Vehicle door control device
A vehicle door control device controlling a motor and a door lock device of a door. During a closing operation of the door based on a closing operation command signal, the motor is driven to cause the door to perform the closing operation until shift of a latch mechanism from the unlatching state to the half-latching state is detected. The latch mechanism is shifted from the half-latching state to the full-latching state by starting driving of the door lock device simultaneously with or before or after completion of the closing operation of the door. When the shift of the latch mechanism from the half-latching state to the full-latching state is detected, position correction control of correcting a position of the door by driving the motor such that a force in an opening direction acts on the door is executed.
1 . A vehicle door control device that is applied to a vehicle,
the vehicle including:
a door configured to open and close a door opening of a vehicle body by rotating about a rotation axis extending along an upper edge of the door opening;
a drive device including a motor configured to drive the door to open and close; and
a door lock device configured to change a restraint state of the door with respect to the vehicle body,
the vehicle door control device controlling driving of the motor and driving of the door lock device, wherein
the door lock device includes a latch mechanism configured to shift among a full-latching state in which the door is restrained to the vehicle body at a fully-closed position, a half-latching state in which the door is restrained to the vehicle body at a half-closed position, and an unlatching state in which the door is not restrained to the vehicle body,
during a closing operation of the door based on a closing operation command signal, the motor is driven to cause the door to perform the closing operation until shift of the latch mechanism from the unlatching state to the half-latching state is detected,
the latch mechanism is shifted from the half-latching state to the full-latching state by starting driving of the door lock device simultaneously with or before or after completion of the closing operation of the door, and
when a completion of the shift of the latch mechanism from the half-latching state to the full-latching state is detected, position correction control of correcting a position of the door by driving the motor such that a force in an opening direction acts on the door in the fully-closed position is executed.
2 . The vehicle door control device according to claim 1 , wherein
the vehicle includes a weather strip fixed to an outer peripheral portion of the door opening to seal between the vehicle body and the door, and
when the shift of the latch mechanism from the unlatching state to the half-latching state is detected, braking control of applying a braking force to the door by regenerative braking action of the motor is executed.
3 . The vehicle door control device according to claim 2 , wherein
even when the shift of the latch mechanism from the half-latching state to the full-latching state is detected, execution of the braking control is continued until a predetermined period of time elapses since the latch mechanism shifts from the unlatching state to the half-latching state.
4 . The vehicle door control device according to claim 1 , wherein
a first voltage applied to the motor in the position correction control is less than a second voltage applied to the motor in the closing operation.
