- Correction for input value
Ambient temperature correction
- A/C auto amp. inputs the temperature detected by ambient sensor as the ambient temperature.
- A/C auto amp. performs the correction of the temperature detected by ambient sensor for air conditioning control.
- A/C auto amp. selects and uses the initial value of ambient temperature data depending on the engine coolant temperature when turning the ignition switch from OFF to ON. The detection temperature of the ambient sensor is used when engine coolant temperature is low [less than approximately 56 deg. C (133 deg. F)]. The memory data (before the ignition switch is OFF) when the engine is warmed up [approximately 56 deg. C (133 deg. F) or more].
- The correction of the ambient temperature is not performed when the detection temperature of the ambient temperature is less than approximately -20 deg. C (-4 deg. F).
In-vehicle temperature correction
- A/C auto amp. inputs the temperature detected by in-vehicle sensor as the in-vehicle temperature.
- A/C auto amp. performs the correction of the temperature detected by in-vehicle sensor for air conditioning control.
- A/C auto amp. performs the correction so that the recognition passenger room temperature changes depending on the difference between the detected passenger room temperature and the recognition passenger room temperature. If the difference is large, the changing is early. The changing becomes slow as the difference becomes small.
Intake temperature correction
- A/C auto amp. inputs the temperature detected by intake sensor as the intake temperature (evaporator temperature).
- A/C auto amp. performs the correction of the temperature detected by intake sensor for air conditioning control.
- A/C auto amp. performs the correction so that the recognition intake temperature changes depending on the difference between the detected intake temperature and the recognition intake temperature. If the difference is large, the changing is early. The changing becomes slow as the difference becomes small.
Sunload amount correction
- A/C auto amp. inputs the sunload amount detected by sunload sensor.
- A/C auto amp. performs the correction of the sunload amount detected by sunload sensor for air conditioning control.
- When the sunload amount suddenly changes, for example when entering a tunnel, perform the correction so that the recognition sunload amount of the A/C auto amp. changes slowly.
Set temperature correction
- A/C auto amp. performs the correction to the target temperature set by the temperature control switch so as to match the temperature felt by the passengers depending on the ambient temperature detected by ambient sensor and controls it so that the in-vehicle temperature is always the most suitable.
