Localization And Passive Entry/Passive Start Systems And Methods For Vehicles

Systems and methods for localization and passive entry/passive start (PEPS) systems for vehicles are provided. A communication gateway establishes a wireless communication link with a portable device. Sensors communicate with the communication gateway, receive connection information about the wireless communication link, and measure signal information of communication signals transmitting communication packets sent from the portable device to the communication gateway via the wireless communication link. A localization module determines a location of the portable device based on the signal information from the sensors. A PEPS system receives performs a vehicle function including unlocking a door of the vehicle, unlocking a trunk of the vehicle, or allowing the vehicle to be started based on the location of the portable device. A security module compares first data in the communication packets received by the communication gateway with second data in the communication packets received by the plurality of sensors.
