  • the measurement value for each measurement is accumulated in the storage unit 108.
  • the measurement value output unit 103 supplies the measurement value to the prediction unit 115.
  • the prediction unit 115 reads, for example, the measurement value at the previous measurement from the storage unit 108, and predicts the timing at which the position adjustment of the sliding door 10 is necessary based on comparison between the measurement value at the previous measurement and the measurement value at the current measurement. For example, the prediction unit 115 obtains the temporal change amount of the measurement value based on the elapsed time from the previous measurement to the current measurement and the difference between the measurement value at the previous measurement and the measurement value at the current measurement. The prediction unit 115 predicts the timing by obtaining the time until the measurement value at the current measurement reaches a predetermined threshold based on the obtained temporal change amount.
  • the prediction unit 115 predicts the timing at which the position adjustment of the sliding door 10 is necessary based on the comparison between the measurement value acquired at a first time point and the measurement value acquired at a second time point earlier than the first time point. According to the present embodiment, the timing when the position adjustment of the sliding door 10 is necessary can be grasped.
  • the prediction is made based on the comparison between the measurement value at the previous measurement and the measurement value at the current measurement.
  • the measurement values may be those measured earlier than the measurement value at the current measurement.
  • the above prediction may be made based on comparison among three or more measurement values.
  • the present invention relates to a sliding door position adjustment assisting device and a sliding door position adjustment assisting system.
