This control is capable of effecting complex control by artificially simulating
the information processing method of the nervous system of living organisms
in order to establish a complex input or output relationship that is similar to a
human brain.
In compliance with the temperature set at the temperature control switch, the
neural network control calculates the outlet temperature based on the input
signals from various sensors. In addition, corrections in accordance with the
signals from the evaporative temperature sensor and water temperature sensor
are added to control the outlet air temperature.
Controls the blower motor in accordance with the airflow volume that has
been calculated by the neural network control based on the input signals from
various sensors.
Automatically switches the outlets in accordance with the outlet mode ratio
that has been calculated by the neural network control based on the input
signals from various sensors.
Activated by the micro dust and pollen filter mode switch operation.
Switches the air vent to the FACE mode.
Sends air which has passed through the clean air filter to the area around
the upper part of the bodies of the driver and front passenger. This air is
filtered by the clean air filter in order to remove pollen.
Automatically controls the air inlet control damper in accordance with the
outlet temperature that has been calculated by the neural network control.
The A/C amplifier calculates the target speed of the compressor based on the
target evaporator temperature (which is calculated by the temperature control
switch, room temperature sensor, ambient temperature sensor, and solar
sensor) and the actual evaporator temperature that is detected by the
evaporator temperature sensor in order to control the compressor speed.
The A/C amplifier calculates the target evaporator temperature, which
includes corrections based on the temperature control switch, room
temperature sensor, ambient temperature sensor, solar sensor, and evaporator
temperature sensor. Accordingly, the A/C amplifier controls the compressor
speed to an extent that would not inhibit the proper cooling performance or
defogging performance.
When the hybrid control system is operating (READY), and the blower motor
is turned on, the A/C amplifier turns on the PTC heater assembly if the
conditions listed below are met:
Engine coolant temperature is below specified temperature.
Outside temperature is below specified temperature
Tentative air mix damper opening angle is above the specified value (MAX
