Problems solved by technology

However, when the occupant is only the driver, the heating capacity is reduced compared to the case where all seats are occupied by occupants
If the frequency of starting the engine in this situation is increased to raise the water temperature to the set water temperature, the energy efficiency becomes poor

Embodiment Construction

[0051] Examples will refer to Figure 1-15 be described. The air conditioner 100 according to the embodiment is installed in a hybrid car. A hybrid vehicle is configured to include an engine 60 for traveling, an engine starting device (not shown), an electric motor 61 for traveling, a hybrid ECU (Electronic Control Unit) (not shown), and an engine ECU 63 .

[0052] The engine 60 is connected in a connectable and detachable state so as to drive an axle of the hybrid vehicle. The electric motor 61 is connected in a connectable and detachable state so as to drive a shaft of the hybrid vehicle. When the engine 60 is not connected to the shaft, the electric motor 61 is connected to the shaft. Therefore, one of the engine 60 and the electric motor 61 is connected to the shaft, and the other is not connected to the shaft. The electric motor 61 is configured to be automatically controlled (eg, inverter controlled) by the hybrid ECU. The engine starting device starts the engine 60...

Abstract

When a control section (10) determines that the cooling water temperature detected by a water-temperature detecting section (75) is lower than a threshold, the control section outputs a signal that requests engine startup. In a normal state in which air-conditioning wind is blowing out toward a specific seat and other seats, the control section adjusts the threshold so as to lower the threshold in accordance with the amount of increase in the heat generation amount of an auxiliary heating device (65) on the basis of the operational state of the auxiliary heating device. If the control section receives a specific-seat air-conditioning command to air-condition the specific seat, then, as a control for the specific-seat state, the control section performs a control so as to shut off outlet opening / closing sections (34-36), and adjusts the threshold so as to lower the threshold even further than the threshold adjusted in the normal state.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2011-93281 filed on April 19, 2011, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to an air conditioner for a vehicle. Background technique [0004] Generally, in an air conditioner of a hybrid vehicle, it is necessary to determine whether a cabin needs to be heated based on sensor signals output by an inside air temperature sensor and an outside air temperature sensor. When it is determined that it is necessary to heat the cabin and when the temperature of the cooling water of the engine is low, the engine will be activated even if the engine is suspended because the hybrid vehicle has just started driving or is driving at a low speed. Therefore, the cooling water sufficiently heated in the cooling water jacket of the engine can be supplied to the heater core so that the heat source is se...
