- the set value is stored in the memory.
- the PTC heater 43 enters the MAXHOT condition and expects the maximum heating capacity. Is the upper limit of W number (for example, 600 W). However, if the water temperature rises even at the same outside air temperature, the heat load of heating will decrease, so the W number of the PTC heater 43 will also be reduced proportionally (450 W-> 300 W-> 0 W) to balance the feeling of heating and practical fuel consumption. Further, if the outside air temperature rises as well as the cooling water temperature (for example, not less than ⁇ 9 ° C. and less than 7 ° C.), the heat load is reduced, so the upper limit is relaxed (450 W).
- the cooling water temperature for example, not less than ⁇ 9 ° C. and less than 7 ° C.
- the air conditioner ECU 10 determines whether or not there is cooperation between the seat heater 65 and the presence / absence of the passenger, using the presence / absence of the seat heater 65, the heater ON / OFF state with the seat, and the passenger's boarding state as input conditions.

- FIG. 15 is a PTC heater setting table used in step S62.
- FIG. 13 is a flowchart showing an example of a water temperature control process in the temperature control program. The process shown in FIG. 13 is started when the process proceeds to step S25 in FIG.
- step S71 the coolant temperature is acquired by multiplex communication from the EFIECU (engine ECU 63), and the process proceeds to step S72.
- step S72 the lower limit value of the set intermittent permission water temperature is compared with the acquired cooling water temperature. If the cooling water temperature is lower than the lower limit value, the process proceeds to step S73, and if not, the process proceeds to step S74. Move.
- step S73 since the cooling water temperature is low, it is necessary to heat the cooling water. Therefore, an engine ON signal requesting to start the traveling engine 60 is output to the engine ECU 63, and the process returns to step S71.

If the cooling water temperature is higher than the upper limit value, the process proceeds to step S75, and if not, the process proceeds to step S71. Return. When it is not high, the cooling water temperature is between the upper limit value and the lower limit value.
- step S75 since the cooling water temperature is high and it is not necessary to heat the cooling water, an engine OFF signal requesting that the traveling engine 60 be stopped is output to the engine ECU 63, and the process returns to step S71.
- the cooling water temperature can be controlled to be between the lower limit value and the lower limit value of the intermittent permission water temperature.
- the air conditioner ECU 10 according to the amount of increase in the amount of heat generated by the seat heater 65 based on the operating state of the seat heater 65 in the normal state (no coordination) in which the conditioned air is blown to the specific seat and other seats. It adjusts so that a threshold value (intermittent permission water temperature) may be lowered
- the intermittent permission water temperature is lowered stepwise according to the amount of increase in the heat generation amount. Accordingly, as the amount of heat generated by the seat heater 65 increases, it becomes more difficult to determine that the temperature of the cooling water of the traveling engine 60 is lower than the threshold value, so that it becomes difficult to output a request signal that requests the starting of the traveling engine 60. . As a result, in the normal state, the amount of heat generated by the seat heater 65 is taken into consideration, so that it is difficult to start the traveling engine 60. Therefore, deterioration in fuel consumption can be suppressed while ensuring heating performance.
- a threshold value intermittent permission water temperature
- the air conditioner ECU 10 controls each door to a closed state as control of the specific seat state when a specific seat air conditioning command for air conditioning the specific seat is given. By setting the shut-off state, the conditioned air can be blown only to the specific occupant seated in the specific seat. Therefore, since the air conditioning range is narrower than in the normal state, the air conditioning capability can be reduced. Further, the air conditioner ECU 10 adjusts the threshold value to be further lower than the threshold value adjusted in the normal state in the specific seat state (see FIG. 14). Therefore, in the specific seat state, as the amount of heat generated by the seat heater 65 increases, it becomes more difficult to determine the temperature of the cooling water of the traveling engine 60 below the threshold value. It becomes difficult to output a request signal for requesting.
- the air conditioning range is narrowed and the amount of heat generated by the seat heater 65 is taken into consideration, so that it is further difficult to start the traveling engine 60. Therefore, deterioration in fuel consumption can be suppressed while ensuring heating performance.
- control panel 90 is further included as an input unit for inputting the specific seat air conditioning command, so that the occupant operates the centralized control switch 55 of the control panel 90 to control the specific seat state from the normal state control. It is possible to shift to control. Therefore, the control in the specific seat state can be performed at any timing of the occupant without using a sensor for detecting the occupant. Thus, it is possible to realize the vehicle air conditioner 100 that can shift to the control of the specific seat state with a simple configuration that does not use a sensor that detects an occupant.
- the passenger detection unit is the passenger seat seating sensor 77 and the passenger seat buckle sensor 78. Therefore, the presence or absence of a passenger in the passenger seat is detected by the two detection units.
- the air conditioner ECU 10 determines that there is an occupant in the passenger seat in at least one of the case where the seatbelt is detected by the passenger seat buckle sensor 78 and the case where the passenger seating sensor 77 detects the seating. to decide. Accordingly, even when the seat belt is not detected in the passenger seat, if the seat is detected by the passenger seat seating sensor 77, it is determined that there is an occupant in the seat. Thus, for example, even when the seat belt is not worn while the vehicle is stopped, the presence or absence of the passenger can be detected by the passenger seat seating sensor 77, and the detection accuracy can be improved.
- the operation and effect of this embodiment are: a passenger seat seating sensor 77 and a passenger who are connected in parallel to the riding state portions of the driver seat (Fr-Dr seat), the passenger seat (Fr-Pa seat) and the rear seat (Rr seat).
- An occupant is detected by the seat buckle sensor 78 and the central control switch 55.
- the intermittent permission water temperature which has been lowered uniformly, is lowered stepwise, making it more comfortable with air conditioning than before. Both feeling and fuel saving can be achieved. Therefore, the present embodiment is based on the idea that comfort and fuel saving are possible even if the water temperature of the heater core 42 is lowered if the seat heater 65 is turned on.
- the passenger seat buckle sensor 78 and the passenger seat seating sensor 77 are connected in series, seating detection cannot be performed in a seated state in which the passenger seat buckle is removed during a break (stopped).
- the passenger seat buckle sensor 78 and the passenger seat seating sensor 77 are arranged in parallel, so that this control can be executed even in a seated state where there is no buckle during a break, for example. Therefore, this control works and the frequency of fuel saving control can be increased even in a sitting state where a buckle is not taken during a break.
- the intermittent permission water temperature is lowered stepwise according to the amount of increase in heat generation, but is not limited stepwise, and the threshold is set to gradually decrease as the amount of heat generation increases. Also good.
- the auxiliary heating device is the PTC heater 43 and the seat heater 65, but is not limited to the PTC heater 43 and the seat heater 65, and may be a steering heater. Moreover, it is not restricted to the PTC heater 43, A water overheat heater and a combustion type heater may be sufficient.
- the vehicle air conditioner 100 capable of independently air-conditioning the driver seat side space and the passenger seat side space in the vehicle interior is not limited to such a configuration, and the vehicle is not air conditioned independently. It may be an air conditioner for industrial use.
