Title: AIR CONDITIONING: AIR CONDITIONING SYSTEM (for Automatic Air Conditioning System): SYSTEM
DESCRIPTION; 2016 MY Tacoma [08/2015 - ]
SYSTEM DESCRIPTION
1. GENERAL
(a) The air conditioning system has the following controls.
CONTROL OUTLINE
Neural Network
Control
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/output relationship that is similar to a human brain.
Outlet Air
Temperature
Control
Based on the temperature set at the temperature control switch, the neural network control
calculates the outlet air temperature based on the input signals from various sensors.
Left and Right
Independent
Control
The temperature setting for the driver and front passenger is controlled independently in
order to provide a separate vehicle interior temperature for the right and left side of the
vehicle. Thus, air conditioning control that accommodates occupant preferences has been
realized.
Blower Control
Controls the blower motor in accordance with the airflow volume that has been calculated by
neural network control based on the input signals from various sensors.
Air Outlet Control
Automatically switches the air outlets in accordance with the outlet mode that has been
calculated by neural network control based on the input signals from various sensors.
In accordance with the engine coolant temperature, ambient air temperature, amount of
sunlight, required blower, outlet temperature, and vehicle speed conditions, this control
automatically switches the blower outlet to foot and defroster mode to prevent the windows
from becoming fogged up when the ambient air temperature is low.
Air Inlet Control
Automatically controls the air inlet control damper to achieve the calculated outlet air
temperature that is required.
Drives the air inlet servo motor (damper servo sub-assembly) according to the operation of
the air inlet control switch and moves the dampers to the fresh or recirculation position.
Automatically moves the damper to the recirculation position to cool the cabin quickly when
the air conditioning is auto mode.
Compressor
Control
Controls the compressor with magnet clutch assembly to turn on or off based on the signals
from various sensors.
Diagnosis
A Diagnostic Trouble Code (DTC) is stored in the memory when the air conditioner amplifier
assembly detects a problem with the air conditioning system.
