る。In the drive unit shown in FIG. 2, since the gear coupling 2 and the gear unit 3 use gears, they cannot rotate smoothly unless backlash is applied. In particular, in the coasting state of the electric vehicle, the gear coupling and the gear device have no load, and the gear has play due to the amount of the pack crush. Here, when a rotational force is generated in such a gear joint or gear device due to the vibration received from the rail or the like, the rotation angle becomes larger and the vibration also becomes larger than that at the time of power running and regeneration with a load corresponding to the clearance of the backlash. Had a problem. The object of the present invention is to eliminate such a problem by applying an appropriate torque to the drive device enclosure during coasting,
It is to provide a special control method that prevents the occurrence of vibration.
