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. 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. Digital key and presence detection are just the beginning.
