UWB got initially utilized in the military field, and began to be commercially applied after the release of criteria for UWB commercialization in 2002. In 2019, Car Connectivity Consortium (CCC) listed UWB as the next-generation vehicle security access technology, conducing to the massive availability to mobile devices. In June 2020, IEEE updated UWB-related standards (802.15.4z), enhanced UWB security functions (at the PHY/RF level), making for wider application of UWB.
In July 2021, CCC officially issued the CCC3.0 standards, which clearly proposes that the combination of UWB and BLE (Bluetooth) wireless technologies enables passive keyless entry and engine start through compatible mobile devices.
CCC Digital Key 3.0 will bring better user experience by implementing UWB connectivity to add hands-free, location-aware keyless entry and location-aware capabilities.
To date, a number of Chinese and foreign OEMs have begun to deploy UWB technology. To ensure the safety of the passive entry system, Range Rover Evoque has started to employ UWB technology since 2018; all NIO ET7 models delivered in early 2022 support the UWB key positioning function (leveraging UWB+Bluetooth+NFC fusion technology), and the upcoming NIO ET5 also plans to carry UWB technology.
In addition, BMW, Hyundai, etc. all plan to launch models outfitted with UWB digital key in 2022, and the UWB digital key will usher in mass production.
Enthusiastically promoted by NIO, Great Wall Motor, Land Rover, BMW and other OEMs, UWB is projected to be available onto millions of passenger cars, accompanied by a sharp fall in the cost of single car. UWB technology will be eventually a standard configuration of intelligent connected vehicles, connecting vehicle to everything.
BMW: In 2021, BMW unveiled the new BMW iDrive system, which is equipped with UWB technology for the first time, and upgraded the mobile car key technology to Digital Key Plus in line with CCC 3.0 communication standards.
BMW Digital Key Plus will be first installed on the BMW iX, which can unlock/lock the doors automatically, but which currently only supports Apple devices with the Apple U1 chip.
In the future, BMW will continue to cooperate with Apple and CCC to develop the digital key 3.0 criterion based on UWB technology, formulating a new technical standard for the global automotive industry.
UWB is still in its infancy in the automotive sector, and it is now used mainly in unconscious entry by UWB digital key. In the future, OEMs hope to open up a smart mobility ecosystem through UWB digital keys, and derive more personalized applications, such as UWB-based automotive AVP, car sharing and car payment.
Besides, UWB-based smart phones are increasingly accessible. In the future, if the mobile phone and automobile UWB technology potential markets are connected through, UWB application-based industry chain ecosystem will become a blue sea market.
It is because UWB can derive a broad industry ecosystem that the companies concerned have begun to actively deploy UWB technology.
KOSTAL: With the mass production and delivery of NIO ET7, KOSTAL's UWB digital key has been truly spawned. KOSTAL has developed an exclusive communication protocol for UWB digital key system, which is compatible with CCC protocol, so that the company's products can suit the wireless communication criteria of different OEMs, which is conducive to popularizing mass production.
In addition, KOSTAL is also proactively developing UWB-based derivative solutions, such as the tailgate kick sensor solution. Through the highly sensitive UWB radar algorithm, the kick action can be accurately detected to realize the automatic opening of the trunk. This technology will be massively available on cars in 2022.
HELLA: In June 2021, Hella rolled out a smart vehicle entry system based on UWB technology. When the car owner is within a distance of 50 meters, the car will automatically detect and identify his/her mobile device; when the owner is within two meters of the car, the car is automatically unlocked; however, the engine can only be started when the smartphone is in the car. The technology will be in mass production within two years, says Hella.
In addition, vehicle access authorization can be digitally managed and shared via HELLA's intelligent vehicle access system, so the technology can also be used in areas such as car sharing services or fleet suppliers.
TsingCar: Relying on R&D accumulation of the parent company TSINGOAL in the UWB field, TsingCar has successfully developed a UWB digital key solution, enabling UWB-based tailgate kick, in-cabin liveness detection, and UWB-based high-precision positioning and navigation AVP function.
