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. The control system further has a first device which, based on information from the ambient air temperature sensor and the solar radiation quantity sensor, derives a first target temperature of air drawn out from an air outlet structure; a second device which, based on the information from the cooled air temperature sensor and the air-mix door open degree sensor, derives a second target temperature of air drawn out from a foot area air duct; and a third device which, based on the information from the cooled air temperature sensor, the first target temperature and the second target temperature, derives a ratio between the amount of air flowing in a bypass passage and that of air blown out from the air outlet structure; and a fourth device which controls the open degree of the bypass door in accordance with the derived ratio.
