Vehicle opening/closing body control device and opening/closing system for vehicle

A vehicle opening and closing body control device comprising:

• an opening and closing drive device, which performs an opening and closing operation of an opening and closing body of a vehicle;
• a fully opening lock, which holds the opening and closing body at a fully open position;
• an opening and closing body position detector, which detects a position of the opening and closing body;
• a trapping detector, which detects a trapping of a foreign object by the opening and closing body;
• and
• a controller, wherein
• when the opening and closing body is being opened,
• in a case where it is determined that the opening and closing body enters a stopped state in a fully open range between the fully open position and an assumed fully open position, which is shifted in the closing direction from the fully open position, the controller stops the opening and closing operation of the opening and closing body by the opening and closing drive device, and
• in a case where the opening and closing body moves in the closing direction from inside the fully open range and passes the assumed fully open position, the controller drives the opening and closing drive device to perform the closing operation of the opening and closing body, and
• when the opening and closing body is being closed, in a case where the position of the opening and closing body when the trapping of the foreign object is detected is in a reverse prohibiting range between the fully open position and a reverse prohibiting position, which is shifted in the closing direction from the assumed fully open position, the controller controls the operation of the opening and closing drive device to prevent the opening and closing body from being reversed and performing the opening operation.

A vehicle opening and closing body control device comprising:

• an opening and closing drive device, which performs an opening and closing operation of an opening and closing body of a vehicle;
• a fully opening lock, which holds the opening and closing body at a fully open position;
• an opening and closing body position detector, which detects a position of the opening and closing body;
• a trapping detector, which detects a trapping of a foreign object by the opening and closing body;
• an engagement and disengagement mechanism arranged in the opening and closing drive device to selectively engage and disengage drive power transmission between a motor serving as a drive source of the opening and closing drive device and the opening and closing body;
• and
• a controller, which controls operation of the opening and closing drive device,
• wherein, in a case where a trapping of a foreign object is detected when the opening and closing body moves in the closing direction without drive power supplied to the motor from a state in which the opening and closing body is stopped at an intermediate position in an operation range of the opening and closing body with the engagement and disengagement mechanism in an engaged state, in which the power drive transmission between the motor and the opening and closing body is permitted, the controller controls the operation of the opening and closing drive device to move the opening and closing body to the fully open position.

A vehicle opening and closing system comprising a vehicle opening and closing body control device, wherein the vehicle opening and closing body control device includes:

• an opening and closing drive device, which performs opening and closing operation of an opening and closing body of a vehicle;
• an opening and closing body position detector, which detects a position of the opening and closing body;
• a trapping detector, which detects a trapping of a foreign object by the opening and closing body;
• and
• a controller, which controls operation of the opening and closing drive device,
• wherein, when the opening and closing body is being closed,
• in a case where the position of the opening and closing body when the trapping of the foreign object is detected is outside a specified range between a fully closed position and a specified position, which is shifted in an opening direction from the fully closed position, the controller controls the operation of the opening and closing drive device to reverse the opening and closing body to perform the opening operation by a predetermined opening-and-returning distance and then stop the opening and closing body, and
• in a case where the position of the opening and closing body when the trapping of the foreign object is detected is in the specified range, the controller controls the operation of the opening and closing drive device to reverse the opening and closing body to perform the opening operation by the predetermined opening-and-returning distance or a greater distance and then stop the opening and closing body outside the specified range.
