Abstract

A voice input by a vehicle user is taken as a basis for determining at least one keyword from a set of prescribed keywords. The at least one keyword is taken as a basis for determining at least one event and/or at least one state from a set of events and/or states of the vehicle that are stored during a prescribed period of time. This involves the respective event and/or the respective state being stored in conjunction with at least one condition occurrence that characterizes a respective condition that needs to be met in order for the event to occur and/or the respective state to exist. In addition, a response is determined from a set of prescribed responses on the basis of the condition occurrence that is associated with the determined event and/or state. Furthermore, a signaling signal is determined on the basis of the ascertained response.

Claims

1. A method for operating a voice-controlled information system for a vehicle, the method comprising the acts of:

determining, based on a voice input by a vehicle user, at least one keyword from a set of prescribed keywords;

determining, based on the determined at least one keyword, at least one event and/or at least one state from a set of events and/or states of the vehicle that are stored during a prescribed period of time, wherein the respective event and/or the state is stored in conjunction with at least one condition occurrence characterizing a respective condition that needs to be met in order for the event to occur and/or the state to exist;

determining a response from a set of prescribed responses based on the condition occurrence associated with the determined event and/or determined state; and

determining a signaling signal based on the determined response.

2. The method according to claim 1, wherein

the at least one keyword is taken as a basis for determining a content section of a prescribed interactive instruction manual, and

the signaling signal is determined based on the content section.

3. The method according to claim 2, wherein

the response is determined based on a prescribed characteristic property of the vehicle explicitly identifying the vehicle.

4. The method according to claim 1, wherein

the response is determined based on a prescribed characteristic property of the vehicle explicitly identifying the vehicle.

5. An apparatus for operating a voice-controlled information system, comprising:

a control unit comprising a processor executing a stored program, the stored program having program code segments that;

determine, based on a voice input by a vehicle user, at least one keyword from a set of prescribed keywords;

determine, based on the determined at least one keyword, at least one event and/or at least one state from a set of events and/or states of the vehicle that are stored during a prescribed period of time, wherein the respective event and/or the state is stored in conjunction with at least one condition occurrence characterizing a respective condition that needs to be met in order for the event to occur and/or state to exist;

determine a response from a set of prescribed responses based on the condition occurrence associated with the determined event and/or determined state; and

determine a signaling signal based on the determined response.

6. The apparatus according to claim 5, wherein

the at least one keyword is taken as a basis for determining a content section of a prescribed interactive instruction manual, and

the signaling signal is determined based on the content section.

7. The apparatus according to claim 6, wherein

the response is determined based on a prescribed characteristic property of the vehicle explicitly identifying the vehicle.

8. The apparatus according to claim 5, wherein

the response is determined based on a prescribed characteristic property of the vehicle explicitly identifying the vehicle.
