<P>PROBLEM TO BE SOLVED: To enhance operation accuracy of a vehicular automatic opening-closing device by accurately detecting operation of an opening-closing body. <P>SOLUTION: A control device 31 is connected to an electric motor 25 for driving opening-closing of a sliding door 13, and operation of the electric motor 25 is controlled by this control device 31. An acceleration sensor 33 is arranged in the sliding door 13, and nipping and falling of the sliding door 13 are detected on the basis of acceleration α of the sliding door 13 detected by this acceleration sensor 33. A moving speed (v) of the sliding door is calculated by integrating the acceleration α by time, and a speed of the sliding door 13 is controlled on the basis of this moving speed (v). A door position (p) of the sliding door 13 is also calculated by further integrating the calculated moving sped (v) by the time, and operation of the sliding door 13 is controlled on the basis of this door position (p). <P>COPYRIGHT: (C)2008,JPO&INPIT |
