"Mobility as a Service" (MaaS) is changing from a hot concept to an emerging reality, calling for smarter and more convenient mobility solutions. With the 100% popularization of Bluetooth technology in smartphones, "Phone as a Key" (PaaK) is becoming a new trend in Bluetooth location services, bringing keyless entry, start, and exit to car and electric vehicle owners. Lock upgrade experience.

As the world's leading cloud computing and artificial intelligence technology company, Alibaba Cloud is committed to providing safe and reliable computing and data processing capabilities in the form of online public services, making computing and artificial intelligence an inclusive technology. As the leader of the "unlock without feeling, lock when you leave the car" enabled by Bluetooth, Alibaba Cloud IoT Division and Tmall Two-wheeled Vehicle Division jointly launched the "Flash Man" smart electric car in November 2020 travel solutions.

In November 2020, Alibaba Cloud IoT Business Unit and Tmall Motorcycle Business Unit launched a smart electric vehicle travel solution called "Flash Rider", which enables EV users to start the vehicle without having to carry a physical key when going out. After scanning the code and binding, the user can use the smartphone applet to start/lock the car and other operations. If the true sensorless unlocking function is enabled, the user does not even need to take out the mobile phone, the vehicle can be automatically unlocked when approaching the vehicle, and the vehicle will be automatically locked when moving away from the vehicle. This solution greatly facilitates electric vehicle users, especially for groups such as food delivery riders.
The true senseless unlocking launched by Alibaba Cloud IoT Division uses Bluetooth connection to determine the distance between people and vehicles. To do this, the following major technical challenges must be solved: how to make the mobile phone communicate with the vehicle without human intervention, how to ensure the security of the entire setup process and connection process, and how to ensure the judgment of distance precision.

Ge Wei, senior technical expert of Alibaba Cloud, said: "Bluetooth technology has inherent advantages for the above points. It is widely supported on mobile phones and can ensure the security of the connection protocol to a large extent. At the same time, Bluetooth technology can be obtained by obtaining The distance is preliminarily judged by the signal strength of the remote device, and then the accuracy of the distance calculation is improved through the Alibaba Cloud IoT algorithm, so as to provide users with a convenient experience of approaching unlocking and leaving the car locked.”

At present, the Bluetooth SIG (Bluetooth SIG) is preparing to launch a new high-precision distance measurement standard, and the distance measurement accuracy will be improved to about 0.5 meters in the future. If it is applied to the smart electric vehicle solution, the positioning of the person by the vehicle can be more precise. At that time, the overall experience of the user's smart electric vehicle sensorless unlocking will be smoother and more accurate, and the safety will be greatly improved. As a unified standard in the world, Bluetooth technology has extensive support for various products, especially in smart phones. At the same time, the Bluetooth SIG has done a particularly good job in product compatibility, so that the use of Bluetooth technology as the underlying technology of digital keys has a natural advantage.

Alibaba Cloud IoT Division chose the Bluetooth solution to realize the true senseless unlocking function. It is to see that Bluetooth technology has unparalleled convenience as a standard mobile phone. It is believed that in the future, backed by the development of the entire Bluetooth ecosystem, we will see more digital key solutions using Bluetooth technology appear in the field of electric vehicles.

At present, Alibaba Cloud's smart travel solutions have been adopted by many well-known electric vehicle manufacturers such as Emma, Luyuan, and Xindazhou. According to their feedback, the user experience of this solution is at the leading level in the market, and the "true senseless unlocking" function launched has been recognized by consumers, and most of the users who purchased it said that this function is very convenient.

Alibaba Cloud IoT Business Unit will continue to develop in the field of smart travel. In addition to the "true senseless unlocking" function that has been launched, we will also launch more intelligent functions such as "distributed wireless bus" and "thousand-mile sound transmission", which will help the electric vehicle industry. And users continue to bring more intelligent and user-friendly gains.

The smart electric vehicle solution with Bluetooth technology as the underlying communication protocol can not only realize the interaction between the various devices of the electric vehicle, such as the linkage between the vehicle status and the smart helmet, and the information synchronization between the sensors of the body, etc., but also can optimize the human and vehicle Collaboration, vehicle-road collaboration. In the process of intelligent electric vehicles, Bluetooth technology will become the same standard as smartphones in smart electric vehicles due to its good compatibility and technological leadership, as well as a very mature and complete industrial ecology.
