Abstract
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.
Claims6
A sunroof control apparatus comprising:
- a roof glass which is so provided as to be slidable along a skylight of a vehicle and tiltable about one axial line and is placeable in a fully-closed position where said skylight is fully closed, a tilt fully-open position where one side of said skylight is opened as one side of said roof glass is placed outside said vehicle by a tilt action of said roof glass, and a fully-open position where said skylight is fully opened as said roof glass is moved along said skylight;
- a drive motor for tilting and sliding said roof glass;
- a tilt switch which is operated to actuate said roof glass between said fully-closed position and said tilt fully-open position;
- a detecting device for detecting whether said drive motor is running;
- control means which controls said drive motor to actuate said roof glass based on an operation of said tilt switch and executes operations of:
- setting a tilt action permitting area in such a way as to include an area from said fully-closed position to said tilt fully-open position;
- and
- permitting a tilt action of said roof glass toward said fully-closed position based on said operation of said tilt switch, when a non-active state of said drive motor is detected in said tilt action permitting area while said roof glass is tilted to said tilt fully-open position from said fully-closed position and when said roof glass moves outward beyond said tilt action permitting area due to force of inertia.
A control method for a roof glass which, in accordance with actuation of a drive motor, is placeable in a fully-closed position where a skylight of a vehicle is fully closed, a tilt fully-open position where one side of said skylight is opened as one side of said roof glass is placed outside said vehicle by a tilt action of said roof glass and a fully-open position where said skylight is fully opened as said roof glass is moved along said skylight, a tilt action permitting area being set in such a way as to include an area from said fully-closed position to said tilt fully-open position, said method comprising the steps of:
- permitting a tilt action of said roof glass toward said fully-closed position based on said operation of a tilt switch, when a non-active state of said drive motor is detected in said tilt action permitting area while said roof glass is tilted to said tilt fully-open position from said fully-closed position and when said roof glass moves outward beyond said tilt action permitting area due to force of inertia.
