Patent ID: 8725346

Claim:
A system for vehicle safety enhancement, comprising: a) a sudden slowdown detection subsystem; b) a slight bump detection subsystem; c) an airbag activation and braking malfunction detection subsystem; d) a rollover detection subsystem; e) a controlling unit connected to each said subsystem for determining a severity level of a collision involving a vehicle based on data received from each said subsystem; and f) a communication unit connected to the controlling unit for transmitting an alert signal based on said severity level of said collision; wherein said sudden slowdown detection subsystem comprises a first accelerometer detecting a predetermined direction with a first dynamic range, and said slight bump detection subsystem comprises a second accelerometer detecting said predetermined direction with a second dynamic range; wherein said second dynamic range is larger than said first dynamic range; wherein said first dynamic range is 6 g and said second dynamic range is between 12 g and 500 g.
