VEHICLE DOOR SYSTEM CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide a vehicle door system control device capable of determining the presence of a user's control command operation to a vehicle door without erroneous detection. SOLUTION: The vehicle door system control device 1 for controlling a vehicle door system 40 comprises a vibration detecting sensor 20 detecting vibration applied to the vehicle door by the user; a peak hold section 32 storing a peak value of detection signals; a threshold storage section 36 storing a determination threshold; a threshold updating section 34 updating the determination threshold stored in the threshold storage section 36 after the lapse of a preset first set time based on the variation in the case of newly detecting a peak value not larger than the determination threshold but larger than the peak value stored in the peak hold section 32; and a determining section 37 determining that the vibration is caused by the control command operation in the case of detecting a detection signal larger than the determination threshold.
