System and method for controlling electric compressor for vehicle

A system for controlling an electric compressor of a vehicle, the system comprising:

• a user requirement setting apparatus;
• a vehicle velocity detection apparatus;
• an out-vehicle temperature detection apparatus;
• an in-vehicle temperature detection apparatus;
• a solar illumination detection apparatus;
• and
• a control apparatus;
• wherein the user requirement setting apparatus is configured to receive an air conditioner temperature and a blower step number set by a user;
• wherein the vehicle velocity detection apparatus is configured to detect a driving velocity of the vehicle;
• wherein the out-vehicle temperature detection apparatus is configured to detect a vehicle ambient temperature;
• wherein the in-vehicle temperature detection apparatus is configured to detect a vehicle internal temperature;
• wherein the solar illumination detection apparatus is configured to detect a solar illumination outside the vehicle and
• wherein the control apparatus is communicatively connected to the user requirement setting apparatus, the vehicle velocity detection apparatus, the out-vehicle temperature detection apparatus, the in-vehicle temperature detection apparatus, and the solar illumination detection apparatus, and is configured to:
• acquire the air conditioner temperature and the blower step number set by the user, the driving velocity of the vehicle, the vehicle ambient temperature, the solar illumination outside the vehicle, and the vehicle internal temperature;
• determine a rotation speed limitation rating of the electric compressor based on the air conditioner temperature and the blower step number set by the user;
• determine a final permitted vehicle velocity based on the vehicle ambient temperature, the solar illumination outside the vehicle, and the vehicle internal temperature;
• and
• compare the driving velocity of the vehicle and the final permitted vehicle velocity, and when the driving velocity of the vehicle is less than the final permitted vehicle velocity, determine a target electric compressor rotation speed according to the rotation speed limitation rating of the electric compressor to operate the electric compressor according to the target electric compressor rotation speed, wherein the control apparatus is further configured to:
• determine a cooling rating corresponding to the air conditioner temperature set by the user;
• determine a cooling rating corresponding to the blower step number set by the user;
• determine a cooling rating corresponding to a number of limitations of the electric compressor rotation speed;
• and
• determine the rotation speed limitation rating of the electric compressor based on the cooling rating corresponding to the air conditioner temperature set by the user, the cooling rating corresponding to the blower step number set by the user, and the cooling rating corresponding to the number of limitations of the electric compressor rotation speed.
