  • Publication number: 20150234536
    Abstract: An input apparatus includes a central operation unit and a controller that controls an input operation to the central operation unit. The controller includes a determination unit that determines whether the central operation unit is going to be operated from, at least, a left side of the central operation unit or a right side thereof and a reference change unit that changes an operation reference direction of the operation unit in plan view in accordance with a determination result of the determination unit. When it is determined that the operation unit is going to be operated by a driver, the operation reference direction is changed to another direction. When it is determined that the operation unit is going to be operated by a passenger on a passenger seat, the operation reference direction is changed to still another direction.

  • Patent number: 6580241
    Abstract: 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.

  • Patent number: 6563279
    Abstract: 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.

  • Patent number: 6531840
    Abstract: A power window apparatus and a method for controlling the same is provided in which the whole travel region of a window is divided into a plurality of blocks, a reference value of a motor torque value, a tolerance value for tolerating a fluctuation in the motor torque value, and a determination value obtained by adding the reference value and the tolerance value for determining pinching are set and stored for each block and, when the torque value detected is larger than the reference value, a correction value in proportion to the difference is added to the determination value so as to perform the next determination.

  • Publication number: 20020014871
    Abstract: 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.
