60 GHz radar sensors and MCUs target in-cabin monitoring
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 in-cabin monitoring systems (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.
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.
The XENSIV BGT60ATR24C radar sensor is a cognitive sensing device 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 (HSM). This includes asymmetric cryptography accelerators and full EVITA support.
This sensor-MCU combination makes the 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 enabled by advanced signal processing techniques using Infineon’s MCUs, 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.
The MOD620 captures all rear-seat space maintaining the top quality for in-cabin systems. The 120-degree field of view combined with the customizable detection range up to 2.5m provides an increased level of performance. Privacy concerns are also eliminated with the MOD620 as it does not rely on cameras for presence detection.
According to the Heatstroke Deaths of Children in Vehicles, Jan Null, San Jose State University, since the 1990s, 54% of children dying in hot cars was because they were forgotten by their caregivers. The MOD620 prevents this type of casualty by efficiently detecting the presence and vital signs of in-cabin occupants and sending the driver alerts if a child is left unattended inside a car. The MOD620 matches the specific in-cabin requirements for any vehicle offering continuous and limitless detection, regardless of clothes or blankets.
“Caaresys’s CabinCare and BabyCare radar-based systems 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.
