Opening and closing body control device

An opening and closing body control device, comprising:

• a drive unit that drives an opening and closing body that opens and closes an opening of a vehicle body;
• a distance detection unit that detects a detection distance that is a distance to a detected object around the opening and closing body;
• and
• a control unit that controls the drive unit to operate the opening and closing body when a start command of opening operation or closing operation of the opening and closing body is input,
• the control unit configured to:
• determine whether the detected object is a moving object or a stationary object based on a detection result of the distance detection unit when the start command is input;
• set a first collision determination distance as a collision determination distance to be compared with the detection distance in a case where the detected object is the stationary object;
• set a second collision determination distance longer than the first collision determination distance as the collision determination distance in a case where the detected object is the moving object;
• and
• control the drive unit to continue operation of the opening and closing body when the detection distance is larger than the collision determination distance, and control the drive unit to stop operation of the opening and closing body when the detection distance is smaller than the collision determination distance,
• wherein the control unit includes a storage unit that stores in advance a first table defining a correspondence relationship between an operation position of the opening and closing body and the first collision determination distance and a second table defining a correspondence relationship between the operation position and the second collision determination distance, and
• the control unit is further configured to:
• set the first collision determination distance according to the operation position with reference to the first table in a case where the detected object is the stationary object;
• and
• set the second collision determination distance according to the operation position with reference to the second table in a case where the detected object is the moving object,
• wherein the opening and closing body control device further comprises an opening and closing body position detection unit that detects the operation position of the opening and closing body,
• wherein the control unit sets the collision determination distance such that an excess amount of the second collision determination distance with respect to the first collision determination distance becomes larger as the operation position of the opening and closing body is closer to a maximum overhanging position where an overhanging amount of the opening and closing body from the vehicle body is at a maximum within a movable range of the opening and closing body.
