Abstract: A control system for an automotive air conditioner has an ambient air temperature sensor; a solar radiation quantity sensor; a passenger room temperature sensor; a cooled air temperature sensor; an air-mix door open degree sensor; and a bypass door open degree sensor.

Abstract: An air conditioner system for a vehicle having an occupant compartment which includes a driver's occupying area and a front passenger's occupying area. The system includes a vent duct adapted to conduct a conditioned air. The vent duct defines a first passages opening to the driver's occupying area and a second passage opening to the front passenger's occupying area. First and second vent valves are disposed within the first and second passages, respectively. First and second actuators are drivingly connected to the first and second vent valves. A first sensor is so constructed and arranged as to detect insolation magnitude within the driver's occupying area and generate a first sensor signal indicative of the detected insolation magnitude within the driver's occupying area.
