METHOD OF CONTROLLING VEHICLE AIR CONDITIONING AND VEHICLE AIR CONDITIONING DEVICE Russian patent published in 2020 - IPC B60H1/32 

FIELD: ventilation.

SUBSTANCE: invention relates to air conditioning devices. During the air conditioning control for the vehicle, in which the torque satisfying the vehicle drive torque total value and the air conditioning compressor drive torque is output to the engine, air conditioning compressor discharge tank is installed at minimum capacity at fuel shutoff in engine. When it is estimated that the discharge capacity must be changed from the minimum capacity in accordance with the condition inside the cabin, the discharge capacity varies from the minimum capacity to the upper limit of capacity allowed during normal operation, and after a predetermined time after the change, the discharge capacity changes from the upper limit of the capacity to the discharge capacity corresponding to the state inside the cabin.

EFFECT: stable deceleration is achieved, when compressor capacity is restored to normal capacity of compressor after it was minimized during fuel cut-off.
