A system for controlling temperature of air to be discharged into a cabin of a vehicle in an automatically controlled air conditioner system of an automotive vehicle. The air conditioner system is provided with a cooling unit and a heating unit for cooling and heating conditioning air in the air conditioner system for delivery to the cabin of the vehicle. The air conditioner system includes a mechanism for mixing the cooling air and the heating air in a stepwise manner so as to generate a controlled temperature of conditioning air to be discharged into the vehicle cabin with a moderate adjustment in transition so as to maintain a desired vehicle cabin temperature.

An automotive air conditioning system for controlling the air temperature of a vehicle cabin comprising: (a) passage means for conditioning air, said passage means having inlet means for receiving air to be conditioned in said passage means and outlet means for delivering conditioned air to said vehicle cabin; (b) cooling means provided in said passage means between said inlet means and said outlet means for selectively cooling said air received from said inlet means; (c) heating means provided in said passage means downstream of said cooling means for selectively heating said air received from said inlet means, said heating means having an inlet to introduce said air to be heated thereto and an outlet to discharge heated air therefrom; (d) flow control means for selectively controlling the amount of air introduced to said heating means through said inlet; (e) temperature control means for selecting a desired vehicle cabin temperature (Ts); (f) first means for continually monitoring ambient temperature (Ta), insolation (Z), vehicle cabin temperature (Tr), discharge air temperature to cabin vehicle (Td) and desired vehicle cabin temperature (Ts) so as to derive a target discharge air temperature (Tdo) for the conditioned air delivered to said vehicle cabin so as to obtain the desired cabin temperature (Ts); and (g) second means for continually comparing said discharge air temperature (Td) with said target discharge air temperature (Tdo) and operating said flow control means in response to the difference (DD
