  • Patent number: 7177741
    Abstract: A car-mounted device control system is obtained which can prevent or lessen erroneous operation of operating portions, switches, and the like during rotation of a steering wheel. When a CPU 16 starts up a function switching program from a storage medium 24 on the basis of an inputted touch signal, a present center control unit 10 compares a comparative rotational position R0 read from the storage medium 24 and a rotational position detection signal R from a steering angle sensor 32. As a result, when the rotational position detection signal R exceeds the comparative rotational position R0, a touch signal and a click signal are cancelled. Thus, inadvertent switching of functions due to a body touching a controller 70 while a steering wheel 22 is rotated can be prevented.

  • Patent number: 6882267
    Abstract: A device controller is provided which allows a vehicle occupant to confirm a device to be operated without looking an operation section. When a controller of a microswitch indicates a device such as a window regulator or a sun roof, a control circuit feeds a motion confirmation signal to a corresponding device such as a right-hand front door ECU and a roof ECU. A door glass, a sliding roof or the like then reciprocate slightly (i.e., in an amount that is enough for the vehicle occupant to visually confirm the reciprocation) via a window regulator driving circuit, a sun roof driving circuit or the like. The vehicle occupant can thereby confirm a device to be operated by the operation section without looking an operation section.

  • Patent number: 6707448
    Abstract: The present invention provides a touch control position determining method which allows the touch control position to be determined precisely regardless of the modes of control. When a touch control is made on an input pad, it is confirmed whether or not the upper and lower vertical position detecting lines are in the non-detected state in which infrared rays are not intercepted to determine whether the touch control position is located at the upper side, the center or the lower side (Steps 100 through 112). Next, it is confirmed whether or not the right and next horizontal position detecting lines are in the non-detected state to determine whether the touch control position along the horizontal direction is located at the left side, the center or the right side (Steps 114 through 122). Thus, the touch control position in the vertical and horizontal directions is determined and the determination result is outputted (Step 124).
