If it is determined in step S12 that the operation time Tr is equal to or longer than the speed determination time Tj, the electric motor 21 is stopped in step S13, and then, in step S14, the electromagnetic clutch 3 1 Is switched to the cutoff state. In other words, as shown in FIG. 8, depending on the electric motor 21 operating in the low driving force mode, the sliding door 3 moves within the speed judgment time Tj in either the opening direction or the closing direction.
- the vehicle 1 determines that the vehicle 1 is horizontal, that is, the slide door 3 does not move due to its own weight, and the slide door 3 is kept at the intermediate position. That is, the electromagnetic clutch 31 is switched to the disconnected state. If it is determined in step S12 that the operation time Tr is shorter than the speed determination time Tj, the process returns to step S9, and the moving speed V0 of the slide door 3 is again increased to the movable speed V ⁇ or more. Is determined. As described above, depending on the low driving force mode, when the moving speeds Vc and Vo of the sliding door 3 in both the closing direction and the opening direction do not become higher than the movable speed Va within a predetermined time, the electric motor is driven.
- the slide door 3 can be stopped at the intermediate position when the vehicle 1 is horizontal.
