Vehicle air conditioner with front and rear air-conditioning units

An air conditioner for a vehicle having a passenger compartment, the air conditioner comprising:

• a front air-conditioning unit including
• a front air-conditioning case for defining a front air passage through which air flows, the front air-conditioning case having an air introduction port for introducing air outside the passenger compartment and air inside the passenger compartment, and an air outlet from which air is blown toward a front seat area of the passenger compartment,
• a front blower for blowing air introduced from the air introduction port,
• a front heater for heating air blown from the front blower,
• a front adjustment unit for adjusting an air heating amount by the front heater,
• a detecting unit for detecting an environment condition including an inside temperature of the passenger compartment and an outside temperature of air outside the passenger compartment,
• a temperature setting unit for setting a set temperature in the passenger compartment, and
• a control unit for determining a target air temperature to be blown toward the front seat area based on the set temperature and the environment condition detected by the detecting unit, and for determining at least one of an air blowing capacity of the front blower and an adjustment amount of the front adjustment unit based on the target air temperature;
• and
• a rear air-conditioning unit including
• a rear blower for introducing and blowing air inside the passenger compartment,
• a rear heater for heating air blown by the rear blower,
• a rear setting unit for manually setting one of a blowing capacity of the rear blower and a heating capacity of the rear heater, wherein
• the control unit corrects the target air temperature by a correction value so that the target air temperature becomes lower as one of the blowing capacity and the heating capacity set by the rear setting unit increases, and determines at least one of the blowing capacity of the front blower and the adjustment amount of the front adjustment unit based on the corrected target air temperature;
• and
• the control unit changes the correction value of the target air temperature based on the outside temperature detected by the detecting unit.
