| 20120216557 | VEHICLE AIR CONDITIONING CONTROL SYSTEM - To determine whether or not integral control is performed when a requested compressor output value is limited by an upper or lower limit, based on an evaporator temperature deviation, prevent divergence of an integral value, and make an evaporator temperature follow a target evaporator temperature during the integral control, an evaporator temperature deviation calculation means, integral control means for calculating an integral value based on an evaporator temperature deviation, and output value calculation means for calculating a requested compressor output value based on the integral value and limiting the requested compressor output value to calculate a compressor output value are provided. | 08-30-2012 |
| 20120240608 | AIR-CONDITIONING CONTROL APPARATUS - An air-conditioning control apparatus performs detailed determination of the operating conditions of an air-conditioning apparatus, and performs efficient air-conditioning control such that power distribution is changed based on the detailed determination, in order to improve the comfort of occupants under a limitation on air-conditioning, thereby balancing ensuring the range with ensuring the comfort of the occupants. The air-conditioning control apparatus calculates usable power amounts for a cooling unit and a heating unit, and drives the cooling unit and the heating unit based on drive limit values. It allocates power amounts calculated for the condition of the battery and the vehicle drive, that can be allocated to the air-conditioning equipment, to the cooling unit and the heating unit according to an air-conditioning state that is set automatically or manually, thereby enabling necessary heating and cooling to be used to its full extent even during limitations on air-conditioning. | 09-27-2012 |

| 20130020045 | AIR CONDITIONING SYSTEM FOR AN ELECTRIC VEHICLE - There is provided an air conditioning system for a passenger compartment R of an electric vehicle having a rechargeable battery unit that is chargeable by supply of power from an external power source external to the vehicle. An air conditioner (AC) ECU | 01-24-2013 |
| 20130020046 | AUTOMOTIVE AIR CONDITIONING SYSTEM - An air conditioning system for a passenger compartment of an electric vehicle has a battery unit that is chargeable by supply of electric power from an external power source. The system includes a charge-level detection section to detect a charge level of the battery unit and an HEV controller has an integrated control of the whole of an electric vehicle including an air conditioner. Before a preparatory air-conditioning operation for air conditioning in the passenger compartment during charge, the HEV controller grants permission to enter air conditioning in the passenger compartment if the battery charge level is greater than a predetermined level. The HEV controller adjusts an amount of electric power usable for air conditioning in the passenger compartment based on a change in the charge level. | 01-24-2013 |
| 20130139532 | AIR CONDITIONER FOR VEHICLE - A controlling unit includes a fan air supply amount setting unit communicated with a supply fan feeding air cooled by an electric compressor into an interior of a vehicle and setting an air supply amount of the supply fan, and sets a rotation speed upper limit value of the electric compressor based on a vehicle speed detected by a vehicle speed detecting unit and the air supply amount set by the fan air supply amount setting unit. | 06-06-2013 |
| 20130160986 | AIR CONDITIONER FOR VEHICLE - An air conditioner for a vehicle equipped with a motor for driving the vehicle has a vehicle speed detecting unit, an electric compressor, an evaporator, an electric compressor rotation speed controlling unit, a controlling unit and a refrigerant pressure detecting unit. The controlling unit calculates a first candidate for a rotation speed upper limit value of the electric compressor based on a vehicle speed detected by the vehicle speed detecting unit, calculates a second candidate for the rotation speed upper limit value of the electric compressor based on a refrigerant pressure detected by the refrigerant pressure detecting unit, and decides a minimum value of the first and second candidates for the rotation speed upper limit value of the electric compressor, as the rotation speed upper limit value of the electric compressor. | 06-27-2013 |
| 20130292482 | AIR CONDITIONING SYSTEM FOR VEHICLES - In an air conditioning system, a control unit controls an adjusting unit to adjust a ratio between an amount of a first part of introduced air passing through a heater core and an amount of a second part of the introduced air bypassing the heater core to a first ratio at which the amount of the first part of the introduced air decreases from a maximized amount of the first part of the introduced air according to an increase in temperature of the heater core by a warming unit. When a setting temperature for air conditioning is increased by an input unit, the control unit controls the adjusting unit to change the ratio from the first ratio to a second ratio at which the amount of the first part of the introduced air increases. | 11-07-2013 |
