  • Patent number: 10883301
    Abstract: A control apparatus controlling an opening and closing member for a vehicle, the control apparatus includes a control signal output portion configured to output a motor control signal, and an advance angle value set portion configured to set an advance angle value, the advance angle value being for advancing a phase of the motor control signal when an assist opening and closing operation is performed. The control apparatus is configured to perform the automatic opening and closing operation which causes an opening and closing member to open and close automatically with driving force of the motor, and the assist opening and closing operation which causes the opening and closing member to open and close in such a manner that the driving force of the motor assists a manual operation force applied to the opening and closing member.

  • Patent number: 10787065
    Abstract: 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.
