In this way, the display means be controlled very easily. The control means can be arranged in the selector lever itself or in more convenient Way otherwise in the motor vehicle.

Preferably, at least one of the following input variables is supplied to the control means. By means of information about the state of the ignition can be displayed on the display means, whether the ignition is turned on or off. The detection of the state of the door lock (completed, door open, door closed) allows activation or deactivation of the display means when opening or closing the doors. By monitoring the operation of a foot or parking brake, for example, necessary for ignition actuation of a foot brake can be detected. A detection of the state of the drive, so for example engine on or engine off, he continues to allow the display of a possibly necessary operation of the start button. Seat occupancy recognition and monitoring of the belt buckles, for example, a start of the engine can be prevented, as long as not all passengers are belted. Another vehicle-relevant information is the state of a transmission of the vehicle. Hereby, for example, a shutdown of the engine can only be allowed if the transmission in a neutral position or inlaid first gear (manual transmission) or parking position (automatic transmission) allow. In addition, when the vehicle is rolling, it is possible to display an inoperable engagement of a reverse gear.

in the Trap optical display means is the actuator preferably formed transparent at least in sections.

If the bulbs have different colors, can the information to be displayed very clear and directly noticeable. Different luminous colors can be achieved by different colored bulbs Be, bulbs that are capable of one of several colors and illuminants that indicate a wider color gamut, for example, white light, and that by intent of color filters be perceived with a specific color. For example three colors provided, blue, green, red, so can be a blue Show light unlocking the door locks. For example, red can signal a starter lock z. B., because the driver does not keep the foot brake, or because not all inmates are strapped Green can For example, signal a release of the starter, if all Conditions for starting are fulfilled. green and red, for example, can have a Give feedback on switching recommendations, for Example green for a particularly economical Switch point and red for reaching a speed limit of the drive unit.

If Control means and / or bulbs in addition to this are designed to be operated flashing so can by different flashing modes of the optical bulbs more Information will be presented. For example, if the control can fulfill several operating functions, for example ignition on / off as well as start engine / switch off engine, so can with a steady light a switched off ignition can be signaled and through a flashing light turned on the ignition, but turned off Engine.

If the bulbs and the control means beyond are designed to produce different brightnesses, Further information can be visualized.

A Further advantageous embodiment provides that the display means include tactile means. Such tactile means must not exclusively detectable only by the sense of touch but can also be visually perceptible. Also tactile display means are very suitable for displaying information.

A Preferred embodiment of a tactile display means relates an axially adjustable actuator, so one, that between two or more positions substantially in the printing direction of the actuating element is displaceable. When a startup the drive unit is not possible, the actuator for example, be retracted, and when starting possible is because, for example, all the occupants are strapped in and the driver the foot brake is actuated, the actuator extend, for example, about 5 mm.

If such a tactile means is provided in connection with a rotary or rotary pressure-actuatable actuating element, this is according to a development of the invention only in an extended position rotatable and possibly pressure-actuated and in a retracted position possibly druckbetätigbar. Thus, the number of available operating options can be limited to a reasonable choice by a rotary actuator is only allowed if this makes sense, eg. B. after switching on the ignition of the vehicle and when the vehicle is stationary, so as not to distract the operator from the traffic.

A Development of the invention with adjustable actuator provides that the actuating element via a Push rod is extended and retracted. In case that for the actuating element a housing is provided, the entire housing is preferably raised and lowered. In this way, the operating feeling remains as well as the protection against incorrect operation independent of the extended state of the actuating element.

The Push rod is preferably guided in the selector lever, causing a drive for the push rod in areas can arrange, in which more space available stands.

Of the Drive itself is preferably designed as an eccentric drive at a push rod eccentrically on an output shaft of a drive is held. This allows a particularly compact Construction.

Farther is provided with advantage that haptic display means with optical Display means are combined. This allows the display of more Information or a particularly intuitive presentation of information. Thus, an activated ignition by an extended Actuator be signaled, a Nichtbetätigen a foot brake but by a red glow.
