Vehicle proximity sensor system for automatic departure/arrival actions
A recently granted patent (Publication Number: US11866004B2) outlines a system designed to enhance vehicle security through the integration of a Vehicle Control System (VCS) and a Radio Frequency (RF) proximity sensor. The RF proximity sensor, equipped with an RF transceiver and a processing module, communicates with authorized user mobile devices and the VCS to estimate distances based on RF transmissions. The system is programmed to detect departure events when authorized user mobile devices move beyond a predetermined distance limit from the vehicle, triggering actions such as activating power locks or security features to enhance vehicle security.
Moreover, the system can also detect arrival events when authorized user mobile devices re-enter the predetermined distance limit, prompting actions like unlocking doors, flashing lights, or deactivating security features. The integration of Bluetooth transceivers in the RF proximity sensor and VCS allows for seamless communication with authorized user mobile devices, enabling precise distance estimation based on Bluetooth transmissions. The system's self-contained RF proximity sensor design, along with the ability to pair with smartphones or smartwatches, offers a versatile and user-friendly approach to vehicle security. The patent also includes a method of operation and an article of manufacture with machine-readable storage devices to implement the system effectively, further enhancing its practical application in the automotive industry.
