Abstract

A method and system for controlling use of a communication device in a vehicle is provided. The system includes a plurality of internal vehicle sensors, the vehicle sensors adapted to provide internal information. A receiver is provided adapted to receive external information from an external source and a controller is provided adapted to receive the internal information and the external information. The controller is adapted to assign a risk value to each of the internal and external information and compare the assigned risk values to a predetermined risk threshold and is adapted to disable the communication device when any of the risk values exceeds the predetermined risk threshold.

Claims

1. A method for controlling use of a communication device in a vehicle comprising:

setting the communication device to an enabled state at startup of the vehicle;

monitoring internal risk values calculated from internal information associated with at least one internal vehicle sensor;

monitoring external risk values calculated from external information associated with at least one external information source;

comparing the internal and external risk values to a predetermined risk threshold; and

disabling the communication device when any of the internal and external risk values exceeds the predetermined risk threshold;

wherein the external information includes at least one of weather information, GPS information, safety information, and corridor information; and

wherein the corridor information includes time information.

2. A method for controlling use of a communication device in a vehicle comprising:

setting the communication device to an enabled state at startup of the vehicle;

monitoring internal risk values calculated from internal information associated with at least one internal vehicle sensor;

monitoring external risk values calculated from external information associated with at least one external information source;

comparing the internal and external risk values to a predetermined risk threshold; and

disabling the communication device when any of the internal and external risk values exceeds the predetermined risk threshold;

wherein the external information includes at least one of weather information, GPS information, safety information, and corridor information; and

wherein the corridor information includes location information.

3. A method for controlling use of a communication device in a vehicle comprising:

setting the communication device to an enabled state at startup of the vehicle;

monitoring internal risk values calculated from internal information associated with at least one internal vehicle sensor;

monitoring external risk values calculated from external information associated with at least one external information source;

comparing the internal and external risk values to a predetermined risk threshold; and

disabling the communication device when any of the internal and external risk values exceeds the predetermined risk threshold;

wherein the communication device comprises a device for receiving messages from a caller, and the method further comprises transmitting a “

device busy”

message to the caller when the communication device is in a disabled state.

4. A method for controlling the use of a communication device in a restricted use corridor comprising:

setting the communication device to an enabled state at startup of the vehicle;

monitoring internal risk values calculated from internal information associated with at least one internal vehicle sensor;

monitoring external risk values calculated from external information associated with at least one external information source;

comparing the internal and external risk values to a predetermined risk threshold;

disabling the communication device when any of the internal and external risk values exceeds the predetermined risk threshold;

determining a current location of the vehicle;

determining whether the current location of the vehicle falls within the corridor; and

disabling the communication device when it is determined that the current location of the vehicle falls within the corridor.

5. The method of claim 4 further comprising:

determining a current time of the vehicle;

determining whether the current time of the vehicle falls within a restricted use time period of the corridor; and

disabling the communication device when it is determined that the current location falls within the corridor and the current time falls within the restricted use time period of the corridor.

6. A method for controlling use of a communication device in a vehicle comprising:

setting the communication device to an enabled state at startup of the vehicle;

determining a current time and location of the vehicle;

monitoring internal risk values calculated from internal information associated with at least one internal vehicle sensor;

monitoring external risk values calculated from external information associated with at least one external information source;

transmitting the current time, location, and internal and external risk values to a controller;

performing a corridor query to obtain a corridor risk threshold;

comparing the internal and external risk values to the corridor risk threshold; and

disabling the communication device when any of the internal and external risk values exceeds the corridor risk threshold.

7. The method of claim 6 wherein any combinations of internal risk values is compared to the corridor risk threshold.

8. The method of claim 6 wherein any combinations of external risk values is compared to the corridor risk threshold.

9. The method of claim 6 wherein any combination of internal and external risk values is compared to the corridor risk threshold.

10. A computer readable storage medium which contains program code for controlling use of a communication device in a vehicle, said program code comprising:

computer readable program code to set the communication device to an enabled state at startup of the vehicle;

computer readable program code to determine a current time and location of the vehicle;

computer readable program code to monitor internal risk values calculated from internal information associated with at least one internal vehicle sensor;

computer readable program code to monitor external risk values calculated from external information associated with at least one external information source;

computer readable program code to transmit the current time, location, and internal and external risk values to a controller;

computer readable program code to perform a corridor query to obtain a corridor risk threshold;

computer readable program code to compare the internal and external risk values to the corridor risk threshold; and

computer readable program code to disable the communication device when any of the internal and external risk values exceeds the corridor risk threshold.
