Claim 0:
1. A heat pump system control method for a vehicle, the method comprising:
a process (A) of operating a compressor of an air conditioner to cool or heat an interior of the vehicle while the vehicle is driving, and measuring by a controller initial states of the compressor and a refrigerant based on data detected from a data detector, and monitoring the compressor;
a process (B) of determining by the controller whether a current coil temperature of a motor unit provided in the compressor is higher than a coil specification temperature through the process (A) and operating a protection mode; and
a process (C) of, when the process (B) is completed, calculating by the controller a slope of a coil temperature of the motor unit over time, determining whether the temperature slope is greater than zero (0) three times consecutively to stop the operation of the compressor, and terminating control.
