Abstract
A method for controlling torque of an air conditioner compressor is disclosed. In one example, the air conditioner compressor is a variable displacement compressor. The method may provide smooth transitions between different air conditioner compressor torques.
Claims16
A method for controlling an air conditioner compressor of a vehicle, comprising:
- adjusting an air conditioner compressor displacement command in response to an error between an expected air conditioner evaporator temperature and a measured or inferred air conditioner evaporator temperature.
9-14. (canceled)
A system for controlling an air conditioner of a vehicle, comprising:
- an air conditioner compressor including a piston and a variable displacement control valve for adjusting a stroke of the piston;
- and
- a controller including instructions for adjusting the stroke of the piston in response to an evaporator temperature error, the evaporator temperature error based on a difference between an expected evaporator temperature and a measured or inferred evaporator temperature.
