METHOD AND SYSTEM FOR DETECTING PROXIMITY OF AN END DEVICE TO A VEHICLE BASED ON SIGNAL STRENGTH INFORMATION RECEIVED OVER A BLUETOOTH LOW ENERGY (BLE) ADVERTISING CHANNEL
First Claim
1. A passive entry passive start system, comprising:
- an end device; and
a vehicle, comprising;
a plurality of sensors; and
a central module communicatively coupled to the end device and to the sensors via short-range wireless connections, the central module being configured to;
determine, based on signal strength information measured by and provided from the sensors or the end device, whether the end device is within range for authorization; and
control performance of at least one passive entry passive start (PEPS) function at the vehicle, when the end device is determined to be within range for authorization.

Abstract
A passive entry passive start (PEPS) system is provided for performing at least one PEPS function with respect to a vehicle as an end device (e.g., smart phone or key fob, etc.) approaches the vehicle and comes within range for authorization. The vehicle includes a plurality of sensors and a central module. The central module is communicatively coupled to the end device and to the sensors via short-range wireless connections. The central module can determine, based on signal strength information provided from the sensors or the end device, whether the end device is within range for authorization. When the end device is determined to be within range for authorization, the central module can control performance of at least one PEPS function at the vehicle.

20. A system comprising a vehicle and an end device, the vehicle comprising:
-
a plurality of tires each having a sensor mounted therein, each of the sensors comprising a Bluetooth chipset and a Bluetooth antenna; and a central module comprising another Bluetooth chipset and another Bluetooth antenna, the central module being communicatively coupled to the end device and to the sensors via Bluetooth wireless connections, the central module being configured to; determine, based on signal strength information provided from the sensors or the end device, a distance of the end device from the vehicle and whether the end device is within range for authorization based on the distance of the end device from the vehicle; and control performance of at least one passive entry passive start (PEPS) function at the vehicle when the end device is determined to be within range for authorization.
