Definitions

  • the invention relates to a warning device with a central display of operating states to be monitored in motor vehicles, with a display device which can be controlled by an operation monitoring device.
  • the known warning device includes a central warning lamp that flashes or burns continuously depending on the importance of the critical operating state that occurs, and a group of individual lamps that are each assigned to an operating state that is to be monitored and that also emerge depending on the urgency when such a critical operating state occurs the display flashes or burns continuously.
  • the warning device includes an operational monitoring device in which the information to be displayed is classified according to its urgency or according to the priority of the display and, if necessary, with a desired signal delay for displaying the drop in certain liquid levels, such as erem liquid, cooling water level and windscreen washer water level, cause the display.
  • the operation monitoring device also performs certain functions, for example to measure the engine oil level only when it is at a standstill.
  • the classification is carried out according to the prior art, for example, in such a way that the group of the most important priority includes the oil pressure, the oil level, brake circuit failure and brake fluid, while in a second group information about the brake pad, the hand brake, the cooling water level, the The temperature of the cooling water, the tank reserve, the windscreen washer fluid level, the brake light and the tail light are all arranged.
  • the known warning device includes an acknowledgment button which is connected to the operation monitoring device and which is arranged, for example, in the console of the motor vehicle and with which a warning about a critical operating state that is displayed can be acknowledged.
  • the acknowledge button for example, the blinking of the central warning light is converted into a continuous burning or the continuous burning of the warning light is switched off when a lower priority fault occurs.
  • the individual lights which are assigned to the disrupted operating states to be displayed continue to flash, and the individual lights which are assigned to the disrupted operating states of the lower priority continue to burn, memories which are fed with signals from the operating monitoring device taking effect.
  • the present invention has for its object to avoid the disadvantages of the known warning device with a central display to make the display so that as little additional space as possible in the driver's good field of vision is required on the dashboard console, so that the greatest possible guarantee for the striking one indicated critical operating state is given.
  • This arrangement of the display should be associated with as little additional effort as possible in order to be able to use the warning device desired for safety reasons to the greatest extent possible.
  • the display device is arranged in an analog time clock, the dial of which is translucent in several places with the names of the monitored operating states affixed at these points, which names appear when the lighting of the operation monitoring device can be controlled by the operation monitoring device Lift translucent places from the back of the dial visibly from their surroundings so that the information to be displayed about the operating status can be read from the dial.
  • the surface of the dial of an analog time clock which is normally not used for display purposes, is used to represent the operating states in which the driver is to be warned, without this having to hinder the analog display of the time.
  • the operating states the occurrence of which is to be warned to the driver, can be represented both by a literal description of the operating states and by a symbolic representation using so-called pictograms.
  • the translucent but not transparent surface of the dial which has the corresponding representation of the operating state, can be illuminated from the back of the dial by a light source, for example by a group of light-emitting diodes. When the light source is switched off, the driver is shown in light from the front not visible.
  • the translucent areas on the back of the dial can be illuminated both continuously and intermittently for special emphasis.
  • a variant of the warning device according to the invention has the features that the display device is designed as a display which is arranged in the dial of an analog time clock which can be controlled by the operation monitoring device to display the names of the operating states to be displayed.
  • the space required to display the monitored operating state on the dial is used particularly well, since the individual operating states are not to be displayed at different points, but are made visible at one and the same point by actuating the display.
  • the display can be designed as a dot matrix or can be constructed with liquid crystals.
  • a particularly advantageous variant of the display device according to the invention is characterized in that the display display of a digital time clock is used as the display device, which is coupled to the operation monitoring device and can be controlled by it to display the designation of the operating states to be displayed, such that the operating states to be displayed are of greater importance
  • the time display disappears and the name of the function is shown instead.
  • the display which is present anyway for displaying the time is advantageously used several times in order to also display the operating states to be monitored.
  • the operational monitoring device is switched in such a way that operating states of a high priority level are preferably displayed, the time disappearing during a predetermined period of time or until acknowledgment.
  • the display display has a number of fields equal to the number of priority groups and that the operating states of each field are in one field assigned priority group can be represented.
  • This warning device has the advantage that the operating states of the highest priority are represented in one field and the operating states of the next lower priority are unhindered in a second field by the representation of the critical operating states of higher priority.
  • the least important operating states to be monitored can be displayed in a third field. This arrangement of the fields also improves the clarity of the importance of the disturbed operating state.
  • the display is set up to show the operating state a: .s pictorial representation (pictogram).
  • warning device A further development of the warning device is that a query unit comprising a keyboard is connected to the display and / or the operational monitoring device for selecting the functions to be monitored.
  • functions of lower priority to be monitored can be selected with the keyboard in order to determine successively by operating the keyboard whether the corresponding operating states are present or not.
  • the display can take place either in the display provided for displaying the time or in a separate display field within the clock.
  • the warning device can advantageously have the feature that the display and / or the operational monitoring device is provided with a program memory for coding the name to be displayed in one of several predetermined languages.
  • the part of the stored program that includes the naming of the operating states in the desired language is activated. Switching can be done either by a program switch or by a program card programmed for the respective language.
  • groups of sensors are shown, which are assigned to the engine, the lighting, the chassis and the body.
  • the transmitters provide information about the operating states to be monitored as discrete signals - J-Mein signals - as analog signals, for example depending on resistance transmitters, or as a frequency.
  • Functions of the engine to be monitored are, for example, oil pressure, oil level, oil temperature, cooling water level, cooling water temperature, fuel consumption, engine speed, top dead center and exhaust gas values.
  • Functions of the lighting to be monitored are brake light, tail light, license plate light, parking light, driving light, high beam, fog light.
