  • Patent number: 11255117
    Abstract: A control apparatus controlling an opening and closing member for a vehicle includes a drive control unit operating an opening and closing member of the vehicle by a motor serving as a drive source, and a catch detection unit detecting a catch of a foreign object caught by the opening and closing member in response to a current value of the motor. The drive control unit includes a motor control signal output unit outputting a motor control signal for supplying a drive power to the motor, and an advance-angle value setting unit setting an advance-angle value for advancing a phase of the motor control signal. The advance-angle value setting unit includes an advance-angle value increase prohibition unit prohibiting increase setting of the advance-angle value in a case where the current value of the motor reaches an advance-angle value increase prohibition current value.

  • 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.
