A localized accident notification system includes an accident detector
that detects a crash of a vehicle and an external alert system to provide
an external alert by the vehicle that can be noticed by any people in the
vicinity of the crash. Upon an indication of a crash from the accident
detector a controller can direct the external alert. The external alert
can have special notification properties. The accident detector may only
operate if the vehicle ignition is on to discriminate between a theft
alarm. The accident detector can include accelerometers, air bag
detectors, or tilt sensors.
