Electric display device of a vehicle
First Claim
1. An electric display device suitable for a plurality of vehicles, particularly motor vehicles having one or more differing characteristics of construction including number of cylinders and final drive gear ratios, said display device comprising:
- at least one indicating instrument;
a memory which stores at least one desired display value of said construction characteristics;
means for setting said indicating instrument to said display value of said memory in a testing mode, said setting means including switch means for the switchable division of a rate of pulses of a variable to be indicated, particularly a speed of rotation, and whereinsaid memory stores, for display of a preset division of pulse rate, at least two desired display values; and
whereina display in each case of the of the stored desired display values on said indicating instrument is switchable by means of said switch means.

Abstract
An electric display device for a vehicle, particularly a motor vehicle, has at least one display instrument, at least one memory which stores a desired display value and can be set with the display instrument in a test phase, as well as switch means for the switchable dividing of pulses of a variable to be displayed, in particular a speed of rotation. In order to be able, during the test phase, to check a division which has been set, the memory stores at least two desired display values. The output of each of the stored desired display values to the display instrument is switchable by the switch, which also effects the switching of the division. In this way, during the test phase, only the desired display value which corresponds to the setting of the switchable division of pulses is shown.

3. In an electric display device for a vehicle, particularly a motor vehicle, with at least one indicating instrument, with a memory which stores at least one desired display value to which a display means can be set in testing mode, and with switch means for the switchable division of a rate of pulses of a variable to be indicated, particularly a speed of rotation, the improvement wherein
for display of a preset division of pulse rate, the memory stores at least two desired display values; - and wherein a display in each case of one of the stored desired display values on the display means is switchable by means of the switch means, and wherein
the display means, as a combination instrument, comprises digital speed display means, rpm display means and said switch means, said switch means including a coding switch and a programmable divider of rpm impulses operated by said coding switch, and wherein the memory stores a first sequence of digits containing a possible number of cylinders of an engine of the vehicle as a desired display value, a second sequence of digits containing another possible number of cylinders as a desired display value, and a third series of digits activating substantially all segments of the digital speed display means as a desired display number;
said display device further comprising a program control means, and whereinthe memory is connected to the digital speed display means, and by means of the coding switch, a part of the memory which stored the first desired display number or a part of the memory which stores the second desired display number can be deactivated and said program control means activates the first or the second memory part during a first section of a test phase and thereupon a third part of the memory is activated for outputting display data in a second section of the test phase. - View Dependent Claims (4, 5, 6, 7)

8. In an electric display device for a vehicle, particularly a motor vehicle, with at least one indicating instrument, with a memory which stores at least one desired display value to which a display means can be set in testing mode, and with switch means for the switchable division of a rate of pulses of a variable to be indicated, particularly a speed of rotation, the improvement wherein:
-
for display of a preset division of pulse rate, the memory stores at least two desired display values; and
wherein a display in each case of one of the stored desired display values on the display means is switchable by means of the switch means, and whereinwithin the memory there is contained another non-switchable desired display value which can be transmitted alternatively to the display means, the display means, as a combination instrument, comprises digital speed display means, rpm display means and said switch means, said switch means including a coding switch and a programmable divider of rpm impulse operated by said coding switch, and wherein the memory stores a first sequence of digits containing a possible number of cylinders of an engine of the vehicle as a desired display value, a second sequence of digits containing another possible number of cylinders as a desired display value, and a third series of digits activating substantially all segments of the digital speed display means as a desired display number;
said display device further comprising a program control means, and whereinthe memory is connected to the digital speed display means, and by means of the coding switch, a part of the memory which stores the first desired display number or a part of the memory which stores the second desired display number can be deactivated and said program control means activates the first or the second memory part during a first section of the test phase and thereupon a third part of the memory is activated for outputting display data in second section of the test phase.
