Abstract

A dialing mode of a telematics unit in a vehicle is controlled by monitoring for dialing digits from a vehicle occupant, determining whether the type of dialing digits are continuous dialing digits or discrete dialing digits, establishing a continuous mode for receiving continuous dialing digits or a discrete mode for receiving discrete dialing digits based on the determination, and if the type of dialing digits changes, switching the established mode.

Claims

1. A method of controlling an input mode of a telematics unit in a vehicle, comprising the steps of:

(a) prompting a vehicle occupant for a query response;

(b) establishing a temporal window during which the vehicle occupant can respond to the query;

(c) monitoring for both an audible query response received via a microphone and a manual query response received via a tactile device;

(d) detecting the manual query response using the tactile device; and

(e) adjusting the temporal window based on the detection of the manual query response.

2. The method of claim 1, wherein the tactile device is a rotary knob.

3. The method of claim 1, wherein step (d) further comprises displaying menu items and wherein the manual query response is a selection by the vehicle occupant of one of the menu items via the tactile device.

4. The method of claim 1, wherein the tactile device is a keypad.

5. The method of claim 1, wherein detecting the manual query response further comprises detecting physical manipulation of the tactile device by the vehicle occupant.

6. The method of claim 1, wherein adjusting the temporal window further comprises delaying the ending time of the temporal window by adding a predetermined amount of time to the end of the temporal window.

7. The method of claim 6, wherein the predetermined amount of time is stored at the telematics unit.

8. A method of controlling an input mode of a telematics unit in a vehicle, comprising the steps of:

(a) prompting a vehicle occupant for a query response;

(b) establishing a temporal window during which the vehicle occupant can provide the query response via speech inputted into a microphone within the vehicle;

(c) detecting a manual input indicating that at least a part of the query response is being supplied by manual input rather than via the microphone; and

(d) adjusting the temporal window based on the detection of the manual input.

9. The method of claim 8, wherein the step of detecting the manual input further comprises receiving the manual input via a tactile device.

10. The method of claim 9, wherein the tactile device is a rotary knob.

11. The method of claim 9, further comprising displaying a list of menu items for the vehicle occupant and wherein the step of detecting the manual input further comprises detecting user interaction with the list of menu items via the tactile device.

12. The method of claim 9, wherein the tactile device is a keypad.

13. The method of claim 9, wherein the step of detecting the manual input further comprises detecting physical manipulation of the tactile device by the vehicle occupant.

14. The method of claim 8, wherein the step of adjusting the temporal window further comprises delaying the ending time of the temporal window by adding a predetermined amount of time to the end of the temporal window.

15. The method of claim 14, wherein the predetermined amount of time is stored at the telematics unit.
