This disclosure relates to a vehicle configured to detect a low refrigerant charge and a corresponding method. In some aspects, the techniques described herein relate to a vehicle, including: a thermal conditioning system including a compressor and a suction pressure sensor upstream of the compressor; and a controller in communication with the compressor and the suction pressure sensor, wherein the controller is configured to perform a technique to monitor for a low charge condition, and the controller is configured to inhibit a low pressure cutoff when the controller is performing technique.

Vehicle configured to detect low refrigerant charge

A system and method for protecting against low refrigerant charge of a refrigerant subsystem in a vehicle includes a controller configured to control a component of the vehicle in response to detecting a low refrigerant charge based on an ambient temperature of the refrigerant subsystem, a suction pressure of refrigerant entering a compressor of the refrigerant subsystem, and a speed of the compressor.
