Embodiment Construction

[0017] FIG. 1 shows a tachograph DTCO according to the invention, which is designed in such a way that it has the functionality of the method according to the invention. The tachograph DTCO has a front panel 2 which is provided with an operating element 3 , a display 4 and a plurality of insertion slots 5 into which a data memory 7 designed as a data card 6 can be inserted. The insertion slots 5 completely accommodate the data cards 6 , so that they cannot be accessed from the outside in the tachograph DTCO, in particular during the data transfer. The drive recorder DTCO has a controller 8 for controlling the display on the display 4 . In order to measure the speed of the motor vehicle, the tachograph DTCO is connected to a sensor 9 which transmits to the tachograph DTCO a measurement signal 10 associated with the speed or a rotational speed n of a transmission part, both in analog and digital form. .

[0018] The data card 6 or the data memory 7 belongs to several different...

Abstract

The invention relates to a method for controlling a display (4) of a tachograph (DTCO) which can be connected to data memories (7) that are associated with defined groups. The aim of the invention is to improve this method so as to allow for an ergonomic control of the complex functionality of a digital tachograph while requiring little space. For this purpose, individual groups are associated with defined functional groups or dialogs of the display (4) and the operational controls (3). The tachograph (DTCO) identifies the group the data memory (7) is associated with and then displays a selection of functional groups that can be selected by means of operational controls (3). The display (4) displays only functions and functional groups that are associated with the group of the data memory (7).

Description

technical field [0001] The invention relates to a method for controlling a display of a tachograph, which is connected in a data-transmittable manner to at least one data memory, wherein the data memory is assigned to one of a plurality of groups of a plurality of data memories identified group. Furthermore, the invention relates to a tachograph having: a data memory; a memory for storing recorded operating data; a control unit which controls a display; an operating element, wherein the connectable data memory is controlled by One of multiple groups assigned to multiple datastores. Background technique [0002] The new generation of tachographs or tachographs no longer record the operating data of motor vehicle trips associated with persons on paper chart disks, but in the form of digital storage in accordance with EWG Regulation No. 3821 / 85 on the data storage. Basically, an analog tachograph converts the signal frequency of a tachogenerator located on the transmission o...
