- and
- a processor of the air conditioning system having the automatic climate control, wherein the processor is programmed to execute a process to:
- determine the fan strength limitation specified by the user of the system;
- and
- activate the fan of the air conditioning system for the automatic climate control depending on a fan characteristic curve and depending on the fan strength limitation, such that a range of usable fan strengths during the automatic operation of the fan is limited by the fan strength limitation instead of all possible fan strengths,
- wherein a fan strength for the fan of the air conditioning system is controlled as a function of a control deviation value of the automatic climate control, the control deviation value indicating a degree to which a climate parameter differs from a target value, to adjust the climate parameter to the target value.
A method of controlling a fan of a vehicle air conditioning system having automatic climate control, the method comprising the acts of:
- simultaneously displaying all possible fan strengths of a fan of the air conditioning system on a screen of a user interface;
- determining a fan strength limitation, including a maximum allowable fan strength during automatic operation of the fan and a minimum allowable fan strength during the automatic operation of the fan, input by a user of the air conditioning system via the user interface through which the user adjusts the fan strength limitation for the fan of the air conditioning system from all of the possible fan strengths of the fan;
- and
- controlling the fan for the automatic climate control depending on a fan characteristic curve and depending on the fan strength limitation, such that a range of usable fan strengths during the automatic operation of the fan is limited by the fan strength limitation instead of all possible fan strengths;
- wherein a fan strength for the fan is controlled as a function of a control deviation value of the automatic climate control, the control deviation value indicating a degree to which a climate parameter differs from a target value, to adjust the climate parameter to the target value.
