Acquisition and display device for travel parameters of a motor vehicle

The invention relates to a device for detection and display of travel parameters in a motor vehicle.

Numerous devices are known for recording and displaying travel parameters of a motor vehicle. Such facilities _. signals are mounted on the dashboard and inform the Drivers about various parameters relating to several functions that appear during a trip, for example those since Departure elapsed time, average speed, real time, date, etc. Further, facilities are known that also provide further information which is not strictly related to the trip depend on themselves, for example a display regarding the outside temperature, the generation of a warning signal at specified times, etc.

At present the devices mentioned are commercially available only as separate components, so that their installation is serious Problems with the dimensions because it is in a Must be mounted in a position that is clearly visible to the driver. It should be noted that none of the previously known devices is really fully satisfactory. Furthermore, such devices are not readily aesthetically pleasing Dashboards identical to their structure can be adjusted,. which, however have different colors.

The object of the present invention is to create a device of the type mentioned at the beginning, which at the same time the functions previously fulfilled, but overall overcomes the disadvantages mentioned of the same.

According to the present invention, this object is achieved by

that the facility for the acquisition and display of. The travel parameters of a motor vehicle include: ''

- a pot-shaped housing in which electronic processing circuits are accommodated, and that in a correspondingly shaped th space of the dashboard of the motor vehicle 'can be accommodated is, as well

a cover which covers the housing and a plurality of openings, each from a solid-state display unit or a plurality of snaps, which extend through the cover and connect to electronic processing circuitry within the housing.

Referring now to the accompanying drawings a preferred embodiment explained in detail. Fig. 1 is a front view of a front panel of a device according to the invention and

FIG. 2 is a partially sectioned side view of FIG Device according to Fig. 1, shown in the assembled state in the dashboard of a motor vehicle.

In Fig. 1 is the entire device for detection 'and display the travel parameter of a motor vehicle is denoted by 1; the device is designed according to the teaching of the present invention.

In detail, the device 1 comprises a pot-shaped housing 2 (see FIG. 2), which can be mounted in a corresponding space 3

which is formed in the dashboard 4 of a motor vehicle. The case 2 houses electronic processing circuitry 5 of known design and is closed by a cover 6, which is deformable by means of springs, tooth-like projections 8 in ■ snap-in connection into a radially outwardly protruding one

ring-shaped circumferential edge 7 of the housing 2 can be snapped into place. The cover 6 is mounted in an inclined position relative to the side walls of the housing 2 in such a way that it follows an outer profile of the dashboard 4, denoted by 9.

According to the invention, the cover 6 has a plurality of Openings 11, the first of which by a solid-state display unit

unit 12 is taken, the four display elements 13 of the seven; Segment-type includes and a cross-shaped display element 14. Longitudinal next of the display unit 12, which is relative to that defined by the cover 6 Level is set back so that the displays are easier to read, two .Druckknobs 15 and 16 are provided, on which the letters "h" or "m" are marked. These push buttons allow when depressed

. Corrections regarding the display of hours (h) and minutes (m), which are displayed by the unit 12 in a predetermined configuration.

Below the unit 12 and substantially along the opposite sides On the sides of the cover 6, two sets of three snap fasteners 17, 18, 19 or. 21, 22, 23 are provided. Longitudinally with everyone the mentioned push buttons is an associated indicator lamp 27, 28, 29 or 31, 32, 33 are provided, together with an associated symbol or word. In addition to the lamps 27, 28, 29, the words or " Symbols "TIME", "DATE" or "E.T." indicated, next to lamps 31, 32, 33 the words or symbols "TIMER", "T ° EST" or "km / h" are indicated » Each word or symbol relates to a predefined function which can be selected by the relevant push button and by the display unit 12 can be displayed.

In the central position of the cover 6 there is another push button 2o on which the word "RESET" is indicated and above it a acoustic transducer 3o. All push buttons, lamps and the acoustic one Transducers ″ which have been explained above are each received in an associated opening 11 of the cover 6.

The functions assigned to the push buttons 27, 28, 29 or 31, 32, 33 are as follows:

- TIME: This calls up the clock function (hours and Minutes. Or vice versa);

'~ 0 ■ - DATE: This calls up the date function (month and day or vice versa);

- E.T. . So that we get the travel time function that is based on based on a count starting with the start of the journey;

- TIMER: This calls up the alarm function according to which the Device 1 generates an acoustic signal via the acoustic transducer 3o at a predetermined point in time;

-K- 6

- T ⁰ EST: This calls up the outside temperature function, by means of which the display unit 12 is caused to display the outside temperature, which is detected by means of a corresponding "sensor mounted on the vehicle, and"

-Km / h: This is the function of the "average speed" · which is calculated taking into account the time that has been since the start of the journey has elapsed and the number of kilometers that have been driven since the start of the trip. . ·

By means of the push button 2o (RESET) it is possible to · the travel time

reset to zero and also the value of the mean cruising speed as explained above.

The push buttons 15 and 16 (h, m) enable the two symbols to increment on the left or right side of the display unit 12, to set the exact specification of the real time or the alarm time » · From the above explanation of the features of the device 1 according to The advantages resulting from its conception result from the present invention. Above all, the dimensions are extremely limited because each function essentially requires a single push button, while the display unit 12 is associated with all functions in common. That's why it is much easier for the driver to select the desired function, and, moreover, the costs associated with installation are drastically reduced since there is only one device on the dashboard of the motor vehicle must be mounted.

Further advantages result from the fact that the display

unit which is partially enclosed within the housing 2, is particularly well protected against external light, so that the displays it delivers appear in good contrast and therefore from the driver. are easy to read. . .

Finally you can see that thanks to the fact that the cover

6 sits in a snap connection on the housing 2 and not mechanically fastened elements (snaps, lamps, etc.) are arranged on it, which are necessary for the operation of the device 1, the replacement of the cover 6 is extremely easy. This enables the color of the cover 6 so that it matches the color of the

" · .Boards or harmonizes with the colors of the interior of the vehicle.

Finally, it is clear that the device 1 described above can be modified and changed without departing from the basic idea of the present invention.
