An apparatus that controls opening and closing of a roof glass is disclosed. The apparatus includes a drive motor that is actuated to selectively open and close the roof glass. The apparatus stores a count value that changes in correspondence with operation of the drive motor. The apparatus detects the number of cycles of reset starting and determines whether the detected number of the reset starting cycles is in a predetermined acceptable range. The apparatus switches initial setting, in accordance with which the relative relationship between the actual open/closed position of the roof glass and the count value is determined, to a non-set state if it is determined that the number of the reset starting cycles exceeds the acceptable range.

Control apparatus for open/close member and method for controlling open/close member

A control apparatus for a power window device stores a speed control start position that is set between a fully open position and a fully closed position, and a speed control end position that is set adjacently to the fully open position. While driving a windowpane in a direction toward the fully open position, the control apparatus reduces a motor output after the windowpane reaches the speed control start position until it reaches the speed control end position. The control apparatus de-energizes a motor when the windowpane reaches the speed control end position. The speed control end position is set at a position, from which the windowpane cannot reach the fully open position with its movement speed at the time the motor is de-energized.

Opening/closing member control apparatus and method

A controller for controlling a sliding roof sets, as an operating area, a predetermined range in the sunroof slidable range and controls a motor driving the sliding roof such that the sliding roof slides in the operating area. When the sliding roof stops near a sliding lock end, the stop position is stored on an assumption that the positional deviation would occur. The sliding roof slides again from the stop position. Based on whether a traveling distance from the stop position to the sliding roof comes into contact with the tilt lock end is longer than the sunroof slidable range, the positional deviation is determined. It is possible to accurately determine whether the sliding member is locked and stopped by positional deviation or the intrusion of foreign object.

Sliding member controller

An opening and closing member control system includes a rotation sensing device, which outputs a pulse signal synchronously to a movement of a window glass, and a controller, which senses pinching of an object by an opening and closing member based on the pulse signal. The controller has leaning stored data &#x394;&#x3c9;based on the pulse signal. The controller computes a rotational speed difference &#x394;&#x3c9; at a current position of the window glass based on the pulse signal while the window glass is driven in a closing direction. The controller computes a difference between the rotational speed difference &#x394;&#x3c9; and leaning stored data &#x394;&#x3c9;in such a manner that the controller determines whether the pinching of the object based on a comparison between the difference and a pinching determining threshold value &#x3b2;.

Opening and closing member control system

A power window device includes window glass, an elevating mechanism, and a control device for detecting pinching of a foreign object by the window glass. The control device calculates an amount (a rotation speed variation &#x3a3;&#x394;&#x3c9;) of the pinching based on a variation amount of an opening/closing speed of the window glass, and estimates the amount (a rotation speed variation &#x3a3;&#x394;&#x3c9;) of the pinching before the opening/closing speed changes due to the pinching. The control device determines the pinching of the foreign object based on these pinching calculation and estimation amounts.

Opening/closing member control apparatus and method for detecting pinching

A panel member control system for controlling a panel member includes a motor, a rotation detecting means, and a pinching detecting means. The rotation detecting means detects a rotational speed of the motor. The pinching detecting means detects an occurrence of pinching of an object by the panel member when a pinching indicative value exceeds a pinching determination threshold. The pinching detecting means includes a disturbance detecting means and a correcting means. The disturbance detecting means determines whether the motor is in a disturbed state based on a change in the rotational speed. The correcting means corrects the pinching determination threshold in view of a result of the determination made by the disturbance detecting means.

Panel member control system

A motor controller includes: a motor control part for driving and controlling a motor; an estimated temperature computing part for computing an estimated temperature of a winding of the motor; and a motor protecting part for protecting the motor from being burned when the estimated temperature becomes larger than a predetermined temperature. A temperature rise value of the estimated temperature is computed according to operating conditions of the motor at the time of passing electric current through the winding. This temperature rise value is added to an estimated temperature stored in the estimated temperature storing part to update the estimate temperature. To compute the temperature rise value, an optimum temperature rise value is computed by the use of a plurality of temperature-rise value computing expressions.

Motor controller

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 motor drives a window glass of a door of a vehicle in an opening direction and a closing direction. A rotation sensing device outputs a pulse signal in response to rotation of the motor. A controller senses pinching of an object by the window glass based on the rotational speed signal. Specifically, the controller computes a rate of change in the rotational speed, i.e., a rotational speed difference based on the rotational speed signal. The controller senses start of the pinching based on the rotational speed difference. When an amount of change in the rotational speed since the time of sensing the start of the pinching exceeds a pinching determining threshold value, the controller confirm the pinching of the object.

A control apparatus for a closure device includes pinch detector for detecting a foreign body being pinched by an opening/closing member when the variation degree of a movement of the opening/closing member reaches a predetermined threshold value. When this control apparatus for a closure device determines that a vehicle is running, the threshold value is set at a second threshold value, which is reduced in a detection sensitivity of pinch as compared with a first threshold value set when the vehicle is stationary. When the apparatus detects that a load not smaller than a predetermined value is applied by disturbance to the opening/closing member in a closing direction, the threshold value is set at a third threshold value, which is reduced in the detection sensitivity of pinch as compared with the second threshold value.

Control apparatus for closure device

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.
