Abstract
An air-conditioning system operates in an automatic control mode when an auto-switch is on. When a rotary member which is manually rotated to set one air-conditioning factor is rotated while the auto-switch is on, the air-conditioning system operates in a manual control mode as far as the one air-conditioning factor. The rotary member can be rotated endlessly. When the rotary member is rotated from one angular position to another when the air-conditioning system is operating in the automatic control mode, the one air-conditioning factor is set to a mode or a value which is determined on the basis of the amount of rotation and the mode or the value to which it had been set when the rotary member was in the one angular position.
Claims5
An air-conditioning system for a vehicle comprising
- a control means which controls the air-conditioning system either in an automatic control mode in which the control means automatically sets a plurality of air-conditioning factors such as the speed of a blower motor, the blow mode and the like and controls the air-conditioning system according to the air-conditioning factors automatically set or in a manual control mode in which the air-conditioning factors are manually set and the control means controls the air-conditioning system according to the air-conditioning factors which are manually set,
- an auto-switch which is turned on to cause the control means to control the air-conditioning system in the automatic control mode and is turned off to cause the control means to control the air-conditioning system in the manual control mode,
- a rotary member which can be rotated endlessly and is manually rotated to set one of said air-conditioning factors when the auto-switch is off,
- an angular position detecting means which detects the angular position of the rotary member and stores it,
- a memory means which stores the value or the mode to which said one air-conditioning factor is set,
- a calculating means which calculates the amount of rotation of the rotary member and the direction of rotation of the same when the rotary member is rotated from one angular position to another, and
- an air-conditioning factor setting means which sets said one air-conditioning factor to a mode or a value which is determined on the basis of the amount and the direction of rotation of the rotary member and the mode or the value to which said one air-conditioning factor had been set when the rotary member was in said one angular position.
