Abstract

An apparatus and method diverts navigation guidance provided by a phone when an incoming call occurs to achieve uninterrupted route guidance. In one aspect, a communication system is integrated with the phone to divert the route guidance to a vehicle audio system or display screen when there is an incoming call. The communication system can also be integrated with a cradle, a haptic commander or a radio head unit, which can be communicatively connected with the phone and the vehicle, such that when the incoming call occurs, the route guidance information is transmitted from the phone to the vehicle audio system or display screen through the cradle, etc. Furthermore, the communication system can continuously track the vehicle location to restart the navigation system in the phone when the call is ended.

Claims

1. A communication system for providing uninterrupted route guidance to a phone user in a vehicle comprising:

a phone having a navigation system

a memory device for storing at least a portion of route guidance information provided by the navigation system of the phone;

a communication unit communicatively coupled to the memory device;

wherein when an incoming call occurs, the communication unit receives instructions from the phone to transmit the route guidance information stored in the memory device to a vehicle audio system or display screen.

2. The communication system of claim 1, further comprising a vehicle location detecting unit that continuously tracks the vehicle position after the incoming call occurs, such that when the call is ended, the navigation system is resumed to provide the user a latest vehicle location and necessary route guidance.

3. The communication system of claim 1, wherein the communication system is integrated in the phone.

4. The communication system of claim 1, further comprising a cradle for mounting the phone thereon, and wherein the communication system is integrated in a the cradle, and when the incoming call occurs, the communication system in said cradle is triggered to divert the route guidance information from the phone to the vehicle audio system or the display screen.

5. The communication system of claim 1, further comprising a haptic commander, and wherein the communication system is integrated in the haptic commander which is communicatively connected with the phone, and when the incoming call occurs, the communication system in said haptic commander is triggered to divert the route guidance information from the phone to the vehicle audio system or the display screen.

6. The communication system of claim 1, further comprising a radio head unit, and wherein the communication system is integrated in the radio head unit which is communicatively connected with the phone, and when the incoming call occurs, the communication system in said radio head unit is triggered to display the route guidance information thereon, or divert the route guidance information to the vehicle audio system.

7. The communication system of claim 1, wherein the communication system is connected directly or wirelessly to the vehicle audio system or display screen.

8. A method for providing uninterrupted route guidance to a phone user in a vehicle comprising the steps of:

conducting a route guidance operation on the phone;

detecting whether there is an incoming phone call;

storing at least a portion of route guidance information in a memory device;

diverting the stored route guidance information to an audio system or a display screen in the vehicle when an incoming call occurs; and

providing the route guidance information to the user from either the audio system or the display screen in the vehicle until the call ends.

9. The method of claim 8, wherein the step of diverting the stored route guidance to an audio system or a display screen in the vehicle further comprising the steps of:

connecting a cradle to the vehicle;

docking the phone to the cradle; and

transmitting the portion of the route guidance information from the cradle to the audio system or display screen in the vehicle,

wherein the route guidance information is either wirelessly transmitted from the cradle, or the cradle is directly connected to the audio system or display screen in the vehicle.

10. The method of claim 8, wherein the step of diverting the stored route guidance to an audio system or a display screen in the vehicle further comprising the steps of:

connecting the phone to a haptic commander;

connecting the haptic commander to the vehicle; and

transmitting the portion of the route guidance information from the haptic commander to the audio system or display screen in the vehicle,

wherein the route guidance information is either wirelessly transmitted from the haptic commander, or the haptic commander is directly connected to the audio system or display screen in the vehicle.

11. The method of claim 8, further comprising a step of continuously tracking the location of the vehicle and resuming the route guidance operation to provide a latest vehicle location when the call is ended.

12. The method of claim 11, wherein the step of continuously tracking the location of the vehicle further comprising a step of refreshing the route guidance operation according to the vehicle'"'"'s current position.

13. The method of claim 8, wherein the step of storing the portion of the route guidance information when there is an incoming call comprising a step of updating the portion of the route guidance information in the memory device after completing each maneuver in the route guidance.

14. The method of claim 8, wherein the step of diverting the stored route guidance information to an audio system or a display screen in the vehicle further comprising the steps of:

connecting the phone to a radio head unit; and

transmitting the route guidance information from the phone to the radio head unit in the vehicle,

wherein the route guidance information is either wirelessly transmitted from the phone, or the phone is directly connected to the audio system or display screen in the vehicle.

15. A phone device for providing uninterrupted route guidance to a user in a vehicle comprising:

a memory device;

a transceiver including an antenna;

a call control unit; and

a navigation system for conducting a route guidance operation,

wherein the memory device stores at least a portion of route guidance information provided by the navigation system, and when the transceiver receives an incoming phone call, the call control unit diverts the route guidance information stored in the memory device to a vehicle audio system or display screen.

16. The phone device of claim 15, wherein the navigation system continuously tracks the vehicle position after the incoming call occurs and resumes the route guidance operation to provide a latest vehicle location when the call is ended.

17. The phone device of claim 15, wherein the call control unit further comprising a wireless communication unit to wirelessly transmit the route guidance information to the vehicle audio system or display screen.

18. The phone device of claim 15, wherein the call control unit is configured to provide a waiting notice to a caller of the phone device until a route guidance prompt is complete.

19. The phone device of claim 17, wherein the call control unit wirelessly transmits the route guidance information stored in the memory device to either a cradle or a haptic commander via the wireless communication unit, then to the vehicle audio system or display screen.

20. The phone device of claim 17, wherein the call control unit wirelessly transmits the route guidance information stored in the memory device to a radio head unit via the wireless communication unit to display said route guidance.
