20150097041 | VEHICLE COMPRISING AIR CONDITIONING APPARATUS - A vehicle includes an air conditioning apparatus for heating inside of a passenger compartment using electric power of an external power supply or of the vehicle, the apparatus being configured to be capable of executing a foot mode to blow air toward feet and a moisture prevention mode to blow air also through a defroster unit while the foot mode is selected, and a control unit that causes the air conditioning apparatus to execute remote air conditioning in which air conditioning is performed while a user is not in the vehicle, and operated air conditioning in which air conditioning is performed by the user's operation while the user is in the vehicle. The control unit limits the execution of the moisture prevention mode in the remote air conditioning more than the execution of the moisture prevention mode in the operated air conditioning. | 04-09-2015 |
20150298522 | VEHICLE AND METHOD FOR CONTROLLING VEHICLE - A vehicle includes an engine, an engine cooling system configured to cool the engine with a coolant, an air conditioning apparatus, a heat exchanger that exchanges heat between the coolant and a refrigerant, and an ECU that controls the air conditioning apparatus. The air conditioning apparatus includes a compressor that compresses the refrigerant, and the compressor is driven in response to an air conditioning request to air condition a passenger compartment. Even in the absence of the air conditioning request, the ECU causes the compressor to be driven to heat the coolant by radiation of heat from the refrigerant. | 10-22-2015 |

20150099443 | VEHICLE COMPRISING AIR CONDITIONING APPARATUS - A vehicle includes an air conditioning apparatus configured to be capable of executing ventilation operation to supply air outside the vehicle into a passenger compartment, and cooling operation to supply cool air into the passenger compartment; and a control unit that causes the air conditioning apparatus to execute remote air conditioning in which air conditioning is performed while a user is not in the vehicle, and operated air conditioning in which air conditioning is performed by the user's operation while the user is in the vehicle. The control unit controls the air conditioning apparatus such that a condition in which the ventilation operation is executed in the remote air conditioning is more relaxed than a condition in which the ventilation operation is executed in the operated air conditioning. In this way, power consumption by pre-air conditioning can be reduced. | 04-09-2015 |
20150102118 | HYBRID VEHICLE - When an A/C switch is ON and a predetermined dehumidification condition is met, an ECU determines whether or not HV travel is selected. When the HV travel is selected, the ECU controls an air conditioning facility so that a heat pump cycle performs a cooling operation (dehumidification) and hot-water heating is used for the heating capability. When the EV travel is selected, the ECU controls the air conditioning facility so that the heat pump cycle performs dehumidification heating. | 04-16-2015 |
