Definitions

  • the present invention relates to a control device with at least one button, e.g. so-called multifunction steering wheels, for use in road vehicles, airplanes or other steered devices.
  • Multifunction steering wheels have been increasingly used in the automotive industry in recent years, for example.
  • the steering wheels have one or more buttons on the impact pot or on the steering wheel rim, e.g. Key switch on, by means of which facilities such as the car radio or the car phone can be conveniently controlled without the driver having to take his hands off the steering wheel. Since the increased use of sequentially shiftable transmissions, the buttons on the steering wheel have also been used frequently to initiate the shifting processes.
  • Steering wheel lock change their position with respect to the driver. Consequently, the driver has to press the button to be actuated, depending on the angular position of the control device, at a different location than when driving straight ahead, when cornering.
  • the button must therefore be preceded by a locating step during which the driver locates the current position of the button to be actuated. The resulting loss of time until the button is pressed, however, can be extremely problematic, especially in critical driving situations.
  • the object of the present invention is therefore to propose a control device with at least one button which avoids the disadvantage mentioned above.
  • a control device with at least one button, the control device having a button unit which extends over a certain area of the control device, at least one area of the button unit being controlled as a button.
  • the actuation of an area of the button unit means that an area of a physical button is logically assigned a switching or operating function.
  • the size and position of the button to be activated can be varied over a wide range. For example, depending on an angular position of the control device, that area of the button unit that is in a desired position with respect to a driver can be controlled as a button.
  • the control device is preferably assigned a device for determining a steering angle of the control device and a device for activating the area of the button unit that is to be activated depending on the determined steering angle.
  • the device for determining the steering angle is already present in the ESP control in many vehicles. The relevant data can then be obtained from this control.
  • the device for activating the specific area of the button unit comprises, for example, a microprocessor which determines the area to be activated on the basis of the data about the steering lock and then controls or activates it.
  • the individually controllable areas of the button unit each have a discrete button. These discrete buttons, for example push buttons, proximity sensors or film pressure sensors, are then controlled individually, ie depending on the steering wheel position, one of these buttons is interconnected with the control of the function to be operated.
  • the individual control can take place by means of an electronic control, or particularly simply mechanically by means of a sliding contact.
  • the button unit comprises a switching element designed as a linear potentiometer, which extends over the certain area of the control device, a voltage difference being divided over the switching element designed as a linear potentiometer depending on the location of the triggering of the switching element.
  • the switching element designed as a linear potentiometer comprises, for example, a pressure sensor in film construction, the output voltage of the pressure sensor depending on the location of the triggering of the pressure sensor.
  • pressure sensors are known, for example, from the product description "Technotes, Interlink Electronics Europe, Rev. 4/90".
  • such a pressure sensor is preferably designed in a ring shape, so that the active area of the sensor extends essentially over the entire circumferential area of a baffle pot or a steering ring of the control device.
  • a specific voltage range for the output voltage of the pressure sensor is set in the evaluation circuit of the sensor in this embodiment, which corresponds to the area of the linear potentiometer to be activated. Only when the output signal of the pressure sensor lies within the voltage range set in this way is the evaluation circuit concluded that the button is triggered and the corresponding function is activated.
  • the button unit comprises a pressure-sensitive display unit, a so-called touch screen.
  • a such a display unit consists, for example, of a flexible display and an XY touchpad arranged underneath.
  • a button can be shown anywhere on the display.
  • the display is controlled by means of a microprocessor, which calculates the parameters required for correcting the steering wheel rotation from the value for the steering wheel lock of the control device and controls the display accordingly.
  • the button shown on the display can always be shown at the same location with respect to the driver, regardless of the respective position of the control device.
  • the microprocessor simultaneously calculates the output signal of the touchpad to be expected when the XY pad is triggered at the location of the button shown. Only if the actual output signal of the touchpad falls within the range determined in this way is this interpreted by the evaluation circuit as triggering the button and the function assigned to the button activated
  • information that is not correlated with an active button can also be displayed with such a display unit. This applies in particular if the display unit is not designed in a ring shape, but also covers the entire central area of the control device. On such a display it is possible, for example, to output the output of a navigation system which may be present, the alignment of this information also being readjusted in accordance with the steering wheel angle.
  • the area of the button unit that is respectively controlled is preferably highlighted optically. This can be done, for example, by means of a lighting system arranged behind the button unit. Alternatively, a layer of regionally controllable luminescent polymers can be arranged in front of the button unit, which is also controlled by the control of the switching unit. In critical driving situations, the controlled area can also advantageously be temporarily enlarged. This can always happen, for example be the case when the ESP control ' intervenes in the driving action. The temporary enlargement of the effective button can be indicated, for example, by a signal tone.
  • the switching function assigned to the activated button can be changed.
  • the button can be assigned a specific function depending on the driving situation.
