Definitions

  • a plurality of rollers 6 are provided, as shown by the dotted lines in Fig. 1 .
  • the rollers 6 roll while remaining in contact with the upper or lower surface of the guide rail 4.
  • a right rack gear 8R and a left rack gear 8L are provided and extend in the direction in which the guide rail 4 extends.
  • the right rack gear 8R is coupled with a right bracket 9R.
  • the movement causes the right bracket 9R to move in the left-right direction.
  • the left rack gear 8L is coupled with a left bracket 9L.
  • the left bracket 9L is coupled with the suspension device 5R.
  • the suspension device 5R and door leaf 3R integrally move in the left-right direction.
  • the left bracket 9L is coupled with the suspension device 5L.
  • the suspension device 5L and door leaf 3L integrally move in the left-right direction.
  • the power-supply voltage detecting unit 21 is configured to detect the level of the DC voltage output from the power supply unit 16.
  • the PWM control unit 22 is configured to generate a PWM signal for driving the motor 11 based on the level of the DC voltage detected by the power-supply voltage detecting unit 21 and the instruction signal from the instructing unit 19. More specifically, the PWM control unit 22 generates the PWM signal for controlling the duty ratio of the voltage to be fed to the motor 11, based on a reference voltage instruction pattern indicated by the instruction signal and the voltage level of the DC signal detected by the power-supply voltage detecting unit 21.
  • a Hall element 25 is provided in the vicinity of a rotational shaft 12 of the motor 11.
  • the Hall element 25 detects the number of rotations of the motor 11.
  • the motor monitoring unit 17 is provided in the vicinity of the motor 11.
  • the motor monitoring unit 17 includes, in addition to the above-mentioned Hall element 25, a motor current detector 26 for detecting the motor current and a motor voltage detector 27 for detecting the voltage applied to the motor 11.
  • the door pinch detection device 1 is configured to detect occurrence of door pinch between the leading edges of the door leaves 3R and 3L when the driving force from the motor 11 drives the door leaves 3R and 3L in the closing direction.
  • a door pinch detection device 1 relating to a second embodiment has the same block diagram configuration as shown in Fig. 4 , but performs a different series of steps than the door pinch detection device 1 relating to the first embodiment.
  • the threshold value may be defined as the value obtained by sorting by frequency the values of the motor current in the first period, specifying the most frequent value, and multiplying the most frequent value with a predetermined coefficient.
  • the threshold value may be defined as the value obtained by cumulatively adding together the values of the motor current in the first period to calculate the integrated value, and multiplying the integrated value with a predetermined coefficient. In this case, the coefficient is less than the coefficient used to calculate the threshold value based on the average value.
