Summary:

As automotive consumers’ demand for convenience continues to expand, Car Access systems grow more advanced. From mechanical keys, to passive key fobs, and now phones; Car Access systems today rely on localization to enable Passive Entry Passive Start (PEPS) functionalities. For over two decades these systems were designed with the combination of low frequency (LF) and ultra-high frequency (UHF) transceivers, but with new requirements to secure against common relay attacks as well as consumer’s desire to leverage phone as a key there is a need for further transformation. Due to its ubiquitous nature and well established interoperability testing, Bluetooth Low Energy is a highly desired technology for Passive Entry Passive Start Systems.

Today’s automotive manufactures face two main challenges designing their Passive Entry Passive Start systems. The first challenge is how to improve accuracy for the best possible user experience, and the second challenge is how to secure against attackers manipulating RF signals (i.e. relay attacks) to gain unauthorized access to the vehicle. TI’s SimpleLink SDK supports Bluetooth 5.1 Angle of Arrival and TI’s proprietary Round Trip Time of Flight. With the Real Time Localization System Toolbox provided in the SimpleLink SDK, customers can extract data that can be utilized for developing localization algorithms and securing against attacks on car access systems.

This webinar will detail the theory, benefits and demonstrate the raw capabilities of Bluetooth 5.1 Angle of Arrival and TI Round Trip Time of Flight.
