A vehicle air conditioner allows storing cold thermal energy in a cold thermal energy storage unit during operation of a vehicle engine to be used later during an eco-run mode of a hybrid vehicle. Vehicle cabin air is cooled by the cold thermal energy quantity of a cold thermal energy storage unit when the vehicle engine is stopped and cold air continues to be requested by passengers. During engine operation, the cold thermal energy storage time, which is the time it takes for the temperature of the cold thermal energy storage unit to reach the solidifying point of the cold thermal energy storage material or lower, is measured. The stored cold thermal energy quantity of the cold thermal energy storage material during the operation of the vehicle engine is calculated based on information including the cold thermal energy storage time and cold air volumes.

The method as in claim 1, wherein said respective synchronized final spinning-in step is synchronize with completion of said closing step. 3. The method as in claim 1, wherein said respective synchronized final spinning-in step is synchronize with start of said closing step. 4. The method as in claim 1, wherein said respective synchronized final spinning-in step is synchronized to start with the time interval between start and completion of said closing step. 5. The method as in claim 1, wherein the yarn preparation steps and spinning rotor preparation steps are carried out manually, and the final spinning-in steps are automatically initiated by a control unit and carried out by operating components of the spinning unit. 6. The method as in claim 1, wherein the yarn preparation steps and spinning rotor preparation steps except the closing of the spinning unit step are carried out manually, and the final spinning-in steps are automatically initiated by a control unit and carried out by operating components of the spinning unit, said closing of the spinning unit started by a command issued by the control unit. 7. The method as in claim 1, wherein the yarn preparation steps and spinning rotor preparation steps are carried out by an attending device, and the final spinning-in steps are automatically initiated by a control unit and carried out by operating components of the spinning unit. 8. The method as in claim 1, wherein the yarn preparation steps and spinning rotor preparation steps except the closing of the spinning unit step are carried out by an attending device, and the final spinning-in steps are carried out by operating components of the spinning unit, the step of closing the spinning unit being started by a command from the attending device and the final spinning-in steps being started by the step of closing the spinning unit. 9. A method of spinning-in yarn at a spinning unit of a rotor spinning machine, said method comprising: steps of yarn preparation, steps of spinning rotor preparation, and final spinning-in steps; said steps of yarn preparation comprising detection of a yarn end on a bobbin or preparation of an auxiliary yarn if spinning-in on an empty tube, unwinding and metering a yarn length required for the spinning-in, placing the yarn into a path in which it is unclamped by rollers of a yarn draw-off mechanism, and introducing the yarn end into a yarn delivery tube extending from a spinning rotor; said steps of spinning rotor preparation comprising opening the spinning unit from its operative spinning position to a cleaning position, cleaning the spinning rotor in a stopped position thereof, and closing the spinning unit to its operative spinning position; said final spinning-in steps comprising starting sliver supply to a fiber singling-out device, leading singled-our fibers from the singling-out device away from the spinning rotor for a predetermined time interval, bringing the yarn end into contact with a collecting groove in the spinning rotor, and starting yarn draw off and winding; and wherein at least one of said final spinning-in steps is synchronized with said closing of the spinning u
