Joint Convergence Technology Launches Bluetooth Antenna PEPS Key Solution Based on Ti CC2640Q1R2F

Keyless entry and start the system referred to as the PEPS system, which uses advanced wireless RF technology to achieve no need to operate the car remote control key to unlock the door into the car and one-click start engine. Under existing technical conditions, PEPS has more intelligent access control and higher anti-theft performance, which has gradually become the mainstream of automotive electronic anti-theft system applications. However, with the country vigorously advocated and developed new energy auto industries, the car process was constantly accelerated. More and more Internet innovation technology has been used in the car, and people will continue to put forward new. Demand, not only achieves the interconnection and mapping of cars and mobile phones, but also uses mobile phone unlocking and startup, and the mobile phone can be completed, plus the electronic trend of driver's license and driving license, and go out to carry the car. Therefore, Shenzhen Constant Technology Co., Ltd. has launched a Bluetooth antenna solution based on Ti car grade Bluetooth chip CC2640R2F, and cooperates to provide automotive electronic system supporting service providers. Through cross-technical integration, the keyless entry and key startup New Bluetooth PEPS solution. By deploying a plurality of Bluetooth antennas in the car, the Bluetooth broadcast signal strength, the binding algorithm is used to determine the position of the mobile phone distance, thus performing unlocking or lock instructions, and activation engines. Scene application map Exhibition board photo Solution block diagram Core technology advantage 1. Car grade Bluetooth 4.2 low-power chip solution, more transmission distance 2. Higher security and more stable 3. Combined with the positioning algorithm, use multiple Bluetooth antennas to realize the precision positioning of the mobile phone near the vehicle 4. Only the mobile phone is required to complete the two-way authentication, you can achieve keyless and keyless start functions, but also directly acquire the vehicle status information and diagnostic information directly, greatly enhance convenience 5. Provide API developed by mobile phone app 6. The program currently has been loaded and reached the quantitative standard.
