Abstract: A device is provided for use with a vehicle. The device includes a mode-determining component, a first detecting component and a second detecting component. The mode-determining component can generate an in-vehicle signal. The first detecting component can detect a first parameter and can generate a first detector signal based on the first detected parameter. The second detecting component can detect a second parameter and can generate a second detector signal based on the second detected parameter. The mode-determining component can further generate a crash mode signal based on the in-vehicle signal, the first detector signal and the second detector signal.
