Abstract
A vehicle air conditioning system uses a non-contact temperature sensor for feedback control of the temperature of the air blown out from a blowing opening. The degrees of opening of an air mix damper and a bypass open/close damper are controlled by actuators that respond in accordance with a temperature detected by the non-contact sensor so the blowing temperature will ultimately approach a target value. Air conditioning control is achieved as desired by this feedback control of the blowing temperature without providing wiring for a temperature sensor near the blowing opening.
Claims16
A vehicle air conditioning system having a temperature adjusting means for adjusting a blowing temperature of conditioned air from a blowing opening into a passenger compartment, the system comprising:
- a non-contact temperature sensor for detecting a temperature, in a non-contact manner, of a sensing region including at least one blowing opening;
- and
- means for controlling the temperature adjusting means to achieve a desired temperature adjustment of the blown air using the temperature detected by the non-contact temperature sensor.
A vehicle air conditioning system comprising:
- means for adjusting a temperature of an interior material in a passenger compartment;
- a non-contact temperature sensor for detecting a temperature, in a non-contact manner, of a sensing region including at least the interior material;
- and
- control means for controlling the temperature adjusting means to achieve temperature adjustment of the temperature of the interior material using the temperature detected by the non-contact temperature sensor.
A vehicle air conditioning system for adjusting a temperature of blown air to blow out conditioned air from a blowing opening to a passenger compartment, the system comprising:
- a non-contact temperature sensor for detecting a temperature, in a non-contact manner, of a sensing region thereof including at least one blowing opening;
- and
- selecting means for selecting from which blowing opening to blow out air based on the temperature detected by the non-contact temperature sensor.
A computer-readable recording medium for storing a program for allowing a computer used with a vehicle air conditioning system, having a temperature adjusting means for adjusting a temperature of blown air to blow out conditioned air from a blowing opening into a passenger compartment, to serve as a control means in a manner such that the temperature adjusting means is controlled to achieve a desired temperature adjustment of blown air, using a temperature of a sensing region thereof including at least one blowing opening detected by a non-contact temperature sensor.
A computer-readable recording medium for storing a program for allowing a computer used with a vehicle air conditioning system having a temperature adjusting means for adjusting a temperature of an interior material in a passenger compartment and a non-contact temperature sensor for detecting a temperature of a sensing region thereof including at least the interior material in a non-contact manner, to serve as a control means in a manner such that the temperature adjusting means is controlled to adjust the temperature of the interior material using the temperature detected by the non-contact temperature sensor.
A computer-readable recording medium for storing a program for allowing a computer used with a vehicle air conditioning system for adjusting a temperature of blown air to blowout conditioned air from a blowing opening (31) to a passenger compartment, to serve as selecting means for selecting from which blowing opening to blow out air using the temperature of a sensing region thereof including at least one blowing opening detected by a non-contact temperature sensor.
A vehicle air conditioning system, including a face blowing opening communicating to a first passageway, a foot blowing opening communicating to a second passageway, and at least one of a third blowing opening and an interior material portion whose temperature is adjustable, the third blowing opening and interior material portion being arranged in the vicinity of a passenger and communicated to a third passageway, the system comprising:
- a non-contact temperature sensor mounted inside a passenger compartment and oriented so that a sensing region thereof includes an entirety of one of said third blowing opening and said temperature-adjustable interior material portion;
- means for calculating a required blowing temperature using at least a set temperature;
- means for calculating a target blowing temperature from said required blowing temperature;
- and
- temperature adjusting means for causing the temperature of air inside said third passageway to approach said target blowing temperature in accordance with at least said target blowing temperature and an entire surface temperature of one of said third blowing opening and said temperature-adjustable interior material portion detected by said non-contact temperature sensor.
