DENSO, announced it has invested in Lambda:4, a German company that develops wireless positioning technologies for short-range applications using Bluetooth Low Energy. The investment will strengthen DENSO’s passive digital key, increasing its location accuracy and user authentication capabilities. This improves safety and security for those using the key on smart devices to enter a vehicle.
Passive digital keys allow approved users to connect their smart devices, such as smart phones, to vehicles without the user ever having to touch a button or open an app. Through the passive digital key, a car can identify when an approved user is approaching; when the approved user is at the car door, unlocking it; and when the approved user is inside, enabling ignition. For this sequence to progress seamlessly, it is critical for the vehicle to be able to quickly identify and authenticate an approved user and pinpoint their location in and around the car.
Lambda:4’s expertise, perfected in producing localization systems for avalanche search and rescue missions, will rapidly increase DENSO’s innovation in localization systems.
The investment is the latest development in DENSO’s work with passive digital keys, which goes back to 2012, when it began developing the technology. Since then, DENSO has become a leader in the space, continually advancing the micro-locating performance of its solution. In 2017, the company acquired InfiniteKey, further expanding the key’s functionality. DENSO’s integrated key is now on the road today.
