Method for controlling coupling device depending on speed of motor of motor vehicle between primary condition and secondary condition, involves transferring torque by coupling motor with cooling agent compressor by coupling device

摘要

The method involves transferring torque by coupling a motor with a cooling agent compressor by a coupling device in primary condition. The coupling device decouples the motor and the cooling agent compressor from each other in a secondary condition. The operating parameter values (D1,D2,B1 to B19) are detected by a controller and the coupling device is controlled depending on the speed. An independent claim is included for an air conditioning system comprises a controllable coupling device.
