Abstract
A method of determining a critical vehicle event. The method includes receiving vehicle speed data and airbag status data at a remote server. The method further includes deriving, at the remote server, a vehicle deceleration from the vehicle speed data. The airbag status data is analyzed at the remote server to determine whether an airbag on the vehicle has deployed, wherein the analyzing of the airbag status data occurs when a magnitude of the derived vehicle deceleration is above a preset magnitude. The method additionally comprises generating a critical event confirmation signal when the airbag status data reveals deployment of the airbag on the vehicle.
Claims22
A method of detecting a critical vehicle event based on multiple vehicle operation factors, the method comprising the steps of:
- receiving vehicle speed data associated with operation of a vehicle;
- deriving a vehicle deceleration from the vehicle speed data;
- receiving airbag status data associated with operation of the vehicle;
- comparing the received airbag status data with stored data on a remote server;
- and
- generating a critical event confirmation signal at the remote server when the derived vehicle deceleration is above a preset magnitude and the comparison of the received airbag status data with the stored data reveals that the airbag on the vehicle has deployed.
A system for detecting a critical vehicle event, the system comprising:
- a data acquisition and transfer device disposable in communication with a vehicle computer to receive vehicle speed data and airbag status data from the vehicle computer, the data acquisition and transfer device being operative to derive a vehicle deceleration from the vehicle speed data and generate a hard stop signal when the derived vehicle deceleration is above a preset magnitude;
- and
- a server disposable in communication with the data acquisition and transfer device to receive the airbag status data and the hard stop signal therefrom, the server being operative generate a critical event confirmation signal when the hard stop signal is received and airbag status data reveals deployment of the airbag on the vehicle.
A method of detecting a critical vehicle event of a vehicle, the method comprising the steps of:
- determining a vehicle deceleration at a data acquisition and transfer device;
- receiving airbag status data at the remote server a;
- comparing, at the remote server, the received airbag status data with stored airbag status data on the remote server to determine whether an airbag on the vehicle has deployed;
- and
- generating a critical event confirmation signal at the remote server when the determined vehicle deceleration is above a preset magnitude and the comparison of the received airbag status data with the stored airbag status data reveals that the airbag on the vehicle has deployed.
