Patent Images
1. A siren detection and notification system comprising:
- a vehicle bus interface;
a memory comprising;
a siren model;
a vehicle environment sound signal; and
a siren processing program operable to;
analyze the vehicle environment sound signal with respect to the siren model to determine whether a siren sound is detected in the vehicle environment sound signal; and
issue a vehicle system control command over the vehicle bus interface when the siren sound is detected in the vehicle environment sound signal; and
a processor coupled to the memory and the vehicle bus interface that executes the siren processing program.

Abstract
A monitoring and notification system detects and informs vehicle occupants of sirens. The system may adjust radio, phone, or other device settings in the vehicle in conjunction with the notification. The notification may take an audible or visual form, and the monitoring system may perform its analysis across multiple types of sirens. In addition, the system may adapt its processing based on location to take into account locally expected siren formats.
