Vehicle head unit alerts when living being detected in parked vehicle
A recently granted patent (Publication Number: US12005916B2) outlines a method implemented through a head unit in a vehicle to monitor for the presence of a living being left alone in the vehicle's cabin. The method involves the head unit transitioning into a monitoring mode, using microphones to detect out-of-domain sounds, classifying these sounds as indicative of a living being, and alerting the vehicle's last known operator. The system is designed to differentiate between in-domain and out-of-domain sounds, activating alerts and rescue signals if necessary.
Furthermore, the patent details additional features such as activating external lights and the vehicle's horn to attract attention, comparing detected sounds with distress call exemplars, and utilizing stored acoustic signatures for classification. The method also includes a provision for escalating alerts to a second person in case of no response from the first person, as well as retrieving identifying information to aid rescuers. The system aims to ensure the safety and well-being of any living beings inadvertently left in the vehicle, utilizing advanced monitoring techniques and communication protocols to alert relevant parties promptly.
