Abstract
Embodiments are disclosed that relate to controlling a compressor. In one example, method of controlling a compressor comprises regulating a discharge capacity of the compressor via a control current supplied to a control device, holding the control current supplied to the control device at substantially zero amperes for a first duration, and stepping the control current from substantially zero amperes to a sustainable current that provides a sustainable level of a performance parameter of the compressor.

A method of controlling a compressor, comprising:
- regulating a discharge capacity of the compressor via a control current supplied to a control device;
- holding the control current supplied to the control device at substantially zero amperes for a first duration;
- and
- stepping the control current from substantially zero amperes to a sustainable current that provides a sustainable level of a performance parameter of the compressor.
A system for controlling a compressor, comprising:
- a compressor;
- and
- a control device configured to regulate a discharge capacity of the compressor via a control current supplied to the control device;
- wherein the control current is held at substantially zero amperes for a first duration and is then stepped up to a sustainable current that provides a sustainable level of a performance parameter of the compressor.
A method of operating a compressor of a motor vehicle air conditioning system, comprising:
- holding a current supplied to the compressor to a minimum current in response to a request to reduce engine load;
- stepping up the current from the minimum current to a sustainable current in response to cessation of the request;
- and
- increasing the current from the sustainable current to an operational current.
