  • Methods and systems for providing Bluetooth-based passive entry and passive start (PEPS) for a vehicle
    Patent number: 11214232
    Abstract: Systems and methods for performing a vehicle operation. One system includes a plurality of transceivers associated with a vehicle and a vehicle access system. The vehicle access system is configured to receive, via each of the plurality of transceivers, signal strength data associated with a portable communication device using a Bluetooth signal received at an antenna associated with each of the plurality of transceivers, and compare, for each of the plurality of transceivers, the signal strength data with a threshold signal strength value to perform a localization of the portable communication device generating the Bluetooth signal to determine whether the portable communication device is located inside or outside the vehicle. The vehicle access system is also configured to perform the operation based on whether the portable communication device is located inside or outside the vehicle.

  • Secured communication in passive entry passive start (PEPS) systems
    Patent number: 10943416
    Abstract: Systems and methods for secure communication between a vehicle and a portable communication device. One system includes a vehicle access system included in the vehicle. The vehicle access system is configured to wirelessly receive a shuffled message from the portable communication device, de-shuffle the shuffled message at a bit level to obtain a message, wherein de-shuffling the shuffled message at a bit level includes exchanging one bit at a first indexed position within the shuffled message with one bit at a second indexed position within the shuffled message, and initiate a vehicle operation based on the message.
