Abstract
A compressor control apparatus for a vehicle includes: a compressor configured to compress coolant of an air conditioner; a coolant temperature measurement unit configured to measure a coolant temperature; a data detector configured to detect state data for controlling the compressor; and a controller configured to determine an operation rate of the compressor based on the coolant temperature and the state data, and operate the compressor based on the operation rate of the compressor.
Claims13
A compressor control apparatus for a vehicle, comprising:
- a compressor configured to compress coolant of an air conditioner;
- a coolant temperature measurement unit configured to measure a coolant temperature;
- a data detector configured to detect state data for controlling the compressor;
- and
- a controller configured to determine an operation rate of the compressor based on the coolant temperature and the state data, and operate the compressor based on the operation rate of the compressor,
- wherein when the state data satisfy a worst stress condition, the controller determines whether the coolant temperature is equal to or more than a first reference value, and
- when the coolant temperature is equal to or more than the first reference value, the controller lowers the operation rate of the compressor.
A compressor control method for a vehicle, comprising the steps of:
- detecting, by a controller, state data when an air conditioner is turned on;
- determining, by the controller, whether the state data satisfy a worst stress condition;
- comparing, by the controller, a coolant temperature to a first reference value, when the state data satisfy the worst stress condition;
- lowering, by the controller, an operation rate of a compressor when the coolant temperature is equal to or more than the first reference value;
- and
- operating, by the controller, the compressor based on the operation rate.
A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:
- program instructions that detect state data when an air conditioner is turned on;
- program instructions that determine whether the state data satisfy a worst stress condition;
- program instructions that compare a coolant temperature to a first reference value, when the state data satisfy the worst stress condition;
- program instructions that lower an operation rate of a compressor when the coolant temperature is equal to or more than the first reference value;
- and
- program instructions that operate the compressor based on the operation rate.
