AIR CONDITIONING SYSTEM (for Automatic Air Conditioning System) SYSTEM DESCRIPTION


  1. GENERAL


    1. The air conditioning system has the following features:


      • An automatic, dual-control air conditioner system comprising front/rear independent temperature control is used.

      • In accordance with the temperature set using the temperature control switch, the air conditioning amplifier determines the outlet temperature based on the input signals from various sensors. In addition, corrections are made in accordance with the signals from the water temperature sensor to control the outlet air temperature.

      • Controls the blower motor in accordance with the airflow volume determined by the air conditioning amplifier based on the input signals from various sensors.

      • Automatically changes the outlets in accordance with the outlet mode ratio that is determined by the air conditioning amplifier based on the input signals from various sensors.

      • Based on the signals from the ambient temperature sensor, this system calculates the outside temperature and indicates it in the multi-information display.

      • The left/right independent temperature control and neural network control make air conditioner control available to suit the persons in the driver seat and in the passenger seat.

      • The Positive Temperature Coefficient (PTC) heater system contains a PTC heater that heats the air that has passed through the heater core to ensure the proper heater performance.

      • Turns the rear defogger and outside rear mirror heaters on for 15 minutes when the rear defogger switch is pressed. Turns them off if the switch is pressed while they are operating.

      • Checks the sensors in accordance with the operation of the air conditioner switches.

      • The air conditioning amplifier has the function of controlling the indicator lighting.

      • When a high load is applied to the EPS system, the EPS ECU will send a signal to the air conditioning amplifier. After receiving the signal, the air conditioning amplifier may turn off the rear defogger, front deicer, and seat heaters.
