Abstract

A radio signal jamming device for preventing mobile phone use by a driver when a vehicle is in operation includes a radio signal jammer capable of interfering with the normal operation of a mobile communication device, a controller, and a vehicular interface. The radio signal jamming device is activated when the vehicle is moving and thus preventing the mobile phone carried by the driver from sending and receiving mobile phone calls or text messages.

Claims

1. A radio signal jamming device for a motor vehicle, comprising:

a radio signal transmitter capable of transmitting radio signals of selected frequencies;

a speedometer interface unit for receiving a current speed of the motor vehicle; and

a controller for receiving the current speed from the speedometer interface unit and activating the radio signal transmitter based on the current speed.

2. The radio signal jamming device of claim 1, wherein the controller activates the radio signal transmitter when the current speed is above a select speed.

3. The radio signal jamming device of claim 1, further comprising an onboard diagnostic (OBD) connector interface, wherein the speedometer interface unit obtains the current speed through the OBD connector interface.

4. A method, for operating a radio signal jamming device for a motor vehicle, comprising the steps of:

reading a current speed of the motor vehicle;

determining, by a controller, if the current speed is greater than a select speed; and

if the current speed is greater than the select speed, activating a radio signal transmitter, by the controller; and

transmitting, by the radio signal transmitter, radio signals

5. The method of claim 4, further comprising the step of deactivating the radio signal transmitter, by the controller, if the current speed is below than the select speed.

6. The method of claim 4, further comprising the step of adjusting the select speed while the motor vehicle is stopped.

7. The method of claim 5, further comprising the step of adjusting a radio frequency for the radio signals while the motor vehicle is stopped.

8. A method, for operating a radio signal jamming device for a motor vehicle, comprising the steps of:

receiving, through an external interface unit, environment information;

comparing the environment information with a set of predefined conditions;

if the environment information match the set of predefined conditions, turning on a radio signal jammer; and

emitting, by the radio signal jammer, radio signals.

9. The method of claim 8, further comprising the step of receiving the set of predefined conditions through the external interface, wherein the set of predefined conditions being defined by a user.

10. The method of claim 8, wherein the environment information comprises outside temperature.

11. The method of claim 8, wherein the environment information comprises global positioning system (GPS) coordinates.

12. The method of claim 8, wherein the set of predefined conditions comprises school zone information.
