  • Publication number: 20150114016
    Abstract: When an air conditioning ECU determines that it is immediately before idling stop, the air conditioning ECU implements a front seat air conditioning mode even if the air conditioning ECU determines that an occupant intensive air-conditioning mode can be implemented. Accordingly, the air conditioning ECU controls opening and closing mechanisms so as to blow a conditioned air from driver's seat side outlet ports, and also blow the conditioned air from a passenger's seat side foot outlet port. Hence, in cooling operation, since a temperature increase of air drawn into an inside air inlet port is limited when the idling stop is carried out, temperature increase of air blown into the vehicle interior from the outlet port can be restricted. In other words, a temperature change in the vehicle interior can be limited when a travel engine stops due to the idling stop.

  • Publication number: 20140157802
    Abstract: A method for controlling blower speed of an air conditioning system in a vehicle having a start/stop engine. A stop event is entered and an ambient temperature and a second temperature (e.g., evaporator) of the air conditioning system are measured. A first cutback limit is determined in response to the ambient temperature. The blower speed is ramped to the first cutback limit The engine is restarted and the blower speed is restored in response to the second temperature reaching a restart threshold. Consequently, a rise in evaporator temperature is delayed so that any to request by the HVAC system to terminate the stop event is also delayed.

  • Patent number: 8745997
    Abstract: An air conditioning system for a start-stop vehicle employs a compressor with a variable displacement. A controller determines a normal Climate Thermal Load (CTL) value for controlling a variable stroke of the variable displacement compressor. A stop event is detected in response to a speed of the vehicle and the occurrence of a predetermined deceleration. During the stop event, the variable stroke is increased by an amount determined in response to the normal CTL value, the speed of the vehicle, and a measure of the deceleration of the vehicle so that an evaporator temperature within the air conditioning system is allowed to decrease while the vehicle is stopping so that climate comfort can be maintained even while the engine is shut off during the subsequent time that the vehicle is stopped.

  • Patent number: 8701427
    Abstract: A method for controlling a vehicle HVAC system to automatically defog a windshield glass and to prevent fogging or condensation of the windshield glass. In-cabin air temperature and relative humidity are measured and used to determine a dewpoint. Further, ambient or outside temperature is measured. If windshield wipers are being used or if the cabin air temperature is less than a predetermined temperature, the ambient air temperature value is used as a glass temperature, otherwise the glass temperature is determined from the ambient air temperature and vehicle speed. A fog margin, which is a measure of the likelihood of fog formation, is based upon the difference between dewpoint and the windshield glass temperature. The fog margin is used to control the HVAC system to anticipate and respond to potential fogging conditions.
