Abstract

Disclosed is a controller to prevent access or utilization by a vehicle operator to communications devices installed on the vehicle when the vehicle is in motion thereby reducing distractions of the operator.

Claims

1. A utilization control system for limiting access by the operator of a vehicle to programmable computer having ports for delivering output signals to communications devices mounted on said vehicle comprising:

at least one vehicle motion condition detector providing signals indicative of current motion of said vehicle and of potential motion of said vehicle;

at least one signal processor responsive to signals provided by said at least one detector indicative of vehicle motion and potential vehicle motion to generate blanking signals;

at least one vehicle mounted communications device; and

at least one blanking device associated with said signal processor and said communications device responsive to said blanking signals and configured to shut down output from the computer ports to said communications device to prevent utilization or interaction with said at least one communications device by said vehicle operator.

2. The system of claim 1 wherein said at least one motion condition detector comprises a transmission park/neutral switch.

3. The system of claim 1 wherein said at least one signal processor comprises a programmable digital signal processor configured to deliver outputs to temporarily block device outputs that may be dangerously distracting to the vehicle operator at that time.

4. The system of claim 3 wherein said programmable digital signal processor is a “

PC”

type computer.

5. The system of claim 4 wherein said “

PC”

computer includes an output monitor and an input keyboard.

6. The system of claim 5 wherein said at least one motion condition detector comprises a transmission park/neutral switch.

7. The system of claim 1 wherein said at least one motion condition detector comprises an accelerometer.

8. The system of claim 1 wherein said at least one motion condition detector comprises an antilock brake system.

9. The system of claim 1 wherein said at least one motion condition detector comprises an electrical speedometer.

10. The system of claim 1 further comprising an optical isolater circuit in the signal path between said at least one vehicle motion condition detector and said at least one signal processor.

11. The system of claim 1, wherein the at least one signal processor is external to the at least one vehicle mounted communications device.

12. A utilization control system for limiting access by the operator of the vehicle to communications devices mounted on said vehicle comprising:

a vehicle motion condition detector providing signals indicative of current motion of said vehicle and of potential motion of said vehicle said detector comprising a transmission park/neutral switch;

a programmable digital computer used as a communication device on board said vehicle; and

an optical isolater circuit in the signal path between said vehicle motion condition detector and said programmable digital computer, said computer being programmed to be responsive to said signals indicative of motion and of potential motion to generate blanking signals applied to said digital computer and limiting said operator'"'"'s utilization of said computer.

13. The system of claim 12 wherein said blanking signals are additionally applied to others of said communication devices mounted on said vehicle.

14. The system of claim 13 wherein said others of said communications devices include voice communications devices.

15. The system of claim 13 wherein said others of said communications devices include visual communications devices.

16. The system of claim 12, wherein the blanking signals inhibit user input to the digital computer.

17. A method, executed by a computer, comprising:

detecting a vehicle motion condition of a vehicle, wherein the vehicle motion condition indicates whether it is possible for the vehicle to be currently in motion; and

in response to die vehicle motion condition indicating that it is possible for the vehicle to be currently in motion, disabling communications through at least one port of the computer with at least one peripheral device associated with the computer so as to prevent interaction of the computer with a user of the computer.

18. The method of claim 17, wherein the vehicle motion condition is detected through a sensor configured to communicate with the computer.

19. The method of claim 18, wherein the sensor senses a status of a transmission park/neutral switch associated with the vehicle.

20. The method of claim 18, further comprising:

determining whether the sensor can currently communicate with the computer; and

in response to a determination that the sensor cannot currently communicate with the computer, disabling the at least one peripheral device.

21. The method of claim 18, wherein the sensor senses actual movement of the vehicle.

22. The method of claim 17, wherein the at least one peripheral device includes a user input device.

23. The method of claim 17 wherein the at least one peripheral device includes an output device.
