PURPOSE:To aim at optimizing the control of air-condition without being restrained by the characteristic of a solar radiation sensor, by compensating the output characteristic of the solar radiation sensor which is specified only by the incidence angle of sunlight in relation to the actual quantity of solar radiation to the driver. CONSTITUTION:A solar radiation sensor 1 is disposed in the vicinity of the driver's seat in an automobile with the sensing surface of the sensor 1 being laid in the substantially horizontal direction, and a vehicle air-conditioning device 2 is controlled in accordance with the output of the sensor 1. In the above-mentioned arrangement, an output compensating circuit 3 increases the output level of the solar radiation sensor 1 in accordance with a predetermined coefficient value. Further, an output limit means 5 compares the compensating value from the circuit 3 with a predetermined set value from a set value memory means 4, and if the compensating value exceeds the set value, the air-conditioning device 2 is controlled in accordance with the set value by means of a switch means 6. With this arrangement, the output characteristic of the solar radiation sensor 1 which is specified only by the incidence angle of the sunlight is compensated in relation to the actual quantity of solar radiation to the driver. |
