Vehicle air-conditioning control apparatus
First Claim
1. A vehicle air-conditioning control apparatus comprising:
- a sunlit illumination sensor including a plurality of photodetectors which have sensitivity characteristics varying with an incident angle of light and which are arranged such that their light receiving surfaces are oriented differently;
a sunlit illumination correction controlling unit responsive to output signals of said plurality of photodetectors to produce sunlit illumination correction controlling signals; and
an air conditioning unit for controlling temperatures in a room of a vehicle in accordance with the sunlit illumination correction controlling signals,said sunlit illumination correction controlling unit including incident angle calculation means which calculates, on the basis of the output signals of said plurality of photodetectors, an angle the sunlight ray makes to either of the righthand side and lefthand side of the vehicle and an angle of elevation of the sun relative to a horizontal plane of said vehicle and produces calculation results as the sunlit illumination correction controlling signals,said air conditioning unit including flow rate distribution control means, responsive to the calculated angle and the angle of elevation, for controlling air supply amounts to be distributed to the righthand and lefthand sides on a horizontal plane within the vehicle room.

Abstract
In a vehicle air-conditioning control apparatus for controlling the temperature and amount of air to be supplied to the interior of a vehicle room to control the air temperature in the room to a command value, a sunlit illumination sensor is provided including a plurality of photodetectors which have sensitivity characteristics varying with an incident angle of light and which are so arranged as to be oriented in different directions, an incident angle calculator is provided which calculates, on the basis of output signals of the photodetectors, an angle the sunlight ray makes to either of the righthand side and lefthand side of the vehicle and an angle of elevation of the sun relative to the horizontal plane of the vehicle, and distribution of air supply amounts on a horizontal plane within the room is controlled in accordance with calculated values delivered out of the incident angle calculator.
