ABSTRACT:
A device for emitting audible signals within a vehicle compartment for notifying a driver of a vehicle of the presence of objects at predetermined locations around the vehicle. The driver is alerted to the presence of objects at predetermined sensing zones around the vehicle through the presence of audibly distinct tones corresponding to each sensing zone. Thus, an object present in any sensing zone causes a unique, audibly distinct sound to be generated within the cabin for warning the driver of the presence of a particular object.
