Abstract
A vehicle door is operated in accordance with a desired speed pattern.A vehicle door opening-closing control device 1 includes a power-supply voltage detecting unit 2 that outputs a detection value of a power-supply voltage of an electric motor 13, a reference control pattern storage unit 3 that stores a reference control pattern that indicates a voltage command value or a speed command value for the electric motor 13, the reference control pattern is a control pattern of the electric motor when the detection value is within a predetermined range, a control pattern generating unit 4a that generates a corrected control pattern that is obtained by correcting the reference control pattern based on the detection value, and a PWM control unit 4 that controls the electric motor 13 based on the corrected control pattern.
