NXP Semiconductors N.V. has announced that its Trimension NCJ29D6 ultra-wideband (UWB) solution will be deployed across the BMW Group’s vehicle lineup, beginning with selected 2026 model programs. The latest integration strengthens BMW’s connected vehicle capabilities by supporting advanced features such as Digital Key Plus and in-cabin presence detection.
Part of NXP’s extensive automotive UWB portfolio, the Trimension NCJ29D6 is the industry’s first monolithic automotive UWB solution to combine secure fine-ranging with robust short-range radar capabilities. This enables precise digital access, enhanced vehicle security, and advanced safety applications, including reliable occupant presence detection, further advancing the next generation of intelligent and connected mobility.
Drivers benefit from a combination of enhanced safety features, such as presence detection, which provides continuous support during use. Despite this assistance, the driver retains full control of the vehicle and remains responsible at all times. Beyond a potential safety enhancement, UWB connectivity offers seamless convenience. For instance, BMW’s UWB-based Digital Key Plus replaces the traditional key fob with a smartphone or a smart watch. This allows drivers to securely unlock and lock the vehicle automatically and hands-free, even triggering personalized experiences like individual light conditions and welcome sequence upon approach.
Addressing potentially emerging regulatory requirements and supporting future NCAP protocols in Europe and China, presence detection technology helps reduce the risk of vulnerable passengers being left behind in a vehicle, where temperature levels can be unsafe. NXP’s Trimension NCJ29D6 utilizes UWB technology to detect a living being left behind in the car by identifying subtle motion patterns consistent with occupant presence. The in-cabin presence detection system indicates the possible presence of people or animals in the cabin when parked and sends a warning message to vehicle users.
“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.”
