NXP Trimension UWB powers BMW Group’s digital key plus and presence detectionNXP Semiconductors N.V. has announced that its Trimension NCJ29D6 family will be deployed in the BMW Group's fleet, starting with selected 2026 vehicle programmes.NXP says the Trimension NCJ29D6 is the first monolithic automotive UWB solution to combine 'secure fine-ranging and robust short-range radar capabilities, enabling important safety applications such as presence detection'.The company says 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.AdvertisementAdvertisementBeyond a potential safety enhancement, UWB connectivity offers seamless convenience, according to NXP.BMW's UWB-based Digital Key Plus replaces the traditional key fob with a smartphone or a smart watch. This, NXP says, allows drivers to securely unlock and lock the vehicle automatically and hands-free, even triggering personalised 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 also helps reduce the risk of vulnerable passengers being left behind in a vehicle, where temperature levels can be unsafe.NXP's Trimension NCJ29D6 utilises 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.AdvertisementAdvertisementMarkus Staeblein, Senior Vice President and General Manager, Secure Car Access, NXP Semiconductors, said: "NXP's proven Trimension UWB platform maximizes value for OEMs, using a single system to deliver multiple new and differentiating features for drivers. 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.""NXP Trimension UWB powers BMW Group's digital key plus and presence detection" was originally created and published by Just Auto, a GlobalData owned brand.
