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 may improve vehicle acceleration response while at the same time providing cooling capacity to a vehicle cabin.
Claims20
A method for controlling an air conditioner compressor of a vehicle, comprising:
- adjusting a load that an air conditioner compressor applies to an energy conversion device in response to a difference between an available torque from the energy conversion device and load demands of the energy conversion device while continuing to provide an air conditioning cooling capacity to an air conditioner evaporator.
A method for controlling an air conditioner compressor of a vehicle, comprising:
- providing an amount of torque to an air conditioner compressor that is equal to or less than a torque that provides full compressor output capacity in a first mode;
- and
- providing less than an amount torque to operate the air conditioner compressor at full compressor output capacity in a second mode in response to a difference between an available torque from an energy conversion device and load demands of the energy conversion device while continuing to provide air conditioning cooling capacity to an air conditioner evaporator.
A system for controlling an air conditioner of a vehicle, comprising:
- an energy conversion device;
- an air conditioner compressor including a piston, a variable displacement control valve for adjusting a stroke of the piston, and a clutch where the air conditioner compressor selectively coupled to the energy conversion device via the clutch;
- and
- a controller including instructions for adjusting the stroke of the piston in response to a difference between an available torque from the energy conversion device and load demands of the energy conversion device while continuing to provide air conditioning cooling capacity to an air conditioner evaporator.
