In-cabin monitoring systems (ICMS) are reshaping the concept of passenger safety in cars. Various applications such as left-behind child detection, driver well-being or occupancy sensing increase road safety and the protection in vehicles. Radar in particular is a promising technology to address these applications due to its ability to detect micro-motions and vital signs. 

With XENSIV™ BGT60ATR24C AEC-Q100 radar sensors, AURIX™ microcontrollers and OPTIREG™ PMICs, Infineon Technologies AG offers a wide variety of products for an ultra-wideband, ultra-low power and cost-performance scalable architecture for ICMS sub-systems. The devices support the use of new signal processing techniques enabling robustness and a good compromise between computational costs, the degree of information as well as the power consumption of the system. 

The XENSIV BGT60ATR24C radar sensor is a cognitive sensing solution with multiple transmit/receive for virtual array configurations, a highly agile modulation generation mechanism, automatic power mode configurability as well as simplified interfaces between RF and the processing side. Furthermore, the AURIX TC3xx MCU family combines performance with a powerful safety architecture. The family integrates a fast radar signal processing unit and enhanced security with the second-generation of the hardware security module. This includes asymmetric cryptography accelerators and full EVITA support.

This sensor-MCU combination makes Infineon’s 60 GHz automotive portfolio ideal for ICMS applications. In addition, the partnerships with bitsensing, a South Korean imaging radar technology start-up, and Caaresys, a start-up based in Israel, enables customers to accelerate their development cycle.

“bitsensing’s MOD620, a 60 GHz system solution enabled by advanced signal processing techniques using Infineon’s Chipset Solution, offers a new level of confidence in safety for the automotive industry that demands excellence, reliability and unmatched intelligence,” said Dr. Jae-Eun Lee, CEO of bitsensing.

“Caaresys’ CabinCare and BabyCare radar-based system solutions aim to make life within cars safer. By combining our expertise in algorithms and radar signal processing with Infineon’s high-performance XENSIV 24 GHz and 60 GHz radar sensors and AURIX MCUs, we envision making aesthetic and contactless vital sign monitoring in automotive a reality,” said Ilya Sloushch, CEO of Caaresys.
