AIR MIX DOOR MOTOR
AIR MIX DOOR MOTOR
System DescriptionINFOID:0000000001547407
SYSTEM DESCRIPTION
Component Parts
Air mix door control system components are: Front air control
Air mix door motor
In-vehicle sensor
Intake sensor
Ambient sensor
Sunload sensor
System Operation
The front air control receives data from each of the sensors. When setting a target temperature by using tem-
perature button, front air control corrects preset temperature, performs an arithmetical operation based on sig-
nals from sensors and determines opening angle of target air mix door.
Air mix door is constantly controlled so as to keep optimum opening angle of air mix door based on target and
present opening angles of air mix door. Air mix door is fixed in the full cold position when preset temperature is
set to 18°C, and full hot position when set to 32°C.
Drive System of Step Motor Type Door Motor
Motor is actuated in sequence by energizing four drive coils.
Rotation direction can be changed by changing pattern of excitation.
