UWB radar technology enables precise Child Presence Detection (CPD) by recognizing vital signs such as breathing or heartbeat – a crucial function for preventing accidents caused by unnoticed occupants in vehicles.
The radar can detect life signs even through materials like clothing or blankets, ensuring reliable identification of living beings, even when they are covered or motionless. These capabilities form the foundation for intelligent in-cabin safety and monitoring systems.

By utilizing UWB-based in-cabin monitoring even when the vehicle is parked and locked, additional cost and system efficiencies can be achieved. The technology reliably detects unauthorized movements or break-ins, making separate alarm sensors unnecessary. In this “alarm system” mode, the radar operates with a significantly reduced measurement frequency to ensure minimal standby power consumption while maintaining high detection reliability.

Automatic electric vehicle charging relies on precise localization to ensure a seamless connection between the vehicle and the charging system. UWB technology enables this high-accuracy positioning, allowing charging stations or robots to autonomously align with the vehicle’s charging interface—whether connecting through a conventional plug or an inductive charging surface. This precision supports fully automated parking and docking processes, both in public charging zones and private garages, paving the way for convenient, contactless, and efficient EV charging.

UWB technology enables a convenient and intuitive way to open the vehicle’s trunk—simply through a short foot movement beneath the rear bumper. Unlike traditional capacitive systems, which can be unreliable in rain, snow, or when the vehicle is dirty, UWB offers exceptional robustness and consistent performance in all weather and surface conditions. This precision allows effortless hands-free operation, ideal when carrying groceries or luggage. Beyond comfort and reliability, integrating UWB for multiple in-vehicle applications also reduces hardware complexity and overall system costs.

One UWB Sensor Infrastructure.

X-UWB™ introduces a platform approach for the next generation of automotive UWB systems. It builds on the UWB infrastructure already entering vehicles for secure car access and extends its role beyond opening and locking the vehicle. With radar-capable UWB chipsets, interleaved operation and the right software layer, the same vehicle nodes can evolve from dedicated access hardware into a shared sensing and communication foundation.

Multiple Vehicle Functions.

X-UWB™ enables the same UWB sensor infrastructure to support multiple application domains: in-cabin sensing (including child-presence detection, intrusion detection system and occupant detection system), exterior sensing (including obstacle recognition, kick trunk-opener and parking assistant) and car-to-infrastructure (including EV-charging infrastructure, automated gates and parking garage applications). For OEMs, suppliers and UWB chipset partners, this creates a scalable path to unlock new features, consolidate dedicated sensors and differentiate future vehicle architectures. Additional potential benefits include lower system complexity, BOM, mounting, testing, wiring and ECU-related effort.
