摘要:
A power window apparatus for carrying out a safety control operation when an object is caught in the window, which apparatus is capable of setting a safety control mode disabling region to within the required distance exactly. The power window apparatus includes a motor rotation sensor for sensing a state of rotation of the motor, and a window movement sensor for sensing the amount of movement of the window. The object-caught state is detected on the basis of the rotational rate of the motor, and the absolute position of the window is detected on the basis of the detected amount of movement of the window. The safety control mode is disabled in response to the detected absolute position of the window. A reference value for detecting the object-caught state may be varied as the window approaches its fully closed position.

A power window apparatus with a safety device capable of taking a safety measure when it detects the neck or hand of a passenger being caught in the window, which device can exactly detect such a dangerous state and take a reliable safety measure to correct for the same, irrespective of variations of ambient temperature. A temperature sensor provided which senses the temperature of the motor acting as a drive source for moving the window. This temperature is closely related to the ambient temperature. A reference value for the motor speed for detecting an object-caught state is altered according to the detected temperature, thereby providing exact detection of the object-caught state irrespective of temperature variations. Preferably, the power transmission for the window, the temperature sensor, and a controller structure are mounted on an inner side of a single housing.

A safety device for a power window which, if one's hand or neck is caught between the window glass and the sash, detects such state instantaneously and accurately to perform a safety control operation. Respective detectors detect the absolute and relative speeds of a power window opening or closing operation to determine whether or not a foreign object is caught in the window. When at least one of the detectors detects a foreign object being caught in the window, a safety control operation is carried out, for instance, stopping the movement of the window glass. Since the absolute speed and the relative speed are utilized in combination, a dangerous state can be detected instantaneously and accurately. Also, backlash in the drive mechanism for the window can be detected, and the safety control operation inhibited during such times to prevent erroneously effecting a safety control operation.

A safety control power window device which reliably detects nipping of a finger by a window and sash and which is little influenced by variations of motor characteristics of the motor used as a drive source of the power window device. The window position and a thrust pressure acting on the rotary shaft of the motor providing the force for opening and closing the window are detected. Reference pressures for detecting nipping are set according to the window position detected. By comparing the detected pressure and the reference pressures, nipping by the window is detected. Since nipping and the window position are not detected using the drive current of the motor, accurate safety control is realized, eliminating influences caused by variations of the characteristics of the motor.
摘要:
A method for operating power window apparatus with a safety device which stops the closing operation of the window in response to the detection of an object-caught state, which prevents the incomplete close of the window, and can accurately detect the object-caught state. The opening/closing position of the window is detected by counting pulses generated as the window moves. A region where a safety control can be carried out is determined on the basis of the detected opening/closing position. When the window reaches a position near a position where the window is fully closed, the count indicative of the opening/closing position detector is reset. The resetting operation is carried out so that a time point where the relative speed of the window is reduced is set at the fully closed position of the window.

In a process in which a current is supplied from a switching regulator to multi-chip LEDs, the forward voltages of the LEDs are respectively detected in forward detecting circuits. The detected values are sent to a microcomputer. In the microcomputer, detected values when the multi-chip LEDs are initially turned on are stored as initial values. A first abnormality deciding value is set from the initial value. The detected values are sequentially stored as updated values. Second abnormality deciding values having conditions stricter than those of the first abnormality deciding value are sequentially set in accordance with the stored updated value. A read value is compared with the first abnormality deciding value or the read value is compared with the second abnormality deciding value to decide whether or not the abnormality of the LEDs is present. When it is decided that the LEDs are abnormal, an LED is turned on to inform a driver of the presence of the abnormality.

In a lighting circuit, a lighting control circuit of a discharge lamp and a starting circuit for supplying a starting pulse to the discharge lamp are provided and also, electric power and the starting pulse are supplied through a socket connected to the discharge lamp. The starting circuit provided within the socket has a transformer, a capacitor connected to a primary winding of the transformer and a self-breakdown type switch element. It is constructed so that a feeding path to the capacitor is formed to charge the capacitor only when the discharge lamp is connected to the socket and a connection between a first terminal and a third terminal is made.
