Methods of and systems for dual drive HVAC compressor controls in automotive vehicles |
摘要 |
The efficiency of a dual drive compressor for an air conditioner in a hybrid vehicle having an internal combustion engine and an electric motor is enhanced by calculating compressor load for the air conditioner and then determining allowable engine-off time for the internal combustion engine. Once the engine is turned off, a time counter is started. The engine is thereafter turned on once the time counter indicates that an allowable engine-off time has elapsed. During the cycle, the engine is forced to remain on until minimum "engine-on" time has elapsed. The A/C compressor load is calculated using compressor capacity, engine speed, and/or air conditioner high pressure as input parameters.
