A control apparatus for a movable vehicle roof panel determines the position of the panel in a tilt open state and evaluates whether the panel is in normal tilt-open range of positions or has, via inertia, traveled beyond those normal positions. The control apparatus allows movement to the closed position if movement beyond a permissible range has been achieved through roof panel inertia.

Controller for a moving member and method for setting a reference position of the moving member

A control apparatus rotates a drive motor reversely to reverse the moving direction of a roof glass when movement of the roof glass is obstructed by a foreign matter caught between the roof glass and a frame while the roof glass is moving toward the closing position, sets a home position of the roof glass by setting the count number to a predetermined value with the roof glass placed in a predetermined position. The control apparatus performs setting of the home position again when a reverse action of the roof glass has been carried out, because of catching of the foreign matter in the roof glass, a number of times equal to or greater than a specified number. An abnormality detecting device detects an abnormality in which the reverse action of the roof glass is not carried out within a specified time period. When the abnormality is detected, the control apparatus avoids setting the home position again.

Controller for a moving member including an abnormality detecting device

A control unit stores a count value, which is used to detect an operational position of a roof glass, in a RAM. The control unit determines whether the count value is properly stored in the RAM when a voltage of a power supply falls below a predetermined voltage and thereafter returns to the predetermined voltage. Even in a case where the control unit determines that the count value is properly stored in the RAM, the control unit determines there is a possibility of having a deviation between an actual operational position of the roof glass and the count value. Thereafter, the control unit resets a reference point of the roof glass.

Closure member control device and method for limiting positional deviation of closure member

A sunroof apparatus comprises a drive motor which actuates a roof glass and a control section. The control section rotates the drive motor reversely when the movement of the sunroof is obstructed by a caught foreign matter. When a drive voltage to be supplied to the drive motor becomes lower than a reference voltage, the control section determines that the drive voltage is abnormal and stops supplying the drive voltage to the drive motor to inhibit the drive motor from being operated. A first reference voltage is used as the reference voltage at the time the drive motor is stopped, and a second reference voltage lower than the first reference voltage is used as the reference voltage at the time the drive motor is operated. It is therefore possible to detect a foreign matter being caught before an abnormality of the drive voltage is determined.
