VEHICLE DOOR CONTROL DEVICE
A vehicle door control device applied to a vehicle including a swingably supported door and a door braking unit applying a braking force to the door includes: a braking control unit that executes a first braking processing of holding the braking force at a reference braking force for stopping the door and ending when an external force acting on the door is larger than the braking force, and a second braking processing of gradually increasing the braking force from the reference braking force after the first braking processing. The braking control unit executes, during execution of the second braking processing, a processing of eliminating the braking force when a situation where the external force is larger than the braking force continues, and executes a third braking processing of holding the braking force to be equal to or larger than the reference braking force when the situation does not continue.
1 . A vehicle door control device configured to be applied to a vehicle including a door that is swingably supported and a door braking unit that applies a braking force to the door, the vehicle door control device comprising:
a braking control unit configured to execute a first braking processing of holding the braking force at a reference braking force for stopping the door and ending when an external force acting on the door is larger than the braking force, and a second braking processing of gradually increasing the braking force from the reference braking force after the first braking processing, wherein
the braking control unit executes, during execution of the second braking processing, a braking force eliminating processing of eliminating the braking force when a situation in which the external force is larger than the braking force continues, and executes a third braking processing of holding the braking force to be equal to or larger than the reference braking force when the situation in which the external force is larger than the braking force does not continue.
2 . The vehicle door control device according to claim 1 , wherein
the braking control unit gradually reduces the braking force in the braking force eliminating processing.
3 . The vehicle door control device according to claim 1 , wherein
during the execution of the second braking processing, in the situation in which the external force is larger than the braking force continues, the braking control unit executes the braking force eliminating processing when an increment of the external force per unit time is less than an upper limit determination value, and executes the third braking processing when the increment of the external force per unit time is equal to or larger than the upper limit determination value.
4 . The vehicle door control device according to claim 1 , wherein
the vehicle includes a door driving unit including a motor serving as a drive source that opens and closes the door,
the vehicle door control device further comprises a drive control unit that opens and closes the door by controlling the door driving unit, and
during execution of the first braking processing and the second braking processing, the braking control unit determines that the external force is larger than the braking force when a rotation amount of the motor increases and determines that the external force is equal to or smaller than the braking force when the rotation amount of the motor does not increase.
