Vehicle air conditioner
First Claim
1. An air conditioner for a vehicle comprising:
- an air conditioning unit for conditioning air in a passenger compartment of the vehicle;
a non-contact temperature sensor for detecting a surface temperature of a temperature detection area in the passenger compartment in non-contact;
first calculating means for calculating a first air-conditioning control value, which indicates a first target air conditioning state in the passenger compartment, based on the detected surface temperature of the non-contact temperature sensor;
determining means for determining whether an obstacle exists between the temperature detection area and the non-contact temperature sensor;
second calculating means for calculating a second air-conditioning control value indicating a second target air conditioning state in the passenger compartment based on a current inside air temperature of the passenger compartment when the determining means determines that the obstacle exists between the temperature detection area and the non-contact temperature sensor; and
a control unit for controlling the air conditioning unit, wherein;
when the determining means determines that the obstacle does not exist between the temperature detection area and the non-contact temperature sensor, the control unit controls the air conditioning unit based on the first air-conditioning control value; and
when the determining means determines that the obstacle exists between the temperature detection area and the non-contact temperature sensor, the control unit controls the air conditioning unit based on the second air conditioning control value.

Abstract
In a vehicle air conditioner, a first air-conditioning control value is calculated based on a surface temperature detected by a non-contact temperature sensor in a temperature detection area of a passenger compartment. When it is determined that an obstacle exists between the temperature detection area and the non-contact temperature sensor, a second air-conditioning control value is calculated according to a temperature information that is influenced less by the obstacle than the detected surface temperature. When it is determined that the obstacle does not exist, an air conditioning state of the passenger compartment is controlled based on the first air-conditioning control value. When it is determined that the obstacle exists, the first air-conditioning control value is corrected to approach the second air-conditioning control value to calculate a corrected air-conditioning control value, so that the air conditioning state can be controlled satisfactorily.
