Definitions

  • the present invention relates to visual display devices and relates particularly to a device for connection to a processing system which monitors parameters characteristic of the instantaneous operational state of a motor vehicle and parameters characteristic of the variation of this operational state with time and which produces signals indicative of the value of these parameters.
  • the object of the present invention is to provide a visual display device of the type specified above which is particularly simple and efficient to use and allows the driver of a motor vehicle to receive information on the operational state of the motor vehicle itself clearly and rapidly.
  • the present invention provides a visual display device of the type specified above characterised in that it comprises:
  • the visual display device according to the invention is illustrated in one of its possible states within a dashboard P of a motor vehicle (not illustrated).
  • the device includes a visual display unit 2 and a pair of push buttons 3, 4 located adjacent the visual display unit 2 and acting respectively as a selector and a reset switch according to the criteria which will be set out more particularly below,
  • the unit 2 includes three display zones 5, 6, 7 having segment-type digital display elements.
  • Two indicators 5a, 5b having ideographic characters are associated with the visual display zone 5.
  • a similar pair of indicators indicated 6a, 6b and 7a, 7b, respectively are associated with each of the visual display zones 6 and 7.
  • the zones 5, 6, and 7 are vertically aligned with each other.
  • the indicators 5a, 6a, 7a and the indicators 5b, 6b, and 7b have a similar disposition.
  • the visual display device illustrated is intended for connection to a processing system S which monitors parameters characteristic of the operational state of the motor vehicle, and produces with the additional use of further signals which are presented by other instruments (not illustrated) of the dashboard P, signals indicative of the instantaneous value of the fuel consumption, the time, the date, the average fuel consumption, the range' of the vehicle on the basis of the instantaneous consumption and the quantity of fuel present in the tank, the average speed of the motor vehicle and the time which has elapsed from an initial instant input into the processing system itself.
  • the visual display zone 5 is intended for the presentation of signals corresponding to the instantaneous fuel consumption and the average consumption of fuel.
  • the visual display zone 6 is however intended for the presentation of the signals indicative of the range of the motor vehicle and of the average speed of the motor vehicle, while the visual display zone 7 is intended for the display of the time (or the date) and of the time which has elapsed since the initial instant indicated above.
  • auxiliary push buttons 8 are associated with the visual display zone 7 serving as the clock, one of which, indicated 8a, controls the substitution for information relating to the time with that relating to the date while the other two, indicated 8b, are intended to allow the precise adjustment of the time and of the date.
  • the push button 3 is connected to the processing system S and acts on the visual display unit 2 so that when it is in its released condition, signals corresponding to the instantaneous fuel consumption, the range of the motor vehicle and the time (or the date) are presented on the zones 5, 6 and 7.
  • the corresponding ideographic indicators 5a, 6a and 7a are activated.
  • an ideogram for example, a flashing ideogram C, may appear which indicates the selection of a transmission ratio in the gearbox which is not the optimum for minimising the fuel consumption of the vehicle, the indication of the instantaneous fuel consumption possibly being flashed at the same time.
  • the processing system S When the push button 3 is pressed and for several seconds after it has been released, the processing system S outputs a signal which results in the deactivation of the indicators 5a, 6a, 7a and the simultaneous activation of the indicators 5b, 6b and 7t.
  • the presentation of these latter signals may possibly be controlled, as well as by the push button 3, also by a sensor (not illustrated) which detects the condition in which the motor vehicle is stopped with the engine on.
  • the push button 4 is connected to the processing system S to act as a reset switch. Its actuation thus causes the zeroing of the signals (average fuel consumption, average speed, partial time) indicative of the parameters characteristic of the change with time of the fuel consumption, the speed of the motor vehicle, and the time past, and the simultaneous input of a new initial instant into the processing system S. From the instant at which the push button 4 is actuated, the system S starts a new evaluation cycle of the magnitudes (average, partial cumulative value) indicative of the change with time of the operational state of the motor vehicle.
  • the disposition of parts illustrated thus avoids the simultaneous visual display of an excessive number of signals.
  • they are presented in two groups of signals.
  • the two groups are presented as alternatives to each other by operation of the push button 3.
  • the identification of the group of parameters being presented is facilitated by the presence of the indicators 5a, 6a, 7a and 5b, 6b, 7b and the alignment of the indicators corresponding to the members of a single group.
  • the push button 3 or a member equivalent thereto, will also be able to control the presentation rf the signals on the zones 5, 6, 7 and the activation of the corresponding, ideographic indicators (chequered flags).
