昇润科技PEPS蓝牙解决方案，助推汽车电子“新四化”发展

At the beginning of 2020, the National Development and Reform Commission and 11 other ministries jointly issued the "Intelligent Vehicle Innovation and Development Strategy", proposing: "Looking forward to 2035 to 2050, China's standard intelligent vehicle system will be fully built and more perfect. The vision of a safe, efficient, green and civilized intelligent vehicle power will be gradually realized, and intelligent vehicles will fully meet the people's growing needs for a better life." It has pointed out the direction for the future development of the intelligent vehicle industry.

As an innovative technology under the transformation of automobile intelligence, the keyless entry system has become the focus of major automobile companies. Imagine this scenario: in daily transportation, the owner only needs to approach the vehicle, open the door and enter the car, start the car and go to the destination, and after arriving, just take your belongings and get out of the car. This whole process is smart, convenient, comfortable, and gives people a high-end and upscale feeling.

The so-called keyless entry refers to an intelligent system that uses RFID wireless radio frequency technology and vehicle identity recognition. Specifically, it matches the mobile phone and the vehicle through Bluetooth. The vehicle will sense it within a certain distance and automatically unlock the door; and when the mobile phone leaves the vehicle at a certain distance, the vehicle will automatically lock and enter the anti-theft alert state. In layman's terms, we do not need to use traditional keys or remote controls to open the vehicle's door. The owner only needs to bring the mobile phone into the sensing area to unlock the vehicle.

Over the years, Bluetooth technology has served as a link between cars and drivers, improving safety while continuously enriching the driving experience. Today, Bluetooth technology has once again changed the relationship between cars and car owners, becoming a new technology and new standard for keyless entry.

Bluetooth has been successful in the automotive industry thanks to its ability to enable two solutions: one is audio transmission, and the other is data transmission. Bluetooth is also a standard feature of smartphones, and is highly universal. It can be used on smartphones of all brands, and is very convenient. Therefore, using smartphones as key cards has become an increasingly popular trend for keyless entry of cars. At the same time, Bluetooth technology has a unified communication standard, a huge ecosystem, and obvious cost-effectiveness, making it a widely recognized keyless entry solution.

昇润科技PEPS蓝牙解决方案，采用的是TI CC2640R2F作为主控制器的低功耗蓝牙通信模块（HY-40Q101C），与智能手机和汽车进行无线通信，具有智能化、集成化程度高、使用方便等优点。

(HY-40Q101CC: automotive-grade Bluetooth serial port module)

HY-40Q101C is a Bluetooth low-power single-mode module that meets the AEC-Q100 automotive specification level 2 temperature range (-40℃~+105℃). It is a Bluetooth device for low-power sensors and message transmission; it has the required space for radio, Bluetooth protocol stack, profiles and customer applications, and provides a flexible hardware interface for connecting sensors. HY-40Q101C can be powered directly using a standard 3V button battery or a pair of AAA batteries. In the lowest power shutdown mode, it consumes only 0.15uA and wakes up in a few microseconds.

At the same time, the Bluetooth antenna solution based on TI's automotive-grade Bluetooth chip CC2640R2F, in cooperation with service providers that provide automotive electronic systems to car manufacturers, realizes a new Bluetooth PEPS solution for mobile phone keyless entry and keyless start through cross-technology integration. By deploying multiple Bluetooth antennas around the car, using a mobile phone APP to capture the Bluetooth broadcast signal strength, combined with an algorithm to determine the distance between the phone and the vehicle, it can execute unlocking or locking commands and start the engine and other functions.

昇润科技PEPS蓝牙解决方案优势：

1. Convenient and fast: No need to carry car keys, use widely used mobile phones as interactive work. A mobile phone can control a car;

2. Safe and reliable: Hardware encryption and storage technology ensure communication security. The encryption and decryption of data in the virtual key system is completed by encryption chips, and the keys are stored through encryption chips to ensure the security of data encryption, decryption and storage processes;

3. Lower power consumption: Using BLE low-power Bluetooth technology, the power consumption is lower;

4. Automotive-grade Bluetooth: Bluetooth 5.0 low-power chip solution, automotive-grade testing and mass production experience;

5. Positioning algorithm: Use multiple Bluetooth antennas to accurately locate the phone close to the vehicle;

6. Identity authentication: After the mobile phone and the vehicle complete the identity authentication, the door can be opened, the vehicle can be started, and the vehicle status information can be obtained, which greatly improves the convenience;

7. Provide API: Provide API for mobile APP development.

技术的发展推动了产品的更新，汽车进入系统由原先的机械钥匙变为遥控系统，随着无钥匙进入系统技术的广泛运用和汽车市场的需求，遥控系统被无钥匙进入系统替代已经成为趋势。昇润科技PEPS蓝牙解决方案，符合汽车无钥匙进入的智能发展与创新发展战略，也符合车载电子系统向智能化、网联化、电动化和共享化的汽车的“新四化”方向发展的大趋势。

Bluetooth is more than just keyless entry

The application of Bluetooth technology in the automotive field has a far greater impact than this. According to the "2020 Bluetooth Market Latest Information", it is expected that by 2024, two-thirds of the cars on the road will use Bluetooth technology; at the same time, functions such as infotainment, keyless unlocking, tire pressure monitoring and status alarms have increased the demand for wireless sensors. It is expected that each car will be equipped with 4 to 6 Bluetooth sensors in the future, which also proves that the future application market prospects of Bluetooth technology in the automotive field are very good.
