车窗升降控制器的防夹测控算法

he window lift drive system model and parameters of calculation are given, and modeling and calculation parameters for the motor - Turbo worm reducer - rotating linear transformation - the windows lift track system architecture, in particular given the expression of Hall pulse－distance of windows lift. The system architectures are given based the current detection method, the current ripple detection method, the acceleration detection method of rotation pulse and the hybrid algorithm. By comparing the advantages and disadvantages of various algorithms and systems are shown.
