In a vehicle air conditioner for a vehicle cabin interior is split into a plurality of air-conditioned zones, that is capable of independent air conditioning control for individual air-conditioned zones, provided is a solar radiation sensor that measures solar radiation levels individually for a first air-conditioned zone and a second air-conditioned zone adjacent thereto; a judging unit (100) that judges whether or not a difference between the solar radiation level of the first air-conditioned zone and the solar radiation level of the second air-conditioned zone falls within a predetermined range; a first controller (101) that performs identical air conditioning control for the first air-conditioned zone and the second air-conditioned zone when the difference falls within the predetermined range; and a second controller (102) that performs independent air conditioning control individually for the first air-conditioned zone and the second air-conditioned zone when the difference falls outside the predetermined range.

1. A vehicle air conditioner for a vehicle cabin interior split into a plurality of air-conditioned zones that is capable of independent air conditioning control for individual air-conditioned zones, comprising: a solar radiation sensor that measures solar radiation levels individually for a first air-conditioned zone and a second air-conditioned zone, which are adjacent to each other;a judging unit that judges whether or not a difference between the solar radiation level of the first air-conditioned zone and the solar radiation level of the second air-conditioned zone falls within a predetermined range;a first controller that performs identical air conditioning control for the first air-conditioned zone and the second air-conditioned zone when the difference falls within the predetermined range; anda second controller that performs independent air conditioning control individually for the first air-conditioned zone and the second air-conditioned zone when the difference falls outside the predetermined range,wherein, of the first air-conditioned zone and the second air-conditioned zone, the first controller selects the air-conditioned zone with a higher solar radiation level as a first reference zone and performs the air conditioning control of the first air-conditioned zone and the second air-conditioned zone on the basis of the solar radiation level of the first reference zone, andwherein, of the first air-conditioned zone and the second air-conditioned zone, the second controller selects one zone as a second reference zone, corrects a control value for the second reference zone on the basis of a difference between a solar radiation level of the second reference zone and a solar radiation level of the other air-conditioned zone, and computes and adjusts a control value for the other air-conditioned zone. 2. A vehicle air conditioner according to claim 1, wherein the second controller selects the air-conditioned zone with a higher solar radiation level as the second reference zone. 3. A vehicle air conditioner according to claim 1, wherein, of the first air-conditioned zone and the second air-conditioned zone, the second controller selects one zone as a second reference zone and performs the air conditioning control for the other air-conditioned zone on the basis of the solar radiation level of the second reference zone. 4. A vehicle air conditioner according to claim 3, wherein the second controller selects the air-conditioned zone with a higher solar radiation level as the second reference zone. 5. A control method for a vehicle air conditioner for a vehicle cabin interior split into a plurality of air-conditioned zones, that is capable of independent air conditioning control for individual air-conditioned zones, using a controller comprising: a step of measuring solar radiation levels individually for a first air-conditioned zone and a second air-conditioned zone, which are adjacent to each other, and judging whether or not a difference between the solar radiation level of the first air-conditioned zone and the solar radiation level of the second air-conditioned zone falls within a predetermined range;a first controlling step of performing identical air conditioning control for the first air-conditioned zone and the second air-conditioned zone when the difference falls within the predetermined range; anda second controlling step of performing independent air conditioning control individually for the first air-conditioned zone and the second air-conditioned zone when the difference falls outside the predetermined range,wherein, of the first air-conditioned zone and the second air-conditioned zone, the air-conditioned zone with a higher solar radiation level is selected by the first controlling step as a first reference zone, and the air conditioning control of the first air-conditioned zone and the second air-conditioned zone is performed on the basis of the solar radiation level of the first reference zone, andwherein, of the first air-conditioned zone and the second air-conditioned zone, one zone is selected as a second reference zone, a control value for the second reference zone on the basis of a difference between a solar radiation level of the second reference zone and a solar radiation level of the other air-conditioned zone is corrected, and a control value for the other air-conditioned zone is computed and adjusted by the second controlling step. 6. A vehicle air conditioner program that is a control program applied to a vehicle air conditioner for a vehicle cabin interior split into a plurality of air-conditioned zones, which is capable of independent air conditioning control for individual air-conditioned zones, and that causes a computer to execute: judgment processing in which solar radiation levels are individually measured for a first air-conditioned zone and a second air-conditioned zone, which are adjacent to each other, and it is judged whether or not a difference between the solar radiation level of the first air-conditioned zone and the solar radiation level of the second air-conditioned zone falls within a predetermined range;first control processing of performing identical air conditioning control for the first air-conditioned zone and the second air-conditioned zone when the difference falls within the predetermined range; andsecond control processing of performing independent air conditioning control individually for the first air-conditioned zone and the second air-conditioned zone when the difference falls outside the predetermined range,wherein, of the first air-conditioned zone and the second air-conditioned zone, the air-conditioned zone with a higher solar radiation level is selected by the first control processing as a first reference zone, and the air conditioning control of the first air-conditioned zone and the second air-conditioned zone is performed on the basis of the solar radiation level of the first reference zone, andwherein, of the first air-conditioned zone and the second air-conditioned zone, one zone is selected as a second reference zone, a control value for the second reference zone on the basis of a difference between a solar radiation level of the second reference zone and a solar radiation level of the other air-conditioned zone is corrected, and a control value for the other air-conditioned zone is computed and adjusted by the second control processing.
