Vehicle window lift control system and control method

A vehicle window lift control system for controlling lifting up or lowering down of a vehicle window, the vehicle window lift control system comprising:

• a window lift motor which is a brushless direct current motor;
• an inverter;
• a rotor position sensing unit;
• a motor drive/control module configured to drive the inverter to enable an operation of the window lift motor based on a rotor position feedback signal obtained by the rotor position sensing unit;
• and
• an anti-pinch module comprising:
• a pulse counter configured to record the number of pulses generated by the rotor position sensing unit during lifting up of the vehicle window;
• a count comparator configured to compare the recorded number of the pulses against a preset threshold to deteimine whether or not the vehicle window is in an anti-pinch area;
• an obstacle judgment unit configured to be initiated when it is determined that the vehicle window is in the anti-pinch area;
• and
• an anti-pinch instruction unit configured to send an anti-pinch instruction to the motor drive/control module when the obstacle judgment unit determines that there is an obstacle, and the motor drive/control module configured to drive the inverter according to the anti-pinch instruction to make the motor rotate reversely.
