NXP Semiconductors said its Trimension NCJ29D6 family will be used in BMW Group vehicles, starting with selected 2026 model programs.
The move is part of what NXP describes as the industry’s broadest UWB portfolio, and the NCJ29D6 is billed as the first monolithic automotive UWB solution to combine secure fine-ranging with short-range radar capabilities for safety uses such as presence detection.
The technology is designed to support drivers with added safety features while keeping the person behind the wheel in full control and responsible at all times.
It also brings convenience for BMW UWB Digital Key Plus as it can now replace a traditional key fob with a smartphone or smart watch, allowing secure, hands-free locking and unlocking, along with personalized welcome features such as lighting and entry sequences.
NXP said the system is also aimed at meeting emerging regulatory expectations and future NCAP protocols in Europe and China. Its presence detection function is intended to reduce the risk of vulnerable passengers being left in a parked vehicle, where temperatures can quickly become unsafe.
Using UWB, the Trimension NCJ29D6 can detect signs of a living being left in the cabin by picking up subtle motion patterns associated with occupant presence. When the system senses that a person or animal may still be inside, it alerts vehicle users with a warning message.
Leadership Comment
“NXP’s proven Trimension UWB platform maximizes value for OEMs, using a single system to deliver multiple new and differentiating features for drivers,” said Markus Staeblein, Senior Vice President and General Manager, Secure Car Access, NXP Semiconductors. “Digital key and presence detection are just the beginning. OEMs will be able to deliver additional UWB-based features, such as kick sensing, intrusion alert or automatic charging, as they establish the secure hardware platform in their vehicles.”
