App. No. 11/948,480

Abstract

Claims (46)

1 . A method for selective vehicle accessory component control, comprising the steps of:

receiving a voice command to disable one or more features on a vehicle accessory component while leaving the vehicle ignition active, wherein the voice command is received at a speech recognition engine of a vehicle telematics unit;

verifying that the received voice command is a valid voice command; and

disabling the one or more features on the vehicle accessory component in response to the verified voice command such that the one or more features cannot be activated until an enable command is received at the vehicle accessory component.

2 . The method of claim 1 , further comprising the step of verifying authorization of a user at the speech recognition engine.

3 . The method of claim 2 , wherein the verifying step further comprises the steps of:

sending a prompt for a voice password;

receiving the voice password at the speech recognition engine;

comparing the received voice password to a password stored at the in-vehicle telematics unit; and

verifying the voice password is valid based on the comparison of the received voice password and the stored password.

4 . The method of claim 1 , further comprising the step of processing the received voice command into a vehicle accessory component control command, and the disabling step further comprises executing the control command.

5 . The method of claim 4 , further comprising the step of routing the control command to a control entity for the vehicle accessory component, wherein the control command is executed by the control entity.

6 . The method of claim 1 , further comprising the step of providing a confirmation message that the one or more features have been disabled.

7 . The method of claim 1 , further comprising the step of receiving a voice command to disable one or more features on a vehicle accessory component after a specified delay, wherein the disabling step is performed after the specified delay.

8 . The method of claim 1 , wherein the voice command is interpreted according to a context-free grammar.

9 . A method for selective vehicle accessory component control, comprising the steps of:

receiving a voice command at a speech recognition engine of a vehicle telematics unit to enable one or more features on a vehicle accessory component;

verifying that the received command is a valid voice command and verifying that the one or more features of the vehicle accessory component are currently disabled, and, if so,

enabling the one or more features on the vehicle accessory component.

10 . The method of claim 9 , further comprising the step of verifying authorization of a user at the speech recognition engine.

11 . The method of claim 10 , wherein the verifying step further comprises the steps of:

sending a prompt for a voice password;

receiving the voice password at the speech recognition engine;

comparing the received voice password to a password stored at the in-vehicle telematics unit; and

verifying the voice password is valid based on the comparison of the received voice password and the stored password.

12 . The method of claim 9 , further comprising the step of processing the received voice command into a vehicle accessory component control command, and the enabling step further comprises executing the control command.

13 . The method of claim 12 , further comprising the step of routing the control command to a control entity for the vehicle accessory component, wherein the control command is executed by the control entity.

14 . The method of claim 9 , further comprising the step of providing a confirmation message that the one or more features have been enabled.

15 . The method of claim 9 , wherein the voice command is interpreted according to a context-free grammar.

16 . A method for selective vehicle accessory component control, comprising the steps of:

receiving a voice command to disable at least one feature on a vehicle accessory component while leaving the vehicle ignition active, wherein the voice command is received at a speech recognition engine of a vehicle telematics unit;

verifying that the voice command was received from an authorized user;

processing the received voice command into a vehicle accessory control command;

routing the vehicle accessory control command to a control entity for the vehicle accessory component based upon a selection table comparison; and

disabling the at least one feature on the vehicle accessory component by executing the vehicle accessory control command, wherein the at least one feature cannot be activated until an enable command is received at the vehicle accessory component.

17 . The method of claim 16 , wherein the verifying step further comprises the steps of:

sending a prompt for a voice password;

receiving the voice password at the speech recognition engine;

comparing the received voice password to a password stored at the in-vehicle telematics unit; and

verifying the voice password is valid based on the comparison of the received voice password and the stored password.

18 . The method of claim 16 , wherein the routing step further comprises the steps of:

comparing the vehicle accessory control command to a selection table entry in the vehicle telematics unit;

determining the corresponding control entity for the vehicle accessory component based on the comparison; and

routing the vehicle accessory control command to the corresponding control entity.

19 . The method of claim 16 , further comprising the step of maintain a log of voice commands received by the speech recognition engine to control vehicle accessory components.

20 . The method of claim 16 , further comprising alerting a vehicle owner of an unauthorized attempt to control a disabled vehicle accessory component.
