Solution Overview
The Passive Entry Passive Start, referred to as the PEPS system, uses advanced radio frequency technology to unlock the door and enter the car without the need to operate the car’s remote control key. Under the existing technical conditions, PEPS has more intelligent access control management and higher anti-theft performance, and has gradually become the mainstream of automotive electronic anti-theft system applications. However, with the vigorous promotion and development of the new energy automobile industry in recent years, the car networking process has been accelerating, and more and more IoT innovation technologies have been used in cars. People are constantly proposing new conveniences for travel convenience. The demand not only realizes the interconnection and mapping between the car and the mobile phone, but also the unlocking and starting of the car, and hopes to complete it with the mobile phone. In addition, the driver’s license and the driving license are electronically trended, and the car can be started by simply carrying the mobile phone.

Therefore, our company has launched a Bluetooth antenna solution based on TI’s car-grade Bluetooth chip CC2640R2F, and cooperates with the car manufacturer to provide a service provider for the automotive electronic system. Through the cross-technology integration, the new Bluetooth PEPS solution for mobile phone keyless entry and keyless start-up is realized. . By deploying multiple Bluetooth antennas around the car, the mobile phone APP captures the broadcast signal strength of the Bluetooth, and combines the algorithm to determine the location of the mobile phone from the vehicle, thereby performing functions such as unlocking or locking the car and starting the engine.

1, car-grade Bluetooth 4.2 low-power chip solution, transmission distance is farther
2, higher security, more stable
3, combined with the positioning algorithm, using multiple Bluetooth antennas to achieve accurate positioning of the mobile phone close to the vehicle
4, only need mobile phone and vehicle to complete two-way identity authentication, you can use the mobile phone to unlock the door, start the engine and get vehicle status information, etc., greatly improving convenience
5, provide API for mobile APP development
6, the car-grade module can be quantitative maturely
