Program overview
The
keyless entry and start system, referred to as the PEPS system, uses
advanced radio frequency technology to unlock the Automotive door and
enter the vechile 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
Automotive networking process has been accelerating, and more and more
IoT innovation technologies have been used in Vechiles, People are
constantly proposing new conveniences for traveling. The demand not only
realizes the interconnection and mapping between the Vechile 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, Shenzhen Shengrun Technology Co., Ltd. has launched a Bluetooth antenna solution based on TI's Automotive-grade Bluetooth chip CC2640R2F, which cooperates with the automotive manufacturer to provide service for automotive electronic systems. Through cross-technology integration, mobile phone keyless entry and keyless start-up the new Bluetooth PEPS solution. By deploying multiple Bluetooth antennas around the automotive, 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
