Abstract

In the case of a multi-function operating device for motor vehicles, a single bidirectional rotary switch having stop positions and axial movability is used to designating function groups and to select them by means of an enter function arrangement and subsequently, within the respective function group, select the pertaining function in the same manner. The sole operating element in the form of the rotary switch can be operated without any problems and permits the desired selection or operating function at any time and without drawing attention away from the traffic situation.

Claims

1. An operator control of a multi-function operating device in a motor vehicle for selecting between a plurality of function groups and for selecting individual functions of a selected function group from a menu of the selected function group comprising:

a bidirectional rotary switch for designating one of the plurality of function groups and for designating one of the individual functions of the selected function group from the menu of the selected function group by rotation of said bidirectional rotary switch, said individual functions within a selected function group differing for each of said plurality of function groups;

stop means for providing the rotary switch with a number of stop positions, one of the plurality of function groups and one of the individual functions of each of the function groups being assigned to each of the stop positions; and

enter function means for entering said one designated function group and said one designated individual function of the selected function group, the enter function means being subsequently independently triggered by an axial movement of the rotary switch distinct from said rotation of said bidirectional switch to designate one of the plurality of function groups and one of the individual functions.

2. An operating device according to claim 1, wherein the number of stop positions of the rotary switch is coordinated with at least one of a number of the plurality of function groups and a number of the individual functions of each function group.

3. An operating device according to claim 1, wherein individual displays on a video screen are provided for at least one of each of the plurality of function groups and each of the individual functions of each function group, and wherein the individual display for each of the function groups and each of the individual functions designated by the rotary switch is visually emphasized.

4. An operating device according to claim 3, wherein the individual display for each of the function groups and each of the individual functions designated by the rotary switch is visually emphasized after the triggering of the enter function means.

5. An operating device according to claim 3, wherein the individual display for each of the function groups and each of the individual functions designated by the rotary switch differs before and after the triggering of the enter function means.

6. An operating device according to claim 1, wherein one of the individual functions is an input function for entering a data record, the input function consisting of entering means for successively entering alphanumerical data of the data record via the rotary switch.

7. An operating device according to claim 6, wherein a memory is provided containing a plurality of possible data records, the operating device further comprising selection means for selecting all possible data records corresponding to entered alphanumerical data of an entered data record and for displaying all possible data records corresponding to entered alphanumerical data in a visually differentiated manner.

8. An operating device according to claim 1, further comprising correction means for correcting at least one of an incorrectly entered function group and an incorrectly entered individual function, wherein the correcting means is carried out by the enter function means during a stop position of the rotary switch which is assigned to a correcting function.
