Vehicular opening/closing body control device and motor control device
A vehicular opening/closing body control device includes a braking control unit configured to apply a braking force to an opening/closing body by supplying driving power having a locked conduction phase to a motor, which is a drive source of the opening/closing body, wherein, when an execution time of phase-locked conduction control for locking the conduction phase and supplying the driving power reaches or exceeds a predetermined time, the braking control unit switches a conduction phase used for the phase-locked conduction control.
