Method and system for pattern-based intelligent ranging and connectivity feedback to wireless systems

A method for operating a digital key configured to wirelessly connect to a vehicle, comprising:

• receiving wireless communication signal data, wherein the wireless communication signal data includes information about a plurality of wireless communication signals within a predetermined distance from the vehicle, and the wireless communication signal data includes a received signal strength indicator (RSSI) and Channel State Information (CSI) and Channel Quality Information (CQI) of each of the plurality of wireless communication signals within the predetermined distance from the vehicle forming a network pattern;
• receiving vehicle data, wherein the vehicle data includes information about the vehicle, and the vehicle data includes a parking location of the vehicle;
• triggering a digital key system of a vehicle to establish wireless connection with a digital key of a mobile device in response to matching the network pattern and determining that a distance between the mobile device is less than a predetermined distance threshold;
• ranking, using a machine learning model, a plurality of wireless communication technologies for wirelessly connecting the mobile device to the vehicle, wherein the vehicle data and the wireless communication signal data are inputs of the machine learning model;
• selecting one of the plurality of wireless communication technologies based on ranking of the plurality of wireless communication technologies as determined by the machine learning model;
• establishing a wireless communication between the mobile device and the vehicle using the selected one of the plurality of wireless communication technologies, wherein a digital key application is running on the mobile device, thereby allowing the digital key application to operate as the digital key for the vehicle after the wireless communication between the mobile device and the vehicle is established
• receiving navigational data, wherein the navigational data includes a location of the vehicle while the vehicle is moving toward the parking location;
• determining a distance from the location of the vehicle to the parking location using the navigational data;
• comparing the distance from the location of the vehicle to the parking location with the predetermined distance threshold to determine whether the distance from the location of the vehicle to the parking location is less than the predetermined distance threshold;
• and
• collecting the wireless communication signal data in response to determining that the distance from the location of the vehicle to the parking location is less than the predetermined distance threshold, wherein the wireless communication signal data includes the RSSI and Channel State Information (CSI) and Channel Quality Information (CQI) of each of the plurality of wireless communication signals at multiple locations while the vehicle is moving toward the parking location, and the multiple locations are spaced apart from one another by a predetermined distance;
• and
• collecting parking infrastructure data solely in response to determining that the distance from the location of the vehicle to the parking location is less than the predetermined distance threshold, wherein the parking infrastructure data is information about a parking infrastructure in the parking location.
