ABSTRACT:
In a power window apparatus, an external force which develops at the time of catching foreign objects in a window is detected directly by a window frame sensor and indirectly by a motor load detection circuit. Automatic window closing operation is disabled when the external force exceeds a first and a second predetermined levels of the window frame sensor and the motor load detection circuit, respectively. When the window frame sensor fails, the window closing operation is disabled and a warning is provided at the time the external force detected by the load detection circuit reaches a third predetermined level. Alternatively, the automatic window closing operation is disabled when the external force exceeds the first or the second predetermined levels of the window frame sensor or the motor load detection circuit, respectively. When the window frame sensor fails, the window closing operation is disabled and the warning is provided at the time the external force reaches the second predetermined level. In each case, once the window frame sensor fails, the predetermined level used to determine a failure of the window frame sensor may be lowered so that the window closing operation may be disabled earlier.
