Claims

[Claims for Utility Model Registration] 1. A motor-driven automobile window glass raising and lowering device, comprising a motor pulsing means for generating pulses related to the rotation angle as the motor rotates, and a motor for detecting the position of the window glass. means for counting pulses; means for calculating the rotation speed and speed fluctuation rate of the motor based on the motor pulse; and means for calculating the motor pulse based on the rotation speed and speed fluctuation rate of the motor and the position and moving direction of the window glass. An automatic lifting/lowering device for automobile window glass, characterized in that it comprises count correction means for correcting the contents of the means for counting, and means for monitoring the contents of the means for counting motor pulses and the motor speed fluctuation rate. . 2. In paragraph 1, the motor pulsating means shapes the pulsating current of the motor into a pulse waveform,
An automatic lifting and lowering device for automobile window glass, characterized in that the motor pulse is used as the motor pulse. 3 In paragraph 1, the count correction means:
Means for counting the motor pulses using a correction value searched from a data map prepared in advance based on the rotational speed and speed fluctuation rate of the motor, the position of the window glass, and the moving direction immediately before the command to operate the motor is canceled. An automatic lifting device for automobile window glass, characterized in that it corrects the contents of the window glass.
