Abstract

The car collision global positioning system transmits an emergency alert signal to emergency authorities upon detection of a collision or other vehicular accident. A plurality of collision sensors are mounted in a body of a vehicle for detecting a vehicle collision. Preferably, each collision sensor further measures a velocity of the vehicle at a time of a collision. A collision signal is generated when at least one of the plurality of collision sensors detects the collision and the measured velocity exceeds a pre-set velocity threshold. Additionally, at least one overturn sensor is provided for generating an overturn signal when the vehicle overturns, and a deployment sensor is also provided for generating a deployment signal when an airbag of the vehicle is deployed. When at least one of the collision signal, the overturn signal or the deployment signal are generated, an emergency alert signal is generated and transmitted.

Claims

a plurality of collision sensors adapted for mounting in a body of a vehicle, the plurality of collision sensors including first, second, third and fourth pairs of force-actuated microswitches, the first pair of force-actuated microswitches being adapted for mounting on a front end of the body of the vehicle, the second and third pairs of force-actuated microswitches being adapted for mounting on opposing sides of the body of the vehicle, and the fourth pair of force-actuated microswitches being adapted for mounting on a rear end of the body of the vehicle, each of the first and fourth pairs of force-actuated microswitches including a driver'"'"'s side force-actuated microswitch and a passenger'"'"'s side force-actuated microswitch;

means for generating a collision signal when at least one of the plurality of collision sensors detects that the vehicle has been involved in a collision;

means for generating an overturn signal when the vehicle overturns;

means for generating a deployment signal when an airbag of the vehicle is deployed; and

means for transmitting an alert signal when at least one of the collision signal, the overturn signal and the deployment signal is generated.

2. The automotive accident alert system as recited in claim 1, further comprising means for locating the vehicle, wherein the alert signal includes location data for the vehicle.

3. The automotive accident alert system as recited in claim 2, wherein said means for locating the vehicle comprises a global positioning system receiver connected to said means for transmitting an alert signal.

4. The automotive accident alert system as recited in claim 3, wherein said means for generating the overturn signal comprises a mercury switch.

5. The automotive accident alert system as recited in claim 4, wherein said means for transmitting the alert signal comprises a microwave satellite transmitter.

6. The automotive accident alert system as recited in claim 1, wherein said means for transmitting the alert signal comprises an automatic transmitter configured for automatically transmitting the alert signal when at least one of said collision signal, said overturn signal and said deployment signal is generated.

7. The automotive accident alert system as recited in claim 1, wherein said means for transmitting the alert signal comprises a selectively operated transmitter, the selectively operated transmitter including a control circuit configured for preventing transmission of the alert signal upon receipt of a cancellation request by the driver.

8. The automotive accident alert system as recited in claim 7, further comprising a timer, wherein said selectively operated transmitter automatically transmits the alert signal if the cancellation request is not received from the driver within a pre-set time from generation of at least one of said collision signal, said overturn signal and said deployment signal.

9. The automotive accident alert system as recited in claim 1, wherein the alert signal includes driver identification information.

10. The automotive accident alert system as recited in claim 9, wherein the driver identification information includes a cellular telephone number assigned to the driver of the vehicle.

11. The automotive accident alert system as recited in claim 1, wherein each said collision sensor further comprises a vehicle speed sensing circuit, said collision sensor being configured to suppress the collision signal unless the vehicle speed sensing circuit detects a vehicle speed exceeding a pre-set threshold at the time of the collision.

12. The automotive accident alert system as recited in claim 1, further comprising a global positioning system (GPS) receiver in communication with each said collision sensor, said collision sensor being configured to suppress the collision signal unless the GPS receiver detects a vehicle speed exceeding a pre-set threshold at the time of the collision.

13. The automotive accident alert system as recited in claim 1, wherein each said collision sensor is adapted for communication with an engine control unit of the vehicle, said collision sensor being configured to suppress the collision signal unless the engine control unit detects a vehicle speed exceeding a pre-set threshold at the time of the collision.

14. The automotive accident alert system as recited in claim 1, further comprising a control circuit connected to each said collision sensor and to said means for transmitting an alert signal, said control circuit receiving a vehicle speed signal, said control circuit being configured to suppress the alert signal unless the vehicle speed signal represents a vehicle speed in excess of a pre-set threshold at the time of the collision.
