Patent number: 6580241Abstract: In a power window device an MCU detects motor torque values one by one when a window is opened and closed, compares the detected motor torque values with base values set to the travel regions and stops or reverses a motor determining that an object is pinched in the window when the former values exceed the latter values.Type: GrantFiled: October 25, 2000Date of Patent: June 17, 2003Assignee: Alps Electric Co., Ltd.Inventor: Takehito Sugawara

Patent number: 6563279Abstract: The present invention provides a power window system, by which it is possible to reliably detect that a foreign object is caught in a car window even during the period from the time of starting of a motor to the time when stable operation of the window is reached, and also, it is possible to minimize erroneous detection. The power window system of the present invention includes a pulse generator for generating repeated pulses in response to rotation of a motor, and a control unit for judging that a foreign object is caught in the window. The control unit divides the period of operation into three periods to match the characteristics during the starting of the power window system, i.e. a first period from the starting of the motor to the initiation of upward or downward movement of the window, a second period to the time point when the window reaches and maintains stable operation, and a third period after the second period.Type: GrantFiled: July 31, 2001Date of Patent: May 13, 2003Assignee: Alps Electric Co., Ltd.Inventor: Takehito Sugawara

Publication number: 20020014871Abstract: There are provided a power window apparatus and a method for controlling the same, which are less likely to cause malfunction to determine that pinching occurs when the pinching does not occur in the event that there occur a fluctuation in the motor torque value or a fluctuation in the coefficient of friction between the window and the window frame due to temperature changes, and an irregular variation in the pulse outputted owing to the shaved gear teeth of a pulse generation part 15 due to changes over time, so that the motor torque value detected is varied.Type: ApplicationFiled: July 23, 2001Publication date: February 7, 2002Applicant: Alps Electric Co., Ltd.Inventor: Takehito Sugawara
